? 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 serve to highlight ways of assessing and preventing security threats


? 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)
