What is a key recommendation for handling data on removable media?

Always encrypting files on removable media is a key recommendation for handling data securely. This practice helps protect sensitive information from unauthorized access, especially if the device is lost, stolen, or accessed by individuals who shouldn't have authorization. Encryption converts the data into a format that is unreadable without the correct decryption key, ensuring that even if the removable media falls into the wrong hands, the data remains secure.

The other recommendations while useful, do not fully address the risks associated with removable media. For instance, while deleting files after use can help clear outdated or unnecessary data, it does not prevent unauthorized access to data that has not been securely stored or transmitted in the first place. Using removable media solely for temporary storage limits its functionality and might not encompass scenarios where such media is necessary for long-term data transfer. Limiting access to external devices can help reduce risks, but it does not mitigate the need for strong encryption, especially when sensitive data is involved. Overall, encryption is a fundamental step that enhances data security significantly.
