Recent times have seen a proliferation of digital devices and the subsequent concern for the security of information. This unit introduces students to the basic principles and practices of computer and information security. Focus will be on the software, operating system and network security techniques with detailed analysis of real-world examples. Topics include cryptography, authentication, software and operating system security, network security, mobile security, and legal and ethical issues. In addition, the unit promotes and strengthens important generic skills, such as communication, analysis and inquiry, problem solving, independent and group working, and professionalism and social responsibility. This unit may be cotaught with 6697 Computer and Network Security PG.

Learning outcomes

On successful completion of this unit, students will:
1. Describe basic cryptographic functionality, including symmetric ciphers, public key encryption, and digital signatures;
2. Evaluate the security of systems that use cryptography and secure communication techniques;
3. Identify the vulnerability of information systems and justify specific security technologies, settings, and parameters that can improve system security design;
4. Describe existing secure network architectures by applying security technologies such as firewalls, intrusion detection systems, and malicious software scanners; and
5. Discuss how privacy and social engineering issues can impact system design.
