Firewall, how secure is it?

Hi I have just installed SuSE linux 7.1 default installation with office. I have done the online automatic update and all security patches have been applied. Also i have activated the personal firewall and i set it up to reject all incoming requests. I was wondering though whether is this enough or is there more to be done so that my system can't be compromised Thanks Marios _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
