ICT318 Network Security provides a broad overview on the concept and importance of network security. By learning the basics of encryption, students can understand how the use of keys protect information for Internet applications by verifying the origin of a message (also known as authentication), proving the contents of a message are not modified after sending (integrity), and ensuring the sender cannot deny sending the message (nonrepudiation). Students will also be able to explain how security is implemented at the Application, Transport and Network layers of the TCP/IP stack. In addition, network security technologies that protect the computer network against any theft of information and malicious attacks will be presented, including firewalls, Intrusion Detection and Prevention Systems (IDPS), and IEEE 802.11i.
