Which cloud security control is a countermeasure for man-in-the-middle attacks?

Encrypting data in transit is an effective countermeasure against man-in-the-middle (MITM) attacks. In these types of attacks, an unauthorized third party intercepts and potentially alters the communication between two parties without their knowledge. By implementing encryption during data transmission, even if the data is intercepted, it remains unreadable and secure. This ensures that sensitive information such as passwords, credit card numbers, or personal details remain protected from unauthorized access and manipulation.

While backing up data offsite, reviewing log data, and using block data storage are important aspects of overall data security management, they do not directly address the risk posed by MITM attacks. Offsite backups help ensure data recovery in case of loss, reviewing logs can provide insights into suspicious activities, and block storage pertains to how data is stored rather than the protection of data in transit. Therefore, encryption of data while it is being transmitted is the most relevant and effective method to mitigate the risks associated with man-in-the-middle attacks.
