Communications and Network Security
Access Time: 30 Days
This course contains a discussion of communications and network security. It covers 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.
The content in this course aligns with Domain Four in the CISSP exam, offered by (ISC)2. However, the course can be taken as a stand-alone without the intention of sitting for the exam.
After completing this course, you'll be able to:
- 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.
