CCI-002080

The organization employs either an allow-all, deny-by-exception or a deny-all, permit-by-exception policy for allowing organization-defined information systems to connect to external information systems.

Implementation Guidance

The organization being inspected/assessed configures the information system to employ a deny-all, permit by exception policy for allowing any systems requiring external connectivity to connect to external information systems. For information system components that have applicable STIGs or SRGs, the organization being inspected/assessed must comply with the STIG/SRG guidance that pertains to CCI 2080. DoD has defined the information systems as any systems requiring external connectivity.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures the information system to employ a deny-all, permit by exception policy for allowing any systems requiring external connectivity to connect to external information systems. For information system components that have applicable STIGs or SRGs, the organization conducting the inspection/assessment evaluates the components to ensure that the organization being inspected/assessed has configured the information system in compliance with the applicable STIGs and SRGs pertaining to CCI 2080. DoD has defined the information systems as any systems requiring external connectivity.

Compelling Evidence

1.) Signed and dated SOP/TTP documenting the (reference exception to policy section) configuration of information systems to employ a deny-all, permit by exception policy for allowing any systems requiring external connectivity to connect to external information systems. 2.) Applicable STIG/SRG checks
