What ensures zero knowledge encryption privacy in SailPoint?

• A. The encryption key is stored within the application
• B. The private encryption key is not accessible to SailPoint
• C. The key is shared among users
• D. Public keys are available for access

Answer: (B)

Zero knowledge encryption is a cryptographic principle where the service provider, in this case SailPoint, does not have access to the user's private encryption key. This ensures that even if the data is stored or processed on the service's infrastructure, the service provider cannot decrypt the user's data due to the lack of access to the necessary key. Therefore, the private encryption key remains solely in the hands of the user, providing strong privacy protections since the provider cannot gain knowledge of the plaintext data, regardless of their access to the encrypted data.

In this context, storing the encryption key within the application would create a risk of access since the application could potentially decrypt data if needed. Sharing the key among users would undermine the security model, as it would allow others to access encrypted data that is meant to be private. Lastly, the availability of public keys for access does not secure the confidentiality of data; while public keys can be used for encryption, they don't provide the strong privacy assurances that zero knowledge encryption aims to deliver.
