For starters ------------ 'tiger' is a set of scripts that scan a Un*x system looking for security problems, in the same fashion as Dan Farmer's COPS. 'tiger' was originally developed to provide a check of UNIX systems on the A&M campus that want to be accessed from off campus (clearance through the packet filter). As such, they needed something that *anyone* could run if they could figure out how to get it down to their machine. If you just want to run it, without regards to time considerations, then just 'cd' into the tiger directory, and run './tiger' as 'root'. The 'tigerrc' file is set up for a generic host, and enables all checks. You can customize this file as needed. (Or use the '-c' switch to use an alternate tigerrc file as of 2.2.2) Please read the file USING for more information on how to use Tiger. And read the file COPYING for legal stuff. If you have any thing to say about 'tiger', please let us know (see below). New things to check, how to improve things, *anything*, send it in... if you think someone else has already sent in a bug report, suggestion, etc., send it in anyway... the more times someone hits us over the head with something, the more likely it is to get fix/included... Needs ----- Tiger needs a standard POSIX shell to run, a C compiler if you wish to compile the binaries used and some other (optional) utilities, including the standard UNIX file utilities and text utilities (the GNU versions work fine for this). Mailing lists ------------- There are now two mailing lists available for the 'tiger' at savannah.gnu.org. These two mailing lists are: - a user's mailing list: tiger-user@nongnu.org Dedicated to users of the Tiger tool, feel free to ask here any questions on how to run the tool, configure it or adapt it to your system. http://lists.nongnu.org/mailman/listinfo/tiger-user - a developer's mailing list: tiger-devel@nongnu.org If you want to help us improve Tiger this is where all discussion on improvements on the tool take place. http://lists.nongnu.org/mailman/listinfo/tiger-devel Note that the previous mailing list (at 'majordomo@net.tamu.edu') does no longer work. Availability ------------- The latest versions of Tiger can be downloaded from Savannah at http://savannah.gnu.org/files/?group=tiger Previous versions are available at the "TAMU Security Tools: Tiger" page http://www.net.tamu.edu/network/tools/tiger.html You can browse the CVS code at http://savannah.nongnu.org/cgi-bin/viewcvs/tiger/tiger/ More information on the project, including bug tracking, task manager, etc. available at: http://savannah.nongnu.org/projects/tiger Latest signatures ----------------- You can check to see if you have the latest digital signatures for the system(s) you are checking. There are some signature files available on anonymous FTP at net.tamu.edu:/pub/security/TAMU/tiger-sigs/* The util/installsigs script can be used to install the updated signatures. As of Tiger 2.2.2, installsigs is also capable of installing signatures for new OS releases (not new platforms or major releases though). Note however, that these signatures have not been updated for quite some time (and might not be up-to-date with your current system). If you can provide newer signatures please submit them to the developer's mailing list. History ------- Tiger was originally developed by the A&M campus of the Texas University, it was written at the same time that COPS, SATAN and Internet Scanner were. Eventually, after the 2.2.4 version, which was released in 1994, development of Tiger stalled. Three different forks evolved after Tiger: TARA (developed by Advanced Research Computing, available at http://www-arc.com/tara), one internally developed by the HP corporation by Bryan Gartner and the last one developed for the Debian GNU/Linux distribution by Javier Fernandez-Sanguino. These forks were merged on may 2002 and in June 2002 the new source code, now labeled as the 3.0 release, was published at the Savannah site. The 3.1 release was distributed in October 2002, it was considered an unstable release and included some new checks, a new autoconf script for automatic configuration, but mostly included fixes from bugs found after testing Tiger in Debian GNU/Linux and in other operating systems. Over 2200 lines of code and documentation were included in this release.
