Attempted breakin to my system

ELPDave · 03-07-2007, 07:37 AM

I'm running FC3 on a Dell Dimension 2400

I use Sendmail 8.13.3

Spammers tried to get into my system through ipop3d service

What changes can I make to the Iptables firewall to prevent this ?

Nothing showed up on port 110 on iptables report

Thanks

Make sure all your software (that includes Sendmail) is completely patched. Then use iptables to block out all the IP's except those that need legitimate pop3d access. Dont leave it open to any.

If you search on this forum itself you'll find loads of best practices for hardening a system so I wont repeat myself too much
