Available to year(s) of study:
Available to Study Abroad / Exchange Students: Yes Full Year Module Available to Study Abroad / Exchange Students for a Single Term: No Comments: PreRequisite - For programming assignments, knowing programming is essential, preferably in Python.
|Module is taught during the following terms
This course considers security as it relates to a single computer at an introductory level. Cryptography is introduced and the various scenarios that involve encryption and authentication are investigated. There will be practical work that will give students an opportunity to explore key security tools. The management and planning issues are covered in policy and risk management.
After completing this module, students will be expected to be able to:
1. Identify and describe common security vulnerabilities.
2. Recommend security tools and procedures for specific attacks.
3. Describe the nature of malicious code and how it can spread, be identified and removed.
4. Compare the performance of various cryptographic schemes.
Principles of security
-Confidentiality, integrity and availability (CIA)
-Vulnerabilities, threats, controls
-Forensics and recovery of systems
-Internal and external scanning
-Log file analysis
-Common problems in applications
-Detailed example of stack based buffer overflow
Malware and malicious code
-Viruses, trojans, worms
-History and classification
-Anatomy of a virus and how viruses spread
-Identifying viruses and antivirus software
-Applications of encryption to computer security
-Types of encryption algorithms
-Examples of encryption algorithms commonly used
-Key and password management
- Hash functions, one way functions, examples
-Methods of user authentication
-Biometric access control (e.g. fingerprint, iris etc.)
-Other techniques (e.g. smartcard)
-Example security policy
