In particular, add + important directories and files which you would like to be + covered by integrity checks.

Alternatively, keep MD5 fingerprints or GPG signatures + of those files in a secure location, so you have means to verify + that nobody modified those files. + +4) Copy /var/lib/aide/aide.db.new.gz to /var/lib/aide/aide.db.gz + which is the location of the input database. + +5) Run "/usr/sbin/aide --check" to check your system for inconsistencies + compared with the AIDE database. Prior to running a check manually, + ensure that the AIDE binary and database have not been modified + without your knowledge. + + Caution! + + With the default setup, an AIDE check is not run periodically as a + cron job. It cannot be guaranteed that the AIDE binaries, config + file and database are intact. It is not recommended that you run + automated AIDE checks without verifying AIDE yourself frequently. + In addition to that, AIDE does not implement any password or + encryption protection for its own files. + + It is up to you how to put a file integrity checker to good effect + and how to set up automated checks if you think it adds a level of + safety (e.g. detecting failed/incomplete compromises or unauthorized + modification of special files). On a compromised system, the + intruder could disable the automated check. Or he could replace the + AIDE binary, config file and database easily when they are not + located on read-only media. + |
