SQLI-22-016500 - The SQL Server Mirroring endpoint must use AES encryption.

Information

Information can be unintentionally or maliciously disclosed or modified during preparation for transmission, including, for example, during aggregation, at protocol transformation points, and during packing/unpacking. These unauthorized disclosures or modifications compromise the confidentiality or integrity of the information.

Use of this requirement will be limited to situations where the data owner has a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process.

SQL Mirroring endpoints support different encryption algorithms, including no-encryption. Using a weak encryption algorithm or plaintext in communication protocols can lead to data loss, data manipulation, and/or connection hijacking.

Solution

Run the following to enable encryption on the mirroring endpoint:
ALTER ENDPOINT <Endpoint Name>
FOR DATABASE_MIRRORING
(ENCRYPTION = REQUIRED ALGORITHM AES)
