To allow PII to be shared securely without compromising security, which action should be taken regarding DLP policies?

Whitelisting the application with specific PII is a strategic approach to adhering to data loss prevention (DLP) policies while maintaining security effectively. This action involves explicitly permitting certain applications to handle personally identifiable information (PII) under controlled conditions. By specifying which applications are allowed to process and share PII, organizations can mitigate the risk of unauthorized access and ensure that only trusted processes interact with sensitive data.

This method also enables organizations to maintain oversight and control over how PII is used, potentially incorporating other security measures such as encryption or monitoring within the whitelisted applications. This provides a layered security approach to managing sensitive information, ensuring compliance with relevant regulations and decreasing the likelihood of data breaches.

In contrast, allowing all PII or all ports used by the application could lead to significant vulnerabilities, as it does not restrict access or usage and could expose sensitive data to unauthorized entities. Encrypting PII within the application is a good security practice, but it does not inherently control which applications can access or share the data, nor does it limit the scope of potential exposure. Therefore, whitelisting offers a more tailored and responsible approach to managing and sharing PII securely.
