What is a common method for securing sensitive data?

• A. Using plain text storage for easy access
• B. Regularly changing system passwords
• C. Encrypting data at rest and in transit
• D. Limiting the number of devices connected to a network

Answer: (C)

Encrypting data at rest and in transit is a fundamental method for securing sensitive data. This practice protects information by transforming it into an unreadable format, so that even if unauthorized individuals gain access to the data, they cannot interpret it without the appropriate decryption key. Encryption at rest involves securing data stored on physical or virtual devices, such as hard drives or cloud storage. This ensures that, in case of theft or unauthorized access, the data remains protected. Encryption in transit secures data as it travels across networks, safeguarding it from interception and eavesdropping during transmission. Together, these measures significantly enhance data confidentiality and integrity, making them essential components of a comprehensive security strategy. Other methods like changing passwords or limiting connected devices, while useful, do not directly address the protection of sensitive data in the same comprehensive manner as encryption does.
