Risk assessment across frameworks
Compare risk assessment across SOC 2, ISO 27001, GDPR, and HIPAA, including scope, methodology, DPIAs, ePHI analysis, evidence, and SaaS cadence.
Frameworks covered: SOC 2, ISO/IEC 27001, GDPR, HIPAA
Key differences
| Dimension | Approach A | Approach B |
|---|---|---|
| SOC 2 | CC3.2 identifies business risks and CC3.4 evaluates significant changes; CC9.1 addresses risk mitigation. | Management chooses a suitable method, and the CPA tests whether the described process and related controls are designed and operating. |
| ISO 27001 | Clauses 6.1.2–6.1.3 require defined, consistent criteria for information-security risk assessment and treatment. | Results drive treatment options, control determination, Annex A comparison, risk-owner approval, residual acceptance, and the SoA. |
| GDPR | Articles 24, 25, and 32 require measures responsive to risks to individuals; Article 35 requires a DPIA for likely high-risk processing. | A DPIA describes processing, necessity, proportionality, rights risks, and mitigations; residual high risk may trigger Article 36 consultation. |
| HIPAA | §164.308(a)(1)(ii)(A) requires an accurate and thorough assessment of risks and vulnerabilities to ePHI. | The analysis must cover all ePHI and feed risk management; a generic enterprise heat map that omits systems and threats is insufficient. |
| Risk subject | SOC 2 and ISO commonly frame risk to service commitments and organizational information-security objectives. | GDPR centers rights and freedoms of people, while HIPAA focuses confidentiality, integrity, and availability of ePHI. |
| Required output | SOC 2 evidence may include registers, meetings, change reviews, and mitigation tracking; ISO additionally expects treatment and SoA linkage. | GDPR may require DPIA records, and HIPAA needs a scoped ePHI risk-analysis record plus remediation decisions. |
| Cadence | All four expect updates when systems, threats, vendors, products, or processing materially change—not an annual checkbox alone. | Periodic review is useful, but event-driven reassessment and closure tracking make the process operational. |
Control overlap
One SaaS risk taxonomy and scoring system can reduce duplication, but each framework needs the correct lens. A central register can map risks and treatments to SOC 2 CC3.2/CC3.4/CC9.1, ISO Clauses 6.1.2–6.1.3, GDPR Articles 24/32/35, and /controls/hipaa/164-308-a-1. Asset inventories, architecture reviews, threat models, vendor assessments, vulnerability trends, incidents, and change tickets are reusable inputs. Preserve distinct outputs: the ISO treatment plan and SoA, GDPR DPIAs focused on individuals, and HIPAA’s complete ePHI risk analysis. A single row labeled “privacy/security risk” without affected systems, threat, vulnerability, impact, owner, treatment, and acceptance will rarely withstand serious review.
Sequencing advice
For SaaS, begin with a reliable inventory of products, cloud accounts, data stores, integrations, vendors, people, and regulated data flows. Define scoring criteria and acceptance authority, then workshop concrete scenarios with engineering, privacy, and operations—credential compromise, tenant isolation failure, data export, cloud outage, malicious insider, and subprocessor breach. Create the enterprise register, branch high-risk personal-data changes into DPIAs, and ensure every ePHI location appears in the HIPAA analysis. Map selected treatments to SOC 2 controls and the ISO SoA, assign deadlines, and track residual acceptance. Reassess during architecture review and vendor onboarding, not only before an audit.
