The CCTV system and signs about the possibility of being filmed serve as both deterrent and detective controls.
Deterrent controls: Aim to discourage potential attackers from attempting unauthorized actions.
Posting signs about CCTV serves as a deterrent by warning individuals that their actions are being monitored.
Detective controls: Identify and record unauthorized or suspicious activity. The CCTV system itself functions as a detective control by capturing and recording footage that can be reviewed later.
Preventive controls: Aim to prevent security incidents but are not directly addressed by the CCTV and signs in this context.
Corrective controls: Aim to correct or mitigate the impact of a security incident.
Directive controls: Provide guidelines or instructions but are not directly addressed by the CCTV and signs.
Compensating controls: Provide alternative measures to compensate for the absence or failure of primary controls.
