Abstract
A method for establishing and maintaining a security policy for a device can include establishing a secure channel between a secure execution environment (SEE) operating on the device and a security entity external to the device. The method can also include configuring, by a security manager executing on the SEE, access to sensitive operations of an environment interactor coupled to the device based on a security policy provided from the security entity. The method can further include resetting, by the security manager, a secure watchdog timer in response to a reset authorization token provided from the secure entity. If the secure watchdog timer expires a given predetermined number of times since a last reset authorization token is received, the security manager executes a given prescriptive operation dictated by the security policy.
