Abstract
A computer device and method are described for controlling access to a resource. An execution environment executes a user process with access privileges according to a user security context. A security unit controls access to resources according to the user security context, with the user process making system calls to the security unit. A proxy hook module embedded within the user process intercepts the system call and generates a proxy resource access request. A proxy service module in a privileged security context validates the proxy resource access request from the proxy hook module and, if validated, obtains and returns a resource handle that permits access to the desired resource by the user process.
