FreeBSD and OpenBSD are increasingly gaining traction in educational
institutions, non-profits, and corporations worldwide because they
provide significant security advantages over Linux. Although a lot can
be said for the robustness, clean organization, and stability of the BSD
operating systems, security is one of the main reasons system
administrators use these two platforms.There are plenty of books to help
you get a FreeBSD or OpenBSD system off the ground, and all of them
touch on security to some extent, usually dedicating a chapter to the
subject. But, as security is commonly named as the key concern for
today's system administrators, a single chapter on the subject can't
provide the depth of information you need to keep your systems
secure.FreeBSD and OpenBSD are rife with security "building blocks" that
you can put to use, and Mastering FreeBSD and OpenBSD Security shows
you how. Both operating systems have kernel options and filesystem
features that go well beyond traditional Unix permissions and controls.
This power and flexibility is valuable, but the colossal range of
possibilities need to be tackled one step at a time. This book walks you
through the installation of a hardened operating system, the
installation and configuration of critical services, and ongoing
maintenance of your FreeBSD and OpenBSD systems.Using an
application-specific approach that builds on your existing knowledge,
the book provides sound technical information on FreeBSD and Open-BSD
security with plenty of real-world examples to help you configure and
deploy a secure system. By imparting a solid technical foundation as
well as practical know-how, it enables administrators to push their
server's security to the next level. Even administrators in other
environments--like Linux and Solaris--can find useful paradigms to
emulate.Written by security professionals with two decades of operating
system experience, Mastering FreeBSD and OpenBSD Security features
broad and deep explanations of how how to secure your most critical
systems. Where other books on BSD systems help you achieve
functionality, this book will help you more thoroughly secure your
deployments.
