Linux Server Security: Hack and Defend

LEVERAGE LINUX STABILITY AND SECURITY FEATURES TO KEEP YOUR SYSTEM SAFE

Linux has become the most popular web server platform on the planet, which puts Linux security measures at the top of the priority list for every sysadmin and every hacker. Linux has always been a hotbed of technology and developments in the security realm, with both offensive and defensive tools like knockd, netcat, Nmap, Nping, and others, but knowing how to exploit these tools the way a hacker would is becoming an increasingly essential part of keeping your system safe. Instead of chasing after the bad guy, learn to anticipate and block his every move.

Chris Binnie is a Linux veteran with server deployment experience in banking and government where security concerns are critical. Chris walks through challenging scenarios in a diverse array of security areas to demonstrate robust detection, prevention, and defensive techniques, providing the hard–won insight of experience every step of the way. These techniques apply across distributions, including Debian and Red Hat derivatives, and other Unix–type systems, and include the expert touches that make software packages work well with the operating system as well as with other packages. Linux enjoys a well–deserved reputation for bedrock stability, which is why it powers up to 70 percent of the Internet′s public servers; this book provides the insight and skill set you need to keep it locked up tight.
