A Security Operations Center (SOC) is the centralized function that monitors, detects, investigates, and responds to security events. SOC analysts watch dashboards, investigate alerts, hunt for threats, and coordinate incident response. The SOC serves as the organization’s security nerve center, providing 24/7 visibility into the security posture.
SOC capabilities include security monitoring using SIEM, threat intelligence integration, incident triage and escalation, and coordination with IT operations for remediation. SOC maturity ranges from basic alert monitoring to advanced threat hunting and automated response.
