Discussion

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/SOA will require the use of TLS mutual authentication (two-way/bidirectional).

Check

Open the Fly Server console in a browser and note the port number in the URL.

Fly Server uses ports 20100 and 20101 by default for Manager and Agent internal communication.

If the ports used are organization-defined to be in use by another system, this is a finding.

Fix

Configure the internal communication ports for Fly Server Manager and Agent. - Install Fly Server Manager and Agent. - Set Manager Access URL and Internal Communication Port setting, set to ports that are not organization-defined to be in use by another system.
