Other Issues
Important undiscussed (and firewall related) issues in network
security include:
- The importance of logging system activity in tracking break in
attempts, and the use of log files in subsequent court
actions.
- Legal and ethical issues, both from the perspective of the
system manager and in relation to the crooks.
- Passwords -- their general applicability, the tendency of
people to share them around and the sacrosanct nature of
/etc/passwd
- Security within Unix (and other environments), and the use of
tools such as
cops and crack.
- Network security analysis tools, including the notorious
satan.
- The entirely unresolved philosophical and ethical question as
to whether it is nobler to discuss issues like all of these in a
full and frank way, or to hide them and hope the students and other
potential bad guys don't hear about them...
If you are interested, there are various Firewall-related sites on the Web with
much more information than can possibly be provided here.
The tutorial for this lecture is Tutorial
