Data Security

Introduction

Data security is a critical pillar of the governance framework, focused on protecting data from risks associated with storage, access, and handling - particularly threats like ransomware, unauthorized access, and data leaks.

It works hand in hand with Regulatory Compliance, since strong technical safeguards are what make compliance commitments (GDPR, CCPA) actually enforceable in practice.

Key Security Measures

It mainly consists of :

  • Firewalls and access controls to restrict who can reach sensitive systems and data.

  • Credential protection (e.g., strong authentication, secrets management).

  • Encryption of sensitive data, both at rest and in transit. Encryption ensures confidentiality and directly supports compliance with GDPR and other data protection regulations.

  • Disaster recovery plans to ensure business continuity in case of an incident.

  • Employee training on security best practices and threat awareness.

Proactive Risk Management

Security must be integrated into data governance, not bolted on afterward. This requires robust security policies built around:

  • Fine-grained access permissions, ensuring users and systems only access the data strictly necessary for their role.

  • Data classification, tagging data by sensitivity (e.g., public, internal, confidential, restricted) to apply the right level of protection.

  • Regular updates of software and security systems are essential to close vulnerabilities before they can be exploited by cybercriminals.

  • Access traceability, logging and auditing who accessed what data, and when.

  • Incident response procedures, a clear, tested process for detecting, containing, and reporting security incidents.

These measures are essential to prevent unauthorized access and data leaks before they happen, rather than reacting after the fact.

Security and compliance are two sides of the same coin: encryption, access controls, and incident response procedures are what allow the DPO and Privacy Team to credibly report data breaches within GDPR's 72-hour window and to demonstrate, during an audit, that personal data is protected by design, not just by policy.
