NAME
       twintro - introduction to Tripwire software

DESCRIPTION
       Tripwire 2.3.1 is a file integrity assessment product for Linux net-
       works.  Rather than preventing an intruder or virus from attacking sys-
       tem 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 speci-
       fied 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 soft-
                 ware.  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, con-
                 figuration, 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.
