The best protection against such as Blaster is to keep your Windows system updated with all the latest updates and patches.

170697 2003-08-26 09:24:00 As I understand it there are two types of firewall:
1. Application firewalls like Zonealarm - they block applications from accessing your system.
2. packet filters - they block ports on your PC.

The second are more likely to stop worms. All Linux based firewalls I have seen are packet based to block or open services in /etc/services. All ports that do not have a defined function shold be blocked.

If you go to:
network and dialup connections ->properties -> advanced -> options -> TCP/IP filtering in Windows 2000 you can block ports but it doesn't seem to allow you to choose individual interfaces.

170699 2003-08-28 02:00:00 zonealarm will stop intrusion luckily i also am still using 98SE which is immune to the flaws that the recent worms exploit kiwibeat (304)
170700 2003-08-28 11:52:00 From my (limited) understanding firewalls like Zonealarm stop access to all ports on your computer ,and can make them undetectable, EXCEPT those sites that you REQUEST data from. On the other side of the wall, only those applications that have your permission may connect through the barrier. Any program without you permission must get your authority to proceed. This is how to stop the spread of "nasties".that you may have picked up and the loss of data.

This is like saying, invited guests only, and nobody leaves without ID. E-mail is different because you invite it in and it comes through the firewall, because you requested it(logged on to your e-mail a/c). It may be carrying "nasties", this is where your anti-virus comes in. (personal body search of invited guests). The AV also checks other data as it comes in as well.

The latest scare exploited a vulnerability in the operating system of XP and W2000. If you had a firewall this would have "bounced" because the firewall had stopped access to port 135 because you had not told it you had requested data at that port. The patches repair the system behind the firewall .
