CS0-003 Vulnerability Management Practice Question
A security team is implementing CIS Benchmarks for a Linux server. They need to choose between Level 1 and Level 2 benchmarks. Which of the following best describes Level 1 benchmarks?
⚠ Common exam trap
CS0-004 often tests the confusion between Level 1 and Level 2, where candidates incorrectly associate Level 1 with high-security or mandatory compliance settings rather than its true role as a minimal-disruption baseline.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
They are basic security settings that can be implemented with minimal disruption
CIS Level 1 benchmarks are defined as basic, essential security settings that can be applied with minimal disruption to functionality and are intended for all systems. They represent a practical baseline that most organizations can implement without extensive testing or performance impact, making them suitable as a starting point for hardening. This matches option A's description of basic settings with minimal disruption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
They are basic security settings that can be implemented with minimal disruption
Why this is correct
Level 1 controls, such as disabling unused filesystems or setting basic password policies, are designed to reduce the attack surface without breaking common applications, making them suitable as a default baseline for nearly any server.
- ✗
They are mandatory for compliance with DoD STIGs
Why it's wrong here
CIS Level 1 benchmarks are baseline recommendations intended for all systems, not a DoD STIG mandate; STIGs are separate documents. This option is tempting because both frameworks overlap in hardening guidance, but Level 1 is defined by low performance and functionality impact, not by any specific compliance regime.
- ✗
They are the most restrictive settings, suitable for high-security environments
Why it's wrong here
Level 1 benchmarks are baseline settings with minimal operational impact, not the most restrictive tier; Level 2 covers defence-in-depth for high-security environments. This option is tempting because higher levels do tighten controls, but Level 1 is explicitly the practical, broadly applicable profile.
- ✗
They include advanced settings that require extensive testing
Why it's wrong here
Level 1 covers baseline, essential hardening settings intended for any system with minimal operational impact; extensive testing and advanced, environment-specific controls define Level 2. Choosing it here misstates the level's scope, though it would fit a hardened, high-security deployment where Level 2 is mandated.
