In the aftermath of last week's malware attacks, many administrators are trying to figure out how their enterprise Windows networks could have been infected. A common factor in many of the infections was the mobility of enterprise laptops. Do you know where your users take corporate laptops when they leave the office? And, do you know what they are bringing back into the office?
It reminds me of Alien. In the movie, the spaceship dispatches someone to the unknown planet. Upon his return to the ship, that someone unknowingly brings something sinister back with him and the survivors are left to deal with the problem. Actually, that basic plot could refer to any number of sci-fi cinemas -- The Thing comes to mind as well.
So how do the space explorers keep from becoming infected (other than not taking a closer look at the pulsating pod)? They outfit themselves in better protective suits.
The protective suit for corporate laptop security is a personal firewall.
Then again, installing and configuring a personal firewall on all corporate laptops can be quite a task -- depending on which firewall you choose.
Windows XP SP2 does come with a personal firewall but, as demonstrated by this latest exploit against Windows 2000, that does not provide much solace for the administrators dealing with the latest infection. Plus, though many consider the Windows XP firewall better than nothing, it is far from highly recommended. Among the chief complaints: It does not block outgoing ports.
