Computer security policies are the basic guidelines and rules for accessing a network. Computer network security is a complicated area, and is taken up by experts with many years of on-the-job experience. The need for general users to understand the concepts of network security has become important.

Network security starts from authenticating the user, commonly with a username and a password. Since this requires just one thing besides the user name, i.e. the password which is something you ‘know’, this is sometimes termed one factor authentication.
Once authenticated, a firewall enforces access policies such as what services are allowed to be accessed by the network users. Though effective to prevent unauthorized access, this component may fail to check potentially harmful content such as computer worms or Trojans being transmitted over the network.
Anti-virus software or an intrusion prevention system (IPS) helps detect and inhibit the action of such malware.
A firewall prevents access to an internal system from the outside the company via the internet on any open ports. A firewall will also prevent internal network users from accessing certain internet sites which could be dangerous or offensive.
Implementation of Network Security
Network security and Wireless Network Security measures are not limited to installation of up-to-date anti-virus and anti-spyware, anti-adware, properly configured state-of-the-art firewalls, intrusion prevention systems and virtual private networks (VPN’s), to ensure secure remote access.
