Deployment & Architecture

Deployment Model: Government Cloud (FedRAMP boundary)

Zscaler Government Cloud operates within a FedRAMP-authorized boundary. CUI can be processed within the authorization scope, but contractors must verify their specific use case falls within the system's security boundary as documented in the SSP.

Configuration Checklist

  1. 1ISSO must update the System Security Plan to document Zscaler Government Cloud as the primary internet gateway for CUI traffic processing, including data flow diagrams per NIST 800-171 control CM-8.
  2. 2Network administrators configure secure IPSec tunnels from all CUI-processing network segments to route traffic exclusively through Zscaler Government Cloud infrastructure.
  3. 3ISSO establishes DLP policies within Zscaler to detect and protect CUI markings during web traffic inspection, addressing NIST 800-171 control AC-4 information flow enforcement.
  4. 4System administrators integrate Zscaler with existing Active Directory or PKI infrastructure to ensure proper user authentication for CUI access per AC-2 account management controls.
  5. 5Security team configures Zscaler's advanced threat protection to scan all downloads for malware before reaching CUI-processing endpoints, supporting SI-3 malicious code protection.
  6. 6ISSO documents incident response procedures for Zscaler-detected threats in the Incident Response Plan, ensuring compliance with NIST 800-171 control IR-4.
  7. 7Network administrators establish bandwidth prioritization rules to ensure mission-critical CUI traffic receives adequate performance through Zscaler infrastructure.
  8. 8ISSO configures audit logging integration between Zscaler and contractor SIEM to meet NIST 800-171 control AU-6 audit review requirements for CUI access monitoring.
  9. 9Contracts officer updates DFARS 252.204-7012 flow-down language to reflect Zscaler Government Cloud as an approved CUI processing boundary in subcontractor agreements.
  10. 10Security team validates authorization boundary documentation includes Zscaler Government Cloud connections and updates POA&M entries for any implementation gaps.
