1. A security platform for a UNIX-based system comprising:

  • at least one rule, each rule directly defining a type of access in terms of subject, a subject being an entity type for which access is permitted by the rule and which encompasses users, system resources and other entity types, and two or more objects, an object being the entity types to which the access relates in the order listed and which encompass users, system resources and other entity types;

    means for comparing requested access by an entity type, requested access being defined by an access demand which identifies the access type of interest and defines that access type in terms of subject and objects, to the defined at least one rule to determine if requested access is permitted based upon the correspondence between the terms making up the requested access with the terms defining the at least one rule; and

    means for providing a positive response when access is permitted and a negative response when access is not permitted.
