Abstract
A protector device as described for enhancing the security of a computer system which includes one or more user terminals in one or more host computers. The protector device includes a detection means for monitoring communications between the terminals and the host computers in which the detection means is independent from the host computers in the terminal but is connected to the computers and terminals such that certain information transmitted between the computers and terminals is transmitted through the detection means. The detection means includes additional means for user authentication, access control, command filtering, audit trail recording, audit trail analysis, interrogation, and cryptographic services. The detection means further includes means for generating an alarm in the event that certain potentially sensitive events occur and means for interrogating events generated and stored in the detection means.
