The following tip is one of six steps to help you protect Windows systems from bi-modal attacks. Click to return to the main page.


Internet Protocol Security (IPsec) won't block all attack vectors. But it can protect critical systems from worms or viruses that may spread within your environment to network shares and other systems on the local area network (LAN). Use it on Windows 2000 or Windows Server 2003 systems to restrict access to those systems.

You can create IPsec policies on the critical servers, which only allow certain types of communication, or only allow communications with known IP addresses or subnets. Attempts from unauthorized systems will be blocked.
