I'd make a script that only allows your IP to attempt RCON log ins. Only you should have RCON.

This will only allow you to have access. Just set YOUR_IP_HERE to your IP.

pawn Code:

public OnRconLoginAttempt(ip[], password[], success)
{
    if(strcmp(ip, "YOUR_IP_HERE", true))
    {
        new pip[16];
        foreach(new i: Player)
        {
            GetPlayerIp(i, pip, sizeof(pip));
            if(!strcmp(ip, pip, true))
                Kick(i); //Kick'em out.
        }
    }
    return 1;
}
