Course descriptionComputer 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.
Entry Requirements (not applicable to Visiting Students)
Pre-requisites Co-requisites
Prohibited Combinations Students MUST NOT also be taking Informatics Research Review (INFR11034)
Other requirements This course is open to all Informatics students including those on joint degrees. For external students where this course is not listed in your DPT, please seek special permission from the course organiser.

For some parts of the course, good mathematical ability and basic understanding of logic (predicate calculus) are highly desirable. An ability to program in Java may be assumed for practical exercises.

Summary of Intended Learning Outcomes
1 - recognise the security threats against computer systems, and have at least a high-level idea of the ways to address them;
2 - apply techniques and design principles underlying security solutions, including aspects of cryptography and security protocols;
3 - be able to analyse simple security protocols using a formal method;
4 - be able to use the World Wide Web to research the latest security alerts and information.

Assessment Information
Two exercises. One involving programming such as implementing application-level security features using Java's security APIs or finding and fixing security flaws in a web application written in a scripting language such as Python. The other exercise will be written, requiring solving exercises in cryptography, protocols and network security.

If delivered in semester 1, this course will have an option for semester 1 only visiting undergraduate students, providing assessment prior to the end of the calendar year.

Syllabus * 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.
