Network and Communication Security Protocols

Objectives

Network and communications security is an important part of IT security since most cyberattacks are performed either using network connections or are targeting network infrastructure. The course focuses on the most common weaknesses and attacks on network protocols, and on the use of security protocols and protection techniques for computer networks and communication. It will also investigate some standard tools for automated network security testing and monitoring. Completing the course will contribute to a better understanding of network security risks and how to counter them.

Learning outcomes for the course are defined in terms of knowledge, skills and general competence as follows

Knowledge

Learners will understand

• the TCP/IP protocol layering model
• solutions for key distribution using symmetric and asymmetric cryptography
• network security issues and how these are addressed at different layers by appropriate security protocols

Skills

Learners will be able to

• identify potential network vulnerabilities and suggest relevant countermeasures
• use tools for network security testing and monitoring
• use and promote secure networking practices

General competence

The student can explain security-related issues to a non-technical audience, suggest security solutions and argue for them.
