Windows Vista Security
Design PrinciplesMicrosoft has discussed three key areas of security advancements in Windows Vista. Microsoft believes that with Vista, they can make computing even more reliable and secure. According to Microsoft, the following principles are reflected in the design and development of Windows Vista:
Windows Vista Security [Adapted from SBC: An Introduction to Windows Vista: Part 2]
FirewallWindows XP was the first version of the operating system to include a built-in firewall, which was followed by a much-improved version in XP Service Pack 2. Vista's firewall boasts additional enhancements, such as the capability to automatically stop all inbound traffic to a system unless Windows has been updated with all the latest security patches. In addition, it provides better protection than Windows XP's firewall by monitoring not just inbound traffic but outbound traffic as well. This feature lets it prevent unauthorized applications from sending data from your computer.
User AccountsWhen setting up systems, small businesses often create limited user accounts for many employees in order to prevent them from installing unauthorized software and to minimize access (and potential damage) to the system's configuration. The catch, however, is that some applications simply won't install (or even run) unless the user is logged in using an administrator account.
There are other unpleasant side effects as well, such as the inability to perform benign tasks like adding a printer or modifying non-critical system settings. The solution to this problem in Windows XP is to give users administrative access to their own machines, in spite of the risk that entails, but either scenario can easily result in lots of support calls.
Fortunately, Vista offers more flexibility with its significantly revamped user access rules. A new Standard user account replaces the Limited account and allows employees to perform many routine computer tasks for themselves as well as modify many settings related to their own personal profile.
Data EncryptionBusiness systems often contain all kinds of proprietary and confidential data and, needless to say, when such a system gets lost or stolen a company can find itself in significant competitive or legal jeopardy.
To help safeguard sensitive data Vista builds on the file-encryption capabilities of Windows XP with it's BitLocker feature, which can automatically encrypt the complete contents of a hard drive rather than just selected files and folders. On systems that include a special chip called a Trusted Platform Module (TPM), BitLocker can encrypt an entire system without even changing the way a user logs into the system.
You don't necessarily need new hardware to take advantage of BitLocker since it can also work with non-TPM systems, but in this case requires a USB flash drive (to store encryption keys and passwords) that must be inserted whenever the system starts.
More Secure Browsing In addition to the usability improvements discussed earlier, Internet Explorer 7 in Windows Vista also includes a number of security enhancements. A Protected Mode — which was first seen in Vista's Beta 2 and will not be available in IE 7 on other Windows versions — works in conjunction with Vista's new user account rules to limit a Web site's access to the system, which should prevent malicious sites from hijacking browser settings or copying any files to the system.
Whenever you go to a site, a phishing filter automatically checks it against a database to determine if it may be fraudulently trying to obtain a user's confidential information. Finally, clearing the myriad browser caches has been made less cumbersome, requiring only one click to delete your entire browsing history instead of the three or more required in XP.
