Data protection meets IT security – where GDPR and security complement each other

Useful information
No Comments

Data protection and IT security are often seen as two separate disciplines – but they pursue a common goal: the protection of sensitive data. While the GDPR (General Data Protection Regulation) provides the legal framework, IT security ensures the technical implementation. Those who take a holistic approach to both areas not only protect personal data, but also the trust of customers, partners and employees.

What does the GDPR regulate?

The GDPR obliges companies to process personal data confidentially, securely and for a specific purpose. This includes

  • Protection against unauthorized access
  • Integrity and availability of data
  • Traceability and transparency of processing

These requirements can only be met with technical and organizational IT security.

Where data protection and IT security overlap

1. access management

Only authorized persons may access personal data. This requires clear roles, rights and technical access controls.

2. encryption

Whether during transmission or storage – encryption protects data from unauthorized access and is a central element of both disciplines.

3. logging & traceability

Who accessed which data and when? Logging and monitoring are essential both for security analyses and for GDPR-compliant evidence.

4. data backup & restore

The GDPR requires that data can be restored in the event of an incident – a classic IT security issue.

5. awareness & training

Employees need to know how to handle sensitive data – and how to avoid security incidents. Training is mandatory in both areas.

Conclusion: two sides of the same coin

Data protection without IT security is ineffective – and IT security without data protection is incomplete. Companies that take an integrated approach to both areas not only fulfill legal requirements, but also create a sustainable security culture.
