- Texas A&M Network Security Package Overview
- BETA Release 1.0 -- 4/16/93

- DESCRIPTION:
-
- Last August, Texas A&M University UNIX computers came under extensive
- attack from a coordinated group of internet crackers. This package of
- security tools represents the results of over seven months of development
- and testing of the software we have been using to protect our estimated
- twelve thousand internet connected devices. This package includes
- three coordinated sets of tools: "drawbridge", an exceptionally powerful
- bridging filter package; "tiger", a set of convenient yet thorough
- machine checking programs; and "netlog", a set of intrusion detection
- network monitoring programs. While these programs have undergone
- extensive testing and modification in use here, we consider this to
- be a beta test release, as they have not had external review, and
- the documentation is still very preliminary.
-
