Abstract
Systems and methods for enforcing mandatory access control in a message-based operating system are provided. Calls to operating system logic may be passed as messages over communication channels in a message-based operating system. A first process configured to receive a message via a communication channel in a message-based operation system may be identified. In addition, the communication channel may be identified. Further, an access rule may be identified. The access rule may be a rule to govern access to the communication channel. The access to the communication channel by the second process may be controlled based on the access rule. The access may be controlled in a kernel of a message-based operating system. The second process may be configured to execute invocation logic. The invocation logic may be executable to send the message via the communication channel.
