Though rootkits have a fairly negative image, they can be used for both good and evil. Designing BSD
Rootkits arms you with the knowledge you need to write offensive rootkits, to defend against malicious ones, and to explore the FreeBSD
kernel and operating system in the process.
Organized as a tutorial, Designing BSD
Rootkits will teach you the fundamentals of programming
and developing rootkits under the FreeBSD
operating system. Author Joseph Kong's goal is to make you smarter, not to teach you how to write exploits or launch attacks. You'll learn how to maintain root access
long after gaining access
to a computer and how to hack
Kongs liberal use of examples assumes no prior kernel-hacking experience but doesn't water down the information. All code is thoroughly described and analyzed, and each chapter contains at least one real-world application.
