This CCSP practice question tests your understanding of cloud application security. 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.
A company is deploying a containerized application on Kubernetes. The security team requires that containers run with the least privilege, and that any attempt to escalate privileges within a container is blocked. Which Kubernetes security context setting should be applied to the pod specification?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "least"
Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
allowPrivilegeEscalation: false
Option D is correct because setting `allowPrivilegeEscalation: false` in the pod's security context directly blocks any attempt by a container process to gain more privileges than its parent process, such as through setuid binaries or syscalls like `setuid()`. This satisfies the requirement to prevent privilege escalation within the container, aligning with the least privilege principle.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
runAsNonRoot: true
Why it's wrong here
Ensures container runs as non-root user but does not block privilege escalation.
✗
capabilities: drop: ['ALL']
Why it's wrong here
Drops all capabilities but if the container runs as root, it can still gain capabilities via setuid binaries.
✗
readOnlyRootFilesystem: true
Why it's wrong here
Makes root filesystem read-only but does not prevent privilege escalation.
✓
allowPrivilegeEscalation: false
Why this is correct
Prevents privilege escalation, which is the exact requirement.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
ISC2 often tests the distinction between preventing privilege escalation and other security controls like dropping capabilities or running as non-root, leading candidates to confuse capability removal with escalation prevention.
Detailed technical explanation
How to think about this question
Under the hood, `allowPrivilegeEscalation` controls the `no_new_privs` flag in the Linux kernel, which when set prevents the process from gaining new privileges via `execve()` of setuid/setgid binaries or file capabilities. In Kubernetes, this flag is enforced by the container runtime (e.g., containerd) via the OCI runtime spec. A real-world scenario is a container that runs a web server as a non-root user but has a vulnerable binary with the setuid bit; without this setting, an attacker could exploit that binary to escalate to root.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
