The Security Reference Model (SRM) is one of the Reference Models of the IndEA Framework (#IndEASRM) and the Federal Enterprise Architecture Framework (#FEAFSRM).

The SRM delineates the overall framework for providing information security to the entire gamut of IT systems in the enterprise. Integrity, privacy, confidentiality, and availability of information / IT systems are the key concerns addressed by SRM.

SRM adopts a layered approach to identifying and meeting the information security needs of the enterprise. The model identifies the security controls to be applied at 6 layers, namely, the Business Layer, Data Layer, Application Layer, Perimeter Layer, Network Layer and the End Point Layer. SRM also touches upon the manner of designing Security Policies and Standard Operating Procedures.
