Absolute BSD focuses on FreeBSD's features, benefits, and strengths - specifically on using BSD systems as high-performance Internet servers. Designed for new system administrators with basic UNIX knowledge who want to accomplish essential tasks with the FreeBSD operating system, the book's main focus is on FreeBSD, but much of its information is also applicable to OpenBSD and NetBSD. BSD-specific features are covered, such as how to build a high-performance server, secure it, prepare crash dumps, and interoperate with other network servers. A troubleshooting section that addresses problems that a new FreeBSD administrator might encounter is also included.
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 FreeBSD.
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.
