Security Operations Center (SOC) automation is a critical component of modern cybersecurity, enabling teams to detect, investigate, and respond to threats efficiently. Prescott Pym and Chris Horsley recently discussed SOC automation at AUSCERT 2025, highlighting best practices, common pitfalls, and how to integrate software development principles into SOC workflows.
You Should Know:
1. Core Components of SOC Automation
- Incident Triage Automation – Use tools like TheHive, Cortex, or Splunk Phantom to automate initial threat assessment.
- Playbook Execution – Leverage SOAR (Security Orchestration, Automation, and Response) platforms to standardize response actions.
- Threat Intelligence Integration – Automate enrichment using MISP (Malware Information Sharing Platform) or OpenCTI.
2. Good SOC Automation Patterns
✅ Modular Playbooks – Break workflows into reusable components.
✅ CI/CD for Detection Rules – Use GitHub + Sigma rules for automated rule deployment.
✅ Feedback Loops – Continuously improve automation with post-incident reviews.
3. Bad Patterns to Avoid
❌ Over-Automation – Not all alerts should trigger automated responses.
❌ Lack of Testing – Untested playbooks can cause false positives/negatives.
❌ Ignoring Human Oversight – Always keep analysts in the loop for critical decisions.
4. Key Commands & Tools for SOC Automation
- Linux (Log Analysis & Automation):
Use grep for log filtering grep "Failed password" /var/log/auth.log Automate log parsing with awk awk '/sshd.invalid user/ {print $9}' /var/log/auth.log | sort | uniq -c Use jq for JSON-based log processing cat alerts.json | jq '.alerts[] | select(.severity == "high")' -
Windows (SIEM Integration & Automation):
Query Windows Event Logs Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625} Automate with PowerShell scripts Invoke-WebRequest -Uri "https://threat-intel-feed.com/iocs" -OutFile "iocs.json" -
SOAR Tooling (Example: TheHive + Cortex):
Create a new case via API curl -XPOST -H "Authorization: Bearer YOUR_API_KEY" -d '{"title":"Phishing Alert"}' http://thehive:9000/api/case
What Undercode Say
SOC automation is not about replacing humans but augmenting their capabilities. The best SOCs blend AI-driven automation with human expertise, ensuring rapid response while minimizing errors. Avoid “set and forget” automation—continuously refine playbooks based on real-world incidents.
Prediction
By 2026, SOC automation will heavily integrate Generative AI for anomaly detection, reducing false positives by 40%. Open-source SOAR solutions will dominate mid-sized enterprises due to cost efficiency.
Expected Output:
- A well-structured SOC automation pipeline with modular playbooks.
- Reduced MTTD (Mean Time to Detect) and MTTR (Mean Time to Respond).
- Seamless integration between threat intelligence and incident response.
