What Is Security Engineering?
Ross Anderson · 2020
Security engineering focuses on the tools, processes, and methods needed to design, implement, and test complete systems, and to adapt existing systems as their environment evolves. Getting protection right thus depends on several different types of process. Readers need to ensure that the people who will guard the system and maintain it are properly motivated. In this chapter, the author sets out a framework for thinking about this. Then, in order to illustrate the range of different things that security and safety systems have to do, he takes a quick look at four application areas: a bank, a military base, a hospital, and the home. The author provides a few brief examples of interesting security systems and what they're designed to prevent. Military systems were the other technology driver back in the 20th century, as they motivated much of the academic research that governments funded into computer security from the early 1980s onwards.
