DESCRIPTION

   Database Initialization Mode
       Running tripwire in Database Initialization mode is typically one of the first steps in
       setting up Tripwire for regular operation.  This mode creates a baseline database in the
       location specified by the DBFILE variable in the Tripwire configuration file.  The
       database is essentially a snapshot of the objects residing on the system.  During later
       Tripwire integrity checks, this database serves as the basis for comparison.

       When run in Database Initialization mode, tripwire reads the policy file, generates a
       database based on its contents, and then cryptographically signs the resulting database.
       Options can be entered on the command line to specify which policy, configuration, and key
       files are used to create the database.  The filename for the database can be specified as
       well.  If no options are specified, the default values from the current configuration file
       are used.

   Integrity Checking Mode
       After building the Tripwire database, the next step is typically to run tripwire in
       Integrity Checking mode.  This mode scans the system for violations, as specified in the
       policy file.  Using the policy file rules, Tripwire will compare the state of the current
       file system against the initial baseline database.  An integrity checking report is
       printed to stdout and is saved in the location specified by the REPORTFILE setting in the
       Tripwire configuration file.

       The generated report describes each policy file violation in detail, depending on whether
       the specified file system object was added, deleted, or changed.  Each report item lists
       the properties of the object as it currently resides on the file system, and, if
       appropriate, the old value stored in the database.  If there are differences between the
       database and the current system, the administrator can either fix the problem by replacing
       the current file with the correct file (e.g., an intruder replaced /bin/login), or update
       the database to reflect the new file (e.g., a fellow system administrator installed a new
       version of /usr/local/bin/emacs).  The (-I or --interactive) option launches an editor
       that allows the user to update the database quickly.  The Database Update mode of tripwire
       can also be used.

   Database Update Mode
       Running tripwire in Database Update mode allows any differences between the database and
       the current system to be reconciled.  This will prevent the violation from showing up in
       future reports.  If the reported change is unexpected and potentially malicious, then the
       changed file should be replaced with the original version.  If there is a valid reason for
       the change, the database must be changed to match the current files.

       In Database Update mode, the items to be changed are specified in a "ballot box" in the
       plain text report that is launched in an editor program.  The entries to be updated are
       specified by leaving the "x" next to each policy violation.  After the user exits the
       editor and provides the correct local passphrase, tripwire will update the database.
       Options to control this operation include the (-Z or --secure-mode) and
       (-a or --accept-all) flags.

   Policy Update Mode
       Policy update mode is used by tripwire to change or update the policy file and to
       synchronize an earlier database with new policy file information.  The filename of the new
       clear text version of the policy file is specified on the command line.  The new policy
       file is compared to the existing version, and the database is updated according to the new
       policy rules.  Any changes in the database since the last integrity check will be detected
       and reported.  How these violations are interpreted depends on the security mode specified
       with the (-Z or --secure-mode) option.  In high security mode (the default), Tripwire will
       print a list of violations and exit without making changes to the database.  In low
       security mode, the violations are still reported, but changes to the database are made
       automatically.

       Because the policy and database files are binary-encoded and cryptographically signed, the
       user will be prompted for the site and local passphrases to change the policy settings.
       After the database is successfully updated, the database and policy files are re-encoded
       and signed.

   Test Mode
       Test mode is used to check the operation of the Tripwire email notification system. When
       run in this mode, Tripwire will use the email notification settings specified in the
       configuration file to send a test email message. If MAILMETHOD is set to SMTP, the
       SMTPHOST and SMTPPORT values will be used to send email.  If MAILMETHOD is set to
       SENDMAIL, the MAILPROGRAM value will be used.  If email notification is working correctly,
       the address specified on the command line will receive the following message:

            To: user@domain.com
            From: user <user@domain.com>
            Subject: Test email message from Tripwire

            If you receive this message, email notification
            from Tripwire is working correctly.

       Test mode only tests email notification for the address specified on the command-line, and
       does not check for errors in the syntax used with the emailto attribute in the policy
       file.

              High:  In high security mode, if a file does not match the properties in the report
              file, Tripwire reports the differences as warnings, and exits without changing the
              database.

              Low:  In low security mode, inconsistencies are reported as warnings, but the
              changes are still made to the database.

       -s, --silent, --quiet
              Silent output mode.  Mutually exclusive with (-v).

       -c cfgfile, --cfgfile cfgfile
              Use the specified configuration file.

       -p polfile, --polfile polfile
              Write the specified policy file.

              Specifies passphrase to be used with site key to sign the new policy file.

       -Z { low | high }, --secure-mode { low | high }
              Specifies the security level, which affects how certain conditions are handled when
              the existing filesystem does not match the database information.  Since the
              database produced at the end of a policy update becomes the baseline for future
              integrity checks, this consistency-checking ensures that no substantive filesystem
              changes have occurred since the last integrity check.

              High:  In high security mode, if a file on the filesystem does not match the
              properties in the database file, Tripwire reports the differences as warnings, and
              exits without changing the database or the policy file.

              Low:  In low security mode, inconsistencies are reported as warnings, but the
              changes are still made to the database and policy file.

       policyfile.txt
              Specifies the text policy file that will become the new policy file.
