Networks and data

The MA CP uses Red, Gray, and Black terminology to classify data security levels
Red Network - Contains only unencrypted classified data
Gray Network - Contains encrypted classified and unclassified data
Black Network - Contains unencrypted unclassified data
Red, Gray, and Black refer to the level of protection applied to the data

Red Networks

Red Networks are controlled by the solution owner or a trusted third party.
EUDs access Red Networks through two layers of nested encryption.
Access to classified services is granted after successful IPsec connection establishment.
The Inner VPN Gateway terminates the Inner layer of IPsec encryption for VPN EUDs.
TLS-Protected Servers can be used for TLS EUDs, providing a TLS-Protected Server that terminates the Inner layer of encryption and acts as a proxy to Red Services.
If using user client certificate authentication on the Red Network, the Inner VPN Gateway option is recommended over the Inner TLS-Protected Server option.
The Inner TLS-Protected Server option is viable for services using TLS Server Authentication only or clear text.
TLS certificates used to connect to the Inner TLS-Protected Server should be non-person entity (NPE) certificates.
The Inner TLS-Protected Server option is also suitable for replicated services at the gray/red boundary, where user certificates are allowed but NPE certificates are preferred.
SRTP traffic for EUDs can be terminated by a VoIP Gateway/Border Controller located between the Gray Firewall and the Inner Firewall.
Desktop phones in the Red Network are not included in the Solution Boundary.
The Red Network can only communicate with an EUD through the MA solution if both operate at the same security level.
The Gray Firewall can detect failures of the Outer VPN Gateway by logging dropped packets not associated with an Inner Encryption Component.
If the Inner Encryption Component fails, the Outer VPN Gateway provides sufficient encryption to prevent immediate exposure of classified data to a Black Network.
If both the Outer and Inner Gateways fail simultaneously, classified data from the Red Network can be sent to a Black Network without adequate encryption.
The CSfC Program emphasizes the importance of diversity in implementation between the layers of the solution.
The two ways to achieve diversity are by using components produced by different manufacturers or by using components from the same manufacturer that have been independently verified by the NSA.
Customers wishing to use products from the same manufacturer in both layers must confirm that NSA has accepted the manufacturer’s claims before implementing their solution.
