TCMax must be configured to prohibit or restrict using organization-defined functions, ports, protocols, and/or services, as defined in the Ports, Protocols, and Services Management Category Assurance List (PPSM CAL) and vulnerability assessments.

Authenticity protection provides protection against man-in-the-middle attacks/session hijacking and the insertion of false information into sessions. Application communication sessions are protected using transport encryption protocols, such as TLS, which provides web applications with a means to be able to authenticate user sessions and encrypt application traffic. Session authentication can be single (one-way) or mutual (two-way) in nature. Single authentication authenticates the server for the client, whereas mutual authentication provides a means for both the client and the server to authenticate each other. This requirement applies to applications that use communications sessions. This includes, but is not limited to, web-based applications and service-oriented architectures (SOAs). This requirement addresses communications protection at the application session, versus the network packet, and establishes grounds for confidence at both ends of communications sessions in ongoing identities of other parties and in the validity of information transmitted. Depending on the required degree of confidentiality and integrity, web services/service oriented architecture (SOA) requires using TLS mutual authentication (two-way/bidirectional).

1. Using a Windows account of appropriate privileges to access the file system, open the file C:\ProgramData\Soaring Software Solutions\TCMax\Configuration Files\DatabaseConnections.xml. 2. Review the connection string attribute for Data Source. If the port specified in the Data Source is not approved by the PPSM CAL, this is a finding.

Configure the connection to use ports approved by the PPSM CAL.
