Symantec Data Protection Administration for
I even maintain a confession to make: I’m not constantly blown away through the antivirus software I overview.
over the years, I even maintain discovered to await certain issues from these functions, and that i haven't been terribly shocked by using most types that maintain crossed my desk.
actually, definitions evolve, and the capacity of detection enhance. but for essentially the most part, antivirus software works its magic through comparing what it sees with a static set of definitions, then taking motion when it identifies a match. The interface may too become more intuitive, deployment more painless and detection greater correct, however the process itself continues to live mostly unchanged.
however the newest iteration of Symantec Endpoint insurance policy (v.12) became a nice shock. With SEP, Symantec modified route.
Symantec seems to maintain long past to outstanding lengths to help universal performance by way of training the utility to evade scanning info unnecessarily. To achieve this, it has introduced Symantec insight, technology that uses records collected from greater than one hundred seventy five million choose-in consumers to cost the defense of and allot reputations to well-nigh each executable (.exe) file obtainable. The virus scanner uses this counsel to Make a decision whether to scan a given file. When a reputation ranks enormously, the utility will bypass it altogether, effortlessly minimizing scan instances and reducing typical outfit aid utilization.
moreover, the newest rendition of Symantec online community for advanced Response (SONAR) introduces coverage enforcement, which helps obscure new malicious methods before definitions become available. this is completed through looking at a software’s conduct in precise time whereas leveraging its actions against a behavioral profile. If the culmination of a number of suspicious actions results in a terrible score, the outfit will proactively cease the routine and obviate it from further compromising the computer. Any administrator who has wrung her palms (or pulled his hair out) while looking forward to an endemic definition update will diminutive question value this introduced layer of malware coverage.
Why it works For IT
The administration console is neatly designed and simple to live taught, proposing outfit and information for the all company in a sole panel. administrators who've used outdated models of SEP will locate the design and worthy judgment common, as it is strikingly corresponding to that of v.11. Most common initiatives may too live performed in a all lot the identical routine as they at sum times were, from growing customized guidelines to deploying to new shoppers. Any administrator regular with this product family will haven't any problem getting as much as pace with changes in the new edition.
To aid, Symantec preconfigures the coverage settings of the miniature traffic version of SEP 12. That talent administrators can hit the floor running, making customizations as mandatory.
last, however removed from least, as a result of insight reduces the files scanned and the length of scans, SEP 12’s performance is relatively more suitable on customer methods, resulting in a higher ordinary adventure for conclusion clients.
even though the miniature company version boasts advances, they near at a value. The product turns into a all lot cheaper when a company passes the 25-client mark, and customers acquire further discounts for longer subscription phrases.
Symantec Endpoint protection is a shopper-server software platform that provides layered safety for physical and virtual endpoints geared toward environments with more than 250 users.
the selfsame product, Symantec Endpoint insurance arrangement miniature company version, is designed for smaller environments with more confined administrative support. A cloud-based version -- Symantec Endpoint insurance policy Cloud -- is too accessible for miniature to medium-sized businesses.
this article makes a speciality of edition 14 of Symantec Endpoint protection.

Behavioral monitoring uses computer researching to evade most zero-day attacks, as well as to cease the spread of an infection if an beset breaches community or device security. The vigour Eraser section permits administrators to scan an endpoint from the management console to eradicate an an infection remotely, and outfit Lockdown handles software whitelisting and blacklisting.
Endpoint protection doesn't tender protection to cell devices, and Endpoint insurance arrangement miniature traffic version does not consist of email protection, software manage or aid for digital environments.
The Symantec world Intelligence community, probably the most biggest of its form, analyzes facts from a all lot of thousands and thousands of users and sensors and works with Symantec's insight and SONAR (Symantec on-line community for advanced Response) applied sciences to identify and categorize existing threats.
To enhance efficiency, Endpoint protection makes employ of scan removing and deduplication innovations to in the reduction of the variety of information it maintain to scan on each circulate. extra Endpoint insurance arrangement features then obviate malware and other threats from affecting client endpoints.

We recrudesce to their review of the mobile haphazard panorama with a glance at fresh Symantec cell protection statistics.
What did they deliver?
Symantec sent me some statistics that comes from 2018 and is from an internal evaluation of their Skycure/Symantec Endpoint insurance policy mobile purchasers, which is basically organizations, but some statistics is from buyer employ of their app. a few of their purchasers determine on more locked-down and managed environments, specially these in regulated industries, but they too maintain purchasers that allow BYOD. Symantec can comfy managed and unmanaged devices. lots of the Symantec cellular safety information I obtained is Android concentrated and restricted in scope, but they did deliver one facts aspect for iOS instruments.
MalwareUnsurprisingly, the enterprise is stronger included from malware than client-used devices. Symantec mobile protection information indicates that most efficacious 7.07% of Android instruments in an organization had at least one malware incident in 2018. (Symantec defines an “incident” as the station an app designed to trigger harm is downloaded or Put in on a monitored device; this may too encompass apps that were already installed on a newly enrolled machine.) examine that quantity to the a worthy deal better 22.35% of what Symantec calls “unattached contraptions,” that are gadgets not associated with any organization, rather consumers that downloaded their app from Google Play or the App keep.
but normal, malware is current in below 1% of Android apps that are installed on Symantec-monitored contraptions. They don't import number apps that are merely regarded risky or undesirable that may additionally carry out whatever thing like now not appropriately protect user statistics however is in any other case reliable. (Checking to contemplate how security vendors define “malware” is always first rate.)
Of the Android apps analyzed in 2018 by Symantec, most efficacious .56% acquired a medium or towering haphazard rating, with .fifty four% of apps receiving a low haphazard ranking. Any apps chosen by means of Symantec’s proprietary possibility score to live extravagant or medium potential the machine can too live a possibility to the company and should live remediated. For low haphazard ranking apps, they’re now not seen as probably uncertain and the user’s device received’t glean flagged/remediated; although greater regulated or conservative companies may additionally determine to anyway.
Sideloaded appsFor Symantec consumers, 2.04% of iOS instruments in agencies had at least one sideloaded iOS app. Does look to live relatively low in comparison to the statistics Lookout and Wandera prior to now shared, especially given how light it is set up them.
Android updatesAbout 35% of Android gadgets that can upgrade to the newest OS update (even minor ones) had now not. Symantec did word that “this quantity varies vastly counting on when the statistics become taken relative to when new types are launched.” This makes experience, mainly for the reason that Android releases aren’t at sum times allotted evenly perquisite through the 12 months. also, reserve in intellect that in Android, many devices glean monthly security patches which are demolish away OS updates.
ultimate summon for mobile security information!

Three of the gigantic headlines so far this year maintain been data growth, the economy and data deduplication in backup. The first headline, relentless data growth, is the root cause of most issues in the backup environment. In an exertion to meet service-level agreements (SLAs) for data backup and recovery, more and more organizations are deploying disk in the backup process. With disk, IT organizations can better meet backup windows and recovery objectives. But as IT "modernizes" its backup infrastructure with disk-to-disk backup, new problems emerge -- specifically, the cost of managing copies stored on disk, and the feasibility of taking disk-based backup copies and making them portable for offsite and/or long-term storage.
Deduplication addresses the first issue -- it changes the economics of disk-based backup, allowing more data to live stored in a smaller footprint. The second problem is the new pain point for halt users that maintain adopted disk. How can they rapidly, securely, cost-effectively, and efficiently glean data offsite for cataclysm recovery (DR) or long-term retention? Sure, most target devices with deduplication can replicate copies, but is the backup application's catalog aware of the copy? That's where Symantec Corp. Veritas NetBackup OpenStorage (OST) technology comes in.
Symantec announced its NetBackup OpenStorage initiative a few years ago. It is designed to allow NetBackup users to utilize third-party storage solutions without the requisite for tape emulation.
Available as an option for NetBackup 6.5 and higher, NetBackup OpenStorage gives NetBackup a common interface for third-party disk targets. NetBackup sees OST-enabled appliances as disk, enabling features such as brilliant capacity management, media server load balancing, reporting, and lifecycle policies. It too delivers optimized duplication. Without OST, NetBackup media servers maintain to manage sum duplicate backup copies, which means that data must live transferred across the LAN, WAN, or SAN from the primary site secondary storage to a NetBackup media server and then to the cataclysm recovery site storage medium (i.e., another appliance of the selfsame ilk or tape media). With OST, the OST-enabled device is doing the replication and the data path does not embrace NetBackup media servers. This means that only changed segments are replicated, creating savings in bandwidth and, importantly, time. NetBackup is aware of sum copies and those copies follow established retention policies.
Symantec Technology Enabled Program (STEP) partners -- such as Data Domain, EMC Corp., FalconStor Software, and Quantum Corp. -- leverage the NetBackup OpenStorage technology API to create plug-ins for their storage systems. OST allows for backup data to live stored on disk with whatever protocol the target device uses, such as a Fibre Channel or TCP/IP. Based on NetBackup policies or commands, the OST-enabled device will create, duplicate or delete copies.
One of the more appealing byproducts of the employ of the NetBackup OpenStorage interface is the performance improvement in backup. Several STEP partners with an OST-enabled solution title 50% to100% improvement in backup performance. Richard Nosal, a server administrator for towering Point Regional Health System in Greensboro, N.C., implemented the NetBackup OST option with a Data Domain DD660 and saw his pre-OST 10-hour backup window with a virtual tape library reduce in half.
Since the NetBackup catalog is aware of sum copies, recovery of data from a NetBackup OpenStorage-optimized duplicate copy is the selfsame as recovery from another duplicate. Through NetBackup's Backup-Archive-Restore GUI, the OST-optimized duplicate copy can live designated as the primary copy and then a replete or granular recovery can live initiated. The potential time savings over recovery from a non-OST-optimized duplicate could live significant.

The countdown to Windows 8.1 is officially on. Whoever thinks that Windows 8.1 is squarely a consumer-centric release is heavily mistaken. After spending a month with Windows 8.1 Pro on my Thinkpad X230 Tablet, I can definitively hiss that Windows 8.1 is shaping up as a rock-solid option for the enterprise. I've previously written about why businesses should maintain been considering Windows 8 for their next upgrade cycles. With 8.1, Microsoft's latest OS is a service pack on more than a few steroids.
By any measure, I've been a vocal, bullish early adopter of Windows 8. My day to day consulting work for customers doesn't allow me to sojourn stuck on previous generations of Windows. Even if I did prefer Windows 7, my mixed client basis is touching to 8 whether I like it or not. I requisite to live prepared for the questions and troubleshooting that ensues, which means I requisite to live their resident Windows 8 expert.
And I won't lie: Microsoft has pleasantly surprised me with Windows 8. Even on a non-touchscreen Thinkpad T410, my experiences with the new OS maintain been generally positive. Sure, my initial foray was met with skepticism and a twitch wish for the musty and familiar, but I got past the mental speedbump and haven't turned back.
I readjusted my workflow when I made the switch off Windows 7. intellect you, I spend about 90 percent+ of my time in the Desktop interface on 8 (and recently, 8.1) and after a few hours of hunting for the Start button, I started to hold handicap of the fruits that 8 offers. Searching for what I requisite instead of pecking through menus or organizing rows of shortcuts. Making employ of the Charms. After a while it hit me: this new interface just made sense. I found myself saving time on mundane tasks that were otherwise nestled in click-here, click-there combinations.
My day to day work is highly dynamic and the needs of the hour determine what I'm working within. One minute I'm administering a server over Remote Desktop or helping a customer with their live support tool, ScreenConnect. The next I'm cranking out a proposal in Google Docs. Perhaps working on my company's financials in QuickBooks Online. pitch in some Hyper-V and VirtualBox usage for testing different OSes, and round out my day doing some number crunching in Excel. I maintain yet to pitch a employ case scenario at Win 8 that didn't feel perquisite or work as expected. I too cannot recollect a sole "Blue Screen" since jumping ship from Windows 7.
This transition for the Microsoft OS ecosystem is no doubt a generational one. Not unlike Office when the Ribbon trashed the menu-heavy interface in version 2007. Not unlike how XP completely transformed the Start Menu from the die-hard Classic look/feel of Windows 2000. And to a lesser extent, not unlike Windows 3.1 which slapped a replete GUI on us and rejected the notion that "everyone wanted DOS". I'm soundless not certain why companies like Apple can toss the revolutionary iOS on a generation of users without a hint of an uproar, and Microsoft is held to a last-generation expectation from the masses. Double standard, anyone?
Just two decades ago, the command line of DOS gave way to the first wave of Windows GUI desktops in the workplace. soundless yearning to rush back -- for musty time's sake? The removal of the traditional Start Menu is no different in conceptual progression. (Image Source: Microsoft)
Enough with the soapbox. Windows 8.1 brings a ton of new functionality to the table for the business, government, nonprofit, and education sectors. And the best section about the new OS? It's completely free. As in zero dollars, zero cost, you cognomen it. Businesses that maintain already either partially or fully moved to Windows 8 will live able to glean the update at the selfsame cost of free as any consumer. This goes for organizations who too leverage Software Assurance or Volume Licensing for their Microsoft software rights. If you maintain licensing for Windows 8 or are getting access soon, you will live eligible to Make the rush to 8.1 at no charge. As you'll contemplate below, there are few reasons not to hold advantage.
So what are these well-kept new functionalities that Microsoft has baked into Windows 8.1? Here's a closer examine at the ones I contemplate as most relevant, divided into ratiocinative sections so you can peruse by category with ease.
Windows 8.1: Security
Drive Encryption for Everyone: Microsoft is lifeless sedate about encryption security for Windows 8.1. That's why every edition of Windows 8.1 will maintain the underlying technology behind BitLocker baked in, with the Pro and Enterprise flavors getting replete administrative control as was the case previously in varying extent since Windows Vista. Upon login with a Microsoft Account, any Windows 8.1 machine will maintain encryption for the main OS drive turned on by default. This is excellent intelligence for medical offices who are facing the mad dash towards IT HIPAA compliance.
Remote Selective Data Wipe: Up until now, BYOD in the workplace has been a pain in the rear. When it comes to differentiating access to corporate data, traditional VPNs and share permissions off servers maintain done diminutive to paint the black and white lines of what employees should reserve and what needs to glean returned once a worker leaves a business. They deal with it sum the time in my consulting business. The next best thing to completely blocking BYOD has been Windows Remote Desktop Services, leveraging Session Based Desktops, but this doesn't meet everyone's needs.
Remote Selective Wipe in Windows 8.1 allows companies or organizations to specify what data is owned by the employer and should glean wiped or indefinitely locked on the halt user's device when they leave. This means companies can dole out more bountiful access to faultfinding data without fretting about what will glean plucked when a valuable employee gets picked up by the competition. This helps reduce capital investment in laptops/tablets while enabling for a secure approach to BYOD which has never been offered on such a pervasive scale before.
Work Folders to Simplify File Access: The way they used to dole out file access to users was never intended for the modern BYOD workplace. Offline Files, remote VPN access, etc were sum poor band aids to a gigantic problem: how can workers glean access on the rush with relatively diminutive effort, without ruining file synchronization on the server? work Folders in Windows 8.1 (coupled with Server 2012R2 on the backend) solves this brilliantly. The technology is a lot like what SkyDrive offers on the personal and Office 365 side of things. Files can glean assigned and synced to user devices for on-the-go editing access, and when an internet connection gets restored, the files are streamed and synced back to the central server. Remote file access that finally just works.
Work Folders bring the power of SkyDrive-esque technology to the indigenous Windows 8.1 undergo specifically for the workplace. Microsoft's cruddy Offline Files technology finally bids a long overdue farewell. (Image Source: Microsoft Channel9)
Microsoft has a powerful overview video of the tech on Channel9 as well as a nice in-depth writeup on TechNet.
Workplace combine is like AD-lite: It was either you were on a Workgroup or an AD Domain -- and that was it. Not anymore. Windows Workplace Join allows sysadmins to provide a "purgatory" of sorts that is not quite replete AD, but not as loose as being joined to a Workgroup. You can watch a replete demo of how simple this technology works from this year's BUILD 2013 conference.
Native Biometric Recognition Support: Fingerprint readers maintain been a mainstay for traffic line laptops for years. Most Thinkpads I maintain owned over the ultimate ten years maintain had one. The problem is, they always required additional vendor software to employ the functionality. This increases overhead, administrative effort, and in the end, too increases likelihood for issues over the long run. Which is one of the reasons why biometric uptake has been slack on Windows. Windows 8.1 has indigenous fingerprint and virtual smart card support out of the box to secure the logon process. About time, Microsoft.
Network deportment Monitoring in Windows Defender: While Defender solitary should not live considered a comprehensive security solution, the fact that it will now maintain some HIPS functionality (Host Based Intrusion Prevention System) is reassuring. My company's favorite AV product, ESET NOD32, has had HIPS functionality since version 5. Microsoft is claiming that in Windows 8.1, Windows Defender will live able to spot suspicious network deportment from both known and unknown threats alike.
I wouldn't hinge my entire company's security arrangement around it, but it is reassuring to know that every 8.1 system out of the box will maintain a fairly decent plane of protection from modern complicated threats natively.
Assigned Access for Dirt light "Kiosk Mode": This new feature is especially nice for the education and traffic sectors. Previously, when organizations wanted to restrict access to a sole interface -- for example, a web browser locked to a certain site or a given app -- they had to leverage combinations of complicated Group Policies and/or AppLocker rules. These solutions worked, but boy, the amount of legwork and testing required made even the seasoned IT sysadmin sweat.
Assigned Access, which is available in Windows 8.1 RT, Pro, and Enterprise allows for admins to lock down an 8.1-powered device to function within a single, designated Windows Store app. It could live a reading application for Surface RT tablets in K-12 education. Or perhaps a line of traffic program for a sales oblige out in the realm on convertible tablets. The uses are near limitless.
"The Most Secure OS Ever Made": According to Microsoft, Windows 8 is 21 times safer than Windows XP, and 6 times safer than Windows 7, from a malware infection perspective. Renowned AV vendor ESET has said similar praises about Windows 8 being the "most secure version of Windows ever." After years of clamor about a mass exodus from Windows to Mac due to security, researchers are coming out and claiming that Macs maintain nothing inherently more secure about them, and new malware that hit OS X earlier this year is continuing to note the cracks in Apple's security-by-obscurity approach. For the enterprise stuck on an imploding island of XP machines, Windows 8.1 is looking like a much better replacement than Windows 7 or Mac.
Security in Windows 8.1 is a gigantic deal. Security researchers maintain already begun saying that government agencies looking to upgrade to Windows 8 are making a "good move." And seeing that Microsoft has promised support for Windows 8 (and 8.1) through Jan 2023, the OS will bask in a plush 10 year lifespan for organizations that Make the rush now.
Windows 8.1: Networking & RDS
Big Improvements for RDS: When used in conjunction with Server 2012 R2, Windows 8.1 with Remote Desktop Services Session Host Desktops (RDSH) allows for well-kept extended capabilities. For example, sysadmins and IT support staff can now actively view and control user desktop sessions to provide aid desk style support and retort questions on functionality through Session Shadowing. The networking side of RemoteApp has been markedly improved even further, allowing for crisper usage of RDS-hosted RemoteApp programs in low bandwidth scenarios like on mobile 4G cards or at wifi hotspots. RDS on 8.1 too finally introduces multi monitor support for users, significance that "Terminal Services" doesn't maintain to live a second class experience. This too includes replete feel capability for RDS sessions!
New Simple Printer Connection Options: Two new wireless-enabled printing capabilities are being added natively to Windows 8.1. The first, Wi-Fi Direct, allows anyone to connect a mobile device to a Wi-Fi Direct printer to leverage ad-hoc printing without the requisite for drivers or an existing wireless network. NFC tap-to-pair printing is very similar, and can allow an NFC device like a smartphone to merely "bump" a printer that has an NFC tag placed on it to establish a simple direct printing connection on the spot.
Easy Hotspot Creation from your PC: Internet Connection Sharing has been around for a long time. But it's been a junk feature for as long as I can remember. difficult to configure, and even more difficult for others to leverage. Windows 8.1 brings the notion of light hotspot creation to every PC, which is powerful for situations where, for example, staff members are trying to share a sole wired LAN connection at a conference margin before a sales presentation. Wi-Fi isn't ubiquitous or free everywhere yet, so this is a welcome new feature for mobile road warriors.
Auto-Triggered VPN Access: We're sum used to the errors and access issues presented by applications they just forget that requisite VPN access to the corporate network when in the field. Windows 8.1 looks to resolve these dilemmas once and for sum with Auto-Triggered VPN settings that can prompt for necessary VPN credentials whenever certain items necessitate them. Forgetting to connect to the VPN won't halt up in a molasses-crawl to the expected "access denied" prompts anymore.
Better Out-of-Box VPN Client Support: You can cross four vendor VPN application add-ons off the list of programs needed to glean onto the corporate network. Microsoft has caked in indigenous support for SonicWall, Juniper, Check Point, and F5 VPN firewall connectivity. You check check out the short spiel on this from the BUILD 2013 event on Windows 8.1.
Simplified, light Management of Devices in Windows Intune: Windows 8.1 and 8.1 RT brings the next progression of Windows Intune to the forefront, allowing for unified centralized cloud management of sum your Windows devices. Schools, nonprofits, and businesses can sum profit from such management capabilities, especially on the Windows RT side where devices cannot live natively joined to dynamic Directory. What used to live relegated to MSC 2012 for an on-premise server is now extended fully to the cloud with Intune.
This is excellent intelligence for organizations with diminutive budget for capital expenses on servers and extensive setup labor. Intune comes in as cheap as $6 USD/month for licensing without Software Assurance -- a real bargain compared to some BYOD management suites.
Windows 8.1: UI & Functionality
Smart Search: If you happened to bask in the excellent built-in search capabilities in Windows 8, then 8.1 is not going to let you down. The selfsame speedy, integrated search undergo soundless exists and permeates in Windows 8.1, but is brought to the next plane via Bing inclusion. This means you can search for anything from the Modern UI interface. ultimate week's fiscal spreadsheet, your family photos from vacation, the apps you employ day to day, and internet-powered results for items like news, weather, research material, etc. Paul Thurrott goes into excellent detail on this functionality on his blog.
Windows Button "Right Click Menu": The fact that the Start Button is back in a limited form is musty news. The best section about the new Start Button is the hidden "right click menu" that provides a juicy amount of light access to numerous functions most IT pros hold for granted. Heck, many of these items are now easier to glean to then they were in Windows 7. This not-so-secret menu makes it simple to shut down your machine, open command prompt, or a bevy of other options. Yes, this easter egg of sorts existed in stock Windows 8, but the addition of the new power-related options Make this revised menu a keeper. contemplate below for more information.
Boot Straight to Desktop Mode: This is awesome intelligence for workers like me, that spend a majority of their time in the Desktop interface and only dabble onto the Modern UI for a diminutive after-hours activity. In 8.1, anyone can configure their PC to boot straight to the intimate desktop interface, significance you can glean straight to work, bypassing the Start Screen entirely. A small, but timely, touch.
Just as Fast, Just as Slim as 8: This isn't necessarily a feature per-se, but it's one heck of a nicety. Not only does Windows 8.1 maintain the selfsame exact hardware requirements as Windows 8 - but these betide to live the exact selfsame requirements as Windows 7 had. What gives? Microsoft has created a lean mean, processing machine in Windows 8 and the trend continues. While I don't maintain any difficult numbers or results to back it up, my non-scientific feelings lead me to believe that 8.1 runs smoother than 8, most notably on startup and shutdown. SSD users are in for a blazing posthaste experience. You will likely miss the new boot screen with the funky Betta Fish if you don't examine carefully.
This too means that those computers which would maintain otherwise gotten canned at the office can more than likely glean upgraded to Windows 8.1. Seeing that Windows 8 did away with the recollection and battery intensive Aero interface, you will too ideally contemplate better pound-for-pound standard usage performance from Windows 8.1 then you otherwise would with the selfsame specs loaded up on Windows 7.
The bloat that Microsoft was known for from Windows 2000 to XP, then from XP to Vista is a thing of the past.
Miracast for Wireless display Projection: Miracast is an open alternative to (but fully compatible with) Intel's WiDi technology that started the wireless projection market. Windows 8.1 has this well-kept technology built perquisite in, which means if you maintain a Miracast enabled projector in the board room, but your laptop doesn't maintain the DisplayPort connection that it needs, you can employ Miracast to setup a Wi-Fi Direct signal to the unit in order to present your material. Xbox One has this built in as well, and many new displays and projectors are promising to bundle this technology going forward. Could this live the birth of the halt for cable and dongle-heavy board rooms? Time will tell.

Windows 8/RT Store Not a Ghost Town Anymore: The media kept rubbing Windows 8 for not having much of a useful Windows Store at launch ultimate year. How the tables maintain turned. While the situation is not on par with what Android or iOS have, the fact that Windows Store now offers 54% of the top 100 iOS apps is pretty commendable 10 months in. As of September 1, the Windows Store had over 114,000 apps and counting. The list will only reserve growing as time goes on.
Internet Explorer 11 is Faster, Safer: As if a new Internet Explorer release was ever missing those two descriptions, IE11 promises a diminutive bit of "better everything." Faster load times, better compliance with web standards and HTML5, side-by-side browsing of sites, and deeper anti-malware integration for catching nasties before they are even allowed to launch. For companies that rely on a strict policy of IE due to corporate protocol or ease of administration, IE11 will live a no brainer to Make life easier on the end-user and management fronts.
Surface RT gets Outlook 2013 with 8.1 RT: A lot of intelligence outlets are forgetting to cover this factoid, but for traffic professionals leveraging the Surface RT, they should know that Outlook 2013 is launching alongside Windows 8.1 RT for the Surface RT. Free of charge, of course. This means Office 365 users who maintain Exchange Online accounts, or other IMAP/POP users, can easily connect their email to arguably the most powerful email and organization app ever made for the computing world. I'm rolling out Surface RT tablets at some of my customer offices, and this will Make the product even that much more attractive for the workplace.
3D Printing support Out-of-the-Box: Not the biggest deal for most businesses (yet), but if the 3D printing revolution ever takes off, Windows 8.1 has the necessary hardware/software support built in to leverage the technology natively. My only undergo with 3D printers was at my musty school district job, where the Applied Arts department had one that could Make CAD-developed prints out of plastic in 30-60 min timeframes. Perhaps the newest generation of these units are much more dazzling in wait times. I await numerous markets to start taking handicap of the dropping cost points and improving technology to bring their once fanciful creations to life.
Multi Monitor support that Rocks: I thought my dual screen capabilities were awesome in stock Windows 8, but 8.1 just takes it to a all new level. Dragging and dropping individual Modern UI apps to different screens is fully supported for the first time. The Start Screen can live accessed via Charms that work on any screen now. The taskbar can live fully extended over a sole set of monitors as well. And the plane of customization that is now inherently provided for snapping and resizing Modern UI apps and your Desktop interface are limitless. Multi monitor workstations will greatly profit from Windows 8.1 -- further creating screen begrudge among your coworkers.
Prefer to employ a hybrid Desktop-Start Screen setup with your dual screens? Such new combinations, and more, are finally workable in Windows 8.1. Microsoft has taken multi-monitor support to the next plane and truly created a customizable undergo worthy of what Windows 8.1 offers. (Image Source: Microsoft TechNet)
(Even) Better Battery Life: My day-to-day Thinkpad T410 got a boost of about 30-45 mins when I made the switch from Windows 7 to Windows 8 ultimate fall. Pretty significant. While I don't maintain as much data to back up a statement on Windows 8.1, naturally, Microsoft is saying that OS is taking gigantic handicap of the power saving capabilities in Intel's Haswell platform. I'm itching to contemplate how the final RTM build handles my Thinkpad X230 Tablet as my new primary mobile workhorse, but the 8.1 Pro Preview has been giving me a solid 6 to 6.5 hrs of life on an 8 cell battery. Impressive for a pre-release, buggy iteration.
Hand-in-Hand SkyDrive Integration: It's no astonish that Microsoft is tightly combining the features of SkyDrive Personal into Windows 8.1. The cloud storage utensil is a worthy competitor to Google Drive; and heck, I employ it now for sum of my personal Office document storage because it just works cleaner than Drive due the fact that I can leverage Office Web Apps on the rush when I requisite to. SkyDrive is now a persistent default deliver location for numerous functions and apps in Windows 8.1, going beyond what Office 2013 brought to the desktop in terms of pushing SkyDrive. Hey -- there's life beyond work, after all.
Auto foretell for feel Typing / Tablet Mode: For those using Windows 8 on tablets, like the Surface RT, typing in feel mode was a bit of a chore for a requisite of proper auto predict. Windows 8.1 resolve this quite nicely. Now, you can continue typing and employ predictive suggestions from the OS with complete ease. This means that Surface RT users in the realm within tablet mode shouldn't maintain to rush into laptop mode that often anymore for short-spanned typing. Should Make Word 2013 a snap to employ without the cover opened!
Windows 8.1 hits the market officially for everyone near October 17, and is a completely free update for all. My company will definitely live recommending 8.1 for both consumer and traffic usage as time goes on, especially if the wonderful improvements from the Preview translate into real-world profit for halt users near October.
I'm calling it now: Windows 8.1 is the new Windows XP for the workplace. Just watch.

This chapter, from Upgrading and Repairing Networks, 5e, looks at the network's ratiocinative and physical design to assist your planning when creating a new network.
This chapter is from the bespeak
Many types of networks were discussed in Chapter 1, "A Short History of Computer Networking," from ARPANET to TCP/IP. And in Chapter 2, "Overview of Network Topologies," you learned about the various topologies you can employ when designing and creating a local locality network (LAN), and they too looked at some scenarios in which several networks were connected to form a wide locality network (WAN). In this chapter, they will examine at another aspect of creating a network: the network's ratiocinative and physical design. The physical aspects of your LAN will depend on the underlying physical transport technology—Ethernet or Token-Ring, for example, or possibly ATM, which is supported as a LAN protocol in products such as Windows 2000/XP, Windows Server 2003, and Linux. Depending on which technology you use, there will live one or more LAN topologies from which to choose.
Before you can open to design a physical network, however, you first must determine your needs. What services must you provide to your user community? What are the resources you'll need? If you maintain to compromise, what will it hold to fill the most users or to provide the more principal services? You then will maintain to hold into account network protocols, applications, network speed, and, most important, network security issues; each of these figures into a network's ratiocinative design. Another principal factor your management will probably oblige you to reckon is cost—you can't forget the budget. These factors Make up the ratiocinative design for your network. You first should determine what you requisite and what it will hold to provide for those needs.
If you are creating a new network and purchasing new applications, you will probably spend most of your time considering the licensing and other fiscal costs (training users, network personnel, and so on). If you are upgrading older applications, several other factors near into consideration. Many applications that were coded using COBOL, BASIC, FORTRAN, and other languages that helped jumpstart the computer age may maintain built-in network functionality based on older proprietary network protocols. If this is the case with your network, you maintain to reckon several things. What will it cost to update thousands of lines of code (or more) to more modern versions of the selfsame programming language? What will it cost to upgrade these programs to newer object-oriented languages? To deliver money, can you upgrade section of your network and employ gateway hardware/software to connect to older network components?
Because of the costs associated with coding applications that were created many years ago, and the expenses that will live required to update them to modern programming languages, you may live forced to maintain legacy applications for a few years while replacement applications are designed and created. You may find a packaged application that can live used to supplant older programs. This problem will apply mostly to proprietary computer architectures, instead of Windows or Unix platforms. If you can simply Make minor changes and compile the source code so that it will elope on a newer operating system, your costs will live much less than if you maintain to re-create the applications your users requisite from scratch. Another cost associated with upgrading to new programs is training users and help-desk personnel.
When you arrangement a ratiocinative network design, you can start from one of two places. You can design and install a new network from scratch, or you can upgrade an existing network. Either way, you should amass information about several principal factors before you open the ratiocinative design. For example, depending on the services that will live provided to clients, you might requisite to anatomize the workable traffic patterns that might result from your plan. Locate potential bottlenecks and, where possible, alleviate them by providing multiple paths to resources or by putting up servers that provide replicas of principal data so that load balancing can live provided. The following are other factors to consider:
Who are the clients? What are their actual needs? How maintain you determined these needs—from user complaints or from help-desk statistics? Is this data reliable?
What kinds of services will you provide on the network? Are they limited in scope? Will any involve configuring a firewall between LANs? And if so, that soundless doesn't account for configuring a firewall to enable access to the Internet.
Will you requisite to allow an Internet connection for just your internal network's users, or will employ you requisite to allow outside vendors access to your network? One instance that comes to intellect is the Internet Printing Protocol (see Chapter 24, "Overview of the TCP/IP Protocol Suite"). What will it cost to evaluate what benevolent of services user groups requisite to access from the Internet? Will you requisite to allow sum users to employ email—both within the internal network and through the firewall on the Internet? The selfsame goes for what sites users will live allowed to access using a network browser and other network applications. Will you maintain users who work from home and require dial-in or VPN access through the Internet?
Can your users tolerate a diminutive downtime now and then due to network problems, or is it necessary to provide a high-availability network? Will you requisite clustered servers to provide for a towering degree of uptime, or carry out your users' applications not suffer from a temporary loss of the employ of a server? To provide for maximum uptime, can you afford to build redundancy into your network? For example, Chapter 2 discusses redundant topologies that can live used to obviate a sole point of failure from making the network (and its resources) unavailable. Chapter 11, "Network Attached Storage and Storage locality Networks," describes methods you can employ to mirror data at geographically far-off locations.
In an existing network, will you reserve the current protocol or upgrade to a different protocol standard? If you create a network from scratch, what factors should strike your network protocol decision? Ethernet is the most Popular LAN technology in the world today. TCP/IP is the most Popular protocol suite that runs on Ethernet. Yet there are cases in which other technologies maintain their niches. reckon the implications (such as support costs and security) to maintain older, proprietary protocols.
Who Are Your Clients?
This seems like a very simple question. However, I'm not saying, "What are your clients' names and how well carry out you know their children?" I am referring instead to your erudition of the job descriptions for the users on the network. You requisite to assess work patterns for various departments so that you can appropriately station servers, high-bandwidth links, and other such things in the arrogate physical location of the network. If most of the network traffic you await to contemplate will near from the engineering department, you'll requisite to provide that department with a large data pipe. In Chapter 4, "Upgrading Strategies and Project Management," you'll find more information about surveying the user community to near up with a arrangement that places resources where they are needed.
What Kinds of Services or Applications Will the Network Offer?
Of course, everyone knows that the most principal function of a network today is to support multiuser gaming. Seriously, though, you requisite to Make a list of the kinds of applications currently in use, as well as a list of those requested by users. Each application should maintain a written risk assessment document that points out potential security problems, if any. Typical network applications today embrace FTP, telnet, and, of course, browsing the Web. There are "secure" versions of these applications and there are versions that leave a door wide open into your network. Whatever list of applications you chose to support over the network, reserve in intellect two things:
Is the application safe? Most applications today near in secure versions or can live used with a proxy server to aid minimize the possibility of abuse. Yet, as they sum maintain seen, even the largest corporations are targets at times, and those companies maintain the staff that should live able to obviate these things from happening. Because proxy servers are an principal component of firewalls, this matter is covered in greater detail in Chapter 45. If you want a secure network, this is highly recommended reading!
Does one application overlap another? Every user has his or her favorite application. Some people like one word processor, whereas others prefer a different one. But when dealing with applications or application suites (such as Microsoft Office), you'll find it better to Make a decision and stick with a sole product if it can fill the needs of your users. They might not like it, and training might live necessary, but supporting multiple applications that carry out the selfsame thing wastes money and leads to confusion.
A commonly overlooked routine for getting data files out of a network and onto the Internet is to simply dispatch the files as an attachment to an email. So if you cogitate you've blocked file transfers by disabling FTP access through the firewall, this instance should note that you really carry out requisite to carry out a thorough evaluation of any new application or service you will allow on the network. new applications should live justified with facts that note why they are needed. If an existing application can live used to accomplish the selfsame goal, why carry out you requisite another application? Should you retire the older application and employ a newer one? Pay attention to the details. And don't forget to test new applications to ensure that they effect as expected. The selfsame goes for older applications—will they work on the new or upgraded network?
Lastly, carry out you monitor network usage? carry out you want to permit users to spend their days browsing the Net, or checking personal email while at work? Many companies maintain policies that apply to using the telephone for personal business. carry out you overlook this situation when giving users email capability? Are you preventing access to sites that are obviously not business-related?
What Degree of Reliability carry out I Require for Each Network Link?
Just how much downtime is acceptable? For most users, the retort would live zero. principal components of your network, such as file servers, should maintain fault tolerance built in from the bottom up. In large servers, you'll find dual-redundant power supplies (each connected to a separate UPS), and disk arrays set up using RAID techniques to provide for data integrity in the event that a disk goes south. If a link between two offices needs to live up 100% of the time, you should arrangement for multiple links between the two sites to provide a backup capability. In this case, you too can warrant the cost of the extra link by using load balancing so that network response time is improved. And, if you are using multiple links to remote sites, it's always a worthy concept to maintain more than a sole path to the site. At one site this author worked at, there were redundant power lines bringing electricity into the site—side-by-side. If a tree falls, will it bring down one or both of those power lines?
Another technology that can live used to provide an extra layer of redundancy, as well as high-speed access to storage devices, is the Storage locality Network (SAN). A SAN is a network that is separate from the LAN and contains only storage devices and servers that requisite to access those devices. Because the network bandwidth is not shared with LAN users, multiple servers can access the selfsame storage. If one server fails, other servers can live configured to provide redundant access to the data. Also, the selfsame RAID and other redundancy techniques used for storage devices that are directly attached to a server (such as the SCSI hardware and protocols) can live used on a SAN.
The terms RAID and UPS are principal in today's networks, as is the concept of load balancing and dual-redundant power supplies in large networks. You can find out more about RAID (Redundant Array Of Independent Disks) and UPSs (uninterruptible power supplies) by reading Chapter 5, "Protecting the Network: Preventative Maintenance Techniques." For more information about SANs, contemplate Chapter 11.
The musty saying "If it ain't broke, don't fix it" doesn't apply to networks. You should always live proactively looking for potential sole points of failure and doing something to fix them. By edifice redundancy into the network design at the start, you'll deliver yourself a lot of grief in the future.
Chapter 5 can give you more suggestions about using clustering, backups, uninterruptible power supplies, and other techniques that can reserve the network up and running.
Choosing a LAN Protocol
Today the de facto protocol of choice has to live TCP/IP. However, other protocols maintain their station in some vertical markets. In this book, they talk about NetWare. NetWare has been around so long that you might find you maintain no choice when designing an upgrade but to reserve using IPX/SPX, depending on the applications your network uses. However, even NetWare has moved toward using TCP/IP as the underlying protocol. This is basically the case for version 5.x and 6.x of NetWare. Older NetWare networks should upgrade, if possible, to one of these newer versions. If you will live connecting the network to the Internet, TCP/IP will live a necessity. Even if you don't await to maintain an Internet connection, you'll find that choosing TCP/IP is a more practical choice today because most applications work with it and there is a large market of trained professionals who can live hired to manage a network built on TCP/IP. NetWare 6.x provides backward compatibility with IPX/SPX for the most part, but newer features such as the iPrint—which uses the Internet Printing Protocol—require TCP/IP.
In addition to transport protocols such as TCP/IP and IPX/SPX, you must reckon application protocols that can live used on the network. For example, to simplify administering configuration information for a large number of computers, you might want to employ the Dynamic Host Configuration Protocol (DHCP), which is discussed in Chapter 28, "BOOTP and Dynamic Host Configuration Protocol (DHCP)." If you want to provide a central cognomen resolution service, you might choose the Domain cognomen Service (DNS), which is covered in Chapter 29, "Network cognomen Resolution." If you are going to operate a Windows network that has pre–Windows 2000/XP clients, you might requisite to employ the Windows Internet Naming Service (WINS) for backward compatibility.
So when thinking about a network protocol, recollect that it's not just one protocol you requisite to worry about. After you've decided which protocols are necessary, research the security implications of each.
It's Virtually Universal: TCP/IP
For sum practical purposes, the standard LAN protocol today is TCP/IP. This is partly due to the rapid growth of the Internet, and the necessity of most businesses of having a Web presence, as well as the large number of vendors that maintain adopted this protocol suite. If your LAN is soundless using an older proprietary network protocol, you should seriously reckon what it would hold to upgrade to TCP/IP. Currently, TCP/IP version 4 is the most widely used protocol. In the future you can await that the next version (IPv6) will start to find its way from the core of the Internet out to the edge, where your network resides. While technologies such as Network Address Translation (NAT) are widely employed to remedy the problem associated with the limited address space provided by IPv4, IPv6 will enable a much larger address space. Combine that with Network Address Translation, and the long-term bets are going to live on IPv6, or possibly some of the features that are section of IPv6. In addition to giving you a larger address space, IPv6 includes other principal features. Those that will strike your network the most are security mechanisms, which will only become more principal as Internet commerce continues to grow.
For a circumstantial introduction to TCP/IP, contemplate Chapter 24, "Overview of the TCP/IP Protocol Suite"; Chapter 25, "Basic TCP/IP Services and Applications"; and Chapter 27, "Troubleshooting Tools for TCP/IP Networks."
There is one very principal reason you should reckon TCP/IP as a LAN protocol: There are more trained professionals knowledgeable in TCP/IP than any other LAN protocol at this time. It is appealing to note that in Windows NT 3.51, the default network protocol was Microsoft's implementation of IPX/SPX (NWLink). In Windows NT 4.0 (and successive operating systems, from Windows 2000, XP, and Server 2003), the default network protocol is TCP/IP.
If your network is composed of several operating systems, from Windows to NetWare to Unix and Linux, then the bottom line is that TCP/IP is the lowest common denominator that will allow the easiest connectivity and interaction between sum of these. Even Microsoft's now-legacy NetBIOS/NetBEUI protocols maintain been adapted to elope over TCP/IP.
Novell's NetWare Version 6.5
NetWare was perhaps the first attempt at seriously providing a LAN protocol that was light to use. The basic file and print services offered by early versions of NetWare were much better than other solutions available at that time. After it became established in the traffic community, NetWare became the network solution of choice in many traffic environments that used the PC. Microsoft countered this success with its LANManager products, which were too marketed by other vendors in their own way, such as the Pathworks solution from Digital outfit Corporation.
Today NetWare is a totally revamped solution to LAN connectivity. It provides many new features that are addressed to specifically Make employ of the Internet, and allow mobile users to connect to their home networks, as well as to enable NetWare users to Make connections to outside networks. For example, the iPrint feature enables NetWare users to print to a printer on a remote network. For example, instead of sending a catalog that may live out of date in a month or so, you can employ iPrint to periodically dispatch specific information relevant to each customer, by printing it directly to the customer's printer.
And NetWare's iFolder allows mobile users to synchronize data stored on remote computers (such as a laptop computer) with the data stored on the company's network. Microsoft and other vendors tender similar features. However, the point to recollect is that if you already are a NetWare user, you don't maintain to pitch out your existing investment and rush to a Microsoft network, or even a Unix/Linux environment. NetWare has changed as the market has changed, and you might find it less expensive to upgrade to NetWare 6.5 than to migrate to another platform. The bottom line involves not just the cost of migrating to another operating system, but the costs involved with retraining your network administrative personnel in new technology.
Because NetWare 6.5 is so tightly integrated with the IP protocol, and too offers backward compatibility with IPX/SPX, admins for existing NetWare networks should reckon upgrading to NetWare 6.5 as well as considering other options.
If you want to rush to Linux, Novell makes it light by incorporating an enhanced version of NetWare 6.5 and SuSE Linux into its Novell Open Enterprise Server. Open Enterprise Server supports both Linux and NetWare-specific software and features, enabling you to rush to Linux gradually.
Other LAN/WAN Protocols
The distinction between LAN and WAN (wide locality networking) protocols is birth to blur. Ethernet was once considered to live a LAN protocol. As time has passed, other technologies, such as Token-Ring, maintain become minor players in the LAN world. Yet the opposite is True of Ethernet. It has grown from a modest specification endorsed by Intel, DEC, and other vendors, such that it now can live considered a WAN protocol. The capabilities introduced by current LAN technologies are birth to erode the differences between a LAN and a MAN (metropolitan locality network). When the fourth edition of this bespeak was published, Gigabit Ethernet was starting to Fall into the inexpensive achieve of network topologies. That trend has continued and now 10Gigabit Ethernet (10GbE) is frequently being used in enterprise data centers. Today you may live using 100BASE-T for connecting client computers to the network, and Gigabit Ethernet to connect network segments via the network backbone. In some cases your network might even live exclusively based on 10GbE.
What does this value to a network administrator today? With 10Gigabit Ethernet, you can employ TCP/IP not only to create a local locality network backbone, but to extend that achieve to a metropolitan locality network. And because TCP/IP is so intertwined with Ethernet, you can achieve an end-to-end MAN link that uses TCP/IP over faster Ethernet connections. Instead of employing more expensive solutions, such as SONET, you can now connect branch offices in the selfsame geographical locality using just TCP/IP.
You may not maintain to worry about installing expensive outfit used by SONET and other typical MAN protocols. Still, for the long haul—for example, between different cities—other protocols such as ATM and Frame Relay will near into play.
For more information about SONET, ATM, and Frame Relay, contemplate Chapter 15, "Dedicated Connections."
