Abstract: In one implementation, a security management system accesses a trusted location signature and a candidate location signature to determine that the candidate location signature is correlated with the trusted location signature, and establishes a trusted state of an entity in response to determining that the candidate location signature is correlated with the trusted location signature.

Abstract: Examples herein disclose monitoring an expected functionality upon execution of a system management mode (SMM) BIOS code. The examples detect whether a change has occurred to the SMM BIOS code based on the monitoring of the expected functionality. The change indicates that the SMM BIOS code is compromised.

Abstract: A data processing system supporting a secure domain and a non-secure domain comprises a hardware component, and a processor device having operating modes in the secure domain and non-secure domain, the processor device to execute a secure application in the secure domain. The hardware component has a property having a secure state. The property of the hardware component in the secure state may only be reconfigured responsive to instructions received from the secure domain. The secure application is operative to implement a configuration service to configure the property of the hardware component in the secure state, responsive to a request received from the non-secure domain according to an application programming interface associated with the secure application.
