Abstract
Performing security sensitive operations with an application security model. Security agnostic code is executed. The security agnostic code is identified as not having authorization to perform a security sensitive operation. Executing the security agnostic code includes calling code identified as security safe critical code. In response to the security agnostic code calling the security safe critical code, the security safe critical code is executed. The security safe critical code includes functionality for performing validity checks. Executing the security safe critical code includes performing an validity check for the security agnostic code. When the security agnostic code passes the validity check, code identified as security critical code is called. In response to the security safe critical code calling the security critical code, the security critical code is executed. The security critical code is authorized to perform the security sensitive operation.
