NAME
twintro - introduction to Tripwire software
DESCRIPTION
Tripwire 2.3.1 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.
