Apache/Linux Security -- Suggestions?
Can you guys/gals with Apache/Linux tell me what types of security software you have on your servers?
So far as I know, this is what we have on each server ...
Portsentry
/etc/hosts.deny (Deny all for telnet/sshd)
/etc/hosts.allow (Allow access for known customers only)
Built in Background process killer (ircd, egg drop, psyBNC, etc.)
Are there any other programs that might detect a hack and email the administrator? I have heard of such a program, but would like to know if anyone can make a recommendation.
Thanks.
