Abstract
Texas A&M University (TAMU) UNIX computers came under coordinated
attack in August 1992 from an organized group of internet
crackers. This package of security tools represents the results of
over seven months of development and testing of the software currently
being used to protect the estimated 12,000 networked devices at TAMU
(of which roughly 5,000 are IP devices). This package includes three
related sets of tools: "drawbridge," a powerful bridging filter
package; "tiger," a set of easy to use yet thorough machine checking
programs; and "netlog," a set of intrusion detection network
monitoring programs.
