Windows 7 Guide- Changes To Security in Windows 7


Microsoft launched Windows 7 with few enhancements such as HomeGroup, Aero, etc. However, there are several of new and enhanced security features as well. Here’s a rundown of key changes you must know about.

Everyone’s talking about the interface changes, the new taskbar, omission of the sidebar, a new look for Windows Explorer. Under the hood, there are few more changes, including latest and enhanced security features. Let’s look at some security features that have been changed or added in Windows 7.
Action Center- In Vista, security configurations can be access from the Security Center in Control Panel. In Windows 7, you won’t find a Security Center. That’s because it’s been replaced by a new Action Center. The Action Center offers security configurations as well as options for other administrative tasks, such as Backup, Troubleshooting And Diagnostics, and Windows Update.

Windows 7 UAC- User Account Control (UAC) was introduced with Vista, made to provide better protection from malware. It makes all user accounts run as standard users, even administrator accounts. If you need to perform something that requires administrative rights, it asks for permission. And asks. And asks. This in-your-face aspect of UAC has caused numerous complaints and has led some users to turn it off completely, thus exposing themselves to threats.
In Windows 7, UAC is still there, but now you can set up how vocal it will be. There are four settings you configure from the UAC settings in the Action Center. You can set UAC to:
• Always notify you when you install software or make any changes to Windows settings (as Vista does now).

• Notify you when programs make changes but not if you make changes to Windows settings (default Setting).

• Notify you only when programs make changes but turn off Secure Desktop, which dims the desktop while the UAC prompt is displayed. ( Preferred setting.)

• Never notify you. ( Not recommended.)
BitLocker- Windows 7 comes through and allows you to encrypt removable storage drives. And it’s easy to do. Just open the BitLocker applet in Control Panel, choose the drive you want to encrypt, and click Turn On BitLocker.

Windows Filtering Platform- Windows Filtering Platform (WFP) is a set of APIs introduced in Vista. In Windows 7, developers can use it to iinclude some parts of the Windows Firewall into their own programs. This will allow a third-party program to turn off certain parts of the Windows Firewall selectively if need be.

DNSSec- Windows 7 supports for DNSSec (Domain Name System Security), which is a group of extensions to the DNS platform that improved security. With DNSSec, a DNS zone can take advantage of digital signature technology so that you can validate the authenticity of data that’s received.
