Some good ways to make a honey pot on your computer.
- Make a fake account of course. It shoud be easy to break into, but it should have as few privileges as possible.
- Make ls (or cd) set off alarms all over the place, trace the person who did it, their IP, time of day, reverse DNS lookup, anything you can think of. Maybe ban their subnet if you are just trying to be cautious and not catch people.
- Make root a honeypot account. Make your root account something other than root. It might be hard getting used to not using ls and root but it worth it for hard core security.
