Welcome to Hardening Linux! If you're responsible for protecting computers that run on Linux, then this highly valuable book will show you how. You'll learn about crucial topics like hardening the Linux operating system, securing your files and the security of mail, IMAP/POP, DNS and FTP servers. You will also become familiar with hardening bastion hosts including firewalling using iptables and secure remote access functionality.
This book is complete with checklists and reference-style chapters. And each application-focused chapter may be used as a stand-alone "how to" for that particular application. Furthermore, a selection of additional resources is provided—websites, mailing lists, and other reading suggestions—for you to enhance your knowledge base.
You can buy the book from Amazon.com
