SANS Resources – The Twenty Most Critical Internet Security Vulnerabilities (Updated). The Experts' Consensus Version 2.100 October 2, 2001
A little over a year ago, the SANS Institute and the National Infrastructure Protection Center (NIPC) released a document summarizing the Ten Most Critical Internet Security Vulnerabilities. Thousands of organizations used that list to prioritize their efforts so they could close the most dangerous holes first. This new list, released on October 1, 2001, updates and expands the Top Ten list. With this new release, we have increased the list to the Top Twenty vulnerabilities, and we have segmented it into three categories: General Vulnerabilities, Windows Vulnerabilities, and Unix Vulnerabilities.
The SANS/FBI Top Twenty list is valuable because the majority of successful attacks on computer systems via the Internet can be traced to exploitation of security flaws on this list. For instance, system compromises in the Solar Sunrise Pentagon hacking incident and the easy and rapid spread of the Code Red and NIMDA worms can be traced to exploitation of unpatched vulnerabilities on this list.
