Models of Distributed Secure Computing

This chapter aims at providing the architect with a global view of the problem of security, by showing where the paradigms learned in the previous chapter, fit in the several models of distributed secure computing. It starts by discussing the main classes of malicious faults and errors expected in computer systems, and in distributed systems in particular— that is, attacks and intrusions. Then, it equates the main frameworks and strategies for building secure systems authentication, secure channels and envelopes, protection and authorization, and auditing— as a form of bridging from the detail of paradigms to the global view provided by models. Finally, specific models for distributed secure computing are presented.
