Is Vista Secure Enough??

    The security system in windows XP was enhanced after the introduction of its service pack 2.Many security systems built into vista are much more secure than XP.
Let me introduce to some of its security features.

User account control (UAC):
Previously in XP users use to set up administrator accounts in order to make changes in the system settings, applications, software updates, etc.., but this is not quite safe ! so Microsoft has come up with UAC in which users have limited capabilities and cannot perform any administrative tasks, for doing so he/she has to authenticate himself by providing a password.

Windows defender:
Vista gives a round – the clock protection by providing integrated anti-spy ware and anti-malware solution that works largely in the background.

Time limits:
With the vista you can set time limits for a particular user i.e. you can block out the time periods during which they can and cannot log on and use the system. This is done via a simple hourly grid system which is very easy to set up.

Games:
Vista integrates with the ESRB game ratings to help you allow and block all games based on their content. Or, you can choose to block all games automatically or set up white and black lists of allowed and blocked games.

USB device lockdown:
One of the good security enhancement in vista is that it can prevent users from connecting they USB mass storage device like an external hard drive, pen drive, etc.
This feature is basically targeted towards businesses to ensure confidentiality of data.

Patch guard:
All newer processors by Intel as well as AMD provide a hardware based security feature on the processor itself- known as the NX bit. Vista has taken the advantage of this feature by including the kernel patch protection also called the patch guard, which prevents alternations to the vista kernel at runtime.
