What are the two types of data encryption mentioned?

• A. At rest and in transit
• B. In use and at rest
• C. Stored and in motion
• D. Active and passive

Answer: (A)

Data encryption is a fundamental aspect of securing information in any system, including ServiceNow. The two types of data encryption mentioned are commonly referred to as encryption at rest and encryption in transit.

Encryption at rest protects data that is stored on physical devices. This form of encryption ensures that data is secured when it is not actively being transmitted or processed, making it unreadable to unauthorized users if they gain access to the storage medium.

Encryption in transit, on the other hand, safeguards data as it moves across networks. This form of encryption secures data during transmission between servers and clients, preventing interception and unauthorized access while the data is actively being transferred.

Together, these two types of encryption provide a comprehensive security approach, protecting data both when it is being stored and when it is being communicated across networks. This dual focus is critical in preventing data breaches and ensuring the confidentiality and integrity of sensitive information.
