What is the difference between data security (Datensicherheit) and data protection (Datenschutz)?
Data security protects hardware, software, and data from loss, destruction, and unauthorized access. Data protection protects natural persons from violations of their personal rights through data processing.
| Data Security | Data Protection | |
|---|---|---|
| Protects | Hardware, software, data | Natural persons (people) |
| Against | Loss, destruction, misuse by unauthorized parties | Violations of personality rights |
| Focus | Technical systems and their integrity | Individual rights and freedoms |
| Legal basis | IT security standards, organizational policies | GDPR, revDSG, constitutional rights |
Why both are needed:
- Data security without data protection: Your systems are secure, but you still process personal data without legal basis or consent
- Data protection without data security: You respect privacy rights on paper, but your systems are vulnerable to breaches
The relationship: Data security is a prerequisite for data protection — you can't protect personal rights if your systems aren't secure. But security alone isn't sufficient; you also need legal compliance and ethical data handling.
Tip: Think of data security as the "lock on the door" (technical measures), and data protection as the "rules about who can enter and what they can do inside" (legal and ethical framework).
