Operating System Cyber Security
Overview
This unit is designed to introduce the protection, manipulation and analysis of the inner working of operating systems. Students will learn how the Windows and Linux kernels work and study classical computer science topics such as concurrency, scheduling, Windows and Linux memory management. A variety of operating system attacks which use buffer overflows, stack smashing, heap sprays, format strings, race conditions, return to LibC (Return-Oriented Programming), integer overflows, privilege escalation, code injection, sandbox bypass, resource exhaustion and hypervisor bypasses will be studied. Defence techniques will include cryptography, authentication, code signing, containerisation and anti-virus software.

Learning outcomes
Students who successfully complete this unit will be able to:
- Explore the inner workings of modern operating systems, architectures and strategies used to improve hardware performance
- Describe communications and signalling systems used in operating systems
- Describe and implement common data structures and software design patterns in single and multi-threaded applications
- Explain operating system attacks including memory corruption attacks, privacy violations and unauthorised access
- Investigate and demonstrate a variety of software flaws in industrial systems, which allow privilege escalation, unauthorised access and unauthorised code execution
- Analyse and modify operating system source code and utilities, and detect and correct software flaws
- Design and implement tools and procedures which can be used to protect operating systems from a variety of real-world attacks
