Windows 7 and Security

Volume 9 of the Microsoft Security Intelligence Report is out, and it makes for some pretty interesting reading. Among other things, it talks extensively about botnets – the various “families” of botnets, how they are used, how they work, and how access to them is sold and traded on the black market. Why? Because (quoting from the report), “When we look at that intelligence as a whole, it’s clear that botnets pose one of the most significant threats to system, organizational, and personal security.”

One of the things you’ll find in the report is a discussion of the infection rates of different versions of the Windows Operating System. You may have noticed that every now and then, as part of the critical patches and updates that Microsoft pushes to your PC, there’s something included called the “Malicious Software Removal Tool,” or “MSRT.” Microsoft keeps track of how often the MSRT actually finds malicious software when it runs, and that information is presented here as the number of computers cleaned of bot-related malware per 1,000 executions of the MSRT. Take a look at the following graph, which covers just Q2 of 2010 (click to view larger image):

Infection rate found per 1,000 executions of MSRT

I would like to particularly direct your attention to the fact that the infection rate for Windows XP SP3 is four times the infection rate for Windows 7, and the rate for Windows XP SP2 is five times the Win7 rate.

I understand that, for some people, the issue of upgrading from Windows XP to something else borders on being a religious discussion. But, honestly, if Windows 7 is that much more secure – which it clearly is – isn’t it getting a bit difficult to justify the “you can have my Windows XP when you pry it from my cold, dead fingers” position?

Of course, larger enterprises have some challenges to overcome. As we discussed in our September post about the cost of a Windows 7 migration, Gartner recently reported that, since most organizations weren’t planning to begin their Win7 migrations until 4Q2010, and with PC hardware replacement cycles typically running at four to five years at present, most organizations simply will not be able to complete a Windows 7 migration through the normal PC replacement cycle before Microsoft ends support for XP SP3. There just isn’t enough time left.

But even if there was enough time – why would you not want to move to an Operating System that’s four times more secure as quickly as you possibly can?

As Gartner pointed out, one alternative is to move some users to a “hosted virtual desktop” instead of a new PC. Translation: Making VDI part of your migration strategy can help get you out from behind the eight ball. It can also boost the overall security of your organization. Doesn’t that make it a conversation worth having?
