Which of the following is the function of confirming the veracity of a property trust of data claimed by an entity?

Correct option is A

The correct answer is (a) Authentication
Explanation:
• Authentication is the process of verifying the identity of a user, device, or entity to ensure they are who they claim to be.
• In data security, it confirms the veracity or truthfulness of the credentials (like passwords or biometrics) provided.
• It is the first line of defense in cybersecurity, ensuring that unauthorized entities cannot access a system.
• It can be categorized into single-factor or multi-factor authentication (MFA).
• Verifying the "property trust of data" involves ensuring the source of the data is authentic and untampered.
Information Booster:
• The AAA framework in security stands for Authentication, Authorization, and Accounting.
• Common methods include Passwords, Security Tokens, and Biometric Verification (Fingerprints, Facial Recognition).
