APPARATUS AND METHODS FOR RESTRICTED BINDING OF PORTS

Abstract:

An electronic device includes a port binding module that binds ports to processes. A process running on the electronic device sends a port request to the port binding module. The port binding module determines whether the requested port is a restricted port. If not, the port binding module binds the requested port to the process. If the requested port is restricted, then the port binding module determines whether the requesting process has an entitlement corresponding to the port. If the requesting process has the corresponding entitlement, then the port binding module binds the requested restricted port to the process. If not, then the port binding module denies binding the requested restricted port to the process.
