SV-94031r1_rule SQL Server Service Broker endpoint must utilize AES encryption.

Vulnerability discussion

Information can be either 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 Server Service Broker 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.

Check content

If the data owner does not have a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process, and the requirement is documented and authorized, this is not a finding. If SQL Service Broker is in use, run the following to check for encrypted transmissions:   SELECT name, type_desc, encryption_algorithm_desc FROM sys.service_broker_endpoints WHERE encryption_algorithm != 2 If any records are returned, this is a finding.

Fix text

Run the following to enable encryption on the Service Broker endpoint: ALTER ENDPOINT FOR SERVICE_BROKER (ENCRYPTION = REQUIRED ALGORITHM AES)

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
