A Security Operations Centre (SOC) is the team and tooling that monitors, detects and responds to threats around the clock.

The SOC Detection Workflow

How a Security Operations Centre turns raw logs into action.

Log sources

Collect everything.

Endpoints, servers, firewalls, cloud and identity systems forward logs. Good coverage is the foundation of detection.

How it works

Collect — a SIEM aggregates logs from endpoints, network, cloud and identity into one place.
Detect — correlation rules and analytics turn raw events into alerts; good detection engineering reduces noise.
Triage — analysts investigate alerts, separating false positives from real incidents, then escalate.
Tiers — Tier 1 triages, Tier 2 investigates deeper, Tier 3 hunts and engineers detections.

This is the SOC Analyst role in action and leads straight into Incident Response.

Interview Intelligence

How this topic actually shows up in interviews — and how to demonstrate you understand it.

Why employers ask about this

SOC skills are in high demand and are the most common entry point into cyber security.

Technical questions

Walk me through triaging a security alert.+

Validate the alert, gather context (user, host, logs), decide true/false positive, then escalate or close with notes.

Behavioural questions

Describe staying focused under a high alert volume.+

Show prioritisation, tuning noisy rules and methodical triage.

Real-world scenarios

“You get 500 alerts from one rule overnight.”+

Expected answer: Investigate a sample, confirm it's a false positive, tune the rule, and document — reducing noise sustainably.

Frequently asked questions

What is a SIEM?

Security Information and Event Management — a platform that centralises logs and generates security alerts from correlation and analytics.

What does a SOC analyst do?

Monitors alerts, triages them to separate false positives from real threats, investigates and escalates incidents.

Why are false positives a problem?

They cause alert fatigue and waste time; good detection tuning keeps analysts focused on real threats.
