I've been getting a bit more paranoid lately, after hearing
many tales of boxen sitting on cable modems and others on perm
connections getting hacked into.
1. Enter Nessus (http://www.nessus.org/) ... install it, attack
your machines and bask in the glow.
QUESTION: how complete do SLUGGERS feel Nessus' attacks are?
Can such a tool give one a false sense of security?
2. More effort: hide all your boxen behind NAT and use a firewall.
3. As Peter Mc mentioned: the prime directive is to disable as
many ports of entry as possible - this is your first line of defence.
4. Use security tools like a portscan logger and change detection like
tripwire.
5. Watch your logs daily.
6 - 10. There is no 6. 10. is noop().
Eternal vigilance is the price of a healthy network.
