Which method is effective for securing sensitive data?

The most effective way to secure sensitive data is through a combination of multiple methods, which is why selecting "all of the above" is the correct choice. Each method contributes uniquely to the overall security of data.

Encryption is crucial because it transforms sensitive information into a format that is unreadable without the appropriate decryption key. This ensures that even if someone unauthorized gains access to the data, they cannot interpret it without the means to decrypt it.

Access control measures play a vital role by regulating who can access the data and what actions they can perform on it. By implementing strict access permissions, organizations can minimize the risk of unauthorized access or data breaches.

Regular audits serve to assess and ensure that security measures are being properly followed and are effective. They help identify vulnerabilities and ensure compliance with security policies, allowing for timely remediation of any issues found.

Thus, utilizing encryption, access controls, and conducting regular audits creates a comprehensive approach to data security, protecting sensitive information from various threats and vulnerabilities.
