What is the general purpose of encryption tools as described?

• A. To safeguard the contents of an organization's data when stored or transmitted.
• B. To monitor network traffic passively
• C. To detect and exploit vulnerabilities
• D. To deprotect data after expiration

Answer: (A)

Encryption tools protect the contents of data by transforming readable information into an unreadable form using cryptographic keys, and only someone with the correct key can restore it to readable form. This keeps information confidential whether it’s stored on devices (at rest) or sent over networks (in transit). By making data unreadable to anyone who intercepts it or accesses it without authorization, encryption defends sensitive information from eavesdropping, theft, and tampering. The other activities described—monitoring network traffic, discovering or exploiting vulnerabilities, or removing protection after a certain expiry—aren’t about keeping data secret, which is why they don’t describe encryption’s purpose.
