It's not a question of "if" but "when." Will you be ready to protect your system when a cracker comes? Real World Linux Security goes beyond the books that merely detail system vulnerabilities by offering system administrators practical solutions for safeguarding Linux systems and actively responding to break-in attempts. Veteran Bob Toxen shows you how to know your enemies and stop them at the front gate, before they can damage your system. The book is organized into four sections: securing your system, preparing for an intrusion, detecting an intrusion, and recovering from an intrusion. Toxen even provides at-a-glance icons and tables rating the severity and likelihood of each type of attack. Along the way, you'll learn how to configure systems so they alter themselves to lock out a cracker -- and notify the sysadmin immediately -- at the first sign of attack. You'll discover virtually cracker-proof techniques for protecting credit card databases, even if your web server and network are compromised. Toxen also presents techniques for ensuring that, if a break-in does occur, damage will be minimal and a full recovery can happen fast. This fully updated Second Edition now covers IP tables, home, mobile, and wireless issues, and protecting your network from users as well as crackers.
