CS0-003 Vulnerability Management Practice Question
An organization uses OpenSCAP to perform compliance scanning. The scan results indicate that a system fails to meet a STIG requirement. Which of the following best describes the purpose of STIGs?
⚠ Common exam trap
CS0-004 often tests the confusion between STIGs (DoD configuration hardening guides) and other security frameworks like CVSS (scoring), CIS Benchmarks (industry consensus), or NIST publications, so candidates must remember that STIGs are specifically DoD-developed and prescriptive, not scoring or general industry standards.

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
✓
They are developed by the DoD to secure its information systems
STIGs (Security Technical Implementation Guides) are configuration standards developed by the Defense Information Systems Agency (DISA), a DoD agency, to provide mandatory technical security controls for hardening DoD information systems. They define specific settings, patch levels, and configuration baselines that systems must meet to be authorized for use within the DoD. OpenSCAP uses SCAP content (often derived from STIG benchmarks) to automatically assess compliance against these requirements, which is why a failed STIG check indicates a deviation from DoD-mandated configuration.
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 used solely for web application security
Why it's wrong here
STIGs are DISA configuration checklists covering operating systems, databases, network devices and applications, not web applications alone. It is tempting because web app hardening guidance exists, but OpenSCAP evaluates host and platform settings against STIG benchmarks, so a web-only scope misstates their purpose.
- ✗
They are vulnerability scoring standards
Why it's wrong here
STIGs are prescriptive configuration baselines, not scoring systems; CVSS provides vulnerability severity scores. It is tempting because both support vulnerability management, but OpenSCAP compares system settings against STIG rules, so treating STIGs as scoring standards misidentifies what the scan actually checks.
- ✗
They are industry-standard benchmarks for cloud security
Why it's wrong here
STIGs are US Department of Defense configuration baselines for specific systems, not cloud security benchmarks; the CIS Benchmarks fill that cloud role. It is tempting because both are hardening guidance, but OpenSCAP checks STIG rules on hosts, so cloud-specific benchmarks misstate their scope.
- ✓
They are developed by the DoD to secure its information systems
Why this is correct
STIGs are DoD-published configuration baselines that harden systems against known threats, so this option correctly identifies their origin and purpose. OpenSCAP evaluates a host against these mandated settings, and a failure means the system deviates from the DoD's required secure configuration.
