Defending Against Worm Wave Tough Task: Page 5 of 6

Other best practices that can help during security stresses -- as well as those weeks when worms aren't so prominent on the Net and in the news -- said Symantec's Foster, is to turn off unnecessary file sharing (some of the recent worms can also spread via network sharing) and isolate ASAP any machines infected.

But during weeks like this one, everyone's feeling the stress, which leads to a bit of a blame game.

"It's overwhelming anti-virus companies," said iDefense's Dunham. "They have to find signatures that work and roll them out and then the client has to roll the signatures throughout the organization. That whole process takes time," which is in short supply when a worm blitz strikes.

Sophos' Belthoff conceded that time is tight. "Hackers innovate to disburse their code, and we adapt to detect their new tricks. This is an escalated war, and yes, the reaction time is shortened substantially."

"We need to somehow embrace other techniques," retorted Dunham. "Perhaps a quick signature for network-exposed servers, such as e-mail servers. Something that companies can apply manually if necessary, a quick work-around that will work in a pinch."
