🛡️ Zero Trust Network

“Never Trust, Always Verify” for Users, Devices & Workloads

A Zero Trust Network (ZTN) assumes no implicit trust—not from your LAN, your WAN, your VPN, or the cloud edge.
Every connection is verified explicitly, granted least privilege, and re-verified continuously based on identity, device posture, app sensitivity, data classification, and context.
SolveForce implements Zero Trust as a system: identity + device + network + app policies unified, observability wired to SIEM/SOAR, and rollout done in safe rings with evidence.

🔐 Zero Trust Network Access (ZTNA) → ZTNA • ☁️ SASE → SASE • 🚪 NAC → NAC
🧩 Microsegmentation → Microsegmentation • 🔑 IAM / SSO / MFA → IAM

🎯 Outcomes (Why Zero Trust with SolveForce)

  • Least privilege everywhere— users get only the app they need; workloads talk only to the services they must.
  • Breach containment by design— microsegmentation + identity-aware policy stops lateral movement.
  • Better UX than legacy VPN— local, high-performance access via ZTNA/SASE POPs; no hair-pin to hubs.
  • Provable security— every decision logged; posture and access evidence shipped to SIEM; automation via SOAR.
  • Composable— works across LAN/WAN/cloud, Kubernetes/service mesh, OT/IoT, and remote work.

🧭 Scope (What We Put Under Zero Trust)

  • Human access — employees, contractors, third-parties via ZTNA/SASE. → ZTNA • SASE
  • Device posture — managed endpoints via MDM/UEM + EDR/XDR; unmanaged via restricted profiles. → MDM / UEM: Mobile & Endpoint Management for a Zero-Trust Enterprise • EDR / MDR / XDR
  • Workload-to-workload — mTLS/service identity (SPIFFE/SVID) + microsegmentation on DC, cloud, and K8s. → Microsegmentation
  • Edge entry — NAC (802.1X EAP-TLS) for wired/Wi-Fi; dynamic VLAN/ACL/SGT by posture. → NAC
  • Data controls — DLP labels, tokenization, encryption at rest/in transit; per-route egress policy. → DLP • Encryption
  • Identity — IAM/SSO/MFA, short-lived tokens, PAM for elevation; secrets from vault. → IAM • PAM • Secrets Management

🧱 Zero Trust Policy Model (Identity → Device → App → Data → Context)

Each request/session is evaluated across five lenses:

  1. Identity — user/service role & assurance (SSO/MFA, claims).
  2. Device posture — EDR/UEM healthy, disk encryption, OS min, cert present.
  3. Application — sanctioned SaaS, private app/API, admin plane risk tier.
  4. Data classification — PII/PHI/PAN/CUI → stronger controls (read-only, watermark, redact).
  5. Context — geo/ASN/time, session risk, change windows, behavior.

Outcome: allow (least privilege) → step-up (MFA/PAM) → isolate (read-only/RBI) → deny.

🧰 Architecture (How It Comes Together)

  • Access edge — SASE POPs enforce SWG/CASB/FWaaS/ZTNA; users attach to nearest POP. → SASE
  • Campus/LAN — NAC with 802.1X EAP-TLS + posture; dynamic VLAN/ACL/SGT; guest/contractor isolation. → NAC
  • Workloads — service mesh or host agents enforce mTLS & per-service policy; microsegmentation for L3-L7. → Microsegmentation
  • WAN/Cloud — SD-WAN steers by SLOs; private on-ramps (Direct Connect/ExpressRoute/Interconnect) for deterministic paths. → SD-WAN • Direct Connect / Cloud On-Ramps
  • Control plane — IAM + policy engine; SIEM correlates; SOAR executes contain/rollback; keys in KMS/HSM. → IAM • SIEM / SOAR • Key Management / HSM

🛠️ Reference Patterns (Choose Your Fit)

VPN Services

Workforce Access (VPN Replacement)

  • ZTNA per app; posture-based access; SASE inspection for web/SaaS; legacy VPN only for niche tunnels. → ZTNA • SASE

IAM

Contractor / Third-Party

  • Clientless ZTNA; read-only/watermarks; session recording for admin operations; time-boxed accounts.

PAM

Privileged Admin

  • PAM elevation + ZTNA; session recording; hardware keys (FIDO2) for step-up MFA; break-glass with short TTL. → PAM

Hybrid Cloud

Workload ↔ Workload (DC/Cloud/K8s)

  • mTLS service identity + policy (L7 methods/paths); microseg rules compiled from intents; no flat networks. → Microsegmentation

IoT Solutions

OT/IoT & Campus Edge

  • NAC profiling; function-based enclaves; per-device allowlists; ZTNA for jump hosts; NDR for anomalies. → NAC • NDR

📐 SLO Guardrails (Targets You Can Measure)

KPI / SLOTarget (Recommended)
ZTNA attach (p95)≤ 1–3 s to first byte
SASE POP attach (regional p95)≤ 20–40 ms
Policy decision time (p95)≤ 100–300 ms
NAC auth (802.1X p95)≤ 2–5 s
Microseg false-deny rate (post-tune)≤ 1–2%
Identity step-up success (MFA p95)≤ 3–5 s
Evidence completeness (Sev-1/2)100% (decisions, posture, changes)

SLO breaches trigger SOAR actions (relax/reroute/rollback) and incident tickets. → SIEM / SOAR

🔒 Security Controls (Concrete & Enforceable)

  • Allow only ICMPv6 essentials (ND/PMTUD) and required ports; block everything else by default. → IPv6
  • TLS/mTLS everywhere; certs via PKI; keys in HSM/KMS; short-lived tokens; no plaintext secrets. → PKI • Key Management / HSM • Secrets Management
  • DLP & tokenization for sensitive data; WAF/Bot at boundaries; DDoS stance. → DLP • WAF / Bot Management • DDoS Protection
  • Logging & retention: access, posture, policy hits → SIEM with WORM options; SOAR for automated containment. → SIEM / SOAR

📊 Observability & Evidence

  • Identity— SSO/MFA results, group claims, PAM elevations.
  • Device— EDR/UEM posture, quarantine events.
  • Network— NAC admits/CoA, microseg enforces/denies, ZTNA attach times, SASE verdicts.
  • App/Data— DLP hits, WAF blocks, API allow/deny, service-mesh policy logs.
    Dashboards link decisions → users/devices/workloads; monthly reports shipped to security & compliance.

🧭 Migration Blueprint (No-Surprise Rollout)

1) Define protect surface — crown-jewel apps/data; map transactions and users/roles.
2) Identity & device posture — SSO/MFA groups; MDM/UEM + EDR baselines. → IAM • MDM / UEM: Mobile & Endpoint Management for a Zero-Trust Enterprise • EDR / MDR / XDR
3) Access edge — pilot ZTNA/SASE for one app group; retire broad user VPN for those users. → ZTNA • SASE
4) Campus edge — enforce 802.1X/NAC; dynamic segmentation; guest/contractor isolation. → NAC
5) Workload microseg — intent → policy; simulate → enforce; mTLS service identity. → Microsegmentation
6) Data controls — DLP labels; tokenization; key custody posture. → DLP • Key Management / HSM
7) Operate — SIEM dashboards; SOAR playbooks; quarterly tune-ups & drills. → SIEM / SOAR

📜 Compliance Mapping (Examples)

  • PCI DSS— least privilege, segmentation, encryption, logging & 911 evidence for voice endpoints.
  • HIPAA— minimum necessary, identity & posture checks, immutable logs.
  • ISO 27001— A.9/A.12/A.16 access/ops/incident controls.
  • NIST 800-53/171— AC/IA/AU/CM families; Zero Trust aligned.
  • CMMC— enclave separation, per-session authorization, audit exports.

Artifacts (policies, decisions, session logs) are exportable for auditors.

Key terms in plain language

Open a term for a concise explanation of language used on this page.

SD-WAN

Software-defined wide area networking. It manages multiple connections and chooses paths based on application needs, performance, and policy to improve resilience and control.

VPN

A virtual private network creates an encrypted connection across another network, commonly allowing remote users or offices to access private resources securely.

Cloud Computing

Computing resources—such as applications, servers, storage, or databases—delivered from remote infrastructure and scaled as requirements change.

Software as a Service (SaaS)

Software accessed as an online service instead of being installed and maintained entirely on the customer’s own computers or servers.

Cybersecurity

The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.

Zero Trust

A security model that does not automatically trust a user or device because of its location. Access is continuously verified and limited to what is necessary.

SASE

Secure Access Service Edge combines networking and security capabilities in a cloud-delivered architecture so users and locations can receive consistent policy wherever they connect.

Identity and Access Management (IAM)

The systems and policies that determine who a user is, what resources they may access, and how that access is authenticated and reviewed.
