CSC3124 : System and Network Security

Semesters
Semester 2 Credit Value: 10
ECTS Credits: 5.0

Aims

To create awareness of the need for security in computer and communications systems, and to introduce some of the technical mechanisms by which security can be achieved.

By exploring topics such as the need for security, system and network security, cryptography, authentication and digital signatures, as well as the legal and political aspects of security, this module aims to create awareness of the need for security in computer and communications systems and to introduce some of the technical mechanisms by which security can be achieved.

Outline Of Syllabus

The need for security: threats and risks.
System Security: simple forms of authentication, penetrations and their antidotes, protection mechanisms, capabilities, access control lists. Network Security: openness of networks, network-based attacks, firewalls.
Cryptography: simple methods and their inadequacies, symmetric cryptography, DES, IDEA, RC4, public key methods and algorithms, RSA, Diffie/Hellman, elementary cryptanalysis.
Authentication: messsage digests, authentication protocols and systems. Digital Signatures: techniques, applications, e-commerce.
Secure coding.

Assessment Rationale And Relationship

The written examination is an appropriate way to assess knowledge of the theoretical underpinnings and practical skills on small-scale problems. The examination involves the correct interpretation and analysis of formal models. Its duration is set to allow time for this to be done accurately.

The coursework assessment gives an opportunity to assess practical skills on a more realistic and open-ended problem.

N.B. This module has both “Exam Assessment” and “Other Assessment” (e.g. coursework). If the total mark for either assessment falls below 35%, the maximum mark returned for the module will normally be 35%.
