NAME
integrit - file integrity verification system This manpage is a brief reference and may be out of date. The definitive texinfo documentation should be viewable by running "info integrit". SYNOPSIS
integrit -C conffile OPTIONS integrit -V integrit -h OPTIONS
-C Specify conffile as the configuration file for integrit. -V Show integrit version information and exit. -h Show brief help. -x Produce XML output. -u Do update - create a new database that reflects the current state of the system. -c Do check - compare the current state of the system to a database containing a snapshot of the system when it was in a known state. -N Manually override specification of the current ("New") database. Normally it is set in the configuration file. -O Manually override specification of the known ("Old") database. Normally it is set in the configuration file. -q Lower integrit's level of verbosity. -v Increase integrit's level of verbosity. DESCRIPTION
The integrit system detects intrusion by detecting when trusted files have been altered. By creating an integrit database (update mode) that is a snapshot of a host system in a known state, the host's files can later be verified as unaltered by running integrit in check mode to compare current state to the recorded known state. integrit can do a check and an update simultaneously.
