What security measure should be taken for data stored in transit?

1. Network segmentation

2. Encryption

3. Regular backups

4. User training

The correct answer is: Encryption

When considering data stored in transit, encryption serves as a crucial security measure. This approach ensures that any data being transmitted over a network is converted into a coded format that can only be read by authorized parties. By encrypting data in transit, even if an unauthorized individual intercepts the data packets, they would be unable to decipher the information without the correct decryption key. Encryption protects against various threats, including eavesdropping, man-in-the-middle attacks, and other forms of data breaches that might occur while data travels across networks. It maintains the confidentiality and integrity of the data, ensuring that sensitive information remains safe from unauthorized access. While other options like network segmentation, regular backups, and user training are important for security, they do not specifically address the vulnerability of data in transit. Network segmentation primarily protects internal networks, regular backups are essential for data recovery, and user training focuses on human factors in cybersecurity. However, none of these measures directly encrypt or secure data being transmitted. Thus, encryption stands out as the appropriate and effective measure to protect data during transit.
