What is a key reason to use encryption and access controls for electronic data in CBP operations?

• A. To improve data readability for travelers.
• B. To ensure data integrity and confidentiality by protecting sensitive information from unauthorized access.
• C. To reduce storage space.
• D. To allow public access to all records.

Answer: (B)

The key idea is protecting sensitive electronic data from unauthorized access and alteration. Encryption makes data unreadable without the proper keys, whether it sits in storage or moves across networks, so even if someone intercepts it, they can’t read it. Access controls enforce who can log in, view, modify, or share data, applying the principle of least privilege and requiring authentication and auditing. Together, these measures maintain confidentiality and integrity of CBP information such as personal data, travel records, and enforcement details, which is essential for privacy, compliance, and operational security. The other options don’t fit because encryption is not about readability for travelers, it doesn’t aim to reduce storage space, and opening records to the public would defeat the purpose of protecting sensitive information.
