Appropriate Data Security Measures Under Rule 6(a)

To comply with the obligation to implement reasonable security safeguards, companies should adopt a combination of technical and organizational measures. Below is a detailed list:

 

1. Data Encryption

  • Use strong encryption for personal data at rest and in transit.
  • Apply SSL/TLS protocols for secure data transfer over the internet.
  • Ensure encryption keys are stored securely (e.g., using a Hardware Security Module (HSM)).

 

2. Data Obfuscation and Masking

  • Mask sensitive data (e.g., PAN, Aadhaar, mobile number) before displaying it to unauthorized users or third parties.
  • Use data tokenization where actual data is replaced by surrogate values (tokens).
  • Apply format-preserving masking for testing and analytics environments.

 

3. Secure Authentication & Access Controls

  • Implement Multi-Factor Authentication (MFA) for employees and systems accessing personal data.
  • Enforce role-based access control (RBAC) and the principle of least privilege.
  • Regularly audit and review access permissions.

 

4. Use of Virtual Tokens

  • Replace personal identifiers (like customer ID, name, email, mobile number) with unique tokens that are mapped in a secure token vault.
  • Prevent reverse-engineering of tokens by applying cryptographic methods or non-reversible hashes.

 

5. Endpoint and Network Security

  • Use firewalls, Intrusion Detection and Prevention Systems (IDPS), and antivirus software.
  • Segment networks to isolate sensitive data zones.
  • Secure endpoints (laptops, mobile phones) via MDM (Mobile Device Management) solutions.

 

6. Application Security

  • Ensure secure coding practices
  • Perform Vulnerability Assessments and Penetration Testing (VAPT) regularly.
  • Use Web Application Firewalls (WAF) to protect APIs and websites.

 

7. Data Minimization and Classification

  • Classify data based on sensitivity (e.g., Public, Internal, Confidential, Restricted).
  • Retain only the minimum required data and for the required period (data retention policy should be documented specifying the data to be retained and time period upto which retained).
  • Anonymize personal data when used for analytics or testing.

 

8. Employee Training and Awareness

  • Conduct regular data privacy and security awareness programs.
  • Train employees to recognize phishing, malware, and social engineering attempts.

 

9. Secure Physical Storage and Disposal

  • Secure physical servers/data centers with biometric access controls and CCTV surveillance.
  • Shred physical documents containing personal data.
  • Ensure secure wiping of devices before disposal or reassignment.

 

10. Continuous Monitoring and Incident Response

  • Implement SIEM (Security Information and Event Management) tools for real-time monitoring.
  • Define and test an Incident Response Plan (IRP) to react promptly to data breaches.
