WM144-18 Operating Systems in the Cyber Context
Introductory description
An operating system performs two main tasks. Firstly, it provides a simplified, logical view of a computer where the quirks of particular hardware devices and the intricacies of their use are hidden behind consistent software interfaces. The operating system also provides several powerful, simplifying views of aspects of the computer such as files, folders and processes, none of which actually exists. Secondly, it manages the resources offered by a computer, making sure that, if there are several active users, they get their fair share of the CPU, memory, storage and peripherals. Even if there is only one user, they may be running several programs at once and the operating system will manage the competing demands from each program. This module will outline the principles of how an operating system is constructed, how it works, and its critical role in cyber security. This module gives a solid understanding of how a modern operating system satisfies its requirements in the cyber context.
Module aims
Articulate the key principles behind the organisation and operation of a typical general-purpose operating system.
Explain how simple process, memory and file management algorithms and data structures work.
Select and apply security and protection mechanisms.
