SPykids is a known defacer of Web Site. How does one prevent them

Find out how they're getting in, and lock that down.

This has happened 2x so far. You need to learn how they are getting in, what measures you can do to block it and such. First, put the web server behind a dedicated firewall, not a NAT box, a firewall - only allow real HTTP or HTTPS sessions to it. Require users to have strong passwords, look it up if you don't know what that means. Block IP networks that don't need access to your web sites - as an example I block about 50 subnets in countries outside of our own and it cuts down on a lot of attempts. -- spam999free@rrohio.com remove 999 in order to email me |

What do I need to add? Only install services that Apache needs and keep both your OpenBSD and Apache fully patched at all times. If you do that, you won't even need a firewall. But if the firewall is based on another computer, it doesn't hurt much (iow, even a firewall can have its buffer overflows and other stuff).. Then there is 0-day exploits. Not much you can do about them I am afraid.. Also, change your passwords after a fresh install. And make them unquessable (like not using the pw 'God' for your 'root' account).

What do I need to add? I don't use that combination, so I can't specifically state what you need to use, but, I have to ask: 1) Is the firewall and web server the same machine? If so, bad idea, firewall should be a stripped down machine with minimal services and only the firewall application. 2) Did you secure Apache and the OS on the machine you use? 3) Does your site require user authentication? I'm in the US and don't do business with foreign companies or need to provide access to our services from foreign hosts, so I block many subnets that seem to target our public IP addresses, here is my short list, it may not work for you. 12.144.182.0/24 12.45.203.0/24 12.98.139.0/24 155.48.106.0/24 168.126.0.0/16 172.184.111.203 193.251.0.0/16 193.252.0.0/16 193.253.0.0/16 195.174.0.0/16 195.175.16.0/20 195.58.124.0/24 200.30.203.0/24 202.88.186.0/24 203.152.22.0/24 205.251.79.0/24 210.173.37.0/24 210.201.153.0/24 210.71.115.0/24 211.54.40.0/25 212.150.124.0/24 212.18.57.0/24 212.202.178.0/24 212.27.32.0-212.27.63.255 212.64.192.0-212.64.203.255 212.64.223.160/29 212.64.223.168/29 212.9.7.0/24 213.13.26.0/24 213.144.176.0/24 213.190.213.0/24 213.228.7.0/24 213.228.8.0/24 216.184.97.0/24 216.76.35.0/24 217.118.224.0/24 217.118.225.0/24 217.118.239.0/24 217.160.110.0/24 218.164.28.0/24 218.252.74.0/24 218.67.128.0-218.69.255.255 218.69.108.0/24 218.69.148.0/24 218.76.98.0/24 219.212.4.0/24 -- spam999free@rrohio.com remove 999 in order to email me |
