Enforcing access to endpoint resources
Techniques are directed to controlling access to resources on a message bus of a network communication device. The techniques may include, by the network communication device, processing a message bus access policy file uniquely corresponding to a process. The message bus access policy file may include a certificate securely associating the message bus access policy file with the process. The techniques may further include, by the network communication device, based at least in part on the processing the message bus access policy file, exposing one or more resources of the network communication device to the process on the message bus, in a manner corresponding to at least one resource access permission indication contained within the message bus access policy file.
