How Computer Systems Work | Cybersecurity Fundamentals for Beginners
Understand enterprise SOC operations, tier escalation models (Tier 1 Triage, Tier 2 Incident Response, Tier 3 Threat Hunting), SIEM log ingestion architectures, and key operational metrics (MTTD & MTTR).
💡 Learning Accelerator:
1. The Structure of a Modern Security Operations Centre
A Security Operations Centre (SOC) serves as the centralized nerve center for enterprise cyber defense.
SOC Analyst Tier Hierarchy:
- Tier 1 (Triage Analyst): Initial monitoring, filtering false positives, alert validation, and preliminary ticket creation.
- Tier 2 (Incident Responder): Deep-dive artifact analysis, containment execution, root-cause isolation, and host remediation.
- Tier 3 (Senior Analyst / Threat Hunter): Proactive threat hunting, detection engineering, adversary emulation, and advanced forensic review.
Key Performance Indicators (KPIs):
- Mean Time to Detect (MTTD): Elapsed time between initial compromise and security alert generation.
- Mean Time to Respond / Remediate (MTTR): Elapsed time between alert detection and complete containment/neutralization.
