Undergraduate Course: Computer Security (INFR09025)
|School||School of Informatics
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 9 (Year 3 Undergraduate)
||Availability||Available to all students
|Summary||Computer Security is concerned with the protection of computer systems and their data from threats which may compromise integrity, availability, or confidentiality; the focus is on threats of a malicious nature rather than accidental. This course aims to give a broad understanding of computer security. Topics include security risks, attacks, prevention and defence methods; techniques for writing secure programs; an overview of the foundations for cryptography, security protocols and access control models.
* Introduction and background. Risks and attacks: to privacy (theft, surveillance); integrity (fraud); availability (vandalism, denial of service). Additional security properties: authentication, accountability.
* Cryptography: basic functional foundations. Symmetric algorithms, for example: DES, Rijndael, RC4
* Public key cryptography. Algorithms including RSA, ElGamal. Hash functions, including SHA-1. Digital signatures and certificates.
* Authentication: mechanisms and attacks. Protocols for authentication and key exchange, including Needham-Schroeder, Otway-Rees, Kerberos, Diffie-Hellman.
* Formal approaches, including Burrows-Abadi-Needham logic for authentication and its application to security protocol analysis.
* Malicious code and network defences: Trojan horses, viruses and worms, attacks on faulty code. Auditing, intrusion detection, alarms and honey pots.
* Security engineering: security policy models, multi-level systems. Secure kernels and trusted computing bases. Anatomy of attacks, risk assessment, attack trees.
* Present internet technologies, for example: PGP, SSL, SSH, SMIME, DNSSEC, IPsec, firewalls and VPNs. The Java Security Model and security programming in Java.
* Copyright protection. Secure hardware and tamper resistance. Steganography and covert communication. Anonymity.
* Security futures, real-world issues. Topics chosen from: web security, e-commerce and e-cash; legalities; export control, key escrow; information warfare and cyber terrorism; human factors. Recent research areas.
