The correct answer is deterrent control. The warning sign is a physical security control whose primary function is to discourage unauthorized entry by making potential intruders aware of surveillance and consequences, influencing their behavior through the fear of detection or punishment. This directly supports the deterrent category, which aims to reduce the likelihood of an incident before it occurs, unlike preventive controls that physically block access or detective controls that identify incidents after the fact. On the Security+ SY0-701 exam, this distinction tests your ability to differentiate control types by their intent rather than their mechanism—a common trap is confusing a visible camera (which looks like a detective control) with its actual deterrent purpose when placed as a warning. Remember the memory tip: “Deterrent says ‘Don’t try it’; Preventive says ‘You can’t do it.’”
SY0-701 General Security Concepts Practice Question
This SY0-701 practice question tests your understanding of general security concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
To discourage unauthorized entry into a records room, facilities installs a large warning sign, a visible camera over the door, and a turnstile staffed by a guard during business hours. Which control category is the warning sign intended to support most directly?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deterrent
The warning sign is a physical security control designed to discourage unauthorized entry by making potential intruders aware of the risks and consequences. This directly supports the deterrent control category, which aims to reduce the likelihood of a security incident by influencing behavior through fear of detection or punishment. Unlike detective controls that identify incidents after they occur, or preventive controls that physically block access, the sign's primary function is psychological deterrence.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Deterrent
Why this is correct
The sign is meant to discourage people from attempting unauthorized entry in the first place.

✗
Detective
Why it's wrong here
Cameras can help detect activity, but a warning sign primarily seeks to stop attempts before they start.
✗
Preventive
Why it's wrong here
The turnstile is preventive, but the sign itself mainly influences behavior rather than physically blocking access.
✗
Corrective
Why it's wrong here
Corrective controls repair or restore after an incident, which is not the purpose of the warning sign.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the warning sign's purpose with a preventive control, mistakenly thinking that any security measure that stops entry must be preventive, when in fact the sign only discourages rather than physically or logically blocks access.
Detailed technical explanation
How to think about this question
Deterrent controls rely on the psychological principle of perceived risk; a visible camera and warning sign create a sense of surveillance even if the camera is a dummy or the guard is not always watching. In security frameworks like NIST SP 800-53, deterrent controls are often categorized under 'Awareness and Training' (AT) or 'Physical and Environmental Protection' (PE) and are most effective when combined with preventive controls such as the turnstile. Real-world implementations often use signage that references specific legal consequences (e.g., 'Violators will be prosecuted under Title 18 U.S.C. § 1030') to enhance the deterrent effect.

Real-world example
How this comes up in practice
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
