Computer networks allows access to information and services in an organized as well as controlled manner. Security is needed to make the users' data immune to any kind of data breach or malicious virus attacks. Hardening is to make system hard to protect from unauthorized access and is an on-going process of providing security. As, LAN hardening is done to secure whole organization network from attacks. In this paper, model is proposed for LAN hardening to reduce security risk. LAN hardening is divided into three parts-client/server, hardware and topology hardening. By applying hardening techniques on all parts LAN is harden.
