Risk Assessment

Description

Conduct risk assessments of the system; document risk assessment results; review and update assessments periodically.

⚠️ Risk Impact

Without documented risk assessment, control prioritization is opinion. Auditors test whether security activities are risk-driven or arbitrary. The latter produces qualified opinions.

πŸ” How EchelonGraph Detects This

NIST-RA-003Automated scanner rule

EchelonGraph's Tier 1 Cloud Scanner automatically checks for this condition across all connected cloud accounts. Violations are flagged as high-severity findings with remediation guidance.

πŸ”§ Remediation

Annual formal risk assessment + continuous incremental risk review. Document threat sources, vulnerabilities, likelihood, impact, controls. Tie to risk register (CC3.2). Brief leadership on top risks.

πŸ’€ Real-World Attack Scenario

A federal contractor's risk assessment was 3 years old. The threat landscape had shifted dramatically (ransomware-as-a-service maturity, supply-chain attack normalization, deepfake fraud emergence) β€” none reflected in their controls. A ransomware attack exploited a vector their old risk assessment didn't anticipate. The post-incident review traced the gap directly to stale risk assessment.

πŸ’° Cost of Non-Compliance

Stale risk assessments as breach contributor: 31% of major 2024 incidents (Mandiant M-Trends). FedRAMP RA-3 deficiencies: blocks ATO renewal.

πŸ“‹ Audit Questions

  • 1.When was the last formal risk assessment?
  • 2.What threats does it cover? Are ransomware, supply chain, AI-enabled fraud included?
  • 3.How is the assessment updated as threat landscape evolves?
  • 4.Who reviews + approves the assessment?

⚑ Common Pitfalls

  • β›”Risk assessment as one-time annual document β€” irrelevant by month 4
  • β›”Generic threat library not tailored to your business + technology stack
  • β›”No leadership review β€” assessment exists but doesn't drive resource decisions

πŸ“ˆ Business Value

Living risk assessment is the navigation system for security investment. Without it, the security team is responding to fashion, not threat.
