AT&T Wednesday turned on a 24-hour security news service that streams to customers of the carrier's Internet Protect service.

The always-on Webcast includes regular programming that is interrupted by security alerts that AT&T deems important enough to let customers know about right away.

"We're building a security geek channel," said AT&T CSO Ed Amoroso during his keynote address at Interop New York, during which he announced the service.

Programming includes lectures on technologies, interviews with corporate CIOs as well as twice-daily news updates.

The alerts will call attention to worms and viruses and suggest ways to deal with them, Amoroso says. These supplement the existing alerts that AT&T would send along as part of Internet Connect.

Amoroso acknowledged that most threats come from inside corporate networks, and he characterized badly written software as the biggest threat to network security, but he said AT&T's service could help deal with threats coming from outside.
