If we take a look at the history of key threats versus the operating system security enhancementswe can clearly see that both sides have been very active over the last 15 to 20 years. AroundWindows 95 when the internet was just growing we couldnt really speak a lot about security.However with the release of Windows ZP in 2001 we introduced a couple of security features tomitigate some of the key threats. Im sure some of you will still remember the Melissa virus or theLove Letter War which leveraged social engineering or e-mail back then.

Around 2004 when we released XP service pack 2, we introduced our SLR and DEP. SLR standsfor address space layout randomization and is a computer security method which involves randomlyarranging the position of key data areas. And position of libraries in a processors address space.DEP is intended to prevent an application or a service from executing a code from a non executablemember region. This was also at the same time when we had the same time Blaster War andSlammer effect around the world.In 2007 with the release of Windows Vista we introduced Bit Locker for hard disk encryption andPatchcard which is a feature that prevents patching the kernel of the operating system. Other keyfeatures around integrity levels and secure by default configuration for Windows features andInternet Explorer were introduced as well. This was also the time where the script keys were activeand theyre still a potential threat to the industry and their operating systems.With the release of Windows 7 in 2009 we improved our security features by adding biometricservice and enhanced auditing, Windows Defender and many other features, however the threatshave also improved and industry have to deal with Botnets, a botnet is basically a collection ofinternet connected programs communicating with other similar programs in order to performdifferent tasks. The famous Conficker virus was also active around this time and has causedtrouble to many customers around the world.Finally last year in 2012 Microsoft released Windows 8 the most enhanced operating system everfrom Microsoft. The security features that were added are key to the overall stability and reliabilityof the operating system and this course will cover the security enhancements of Windows 8 indepth.

Windows 8 gives you greater control over the software that runs on your PCs. Malware risks aredramatically reduced by eliminating known exploit techniques and making it more difficult to createnew ones. Boot and root kits have literally been designed out of the threat landscape and in theincreasingly unlikely event of a malware intrusion Windows is more capable to detect and remove it.To you as a customer this means improved client up time, reduced support costs and reducedsecurity risks.BitLocker has been our solutions for encrypting confidential data since Vista and Windows 8improves BitLocker by simplifying the provisioning and the compliance management of encrypteddevices on a variety of PC form factors and storage technologies.

And finally, modern users are mobile and their mobility helps them be responsive and productive.However, modern users need modern access controls which Windows 8 provides while increasingdata security within the Enterprise.

There are also some challenges, one of the biggest challenges is with malware it can evencompromise a PC before Windows starts and this has been a challenge in the past evensophisticated anti-malware might not be able to find those.Windows 8 introduced multiple features to address those issues, secure and trusted boot is ourpriority. Also the access to resources are mostly limited to some sort of authentication but notnecessarily to the health or device integrity and Windows 8 addresses those concerns.
