  • Patent number: 5032979
    Abstract: The distributed auditing subsystem invention runs in a UNIX-like operating system environment with a hierarchical file system. The invention provides an audit trail of accesses to the objects it protects and maintains and protects that audit trail from modification or unauthorized access or destruction. The audit data generated by the invention is protected so that read access to it is limited to those who are authorized for audit data. The invention enables the recording of events which are relevant to the maintenance of the security of the system, such as the use of identification and authentication mechanisms, the introduction of objects into a user's address space, the deletion of such objects, actions taken by computer operators and system administrators and/or system security officers, and other security relevant events. The invention generates an audit record for each recorded event which includes the date and time of the event, the user, the type of event, and the success or failure of the event.
