Telecommunications and Network Security

Telecommunications and Network Security is fundamental to our modern life. The Internet, the World Wide Web, online banking, instant messaging e-mail, and many other technologies rely on Network Security: our modern world cannot exist without it. Telecommunications and Network Security (often called “telecommunications,” for short) focuses on the confidentiality, integrity, and availability of data in motion. Telecommunications is one of the largest domains in the Common Body of Knowledge and contains more concepts than any other domain. This domain is also one of the most technically deep domains, requiring technical knowledge down to packets, segments, frames, and their headers. Understanding this domain is critical to ensure success.
