Securing Your System: Overview

• Securing any unix system is a complicated (possibly impossible) task.
• Attacks can originate from outside or inside of your system.
• Outside problems:
  • Sniffing (in detail) See: http://web.mit.edu/telnet/www/scenarios.html
  • Denial of Service attacks (briefly)
• Inside problems:
  • SUID programs with bugs
  • Incorrectly set permissions

Gosh that's horrible! What's the solution!
