Model Keamanan Jaringan Menggunakan Firewall Port Blocking

Abstract

Security is a very important element in computer networks. This is done in an effort which provide protection to the computer network preventing threats from both internal and external in an effort to prevent forced (illegal) data retrieval. A network security system needs to be built to control access to important assets, which is called data, so that access rights for each computer and user need to be regulated. The port blocking method is one of the techniques that can be used to regulate access from users and computers. Port blocking can be used to set network permissions on each LAN port (Local Area Network). Specifically, different port settings with the default method or static port security, dynamic learning port security and sticky port security can be done. This is very useful for blocking access from one party to another to prevent data theft from unknown and known people. From the tests carried out, sticky port security can run well according to the given performance.
