Breaking in is half the battle. I’ve talked to so many people whose only objective is to try and break into systems. I get that. It’s awesome, the rush you get when you bring up that shell. But what then? Ops hardening does not end at the outer shell. Once you’re in, you still have to navigate the maze of files, directories, and permissions that is the Linux file system. This talk will cover discovering services, combining a simple netcat script with crontab to create access windows, adding users, and selectively deleting logs. Minimal Linux experience needed. If breaking in is half the battle, staying in wins the war.
