What is a Security Operations Center (SOC)?
A Security Operations Center (SOC) is a dedicated facility that monitors, detects, analyzes, and responds to cybersecurity threats in real time. A 24/7 SOC provides continuous protection of an organization’s IT infrastructure — 24 hours a day, 7 days a week, 365 days a year.
In an era where the average time to identify a breach is 197 days (IBM Cost of a Data Breach Report) and the average incident cost exceeds $4.45 million, a SOC is not a luxury — it’s a necessity.
Why 24/7 and not business hours only?
Attackers don’t work 9-to-5:
- 76% of ransomware attacks happen outside business hours (nights, weekends)
- Average time from breach to data exfiltration is 9 hours — if SOC doesn’t operate at night, the attack completes before the morning shift
- NIS2 and DORA regulations require incident reporting within 24 hours — without 24/7 SOC you may not meet the deadline
SOC architecture: people, processes, tools
People
A 24/7 SOC requires a minimum of 8-12 analysts working in 3 shifts:
| Role | Count | Responsibility |
|---|---|---|
| L1 Analyst (Triage) | 4-6 | Initial alert analysis, classification, escalation |
| L2 Analyst (Investigation) | 2-4 | Deep incident investigation, event correlation |
| L3 Analyst (Hunt) | 1-2 | Threat hunting, malware analysis, forensics |
| SOC Manager | 1 | Team management, reporting, process oversight |
Core tools
| Category | Tools | Purpose |
|---|---|---|
| SIEM | Splunk, Microsoft Sentinel, Elastic, QRadar | Log correlation, alerting |
| SOAR | Palo Alto XSOAR, Splunk SOAR, TheHive | Automated incident response |
| EDR | CrowdStrike, SentinelOne, Defender for Endpoint | Endpoint protection |
| NDR | Darktrace, Vectra, ExtraHop | Network traffic analysis |
| TIP | MISP, Anomali, Recorded Future | Threat Intelligence |
What SOC monitors
- Network — firewall, IDS/IPS, proxy, DNS, NetFlow
- Endpoints — workstations, servers, mobile devices (EDR)
- Cloud — AWS CloudTrail, Azure Activity Log, GCP Audit Logs
- Identity — Active Directory, Entra ID, SSO, MFA events
- Applications — application logs, WAF, API gateway
- Email — anti-phishing, DLP, attachment analysis
Deployment models
| Model | Cost | Best for |
|---|---|---|
| In-house SOC | $500K-$1.5M/year | Large enterprises, critical infrastructure |
| Managed SOC | $2K-$10K/month | Mid-size companies, fast deployment |
| Hybrid SOC | $300K-$800K/year | Organizations with existing security team |
Key SOC metrics
| Metric | Target | Why it matters |
|---|---|---|
| MTTD (Mean Time to Detect) | < 1 hour | How fast you spot incidents |
| MTTR (Mean Time to Respond) | < 4 hours | How fast you contain them |
| False Positive Rate | < 30% | Signal vs noise ratio |
