Never rush into anything, take it easy. Take your time, make sure everything is as secure as possible. Never believe your box is secure: Always believe it isn’t secure, try to find a way to break it (using an exploit), then patch it up.
Here are links to the commonly used software:
- Apache – Web server
- PHP – Web page generator
- MySQL – Database server
- Nmap – Security scanner
- SSH – SSH Secure Shell
- PureFTPd – FTP Server
Remember to check PacketStorm Security for new exploits often.
Searching Google for something like "<software> <version> exploit" will usually list exploits on that software (and that version).. For example: "PureFTPd 1.0.13 exploit".
If anyone needs any help, or can’t figure out how to turn off a service, or anything like that, please go over to the Free2Code Forums.
