Professional Linux Security

Using real-world scenarios, this advanced book provides practical information and unique insight on where specific Linux security pitfalls lurk, how they can be exploited, and how to fix them. Helpful code examples (in C and Perl) such as a rudimentary Ethernet sniffer and writing a custom Bastille module for Bastille Linux are included to serve as highlight ways of assessing and preventing security threats. It offers a solid introduction to cryptography and why it is important for a Linux security administrator to understand it. Also covered are advanced security mechanisms that can be enforced directly by the Linux kernel (MAC/RBAC and memory model protections).
