Most Configuration tasks have security implications. At the current state of the art, it is probably too difficult for most of us to maintain a completely secure system, so the goal has to be to make the cost to a malicious hacker of penetrating our systems more than the penetration would be worth to him or her.
The following outline focuses on what has to be done and what tools are available rather than why and how to do security configuration, except for the first item, which is meant to focus on getting the user started with security configuration.
- Base System Security
- Configuring and using su and sudo
- Identifying and disabling extraneous services
- chrooting common services and commands
- Basic system logging
- Network Services
- Firewall - Iptables, configuration, firewall software
- Local Policies - Legal Stuff
