1)if you build your files from the source they are no backdoored, if you download them compiled forget it. 2)install a firewall and try leave only l2 related ports open 7777 bla bla 3)the most important you add in java protections(if there is no any)like floodprotectors and anti-hack programms codes....if you cannot you buy pack with them, from developer with high reputation 4) finaly if  yur server is about to have over 300 people you go in lameguard web page and order lameguard protection its expensive and is only if you have people on to donate for server survival....
