Network Security (40 Hours)

What’s the course about

Network security is concerned with granting access to a network to the authorized users, and denying access to a network by the unauthorized users. It encompasses the actions to prevent attacks from viruses, worms, and Trojan horses; spyware and adware; zero-day/zero-hour attacks; hacker attacks; denial of service attacks; data interception and theft, and identity theft. A network security consists of many hardware and software components.

A switch acts as a controller - it manages how various devices within a local network share information among themselves. The router acts as a dispatcher - it chooses the best route for sending and receiving information across a local and an external network or Internet. Routing and switching functions are all about planning and fixing routers and switches in a network.

Course objectives

The course teaches students the three important network security measures: 1) how to protect vital information and allowing access to them only to authorized users, 2) provide authentication and access control for resources, and 3) guarantee availability of resources - computers, servers, and other devices.
