CISSP Security Assessment and Testing Practice Question
This CISSP practice question tests your understanding of security assessment and testing. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which TWO of the following are key objectives of a security assessment? (Select exactly 2.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Identify vulnerabilities in systems and applications.
A is correct because identifying vulnerabilities is a primary objective of a security assessment, such as a vulnerability scan or penetration test, which systematically discovers weaknesses in systems and applications (e.g., missing patches, misconfigurations, or insecure code). B is correct because assessing the effectiveness of existing security controls (e.g., firewalls, IDS/IPS, access controls) is a core goal, often achieved through control testing or validation to determine if controls are properly implemented and functioning as intended.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Assess the effectiveness of existing security controls.
Why this is correct
Evaluating control effectiveness is a core assessment objective.

✗
Exploit vulnerabilities to gain unauthorized access.
Why it's wrong here
Exploitation is part of penetration testing, not a general assessment objective.
✗
Prioritize threats based on business impact.
Why it's wrong here
Threat prioritization is part of risk management, not the assessment phase.
✗
Implement new security controls to address findings.
Why it's wrong here
Implementation is a remediation step, not part of the assessment itself.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the objectives of a security assessment (identify vulnerabilities and assess controls) with the objectives of a penetration test (exploit vulnerabilities) or risk management (prioritize threats), leading them to select options C or D incorrectly.
Detailed technical explanation
How to think about this question
A security assessment typically follows a structured methodology like NIST SP 800-115, which includes phases such as planning, discovery, and analysis. Under the hood, vulnerability identification relies on tools like Nessus or OpenVAS that compare system configurations against CVE databases, while control effectiveness is evaluated through techniques like penetration testing or control validation (e.g., verifying that a firewall rule actually blocks specific traffic). In a real-world scenario, a security assessment might reveal that a web application has a SQL injection vulnerability (CVE-2023-XXXX) and that the WAF rule intended to block it is misconfigured, highlighting both the vulnerability and control failure.
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.
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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
