PR.DS-02

The confidentiality, integrity, and availability of data-in-transit are protected

Implementation examples

Ex1: Use encryption, digital signatures, and cryptographic hashes to protect the confidentiality and integrity of network communications
Ex2: Automatically encrypt or block outbound emails and other communications that contain sensitive data, depending on the data classification
Ex3: Block access to personal email, file sharing, file storage services, and other personal communications applications and services from organizational systems and networks
Ex4: Prevent reuse of sensitive data from production environments (e.g., customer records) in development, testing, and other non-production environments
