Abstract: A port protection network provided with a joint test action group (JTAG) core and method of use. The port protection network includes an agent device operatively connected with a streaming bus and a test access port (TAP) of the JTAG core. The port protection network also includes a master device operatively connected with the streaming bus and the TAP of the JTAG core. In the port protection network, the agent device is configured to selectively restrict access to the master device through the JTAG core.
