Abstract: Component access control includes: receiving, by an access control module, permissions specifying authorization of physical access to one or more secured components of a computing system by one or more requestors; receiving, by the access control module from a requestor, a request to physically access one of the secured components of the computing system; determining, by the access control module based on the permissions, whether the requestor is authorized to physically access the secured component; and responsive to determining that the requestor is authorized to physically access the secured component, granting the requestor physical access to the secured component while prohibiting the requestor from physically accessing other secured components of the computing system.
