Appgate Software-Defined Perimeter (SDP) is a Department of Defense (DoD)-approved authentication service. This Zero Trust solution provides secure access to DoD networks and associated data. Managed by the Platform One (P1) Cloud Native Access Point (CNAP) team, Appgate SDP provides a range of network security protections to include:
- Denying implicit trust to a single user, device, or application.
- Enforcing a verify then trust security approach to network access.
- Promoting Least Privilege, solely providing as-needed access to network resources.
P1 SSO also helps authenticate and authorize DoD network users. While you can browse IL2 (example: https://code.il2.dso.mil) without Appgate SDP access, you must – in some cases – use Appgate SDP to enter IL4+ environments such as https://code.il4.dso.mil. For IL5 access outside the NIPRNet boundary, you must also run compliance scripts.
The DoD uses Non-Classified Internet Protocol Router Network (NIPRNet) to manage unclassified information. If you use NIPRNet or NIPRNet VPN (such as Air Force Desktop Anywhere), you can access IL4 and IL5 without using Appgate SDP. DoD's P1 team requires that you use Appgate SDP if you do not use NIPRNet or NIPRNet VPN, as you cannot access IL4 or IL5 without using one of these options.
As customers, it is critical to understand that CNAP allows secure access to Game Warden-hosted solutions at IL4 and IL5. As a reminder, P1 CNAP manages Appgate.
The implementation of Appgate and Palo Alto firewalls provides DoD-approved solutions that meet security controls, as referenced in sections 5.10.1.x of the Cloud Computing Security Requirements Guide (Version 1, Release 4).
