According to some embodiments, a security model data store may contain a plurality of potential security policies, each accessible by multiple external applications. A security specifications data store may contain a plurality of potential security specifications, each accessible by the multiple external applications. A security policy engine computer platform may receive from an external application an indication identifying a security policy package. The security policy engine may then retrieve, based on the received indication, one of the potential security models from the security policy data store. Similarly, the security policy engine may retrieve, based on the received indication, one of the potential security specifications from the security specifications data store. The security policy engine may then arrange for a security policy package to be implemented for the external application, the security policy packing being associated with the retrieved potential security model and the retrieved potential security specification.
