What method should an organization consider for protecting sensitive customer information stored on its servers that is currently not accessed or processed?

The chosen method of encryption for protecting sensitive customer information stored on servers is effective because it transforms the data into an unreadable format using cryptographic algorithms. This ensures that even if unauthorized individuals gain access to the stored data, they would not be able to comprehend it without the proper decryption key. This layer of security is particularly crucial for sensitive customer information, as it safeguards personal and financial data from potential breaches, even when the data is not actively being accessed or processed.

Encryption not only protects data at rest but also ensures compliance with regulations that require the safeguarding of sensitive information. It is a robust method that applies even when the data is not in use, making it a top choice for organizations looking to implement sound security practices for their customer information.

Other methods like data masking and tokenization provide different types of data protection, but encryption offers a comprehensive solution that secures data in its stored state. Access controls are also important, but they primarily restrict who can access data rather than providing protection if access is obtained. Thus, while each method has its own merits, encryption stands out as the most effective choice in this scenario for its strong ability to secure inactive sensitive data.
