Abstract: A method and system for controlling computer security. The system is a centralized, computer-network security management tool capable of handling many different kinds of equipment in a standardized format despite differences in the computer security features among the diverse range of computer equipment in the computer network. The invention uses a layered software architecture, including a technology specific layer and a technology independent layer. The technology specific layer serves to extract and maintain security data on target platforms and for converting data to and from a common data model used by the technology independent layer. The technology independent layer handles the main functionality of the system such as locating and removing certain present and former employees from computer access lists, auditing system user data, monitoring security events (e.g.
