How do encryption and cryptographic controls protect AIS data?

• A. They protect confidentiality and integrity; keys are used to encrypt/decrypt data and verify authenticity.
• B. They protect only data at rest.
• C. They protect software licensing.
• D. They are not used in AIS.

Answer: (A)

Encryption and cryptographic controls protect AIS data by ensuring both privacy and trust in the information. Confidentiality is achieved by turning readable data into ciphertext so that only those with the correct key can read it, guarding data from unauthorized access. Integrity and authenticity come from mechanisms like digital signatures and message authentication codes, which let recipients verify that the data hasn’t been altered and that it truly comes from the claimed source. Keys are central to this protection, enabling secure encryption/decryption and verification of origin. In AIS, these controls work for data in transit and data at rest, strengthening overall data security. The idea that cryptographic controls protect only data at rest or are used for software licensing isn’t accurate, and they are indeed applicable and important for AIS.
