Summary***PLEASE NOTE: This course has been replaced by a 20 credit version - INFR10067 Computer Security, please see the entry for that course.***

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.
Course description * 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.

Learning Outcomes
On completion of this course, the student will be able to:
  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.
