Linux Network Security
Security is often an area that system administrators don't have enough time to address. Unfortunately, in today's environment all networks are potential hacker targets, from topsecret military researc networks to small home LANs. Most current Linux documentation focuses more on ease of use than security, so Linux Network Security focuses on securing
Linux in a networked environment, where the security of the entire network needs to be considered, rather than just isolated machines. This complete guide provides a mix of theory and practical techniques to teach administrators how to install and use security applications, as well as how they work and why they are necessary in their networks. Starting with the need for security and understanding the problem, the book teaches administrators about packet filtering (firewalling) with iptables, hardening services such as Apache, BIND, Sendmail, FTP, and MySQL to prevent attacks, network analysis, encryption, local security, DoS attacks, and rootkits. Auditing networks for potential vulnerabilities and creating secure passwords are also explored. This is the one book that really details how to secure a Linux network.
