HNSEC01-BP02 Implement encryption in transit

Encryption in transit is essential for protecting data confidentiality as traffic moves between on-premises networks and cloud environments. All sensitive data traversing untrusted networks should be encrypted using strong protocols like TLS or IPsec.

Desired outcome: All sensitive data is protected during transmission, meeting regulatory mandates for confidentiality and data integrity.

Level of risk exposed if this best practice is not established: High

Benefits of establishing this best practice:

  • Ensures confidentiality and integrity of sensitive data

  • Meets requirements in regulations such as HIPAA, GDPR, and PCI DSS

  • Reduces risk of breaches and compliance penalties

  • Build customer and auditor trust

Implementation guidance

  • Establish encrypted connections between cloud and on-premises environments.

    For example, you can use services such as AWS Site-to-Site VPN and AWS Direct Connect with MACsec.

  • Enforce HTTPS/TLS for all application traffic between cloud and on-premises environments.

  • Manage and rotate encryption keys according to compliance requirements.
