Where i am?

Im an enthusiatic in cyber security related issues.Im a L board H4ck3r.Huhhhh.... Linux is my tools box.Using linux, im always exploring the security flows on Operating Systems.Yes, lots and lots of security analysing softwares are there at free of cost. Basically im interested in networks and protocols. So i always want to scan any host and find out the security issues behind that system. Very Very interesting. I expored some ports are open in some cases. There may be some reason behind that. Yes, some times i need to share my resources within my intranet i will use NetBios protocol to share the system resources. Basically any system connected to the internet is open for all of the world. So we have to put proper firewall to protect our system. For that purpose linux is a proper operating system. Because it has Built-in Firewall called IP Tables with its Kernel. So you are on complete protection.In windows like systems, They does not have thier own firewall. Third party softwares, does not work well with windows operating system. Because they won't give their source code to other people. So linux is a best operating system for internet.
