SSSS (or 4S) is Smart Site Safety System. It consists of server, workstation, mobile network, end point devices (CCTV, smart watch, RFiD helmet, other sensors) to monitor construction site and workforce situation for safety hazards alert.
For client project involving civil works, equipment installation etc, contractor will bring their own 4S to ensure and compliance with safety rules and regulations. 4S is not a project deliverable but a tool during construction.
I see some cybersecurity practitioners have incorrect understanding. They demand contractor 4S compliance with own organization cybersecurity policies. No doubt 4S might capture client site specific condition, coincidental inclusion of personnel other than contractor workforce causing privacy concerns. We must not forget there are administrative controls in the contractual obligation to comply with laws & regulation plus non-disclosure agreement. We shall not bother the how’s in technical aspects. Otherwise, this is overkilled.
This something like you walk into a mall, using the ATM – there are CCTV everywhere but you won’t question what are technical controls in these systems. Your mission is to ensure your privacy is protected via laws & regulations.
