Hello! I've searched on the forum and not found much about this - apologies if it has been discussed elsewhere. I hope to someday soon be a contributor rather than just a "requester," but as someone just starting out, that might take a little while. Two questions... We are getting a fair amount of attempted hacks and I'd like to make sure we're protected as well as we can be. There are only 3 people who need access to our server with the exception of occasional freelancers. We've enabled CP Hulk and are manually blacklisting every IP with more than 10 denied attempts per day. We have whitelisted the 6-10 IP's that that need access to the innards of our server. 1) Is there a firewall we should be using besides CP Hulk? I was hoping to have CP Hulk permanently ban the IP of all attempted hackers via the option to automagically blacklist them, but can't - because - The system disabled firewall options. These options require IPTables v1.4 or higher and a non-Virtuozzo environment. 2) What exactly does blacklisting prevent? I.e. If I blacklist entire regions of the world, will people in those regions that aren't hackers still be able to email us and visit our website - or are they blocked from every sort of communication? Thank you for your advice and help!
