1 |
Access Control |
This verification case will test the access control requirements of the CCTV system. Requirements include the CCTV System Manager assigning access control to the other user roles as well as the CCTV System allowing the various users to receive distributed video, select cameras, control cameras and controlling video distribution. The requirements also cover the CCTV System Maintainer running diagnostics and testing and allowing External Systems to also receive distributed video, select cameras, control cameras and controlling video distribution. The CCTV System user access control capabilities will be verified in accordance with their corresponding requirements. For the most part, no additional hardware or software besides the CCTV System itself is envisioned to accomplish this verification test, however the interfacing External Systems will be needed to verify the requirements involving the
External Systems. |
