Security Enhanced Linux

A short presentation about the concepts and fundamentals of SELinux.

The security basics of SELinux are described in this document. Type Enforcement (TE), Role-Based Access Control (RBAC), Multi-Level and Multi-Category Security (MLS/MCS) are discussed in a comprehensive way.

Port Management

This little utility helps you to manage your installed ports. For example you could create a cronjob to run on a daily base to check if a port is out'dated. If an event comes up an e-mail will be send.

I use this tool to get around of OpenBSD's management weak points ;-)
