CS0-003 Vulnerability Management Practice Question
An organization uses CIS Benchmarks to secure its Linux servers. The security team applies Level 1 benchmarks. Which of the following best describes Level 1 CIS benchmarks?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Basic security configurations with minimal operational impact
CIS Level 1 benchmarks are basic security configurations that cause minimal disruption to business operations. Level 2 is more restrictive and may impact functionality.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Advanced security settings that may reduce functionality
Why it's wrong here
CIS Level 2 benchmarks introduce more stringent security controls, often requiring significant system changes and potentially impacting application compatibility or performance. These advanced settings prioritize a higher security posture over ease of implementation or minimal operational disruption, which is a key differentiator from the more foundational Level 1 recommendations. Therefore, this option incorrectly describes Level 1.
- ✗
Required for all internet-facing systems
Why it's wrong here
While implementing CIS Level 1 benchmarks is highly recommended for enhancing the security of any system, including those exposed to the internet, they are not universally 'required' by regulatory bodies or industry standards specifically for all internet-facing systems. Level 1 provides a strong, general baseline for improving security across an organization's entire IT infrastructure, rather than being a specific mandate tied solely to external network exposure. This makes the statement inaccurate.
- ✓
Basic security configurations with minimal operational impact
Why this is correct
CIS Level 1 benchmarks are meticulously designed to establish a foundational security posture across various systems without significantly disrupting business operations or demanding extensive resources. These basic security configurations focus on essential hardening steps that are broadly applicable and easy to implement, ensuring a robust security baseline can be achieved with minimal risk of system instability or performance degradation. This approach makes them highly practical for widespread adoption.
- ✗
Only applicable to DoD environments
Why it's wrong here
CIS Benchmarks are developed by the Center for Internet Security, a non-profit organization, and are widely adopted globally across commercial, government, and educational sectors as general cybersecurity best practices. They are distinct from Security Technical Implementation Guides (STIGs), which are specifically mandated by the Defense Information Systems Agency (DISA) for systems operating within U.S. Department of Defense (DoD) environments. Therefore, stating they are only applicable to DoD environments is incorrect.
