🔑 IAM

Identity & Access Management for a Zero-Trust Enterprise

Identity & Access Management (IAM) is the control plane for who can access what, when, and from where—with proof. SolveForce designs and operates IAM so every request is least-privilege, auditable, and friction-minimized through Single Sign-On (SSO) and Multi-Factor Authentication (MFA). The result: stronger security, cleaner user experience, and compliance that stands up to scrutiny.

Where IAM fits in the SolveForce model:
🔒 Security (Semantics) → Cybersecurity • 🛡️ SASE → SASE • 🔐 ZTNA → ZTNA
🧑‍💻 Device trust → MDM / UEM • 🛡️ EDR/XDR → EDR / MDR / XDR
🧰 Privileged control → PAM • 🔑 Key trust → PKI • 🧪 Evidence → SIEM / SOAR

🎯 Outcomes (What a good IAM program delivers)

  • Least-privilege by default — users get only what they need, only when they need it.
  • Fewer passwords, fewer prompts — SSO + adaptive MFA lower friction while raising assurance.
  • Verified devices — access requires healthy, enrolled endpoints (EDR/UEM posture).
  • Federated access — one identity across SaaS, IaaS, and private apps.
  • Provable compliance — complete evidence trails for audits (who/what/when/why/approval).

🧱 IAM Building Blocks (Spelled out)

  • Identity Provider (IdP) — your source of truth (cloud IdP or directory + sync).
  • Directory — users, groups, service accounts; attribute store for policy.
  • SSO (Single Sign-On) — SAML 2.0 / OIDC federation to SaaS and private apps.
  • MFA (Multi-Factor Authentication) — possession/biometric factors (TOTP, WebAuthn/FIDO2, push), with adaptive risk.
  • Policy Engine — conditional access rules (who + device + location + risk → allow/step-up/deny).
  • Provisioning — automated Joiner/Mover/Leaver (JML) flows into apps (SCIM/Graph APIs).
  • Credential & Secrets Hygiene — password policies, passkeys, service secrets rotation, and key custody.
  • Audit & Analytics — login events, anomalies, failed attempts, admin actions → SIEM/SOAR.

🔄 The Identity Lifecycle (JML: Joiner → Mover → Leaver)

  1. Joiner — create identity from HRIS, assign role-based access, enroll device and MFA, issue keys/certs.
  2. Mover — change role → auto-add/remove app entitlements; time-box elevated access; log approvals.
  3. Leaver — immediate disable, revoke tokens, wipe devices (if corporate), rotate shared secrets, archive evidence.

Enforce least-privilege at each step; automated de-provisioning closes the biggest breach window.

🧠 Policy Model (Identity → Device → App → Data → Context)

IAM decisions consider five lenses before granting access:

  1. Identity — user, group/role, assurance level (SSO/MFA).
  2. Device posture — EDR/UEM health, OS version, disk encryption, certificate presence. → MDM / UEM • EDR / MDR / XDR
  3. Application sensitivity — admin consoles vs. regular apps; sanctioned SaaS vs. private apps.
  4. Data classification — DLP policies for PII/PHI/PAN; tokenization where needed. → DLP
  5. Context — geolocation/ASN, time/day, impossible travel, session risk.

Outcome: allow → step-up (MFA/PAM) → isolate (read-only/RBI) → deny.
→ Admin elevation via Privileged Access Management (PAM). See PAM

🔐 SSO & Federation (SAML / OIDC) — make one identity go everywhere

  • SAML 2.0 — established federation for many enterprise SaaS apps.
  • OIDC (OpenID Connect) — modern OAuth-based login for web/mobile.
  • SCIM — automated user/app provisioning (create/update/deactivate).
  • App catalog — publish sanctioned apps; block unsanctioned via CASB/SWG. → SASE

Best practice: use group/attribute-based access control (ABAC), not one-off entitlements.

🧰 MFA that users actually tolerate

  • Factors: TOTP apps, push, WebAuthn/FIDO2 (phishing-resistant), SMS (fallback only).
  • Adaptive: require stronger MFA for admin actions, new devices, high-risk geo, or stale posture.
  • Session control: remembered devices for low-risk apps; short TTL for sensitive apps.
  • Break-glass: hardware tokens for execs/IT; out-of-band process for IdP outages (logged).

🧾 Credential & Secrets Hygiene

  • Passkeys / WebAuthn — passwordless where supported; reduce phishing risk.
  • Password policy — length > complexity; block known-bad lists; rotate only on compromise.
  • Service accounts — remove shared creds; issue short-lived tokens; rotate secrets; vault them.
  • Certificates & Keys — device/user certs via PKI; manage lifecycle, revocation, and escrow. → PKI • Key Management / HSM

🧭 Reference Architectures

A) Workforce SSO + Adaptive MFA (SaaS-first)

  • IdP centralizes SSO; SCIM to provision; adaptive MFA on risk; CASB governs SaaS sessions; all logs → SIEM.

B) ZTNA for Private Apps (Contractors/Partners)

  • Clientless ZTNA + SSO; posture-based rules; read-only/watermark for BYOD; session recording for admin access. → ZTNA • SASE

C) Admin & Break-Glass

  • Dedicated admin identities; PAM for elevation; hardware FIDO keys; emergency bypass with strict audit. → PAM

D) Hybrid Cloud & On-Prem

  • Directory sync to cloud IdP; Kerberos/LDAP apps proxied via app gateways; OIDC migration plan.

MetricTarget (Regional)Notes
SSO login → token≤ 1–2 s typicalCache metadata; keep IdP close to users
MFA step-up≤ 3–5 s (push/WebAuthn)Prefer FIDO2 for speed + anti-phish

IdP availability≥ 99.99% (SaaS)Dual regions; DR runbook

Monitor via IdP analytics, synthetics (login/MFA flows), and RUM for user-facing apps. → NOC Services

🔒 Compliance Mapping (examples)

  • SOC 2 / ISO 27001 — logical access control, change logs, evidence trails.
  • PCI DSS — unique IDs, MFA for admin access, least privilege, log retention.
  • HIPAA — unique user identification, emergency access, automatic logoff, audit controls.
  • NIST 800-53/171 — AC/IA controls; password policies; credential management; session controls.
  • CMMC — access control (AC), identification & authentication (IA) domains.

All IAM events stream to SIEM/SOAR for correlation, alerts, and audit packs. → SIEM / SOAR

🧪 Migration Plan (From brittle logins to coherent IAM)

  1. Inventory — apps (SaaS/private), protocols (SAML/OIDC/LDAP/Kerberos), user stores, and groups.
  2. Choose IdP backbone — cloud IdP or hybrid; directory sync strategy; multi-region availability.
  3. Federate priority apps — SSO + SCIM; retire stored passwords; enable adaptive MFA.
  4. Harden admin access — separate admin identities; PAM, hardware keys, session recording. → PAM
  5. Roll ZTNA — publish private apps via connectors; remove broad network VPN; apply posture rules. → ZTNA
  6. Close gaps — replace shared service creds with tokens/short-lived certs; vault leftovers.
  7. Prove it — run synthetics for login flows; ship logs; baseline SLOs and CSAT.

📊 Metrics That Matter

  • Login Success Rate (per app, per region)
  • MFA Success & Fall-back Rate (push/WebAuthn/SMS)
  • De-provisioning Time (leaver to token revoke)
  • Dormant Accounts (30/60/90 days)
  • Privilege Creep Index (entitlements vs. role)
  • Phishing Resilience (FIDO/WebAuthn adoption %)

Dashboards roll up to security, IT ops, and compliance leadership for one version of truth.

🧰 Integrations & Runbooks

  • ITSM — approvals for privileged access; change tickets for policy edits.
  • HRIS — JML automation; terminations feed immediate disable.
  • E-mail & Chat — targeted MFA prompts, login health notices.
  • SEIM/SOAR — automated containment on suspicious authentications. → SIEM / SOAR
  • Device Trust — quarantine non-compliant endpoints; require remediation. → MDM / UEM • EDR / MDR / XDR

✅ Pre-Engagement Checklist

  • 👥 Users, roles, contractors/partners, BYOD policy.
  • 🔐 MFA factors allowed (TOTP, FIDO2, push; SMS as fallback only).
