I almost didn't mention it because it's so common a concern now, but just in case.
Static IP gives attackers a lot more leeway in their attempts to penetrate. Be sure your firewall (from ISP and iptables on CentOS machine) are now appropriate for your situation. With port 80 open, make sure your server stuff is kept up-to-date with security fixes. Make sure all services not needed are disabled. TCP wrappers (hosts.deny and hosts.allow) are up to snuff.
Hi Bill,
Thanks,
Yes, I have a firewall setup and also use denyhosts and fail2ban.
Thanks
HTH
