MMORPG Game Security questions

have any idea of how to improve security on my mmorpg (its not out yet)

I dont think MMORPG is a real security threat....

um...lol, here's an idea: beta test it and look through the code alot. make sure the clients cant change anything they shouldnt be able to.
add verification checks for anything even remotely important.

Do you mean something you're buying, or something your developing?
I take it that you mean buying, so you don't really need any security concerns. All you do is send and receive data to a central server, so there isn't any risk of a vulnerability. The only thing I can think of is a game bug that could be exploited to freeze your comp or something like that, or a packet sniffer or sometihng like that to get your PW.

something i'm developing

While not specific it gives good backround of mmog security and concepts.
