Unpatched Linux systems are surviving longer on the Internet before being compromised, according to a report from the Honeynet Project released this week. The data, from a dozen networks, showed that the average Linux system lasts three months before being compromised, a significant increase from the 72 hours lifespan of a Linux system in 2001. Unpatched Windows systems continue to be compromised more quickly, sometimes within minutes, the Honeynet Project report stated. The results are probably due to two trends, Spitzner said.

Microsoft’s Peter Torr Attacks Mozilla Firefox Security

A Microsoft Program Manager by the name of Peter Torr has posted a weblog entry about potential problems with security in Mozilla Firefox.
