Perimeter Security

 

Globally networked businesses rely on their networks to communicate with employees, customers, partners, and suppliers. While immediate access to information and communication is an advantage, it raises concerns about security-protecting access to critical network resources.

 

Network administrators need to know who is accessing which resources and establish clear perimeters to control that access. An effective security policy balances accessibility with protection. Security policies are enforced at network perimeters. Often people think of a perimeter as the boundary between an internal network and the public Internet, but a perimeter can be established anywhere within a private network, or between your network and a partner’s network.

 

A solid perimeter security solution enables communications across it as defined by the security policy, yet protects network resources from breaches or attacks. It controls multiple network entry and exit points. It also increases user assurance by implementing multiple layers of security.

 

The most common form of perimeter security is a firewall. This is a system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria.

 

Another complementary system to firewalls are called Intrusion Detection Systems (IDS). These are systems that try to identify attempts to hack or break into a computer system or to misuse it. IDS’s may monitor packets passing over the network, monitor system files, monitor log files, or set up deception systems that attempt to trap hackers.
