Cyber Security - recommended reading I'm applying for a doctoral training in Cyber Security, although I come from a maths background. I've been told that my background meets the entry criteria, although for my application I would like to be able to say that I've looked into Cyber Security it at least some detail.

Given that I will have very little time to do any reading before applying (about 2 weeks), what would you recommend I read? A few chapters from an academic text, or a popular book on the topic?

Specific book/paper recommendations would be appreciated.
Take a peek at Anderson's classic "Security Engineering" (PDF legally available for free at the link). It won't help you with the details, but it gives an overview of the whole area, for (more or less) laypeople.
