Microsoft claims that Windows 7 is the safest operating system it has ever built. Is this a mere puff or is there some substance to the claim? In fact there are some strong security features incorporated into Windows 7 which can make a big difference.
1. The core kernel of the Windows 7 operating system has been enhanced and strengthened. Specifically two techniques, Space Layer Randomisation and Data Execution Prevention are very effective at preventing virus attacks at a low level and result in a stronger computing environment.
2. User Account Control (UAC) has been improved. UAC prompts consist of a dialog box seeking users’ permission to continue or stop whenever an important system-level change is about to be made. In Windows Vista the feature became unpopular because of the frequency of the prompts. This led many users to turn UAC off altogether and thus it lost its potential as a security enhancer. Now in Windows 7 the user can taylor the level of alerts to suit thier own tastes and strike a balance between staying secure and useability.
3. Windows 7 comes with Internet Explorer 8. The headline feature here is ‘protected mode’. This relies on various security features of Windows 7 to prevent malicious code from running in the browser.
4. The Windows Security Center has been replaced with the security section of the new ‘Action Center’. This provides quick information regarding the status of important security components on your PC: firewall, spyware, and virus protection. It also keeps you up to date on the status of Windows Updates, Internet security settings, and UAC settings. All the basics you need to know really.
Has Microsoft made a more secure opertaing system? Windows 7 does improve the security of PCs with better controls and protections out of the box and upgraders can look forward to a number of important security enhancements.
