CS0-003 Vulnerability Management Practice Question
During a vulnerability assessment, a security analyst uses a tool that identifies missing patches and misconfigurations based on CIS Benchmarks. Which of the following tools is specifically designed for compliance scanning against CIS benchmarks?
⚠ Common exam trap
CS0-004 often tests whether candidates can distinguish SCAP-native compliance tools from general vulnerability scanners — the trap is picking a well-known commercial scanner like Nessus or Qualys when the question specifically asks for CIS benchmark compliance scanning.

Correct answer & explanation
✓
OpenSCAP
OpenSCAP is an open-source implementation of the Security Content Automation Protocol (SCAP) that natively consumes SCAP content, including CIS Benchmarks delivered as XCCDF/OVAL datastreams. It is specifically designed for compliance scanning and remediation against benchmarks like CIS, PCI DSS, and STIG. Running 'oscap xccdf eval' against a CIS benchmark profile produces a compliance report mapped to the benchmark's controls.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
OpenSCAP
Why this is correct
OpenSCAP is an open-source security compliance tool designed specifically to audit systems against standardized security baselines, such as the Center for Internet Security (CIS) benchmarks and DISA STIGs. It utilizes the Security Content Automation Protocol (SCAP) to automate configuration compliance checking and vulnerability assessment, making it the ideal choice for verifying adherence to specific security frameworks.
- ✗
Qualys
Why it's wrong here
Qualys is an enterprise-grade, cloud-based vulnerability management platform designed for continuous asset discovery, threat prioritization, and patch management across global infrastructures. While it possesses compliance modules, its primary design and industry-standard deployment focus on broad-spectrum vulnerability detection and risk management rather than being a dedicated, lightweight SCAP-compliant engine.
- ✗
Nessus
Why it's wrong here
Nessus, developed by Tenable, is a widely used proprietary vulnerability scanner that primarily focuses on identifying missing patches, software flaws, and misconfigurations. Although it can ingest audit files to perform compliance checks, its core architecture is optimized for network-based vulnerability assessments rather than native, command-line-driven SCAP compliance auditing.
- ✗
OpenVAS
Why it's wrong here
OpenVAS (Open Vulnerability Assessment System) is an open-source network vulnerability scanner that operates as part of the Greenbone Vulnerability Management (GVM) framework. It relies on a feed of Network Vulnerability Tests (NVTs) to detect active security exploits and system vulnerabilities, lacking the native SCAP-engine capabilities required for formal CIS benchmark compliance validation.
