How can sensitive data from Telemetry in Application Insights be protected and made accessible through encryption/decryption?

edit

Sensitive data from Telemetry in Application Insights can be protected and made accessible through encryption/decryption by following these steps:

1. Define which fields in the telemetry data contain sensitive information.

2. Use a secure encryption algorithm such as AES-256 to encrypt the sensitive data.

3. Store the encryption key securely, such as in Azure Key Vault, and restrict access to only authorized users.

4. When telemetry data is collected, encrypt the sensitive data before it is transmitted and stored in Application Insights.

5. When accessing the telemetry data, decrypt the sensitive data using the aforementioned encryption key.

6. To ensure that the decryption process is secure, it is important to implement proper access controls and authentication mechanisms.

7. It is critical to monitor and audit access to sensitive data to detect any potential unauthorized access.
