Automating Enrichment and Triage

Premium

Security analysts spend much of their time on repetitive triage and enrichment tasks. Even simple automation can save hours of manual work and reduce fatigue.

“Seasoned analysts will run through a similar methodology of investigating a phishing email that they have seen a thousand times. Building an automation that saves them minutes per investigation will compound into days of saved time by year end.” ~ K.O., CEO, Astro InfoSec

Interviewers look for candidates who think beyond manual investigation. They are looking for candidates who can:

  • Identify tasks that are repetitive or error-prone
  • Use simple tools to improve triage
  • Explain how automation supports faster, more accurate analysis
  • Balance automation with human review for critical decisions

Automation tasks

These are the common tasks that are ideal for automation in SOC operations. Internalise this information so that you can quickly call out where you can use automation in an interview scenario. This will impress your interviewers.

TaskAutomation exampleValue to the SOC
Alert enrichmentScript pulls IP or hash reputation from VirusTotal or OTX APIsReduces lookup time and adds context automatically
IOC correlationBash or Python script checks indicators across multiple logsFinds reuse or propagation quickly
Case documentationTemplate scripts generate investigation summariesKeeps tickets consistent and detailed
Log parsingScheduled grep or jq filters for key patternsSaves time on repetitive searches
Notification and escalationWebhook or Slack automation for critical alertsEnsures rapid awareness and response

Automation tools

While you need not know how to use all these tools, showing awareness of how and why to use them and integrating that in your explanation of automating tasks will show experience and credibility.

CategoryTool or exampleWhy it’s useful
Command-line utilitiescurl, grep, jq, awkGreat for lightweight data handling and API calls
ScriptingPowerShell, Bash, PythonQuick automation for lookups or triage
APIsVirusTotal, AbuseIPDB, ShodanPull external threat intelligence on demand
SOAR platformsSplunk Phantom, Microsoft Sentinel PlaybooksCombine automation with workflow management
ChatOps integrationsSlack or Teams webhooksNotify analysts automatically for high-severity alerts

How automation questions are phrased

If you don’t realize that interviewers often want to hear about automation, it’s easy to miss those questions entirely. They might not use the word “automation” directly, so take a look at how some of these questions are phrased. This will help you recognize when an automation-related question is being asked.

“How would you speed up the investigation of phishing alerts?”

What interviewers are looking for: Process awareness and ability to identify bottlenecks

“Can you describe a simple automation you built or used?”

What interviewers are looking for: Hands-on experience and impact

“How would you use scripting to enrich indicators automatically?”

What interviewers are looking for: Logical thinking and understanding of data flow

“How would you ensure automation does not create false positives?”

What interviewers are looking for: Judgment and operational balance
