ISC2 Systems Security Certified Practitioner (SSCP) Practice Question
Your organization is building a small on-premises analytics room that will host servers processing confidential research data. The perimeter fence and lobby badge readers are already in place. You have been asked to recommend an additional detective control for the server room itself that can feed real-time evidence to the security operations center without impeding daily access. Which option BEST meets this requirement?
Install closed-circuit television (CCTV) cameras with continuous recording of all entrances and interior areas.
Add dual-factor biometric locks to the server-room door.
Build an anti-passback mantrap that requires two people to enter together.
Enclose the room in a Faraday cage to block electromagnetic emissions.
Closed-circuit television (CCTV) provides continuous monitoring of the room and records evidence that can be reviewed by the SOC. Because it observes and records events rather than preventing them, CCTV is classified as a detective control.
Biometric locks and a mantrap are primarily preventive because they stop unauthorized entry rather than detect it after the fact.
A Faraday cage limits electromagnetic emissions (a preventive technical control) but does not detect unauthorized physical activity. Therefore, CCTV is the most appropriate detective control for the server room.
