Publisher review:Nabou is a system integrity monitor. Nabou is a system integrity monitor. That means, it runs every night and watches for changes on files.
If a file has changed in any way, it will inform you by email(if you prefer that). Beside of this it can also look for changed or added user accounts, cronjobs, weird processes and suid files. And you can define your own checks using inline scriptlets.
It stores the properties for each file in a dbm database and will warn you if something has been changed on a file. The most important thing to check for, is the MD5-checksum.
This checksum will never be the same if the file content has changed even if only one letter has changed. But you can also look for some other properties, like ownership or filemode.
