From University Video Communications' catalog:"A secure computer system is one that can be trusted to carry out its owner's security policy. A distributed system has many parts usually connected by insecure wires; often there is no common manage-ment that everyone trusts. The basic services for building a secure system are authentication, authorization, and auditing; they are hard to implement in a distributed system. This lecture describes how to set up secure communication channels using encryption, establish a hierarchy of servers to authenticate the users of these channels, grant access to the authorized users listed on each object, and record each step in an audit trail."
