Identity Foundations: Start with the Right Core
Note: This is general information and not legal advice.

Executive Summary
- Security: identity is the most common attack path (phishing, token theft, admin takeover).
- Operations: consistent access patterns reduce “BYOD/workgroup/free-for-all” drift.
- Scale: clean onboarding/offboarding and role-based access prevents future rewrites.
- Multi-Factor Authentication (MFA) everywhere (phishing-resistant for admins where possible).
- Least-privilege admin roles with auditability (no shared admins).
- Device posture is defined (managed vs unmanaged) and enforced for sensitive access.
- Logs exist, are reviewable, and can be exported if needed.
Choosing an IdP: Google, Microsoft, Okta, and others
Many organizations start with what they already bought (Google Workspace or Microsoft 365). That can work well. In other cases—complex app portfolios, multi-tenant requirements, higher assurance authentication, or mergers—adding a dedicated IdP (e.g., Okta) can make sense.
The goal isn’t “pick the fanciest IdP.” The goal is an IdP you can operate cleanly: consistent MFA, clean admin model, lifecycle automation, and logs that support investigations.
- Good fits: the IdP you can enforce consistently across workforce apps, devices, and admin access.
- Not great fits: tools that require constant exceptions, or where key governance/logging features are locked behind plans you won’t buy.
Non-negotiables (regardless of vendor)
MFA that resists modern phishing
- Baseline: require MFA for all users.
- Admins: require phishing-resistant methods where possible (FIDO2/WebAuthn, device-bound options, passkeys with the right controls).
- Reduce prompt fatigue: avoid “approve push” as the only method.
Admin model that won’t explode later
- Separate admin accounts: don’t admin from daily-driver accounts.
- Least privilege: delegate by task, minimize super/global admins.
- Break-glass: keep emergency access accounts protected and excluded from risky policies.
Device posture + access rules
- Define “managed”: what qualifies (MDM enrollment, disk encryption, screen lock, OS version).
- Apply it where it matters: sensitive apps/data require stronger posture than low-risk apps.
Lifecycle automation (joiners/movers/leavers)
- Provisioning: role/group-based access and automated app provisioning where possible (SCIM is common).
- Offboarding: disable accounts, revoke sessions/tokens, transfer ownership, and remove SaaS access. See: Onboarding & Offboarding Playbook.
Logging & investigations (critical for response)
Identity logs should answer: who signed in, from where, to what, and what changed. At minimum, ensure you can review:
- Admin actions (policy changes, role grants, MFA method changes)
- Sign-in events (success/failure, risk signals if available)
- OAuth/app consent events (new app access / tokens)
If you need longer retention or centralized investigations, route identity logs to your logging platform.
How N2CON approaches identity foundations
- Vendor-neutral first: we design around outcomes and operating model, then map it to the right platform(s).
- Secure-by-default: policies are staged, tested, and monitored (not “flip the switch and hope”).
- Built to scale: role-based access and lifecycle automation so growth doesn’t break IT.
Common Questions
What is an Identity Provider (IdP) and why does it matter?
An IdP is the system that manages user identities and authentication (sign-in) for your organization. It's the control plane for access—how users sign in, how devices are trusted, how admins operate, and how access is granted and removed. Getting identity right early prevents expensive refactoring as you grow.
Should we use Google, Microsoft, or Okta as our IdP?
Many organizations start with what they already have (Google Workspace or Microsoft 365). Adding a dedicated IdP like Okta makes sense for complex app portfolios, multi-tenant requirements, or higher assurance authentication. The goal is an IdP you can operate cleanly with consistent MFA, clean admin model, lifecycle automation, and useful logs.
What is phishing-resistant MFA and why should admins use it?
Phishing-resistant MFA methods (FIDO2/WebAuthn, device-bound passkeys) cannot be bypassed by attackers stealing authentication codes or tokens. For admin accounts with high-privilege access, these methods significantly reduce takeover risk compared to "approve push" or SMS codes.
What are the non-negotiables for identity security?
MFA for all users (phishing-resistant for admins), separate admin accounts with least privilege, defined device posture requirements (managed vs unmanaged), lifecycle automation for joiners/movers/leavers, and logs that support investigations.
What identity logs should we capture for investigations?
At minimum: admin actions (policy changes, role grants, MFA method changes), sign-in events (success/failure, risk signals), and OAuth/app consent events (new app access and tokens). Route identity logs to your logging platform if you need longer retention or centralized investigations.
