Port 80 traffic: Sources Increase

Dec 8, 2003 12:43AM PST

The number of sources which scan for port 80 have been increasing. Please take a look at your web logs to check for any unusual activity.

The number of sources scanning a specific port is usually a very sensitive indicator for new self propagating attacks. Given the significant background noise from older worms (Code Red, Nimda, Nachia), it is not easy to spot a new attack.
