Now !!!
You are in the Internet and some of you use Firewall.
What you know about Firewall?
You think Firewall safe? no! no!
How it works?
it will close all danger ports and allow some ports to connect for example FTP (21), E-mail (23), HTTP (80) etc.
The weak point >>> if someone use anonymous software to connect with port 21, 23 or 80 What will happen?
some case anyone can connect to your PC if you not careful.
The way to know what the ports are Firewall open >>> sent ICMP or RAW of scan and find open port this case Firewall will not block!!! and Jackpot!!! then go through the Firewall.....
We can trust the FIREWALL???
