Hello
the question is not specifically regaridng cpanel more than securing the linux box that runs the cpanel


the problem is that anybody using packet editing program can edit the packets going to to the server applications and programs


all i need to know are there any methods to block poeple from sending packets using these packet editors and playing with the security of the web applications installed on the servers
specially java applets , online flash gamed , etc.....

i heard there could be some tcp/ip rules , proxifyings or a solutions for this
i hope that somebody can help me

The best way to do that would be to use a secure connection if you're worried about such things, i.e. connect over SSL for protocols that support it, and only ever use SSH when connecting to shell. Otherwise, there's little to stop man-in-the-middle attacks on clear text data.
