IDEF was created by the United States Air Force and is now being developed by Knowledge Based Systems. Originally developed for the manufacturing environment, IDEF methods have been adapted for wider use and for software development in general. Sixteen methods, from IDEF0 to IDEF14 (and including IDEF1X), are each designed to capture a particular type of information through modeling processes. IDEF methods are used to create graphical representations of various systems, analyze the model, create a model of a desired version of the system, and to aid in the transition from one to the other. IDEF is sometimes used along with gap analysis. The following table lists the IDEF methods either current or in development. IDEF0 through IDEF4 are the methods most commonly used. IDEF METHODS IDEF0 Function Modeling IDEF1 Information Modeling IDEF1X Data Modeling IDEF2 Simulation Model Design IDEF3 Process Description Capture IDEF4 Object-Oriented Design IIDEF5 Ontology Description Capture IDEF6 Design Rationale Capture IDEF7 Information System Auditing IDEF8 User Interface Modeling IDEF9 Scenario-Driven IS Design IDEF10 Implementation Architecture Modeling IDEF11 Information Artifact Modeling IDEF12 Organization Modeling IDEF13 Three Schema Mapping Design IDEF14 Network Design As an example of the process, IDEF0 methods are used to model the functions of an enterprise, creating a graphical model that shows: what controls the function, who performs it, what resources are used in carrying it out, what it produces, and what relationships it has to other functions.

The SANS Institute recommends that organizations should take time to educate their employees about computer security and periodically test employees to make sure they understand the basics.
