CCIRC recommends that system owners enact their organization’s life-cycle process for affected devices, and test/deploy replacement solutions. To aid with mitigation of the vulnerabilities, network access to affected devices should be controlled, isolated and protected. In particular, access to port 80 on affected devices should be restricted.
