Communication and Network Security

This course covers topics related to communications and network security. It begins with a lesson in the different types of networks and different transmission technologies. It also covers the two main models that govern how networks work: the OSI model and the TCP/IP model, as well as their related layers. The course includes a detailed discussion of the many protocols that allow networks and network devices to communicate with one another and includes a discussion of firewalls and wireless networks. This course is designed for IT professionals and other adult learners who are interested in gaining an introduction to information technology security.

Learning Outcomes:

• Discuss the general concepts that enable networking and its role in information technology
• Compare the different types of networks, including LANs, WANs, and MANs, as well as the Internet, intranets, and extranets
• Explain what the Open Systems Interconnection (OSI) Reference Model is and identify its seven layers
• Contrast the OSI model with the TCP/IP Model
• Identify common protocols and differentiate between network, routing, and data link protocols
• Describe the functions of common networking devices, including bridges, routers, hubs, repeaters, switches, and firewalls
• Discuss how wireless networks work and the technology that enables them
• Identify common network attacks and how they can be prevented
