How can you protect data stored in the cloud from unauthorized copying?

1. Set stronger user passwords

2. Use encryption

3. Limit access to certain users

4. Conduct regular security audits

The correct answer is: Use encryption

Using encryption is a highly effective method to protect data stored in the cloud from unauthorized copying. Encryption transforms readable data into an unreadable format through the use of algorithms and keys. When data is encrypted, even if an unauthorized user gains access to it, they will be unable to understand or utilize the information without the proper decryption key. This adds a significant layer of security, as it safeguards the data by making it inaccessible in its original form, thereby preventing unauthorized copying or exposure. In the context of cloud storage, where data may be distributed across various locations and potentially accessed by multiple users, encryption ensures that sensitive information remains secure, regardless of its physical storage environment. It also helps comply with regulatory requirements concerning data protection, reinforcing the importance of keeping data secure in a cloud setting. While the other choices, such as setting stronger user passwords, limiting user access, and conducting regular security audits, do contribute to an overall security strategy, they do not provide the direct and robust protection that encryption offers against unauthorized access and copying of data.
