The NSX Distributed Firewall must enforce approved authorizations for controlling the flow of information within the network based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.

Description
Information flow control regulates where information is allowed to travel within a network. The flow of all network traffic must be monitored and controlled so it does not introduce any unacceptable risk to the network infrastructure or data. Information flow control policies and enforcement mechanisms are commonly employed by organizations to control the flow of information between designated sources and destinations (e.g., networks, individuals, devices) within information systems. Examples of information flow control restrictions include keeping export controlled information from being transmitted in the clear to the Internet or blocking information marked as classified but is being transported to an unapproved destination. ALGs enforce approved authorizations by employing security policy and/or rules that restrict information system services, provide packet filtering capability based on header or protocol information and/or message filtering capability based on data content (e.g., implementing key word searches or using document characteristics).

Check Text ( C-69577r1_chk )
Verify the rules necessary to enforce approved authorizations for logical access to information and system resources by employing identity-based, role-based, and/or attribute-based security policies are configured, enabled and the respective "Applied to" category is configured if appropriate. Log into vSphere Web Client with credentials authorized for administration, navigate to Networking and Security >> Firewall >> Configuration tab >> General. Expand rule sections as necessary to view rules. If there are no rules configured to enforce authorizations, this is a finding.
