What is the relationship between key rotation and data security?

• A. Key rotation eliminates the need for encryption
• B. Key rotation reduces the risk of data being compromised
• C. Key rotation makes decryption impossible
• D. Key rotation is unrelated to security

Answer: (B)

Key rotation reduces the risk of data being compromised. By periodically changing the cryptographic keys used to protect data, you limit how much data could be exposed if a key is stolen or found, and you shorten the time window during which a compromised key can be used. New data gets encrypted with fresh keys, which helps contain any potential breach and supports ongoing secure access. Rotating keys does not remove encryption or make decryption impossible—old data can still be decrypted with the keys that protected it, and new data is protected by the current keys. This practice is a security-focused measure to limit impact and improve key management.
