Port Scan

disabling ICMP/ping won't stop anyone from scanning specific ports of your server.

di ba close man ang ports unless imo ispecify na iopen?

well, IPS can also prevent port scanning but it needs some investment.

di ba close man ang ports unless imo ispecify na iopen?

better safe than sorry, do not assume nga close ang port just because wala nimo gi-open explicitly. some programs open ports and firewalls generally warn you that a particular program tries to connect to the internet or accept incoming connections but rarely indicate the port number that it will be waiting for connections.

To check if your a system is really secured you can try this port scanning utility:

Angry IP Scanner.

^ Haven't heard of laws against port scanning since it never really does any damage to any network. Only the things that one does after they scanned an open port, that's where the damage would exist.
