Linux.com: Matt Michie's Security Outlook: Part I

Dec 11, 2000, 19:02 (0 Talkback[s])
(Other stories by Matt Michie)

"This series of articles will guide a fledgling Linux system admin through entry level computer security routines. It will consist of basic tutorials on subjects such as where to find Linux security information, what services are vulnerable or have been vulnerable in the past, encryption, firewalls, network intrusion detection systems, and more."

"In this first article, I will outline threats to which a sysadmin should immediately respond. The three basic areas of vulnerability are physical access, local area network access, and remote access."

"Physical access attacks are essentially impossible to defeat strictly using software. If an attacker can physically access your machine, your system can be compromised. For instance, physical attacks may consist of using a simple root boot disk, or even just yanking the hard drive. Physical security depends more on the security of the entire building and the room where the system is located."
