Audit delete commands in Linux
(This article is the essence of a post from this Redhat Archive and it goes as follows:
Problem: You need to detect what deletes files on your Linux
Solution: Using auditd, with the right flags, you could get a lot of information.
- If the mount point/directory is /oracle, then:
- (as root:) auditctl –w /oracle -k whodeletedit -p w
(Explanation: Monitor the directory /oracle, and log everything under the label “whodeleteit”. Monitor write operations)
- To see, later, who deleted files, run (as root): ausearch -i -k whodeletedit -x /bin/rm
- You would want to stop the logging as soon as you found the culprit, by running (as root): auditctl –W /oracle -k whodeletedit -p w
I hope it helps you just as it helps me.
