The answer is accountability, and the most effective long-term solution is to implement multi-factor authentication. The sticky note password incident reveals a failure in accountability because the security policy requiring strong, regularly changed passwords was not enforced, and the employee’s behavior was not held to a standard of responsibility. Multi-factor authentication (MFA) directly addresses this by adding a second verification layer, such as a one-time code or biometric, so that even if a password is compromised, an attacker cannot log in without the additional factor. On the ISC2 Certified in Cybersecurity CC exam, this scenario tests your understanding of the Accountability principle under the Security Principles domain, often paired with a trap where candidates choose “training” or “stronger passwords” instead of recognizing that MFA is the most effective technical control. A common memory tip: think of the sticky note as a “password leak” that MFA seals—Accountability requires enforcement, and MFA provides that enforcement without relying on user memory.
ISC2 CC Security Principles Practice Question
This CC practice question tests your understanding of security principles. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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's security policy requires that all employees use strong passwords and change them every 90 days. An employee writes their password on a sticky note and attaches it to their monitor. Another employee sees it and uses it to log into the first employee's account to send a fake email. The security team is conducting a post-incident review. Which security principle failed, and what is the most effective long-term solution to prevent this type of incident?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Correct: The failure is in enforcement of policy and user behavior (accountability). The most effective solution is to implement multi-factor authentication (MFA) (B), which reduces reliance on passwords. Option A is wrong because shorter passwords are weaker; Option C is wrong because training alone is often insufficient; Option D is wrong because disabling sticky notes is hard to enforce.
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.
✗
Integrity; conduct annual security awareness training
Why it's wrong here
Training is useful but often not enough to change behavior completely.
MFA ensures that a password alone is not sufficient for access.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Availability; prohibit sticky notes in the office
Why it's wrong here
Prohibiting sticky notes is difficult to enforce and does not address the root cause.
✗
Confidentiality; enforce 15-character passwords
Why it's wrong here
Longer passwords help but don't prevent users from writing them down.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.
