Posted in Guide, Security, Windows Vista | July 15th, 2008

Microsoft Windows XP is still preferred operating system, instead of the fact that it has a number of security loop holes. When Microsoft started building Vista, there primary goal is to make an operating that can address most of security issues that are addressed in Windows XP. Windows Vista comes with a number of security improvements. It’s important for end user to understand how to use these new security features.

Network Access Protection (NAP): Network Access Protection (NAP) is one of the most desired and highly anticipated features of Windows Server 2008. NAP is a new platform and solution that controls access to network resources based on a client computer’s identity and compliance with corporate governance policy. NAP allows network administrators to define granular levels of network access based on who a client is, the groups to which the client belongs, and the degree to which that client is compliant with corporate governance policy. If a client is not compliant, NAP provides a mechanism to automatically bring the client back into compliance and then dynamically increase its level of network access. Network Access Protection is complicated to setup but I think it’s a good idea to setup Network Access Protection. Step by step guide: How to Set up Network Access Protection.
Turn on Phishing Filter: Make sure that Phishing Filter is turned on for all your desktop computers. The Phishing Filter combines a local (client side) system scanning for suspicious website characteristics with an online service. Phishing Filter checks website characteristics to common Phishing websites, warn if it finds any fraudulent and legitimate website.
The Phishing Filter is not enabled by default—you must actively enable the feature the first time you use the browser after installation. You can enable and disable the Phishing Filter with just a single click at any time using the browser menus.
Use Network Profiles: Windows Vista does not treat all network connections equally as compare to previous version of Windows operating system. Vista’s Network and Sharing center designate a networks as public, private or a domain network. Vista treats domain networks automatically when computer is used to login into a domain. It’s very important to select proper network network profile because vista implements various security features based on network type.
Use Vista 64-Bit Version: Windows Vista’s 64-Bit version is more secure as compare to 32-Bit version. Vista 64bit version offers Data Execution Prevention feature. DEP is a security feature that can help prevent damage to your computer from viruses and other security threats. DEP can help protect your computer by monitoring programs to make sure they use system memory safely. If a program tries running (also known as executing) code from memory in an incorrect way, DEP closes the program.
