The ALG that is part of a CDS, when transferring information between different security domains, must examine the information for the presence of organization-defined unsanctioned information.

| Description |
|---|
| Without the capability to examine information, there is no means to determine the presence of information not authorized for transfer. Information flow decisions based on unexamined data may allow unintended and unauthorized data flows and therefore risk the confidentiality of information and may also result in the unauthorized release (spillage) of information. Detection of unsanctioned information includes, for example, checking all information to be transferred for malicious code and dirty words. |

| If the ALG is not part of a CDS, this is not a finding. Verify the ALG when transferring information between different security domains, is configured to examine the information for the presence of organization-defined unsanctioned information. If the ALG is not configured to examine the information for the presence of organization-defined unsanctioned information when transferring information between different security domains, this is a finding. |
