Which software is most secure for web-based webhosting?
I'm trying to set up a webhost account for my friend on my own connection, and I'm running the default install of OpenBSD 5.0 with -stable patches.
So far I'm probably going to install PHP/MySQL because my friend wants to run a forum.
I know how to run my own webserver, but I don't know how to make it usable for someone else, while keeping the system secure. He doesn't know what SSH is, so I need to make the hosting all web interface, logging into my own site and setting up all his website stuff there, etc.
Which software would be best to run on my webserver that is user-friendly but is also the most secure?
