Introduction

Qualys Vulnerability Management, Detection, and Response (VMDR) is a critical tool for identifying, assessing, and mitigating security risks in enterprise environments. As organizations increasingly rely on cloud and hybrid infrastructures, expertise in Qualys VMDR, Policy Compliance (PC), and Security Configuration Assessment (SCA) is in high demand. This article provides hands-on commands, configurations, and best practices for cybersecurity professionals looking to master Qualys.

Learning Objectives

  • Understand core Qualys VMDR workflows for vulnerability scanning and remediation.
  • Learn how to configure and optimize Qualys Policy Compliance (PC) and SCA modules.
  • Implement automation scripts for Qualys API integration and report generation.

You Should Know

  1. Running a Basic Vulnerability Scan with Qualys API

Command:

curl -H "X-Requested-With: Curl" -u "username:password" \
"https://qualysapi.qualys.com/api/2.0/fo/scan/" \
-d "action=launch&scan_title=My_VM_Scan&ip=192.168.1.1-192.168.1.100&option_id=12345"

Step-by-Step Guide:

1. Replace `username:password` with your Qualys API credentials.

  1. Modify the `ip` range to target your network.
    3. `option_id` refers to a predefined scan template (e.g., “Full Scan”).

4. Execute via terminal to initiate the scan.

2. Automating Compliance Checks with Qualys PC

Command (PowerShell):

$headers = @{"X-Requested-With"="PowerShell"}
$cred = Get-Credential
Invoke-RestMethod -Uri "https://qualysapi.qualys.com/api/2.0/fo/compliance/policy/" `
-Method Post -Headers $headers -Credential $cred `
-Body "action=list&show_fields=id,title"

Step-by-Step Guide:

1. Retrieves a list of compliance policies.

2. Use `-Credential` for secure authentication.

3. Extend with `-Body` parameters to filter results.

3. Exporting Qualys Scan Results via API

Command:

curl -H "X-Requested-With: Curl" -u "username:password" \
"https://qualysapi.qualys.com/api/2.0/fo/scan/" \
-d "action=fetch&scan_ref=scan/12345678&output_format=pdf"

Step-by-Step Guide:

1. Replace `scan_ref` with your scan ID.

2. Set `output_format` to CSV, XML, or PDF.

3. Save results for audit or remediation tracking.

4. Hardening Linux Systems Using Qualys SCA

Command (Linux Audit):

sudo qualys-cloud-agent --enable-scanner --scanner-type=sca

Step-by-Step Guide:

1. Installs the Qualys Cloud Agent for SCA.

2. Runs security configuration assessments against CIS benchmarks.

3. Review findings in the Qualys dashboard.

5. Integrating Qualys with SIEM (Splunk Example)

Splunk Query:

index=qualys_vmdr severity=5 | stats count by ip, dns, qid

Step-by-Step Guide:

1. Configure Qualys to forward logs to Splunk.

2. Use SPL queries to track critical vulnerabilities.

3. Set up alerts for high-severity findings.

What Undercode Say

  • Key Takeaway 1: Qualys VMDR automation reduces manual workload, enabling faster vulnerability remediation.
  • Key Takeaway 2: API integration with SIEM tools enhances real-time threat visibility.

Analysis:

Qualys remains a dominant force in vulnerability management, but professionals must adapt to cloud-native deployments. Future trends include AI-driven prioritization and automated patch orchestration. Organizations that leverage Qualys API integrations will gain a competitive edge in threat mitigation.

Prediction

By 2025, Qualys will incorporate more machine learning features for predictive vulnerability scoring, reducing false positives and optimizing remediation workflows. Professionals skilled in Qualys automation will be indispensable in enterprise security teams.
