Systems and Networks Attack Center

Overview
Internet worms impact Internet security around the world even though there are many defenses to prevent the damage they inflict.

The National Security Agency (NSA) Systems and Network Attack Center (SNAC) publishes in-depth configuration guides to protect networks from intrusion. The NSA SNAC guides also provided protection by changing default permissions and passwords some worms and exploits use to exploit the computer as well as removed extraneous packages that could have undiscovered exploits.
