Narrative (how this runs—without drift)
1) Purpose & posture
- Objective: Sovereign, high-availability WAN for embassies/bases/HQ/mobile units with classified & controlled-unclassified separation, and global reach across 200+ countries.
- Operating model: Zero-Trust by default, defense-in-depth, and jurisdiction-aware routing & storage.
2) Edge & transport (syntax of the network)
- SD-Branch/SD-WAN at every site with dual underlays: DIA/MPLS + LTE/5G or SATCOM (VSAT/LEO/MEO/GEO).
- VRFs segregate: Classified / Controlled-Unclass / Admin / Guest / Contractor.
- ZTP brings new sites online predictably.
- Global transport fabric mixes terrestrial (DIA/MPLS/Waves/IX) with satellite & cellular; policy-based steering prefers lowest latency; auto-failover in <60s.
3) Zero-Trust perimeter (semantics preserved)
- SASE/SSE POPs enforce: ZTNA (user+device+context), SWG/CASB (SaaS control), FWaaS/DLP/RBI.
- Geo-pin & data-sovereignty: traffic and storage pinned to compliant regions automatically.
4) Compute destinations (classified + cloud)
- Sovereign colo/DC: compartmentalized enclaves, HSM/KMS, PAM, SIEM; optional air-gaps for highly classified workloads.
- Cloud on-ramps (Direct Connect/ExpressRoute/Interconnect) to gov/sovereign regions with private routing.
5) Mission applications & data plane
- Mission apps (intel, C2, GIS, CAD) live in enclaves; enterprise apps (ERP/IdP/email) live in controlled zones; analytics/AI in pinned cloud/data lakes.
- Inter-agency exchange uses API gateways with policy-backed schemas; all transfers signed & logged.
6) Security controls (trust zones)
- Identity-centric access (IdP + MFA + device posture).
- Microsegmentation between enclaves and VRFs; east-west NDR for lateral-movement detection.
- Key custody via HSM/KMS, with crypto-erasure for emergency sanitization.
7) Resilience & failover (grammar under stress)
- Path diversity: DIA/MPLS + LTE/5G + SATCOM.
- Application-aware steering: Mission flows prioritized; guest/contractor throttled during incidents.
- Active-active across sovereign DCs; cloud region failover pre-staged; RTO/RPO targets enforced.
8) Telemetry, ops & compliance (pragmatics)
- AIOps observability bus: logs/metrics/traces from edge → NOC/SOC for anomaly detection and SLA proofs.
- ITSM/CMDB as source of truth (sites, circuits, enclaves).
- Frameworks: NIST 800-53, FedRAMP/FISMA; CJIS/ITAR/EAR/GDPR as applicable; immutability for audit trails.
9) Reference KPIs (mission-grade)
- Availability: ≥99.99% core; Failover: <60 s; Global latency: ≤150 ms inter-region;
- MTTD/MTTR: <15 min triage / <2 h containment; Policy conformity: >98%.
