A Security Operations Center (SOC) is not just tools. It is a hierarchy of Analysts (Tier 1, Tier 2, Tier 3) handling thousands of alerts per day.
The Hierarchy
- Tier 1 (Triage): Fresh graduates. They stare at the SIEM "Dashboard of Pain". They filter out false positives. "Is this a real attack or just Bob from IT forgetting his password?"
- Tier 2 (Responder): If Triage says it's real, Responder investigates. They isolate the machine and scan for malware.
- Tier 3 (Hunter): Senior experts. They don't wait for alerts. They proactively hunt for threats that the tools missed.
1. Alert Fatigue
The #1 enemy of a SOC.
If your SIEM generates 10,000 alerts a day, the analysts will ignore them.
A good SOC Manager spends their time TUNING the rules to reduce noise.
2. Playbooks (SOAR)
Security Orchestration, Automation, and Response.
Automating the repetitive tasks.
"If an IP fails login 50 times, AUTO-BLOCK it at the firewall."
This lets humans focus on the complex analysis.
