"Solid 'ground up' covering on the technical aspects of security - authentication, authorisation, privacy, non-repudiation etc. Covers technology in good depth, ideal for Comp. Sci. students."
"A dated book covering older the algorithms - but does do exceedingly well. The fundamentals are there but the book is aimed more at engineers and implementers not architects and planners."
"Aimed very much at hackers and programmers / developers. This book is best read by someone with a solid grasp of computer architectures and basic grasp of assembly language and debugging."
"An excellent guide pointing out pitfalls and best-practice. Contains ample case-studies which highlight problems and their severity an the limitations of security methods and processes."
