 VISTA or XP Pro?

Stay with XP Pro for at least a year.

For several years, especially since Windows XP Service Pack 2, Microsoft has been tightening security in Windows and Internet Explorer. It's hard to see at times, but I do think they have been making progress. Nevertheless, with a completely new version of Windows (Vista), Microsoft has the opportunity to do some radical things that should help a lot more.

Many of these "new" features have been available in other operating systems or third-party products, but having them standard in Windows makes a difference. I'd like to focus on some of the important ones.

Corporate IT has known for a long time (and if they don't, they're incompetent) how to manage their Windows users with restricted permissions, both on the network and on the local computer. For the average home user it hasn't been hard to set up such accounts, but it's common to run into applications that require greater privileges that are provided on Windows XP for a Limited User.

The problem is changed in Windows Vista first by attitude. The word "Limited" is gone and a "User Account" is now limited. Getting an account with Administrator privileges is now the extraordinary case, but it's not generally going to be necessary. If you do something that requires admin privileges, such changing firewall settings, the system will offer you an opportunity to enter account credentials that have sufficient privileges, such as the Administrator account. So you can run normally as a non-Administrator. This is all called "User Account Protection,".

Another User Account Protection feature is that when programs write to protected areas of the file system and registry, these writes are actually stored in a separate area, maintained per user, called the Virtual Store. This is very similar to what is done on a Terminal Server, and in fact I wonder why the Virtual Store is stored in C:\Virtual Store rather than under each user's Documents and Settings folder as is done on Terminal Server.

Internet Explorer 7 has many new security-related features on Windows Vista and Windows XP, but the most important work only on XP. IE runs, by default, in a crippled mode called Protected Mode. Doing bold and possibly dangerous things will require special permission. It's a special type of User Account Protection for the browser.

Even if it works perfectly, all you need to do is convince users that they really do want to do the things that Windows is warning them could be dangerous. IE7 has plenty of other cool and useful security features, but they also all happen in Windows XP.

A good example of a feature that has been around for a while is NAP (Network Access Protection), which came out, I believe, for Windows Server 2003. It is a set of programs and policies, similar to Cisco's Network Access Control Program and the Zone Labs Integrity product line, that defines security and other requirements for a client before it attaches to a network. The requirements can be that Windows be up to date with specific patches, that anti-virus software be running and up to date, that other programs be installed—just about anything.

The advance in Vista may be as simple as bundling the client components of NAP, but it would be good if this encourages use of it. there yet.

Another feature is that Windows Firewall will finally filter outbound traffic. EFS disk encryption will improve. Windows programs can be profiled so that the system will know what resources (such as TCP ports) they use, and anything else will raise a red flag.

This isn't the first time Microsoft has gotten serious about security, so it would be premature to declare victory against security threats, and Microsoft is plenty circumspect about the future of such things. There is some clever stuff here though, along with a continuation of a several-year trend of locking things down after an orgy of opening insecure services in the late 1990s. If all Windows users were running Vista, the Internet would be a much safer place.
