Linux file auditing to see who made changes

Anonymous Reader writes "This is one of the key questions asked by new admins - How do I audit file events such as read / write etc? How can I use audit to see who changed a file in Linux?

The answer is to use Linux 2.6 kernel’s audit system. Modern Linux kernel (2.6.x) comes with auditd daemon. It’s responsible for writing audit records to the disk. During startup, the rules in /etc/audit.rules are read by this daemon. You can open /etc/audit.rules file and make changes such as setup audit file log location and other option. The default file is good enough to get started with auditd."
