One simple tip that will improve your forums security greatly.

[Jesus]

Remove RSS feed.

Almost no one uses it anymore, but can easily cause forums to be hacked.

Any forum that I see has rss feed, I am not signing up.

How to remove for forum software:

MyBB:
Remove syndication.php and rss.php and all links to those pages.

PhpBB:
Delete feed.php

Why is RSS a security vurnerability? It's just XML that shows the most recent posts on a forum. 😛 Whebecer security vulnerabilities become known in things like that, the software maker will patch them.

How can this make your site vulnerable exactly? A lot of members on my forum use this and it's pretty common so I don't think I'll want to remove it for that reason. There seems to be no problems like this reported for MyBB, at least.

Considering you're a banned member, I'm not believing you and calling BS on this. 😛
