We've been hacked on two separate occasions. I suspect that the first time they got in through Joomla. And I know for sure that they got in through Joomla the second time.
What can we do to secure this installation so these script kiddies can't get in and deface my sites?
I've heard one solution is to block all OUTGOING on PORT 80 using iptables. However this presents me with a problem: The joomla sites have RSS feeds, and RSS won't work if OUTGOING PORT 80 is blocked. Is there a way around this?
ANY Help and tips on security highly appreciated
