However, armed with such knowledge, we are still in a much better position than resorting to manual forensics. Grant select,insert,update,delete,create,drop,index,alter,create temporary tables,lock tables on baeldung.* to privileges In that way, audit data sits somewhere between a backup and simple history logs: $ cat /home/user1/.mysql_history Of course, operating system auditing doesn’t directly allow recovery like some databases do – we need the data and means for that. ![]() In fact, the mechanism is more or less identical in terms of data to the logs used to track databases such as mysql: $ cat /var/lib/mysql/audit.log In this way, a trail of records exists, whereby events can be reconstructed. It provides a way to map activity to certain accounts, enabling administrators to trace:Ĭombined with strong security concepts such as encryption-protected authentication and authorization, auditing can ensure almost complete accountability.
