📋ISO 27001 A.5.34Rule: ISO27001-A534high

Privacy and Protection of PII

Description

The organisation shall identify and meet the requirements regarding the preservation of privacy and protection of personally identifiable information (PII).

⚠️ Risk Impact

PII handling without privacy controls produces GDPR, CCPA, DPDP, and PIPL exposure simultaneously. Modern privacy regulations carry penalties materially higher than security regulations.

🔍 How EchelonGraph Detects This

ISO27001-A534Automated 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.

🔧 Remediation

Maintain PII data inventory. Apply data minimisation (collect only what's necessary). Implement DSR (Data Subject Request) handling: access, correction, deletion. Privacy by Design in new product features.

💀 Real-World Attack Scenario

A SaaS company collected employee diversity data 'for HR analytics' without documented purpose limitation. When an audit asked 'why this data?', the team had no answer. GDPR Article 5(1)(b) purpose-limitation violation; €1.8M penalty. The data wasn't necessary; it had been collected because 'we might use it someday'.

💰 Cost of Non-Compliance

GDPR violations: up to €20M / 4% revenue. CCPA violations: $2,500 per record. DPDP violations: up to ₹250 crore.

📋 Audit Questions

  • 1.Show the PII data inventory.
  • 2.What is the documented purpose for each data category?
  • 3.How are Data Subject Requests handled? What is the SLA?
  • 4.Show Privacy by Design evidence for last 3 product features.

T1530 — Data from Cloud Storage

⚡ Common Pitfalls

  • Collecting data without documented purpose ('we might need it')
  • Manual DSR handling — slow, error-prone
  • Privacy as legal-only function — engineering teams unaware

📈 Business Value

Strong privacy controls reduce regulatory exposure across multiple jurisdictions simultaneously. Increasingly material for B2C and B2B-with-individuals products.
