The institutions of higher learning need to reap the benefits of the internet revolution by integrating ICT into the learning environment. The focus is to improve the quality of education and lay a good foundation at the higher learning institution and encourage the institution and its affiliated colleges to share the resources, knowledge content, promotion, and implementation of e-governance, faculty development and exchange of skills. Campus networks are interconnected with high speed Ethernet links operating over optical fiber such as Gigabit Ethernet and 10 Gigabit Ethernet. Tiered hierarchal architecture is used to establish a Campus network with core, distribution & access segments for efficient flow of information & data traffic. Important PointsA Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet. Hence the Campus Wide Network in a University includes a firewall. The main purpose of using a firewall is to restrict the access.

It is a broad process that includes various tools, techniques, and standards to ensure that the messages are unreadable when in transit between two or more network nodes.
