A network security policy outlines rules and regulations for computer use and network access, providing information and security while regulating communication between the network and the internet. It also establishes rules for employee behavior and outlines computer security practices for all network users. The policy takes into account threats from outside and inside and is only as good as its implementation.
A network security policy is a strategic document that specifies the rules and regulations of computer use and computer network access for an organization. Common among government groups, educational institutions, and businesses, a network security policy is usually compiled by policy makers or lawyers. The purpose of the policy is to provide information and computer security and outline user accountability and responsibility. The policy could also establish rules for the use of network equipment, define network permissions, and manage or control data transmitted over the network. More importantly, the network security policy regulates the communication between the network and the Internet.
Industrial espionage is a growing threat to businesses and educational research institutions that thrive on innovation and invention. Computer hackers might use strong tactics like code injection or keylogging software to break into a computer network. Some hackers use the more subtle socio-psychological tact where they trick unwary employees into divulging usernames or sensitive company information, thereby gaining entry into a network. A network security policy establishes rules for employee behavior and provides a clear security engineering policy to protect trade secrets and monitor suspicious activity.
The Network Security Policy also outlines computer security practices for all network users. The policy may indicate appropriate and inappropriate communications between employees, such as prohibiting or monitoring the circulation of personal emails. In the network security policy, users may be required to register all computer devices that access the network, such as laptops and personal devices. The policy clearly specifies acceptable activity and defines all unacceptable activity, including penalties.
One of the fundamental elements in network security policy is the regulation of communications between the network and the Internet. While highly beneficial for external research and communication, the Internet can also provide a direct path to a network security breach. A good network policy takes into account threats from outside as well as inside. Typically, the organization conducts a risk analysis, determines acceptable Internet activity within the network, and specifies or filters Internet access and activity. For example, government or educational websites may be allowed, but viral video websites may be banned or blocked.
A network security policy is only as good as its implementation. The application of political rules is essential. Many businesses and educational institutions may form their own in-house team of network security personnel or hire a security engineering firm. Still others may use special software that monitors and manages all network activity.
