First, you can block all inbound traffic. If you have any services running, then you need to make sure that they are properly secured. If you have anything open to the Internet (like a webserver) you need to make sure that t is properly secured. Even if you have something like Apache properly secured, any applications (e.g., CGI, PHP, etc.) that you have being served by it could be vulnerable. For example, many popular forum and bulletin board packages have many well known vulnerabilities. If you are running things you developed yourself, you need to make sure that you don't have places where a SQL injection can be performed, or where shellcode can be introduced, etc. That is just a small sampling of things that could be possible issues. There are just too many to list them all. Another approach is to wipe the system clean, install it fresh and completely lock it down. Then add applications/services one at a time, making certain that each one is properly configured/secured/etc. Regards, -Roberto -- Roberto C.
