Interprocess Communications

A system that is configured with Solaris Trusted Extensions enforces mandatory access control (MAC) and discretionary access control (DAC). Access control is enforced between communicating processes on the same host and across the network. This chapter summarizes the interprocess communication (IPC) mechanisms that are available in a system configured with Trusted Extensions. This chapter also discusses how access controls apply.

For examples of how the Trusted Extensions APIs are used in the Solaris OS, see the Solaris source code. Go to the Open Solaris web site and click Source Browser in the left navigation bar. Use the Source Browser to search through the Solaris source code.

This chapter covers the following topics:

• Multilevel Port Information

• Communication Endpoints
