Linux System Security

This page will include discussions of security measures that can be taken on a linux system to increase, or enhance the overall system security. Right now I don’t have much that I’m placing here, but software that can monitor connections to services and add hosts to the denyhosts file in response to repeated connection failures.

Fail2Ban – this software monitors connection attempts to multiple services and dynamically edits the deny.hosts file in response to failed logins. This way persistent connection attempts are blocked. (Of course, if you’re under attack by a distributed botnet this will by like sticking the finger in the hole in dam, but you’ve got to at least try to make it harder for them somehow.)
