System Monitoring

Description

Monitor the system to detect attacks, indicators of compromise, and unauthorized connections.

⚠️ Risk Impact

Without monitoring, attacks go undetected until significant damage occurs.

🔧 Remediation

Enable monitoring and alerting across all systems. EchelonGraph provides centralized security monitoring dashboard.

💀 Real-World Attack Scenario

A government cloud environment had GuardDuty enabled but no human review process for findings. Over 6 months, GuardDuty generated 2,400 findings including credential exfiltration, bitcoin mining, and unauthorized API calls — all ignored. The actual breach was discovered by a journalist investigating leaked citizen data.

💰 Cost of Non-Compliance

SolarWinds 2020 demonstrated the cost of monitoring gaps in government: $100M+ remediation. Average government breach without active monitoring: $8.2M. CISA considers SI-4 a critical control.

📋 Audit Questions

  • 1.What monitoring tools are deployed?
  • 2.How are monitoring alerts triaged and escalated?
  • 3.Show evidence of responding to monitoring alerts.
  • 4.What is your mean-time-to-detect for security incidents?

⚡ Common Pitfalls

  • Monitoring tools deployed but findings not reviewed by humans
  • Alert fatigue from uncurated alert rules (too many false positives)
  • Monitoring only network traffic but not API activity and data access

📈 Business Value

Active system monitoring transforms security tools from expensive paperweights into actual defenses. The difference between collecting alerts and RESPONDING to alerts is the difference between a detected and undetected breach.
