       twintro - introduction to Tripwire software

DESCRIPTION

       Tripwire 2.4 is a file integrity assessment product for Linux networks.  Rather than
       preventing an intruder or virus from attacking system files, Tripwire detects intrusions
       when they do occur. By comparing system files and directories against a previously stored
       "baseline" database, Tripwire finds any additions, deletions, or changes to specified
       properties.  This allows the system administrator to determine the extent of the problem
       and begin necessary damage control.

       After Tripwire is installed on a system, the following four commands are used:

          tripwire(8) is used for most of the basic operations of the software.  This includes
                 creation of the Tripwire database, and checking the integrity of the filesystem
                 against that database.

          twadmin(8) is used to create, encode, and sign Tripwire policy, configuration, and key
                 files, and for various administrative functions.

          twprint(8) prints Tripwire database and report files in a plain text format.

          siggen(8) is a file utility that displays hash values for files.

       In addition to the command references listed above, the following three man pages provide
       information on important components of the Tripwire package.

          twfiles(5) provides an overview of the various files created and used by Tripwire,
                 including default locations and settings.

          twconfig(4) explains the configuration file, which is used to set system-specific
                 information that affects Tripwire operation.

          twpolicy(4) explains the policy file, which specifies the files and directories
                 Tripwire should check, and how they should be scanned.

       Using the --help flag with any Tripwire command (e.g. tripwire --help) will print a short
       summary of the command modes for that command.  If a mode selector is also specified
       (e.g. tripwire --check --help), a mode-specific usage message will be displayed.  Using
       the all argument with the --help flag (e.g. tripwire --help all) will print detailed usage
       messages for all modes of the specified command.
