A General Mechanism for Access Control: Its Relationship to Secure System Concepts

Keywords :
Abstract : The paper contributes to the clarification of what is meant by security in data processing systems. It is based on a general access control mechanism, which has been described in previous papers and is here modified to become more general. The mechanism is justified informally and is then used in discussing security. The paper describes the use of the mechanism to help define security requirements form the users' point of view and to help describe the correspondence of that definition to a more detailed view. Finally, it offers the basic assumptions of the mechanism as a contribution to the meaning of "security".
