In today’s cyber threat landscape, protecting sensitive data is an absolute priority for any organization in Romania. Effective data encryption, both when stored on physical media or in the cloud (at rest) and during transfer over public or private networks (in transit), constitutes a critical line of defense. The correct implementation of these measures significantly reduces the risk of confidentiality compromise in the event of a security incident.
Practical recommendations for implementing encryption
- Using modern protocols for data in transit: Implement exclusively secure protocols, such as TLS 1.3 for web traffic (HTTPS), and disable outdated versions to prevent man-in-the-middle attacks.
- Full Disk Encryption (FDE): Ensure that all laptops, servers, and mobile devices storing data at rest use full storage drive encryption, utilizing established technologies such as BitLocker or LUKS.
- Centralized cryptographic key management: Protect cryptographic keys through dedicated KMS (Key Management Service) solutions, ensuring their periodic rotation and restricting access based on the principle of least privilege.
- Column or table-level database encryption: For highly sensitive information, apply encryption directly in the database (Transparent Data Encryption) to limit exposure in case of unauthorized physical or logical access to the server.
- Securing internal network communications: Do not assume that the local network is secure by default; use IPsec or TLS VPNs for connections between locations and encrypt sensitive traffic between internal servers.
Adopting these best practices is not only a technical protection measure, but also a legal necessity for companies targeted by the new European regulations. The NIS2 Directive and the DORA regulation impose strict requirements regarding cyber resilience and data protection, transforming encryption from a security recommendation into a mandatory pillar of operational compliance in Romania.
