Though the overall number of viruses being detected each month is falling, the severity of the viruses that are being written is increasing, with this year's Code Red and Nimda worms as perfect examples of this trend, according to Vincent Gullotto, senior director of McAfee AVERT Labs, who spoke at Comdex in Las Vegas earlier this month.

There is a high probability that the U.S. critical computer infrastructure, such as the Web site of the U.S. Department of Defense, is being targeted for distributed denial of service attacks by cyberprotestors, according to a warning issued Friday by the National Infrastructure Protection Center (NIPC).

Symantec Corp. last month announced its new Firewall/VPN integrated-security product line, which comes in three models.

A new variant of the Nimda worm has appeared on the Internet, though exactly how it is different or whether it will be more or less serious than the original worm is so far undetermined, antivirus firms said Tuesday.

Denial of Service attacks are still a major threat to the Internet and are becoming more serious as attackers are increasingly creating automated attack tools and focusing on network infrastructure such as routers, according to a new paper released this week by the U.S. government-funded Computer Emergency Response Team/Coordination Center (CERT/CC).

In an effort to help its customers secure their computer systems and maintain that security, Microsoft Corp. this month announced a new program called the Strategic Technology Protection Program (STPP).

A new mass-mailer worm, purporting to provide information about the disease anthrax, has appeared on the Internet, but is being hampered because of a flaw in its design, antivirus companies said Wednesday.
