The application server must authenticate all network-connected endpoint devices before establishing any connection.
Device authentication requires unique identification and authentication that may be defined by type, by specific device, or by a combination of type and device. Device authentication is accomplished via the use of certificates and protocols such as SSL mutual authentication. Device authentication is performed when the application server is providing web services capabilities and data protection requirements mandate the need to establish the identity of the connecting device before the connection is established.
Configure the application server to perform mutual authentication of network-connected endpoint devices before the connection is established.
Review application server documentation, application data protection requirements, and configuration to ensure the application server provides an SSL mutual authentication capability and the authentication is completed before the connection is fully established. If data protection requirements require mutual authentication and the application server is not configured to meet this requirement, this is a finding.
