Description |
---|
Enforcing allowed information flows based on metadata enables simpler and more effective flow control. Metadata is information used to describe the characteristics of data. Metadata can include structural metadata describing data structures (e.g., data format, syntax, and semantics) or descriptive metadata describing data contents (e.g., age, location, telephone number). Information flow control regulates where information is allowed to travel within a network and between hosts, as opposed to who is allowed to access the information. Information flow enforcement mechanisms, such as cross domain solutions, compare metadata attached to the data and respond appropriately (e.g., allow, block, quarantine, or alert administrator). |

If the ALG is not part of a CDS, this is not a finding. Verify that policy filters exist that enforce traffic flow inbound and outbound across the controlled security boundary based on organization-defined metadata. If the ALG does not control traffic based on organization-defined metadata, this is a finding. |
