More than 600 new Internet security vulnerabilities were discovered during the first quarter of 2005, according to the SANS Institute and a team of experts from industry and government. The new report released today ( identifies the most critical vulnerabilities disclosed in Q1 that pose critical risks to help organizations prioritize patching and other defensive actions. Individuals and organizations that do not correct these problems face a heightened threat that hackers will take control of their computers and use them for illegal activity.

“These critical vulnerabilities are widespread and many of them are being exploited right now,” according to Alan Paller, director of research for the SANS Institute. “We’re publishing this list as a red flag for individuals and IT departments who may be unaware of these vulnerabilities, or mistakenly believe their computers are protected.”

Gerhard Eschelbeck, chief technology officer of Qualys and author of the “Laws of Vulnerabilities,” along with other experts in the community, provided contributions to the development of the SANS Top 20 list.

“The SANS Top 20 list is a widely recognized benchmark for identifying the most critical security vulnerabilities,” said Gerhard Eschelbeck, CTO and VP of Engineering at Qualys. “Threats are evolving at a much faster rate, necessitating regular updates to the list to ensure organizations have the most current information possible on critical security vulnerabilities.”

In addition to providing a free scan, Qualys has updated its QualysGuard® vulnerability management platform to detect the SANS Top 20. Qualy’ on demand model provides customers with immediate vulnerability updates, such as the Top 20 listing, without the need for installing software or building out additional infrastructure.
