Identity and Access Architecture
Conditional Access and Zero Trust Policies
Identity and access architecture is where Entra ID becomes the clean source of truth for who exists in your environment, what they do, and what they should be able to touch. Instead of letting identities, groups, and permissions grow organically over years of tickets and one‑off changes, we rebuild the structure so accounts flow from the right systems, groups reflect real roles and responsibilities, and access is granted because of clear rules rather than history or guesswork.
Design an Entra tenant and identity model that maps directly to your actual organization: business units, departments, locations, roles, and partner types.
Normalize naming standards for users, groups, and admin accounts so they are human‑readable, searchable, and consistent across cloud and on‑prem directories.
Integrate authoritative sources such as HR or identity governance tooling so joiners, movers, and leavers are created, updated, and removed automatically.
Separate security groups, Microsoft 365 groups, and dynamic groups with clear patterns for when each should be used, reducing random group sprawl.
Define role‑based access patterns where groups represent job functions and responsibilities, making it possible to assign access by role instead of per user.
Align license assignment with roles and groups so people receive the right Microsoft 365, Intune, and security capabilities as part of onboarding, not via manual exceptions.
Establish standards for admin and service accounts, including naming, scoping, and where they live (cloud‑only, synced, or on‑prem only).
Document identity flows between on‑prem AD, Entra ID, HR systems, and SaaS apps so it’s always clear where identities are created and how they propagate.
Implement guardrails to prevent direct assignment of permissions to individual users where groups or roles should be used instead.
Build reusable patterns for internal users, external collaborators, vendors, and partners so each identity type has a defined way of being invited, managed, and removed.
Introduce regular reviews of group membership, high‑privilege roles, and critical application assignments so identity and access stay aligned with reality over time.
Conditional Access and Zero Trust are where Microsoft Entra ID stops being “just a login” and becomes the policy engine that decides who gets access, from which device, under what conditions. Instead of treating every sign‑in the same, we design a layered model where user risk, device state, location, and app sensitivity all influence the final decision, so low‑risk everyday work stays smooth while high‑risk scenarios trigger stronger controls or are blocked outright.
Build Conditional Access policies that evaluate user risk, device compliance, network location, sign‑in behavior, and resource sensitivity together.
Require MFA and compliant, encrypted devices for high‑value assets such as admin portals, finance systems, sensitive SharePoint sites, and core line‑of‑business apps.
Treat admins, executives, contractors, and external partners as distinct risk profiles with different policy sets instead of one flat set of rules.
Enforce Zero Trust principles by verifying explicitly on every access attempt, never trusting the network alone, and always assuming breach when designing controls.
Use sign‑in and device signals from Entra and Intune to block or challenge access from risky locations, anonymous proxies, or suddenly unusual user behavior.
Apply session controls to limit what risky sessions can do (for example, allow web access but block downloads, copy/paste, or printing).
Implement step‑up authentication for sensitive actions and high‑impact operations so stronger verification only appears when the risk justifies it.
Integrate app protection and device compliance policies so unmanaged or non‑compliant endpoints get restricted access or browser‑only experiences.
Continuously review policy effectiveness using sign‑in logs and access reports, tuning rules to reduce noise while keeping strong guardrails in place.
Establish a regular governance cadence so new applications, new user groups, and new threat patterns are quickly reflected in your Conditional Access and Zero Trust design.
Device‑ and App‑Aware Access with Intune
Device- and app-aware access with Intune is where Entra ID stops trusting only who the user is and starts caring deeply about what they are using to connect and what data they are trying to touch. Instead of assuming every laptop or phone is equal, we tie access to real device health: encryption status, OS version, jailbreak/root state, threat protection posture, and the presence of required controls. Intune becomes the telemetry and enforcement engine for endpoints, and Entra ID uses that telemetry to decide whether a session is fully allowed, restricted, or blocked outright. The result is that Exchange, OneDrive, SharePoint, Teams, and line‑of‑business apps are only reachable from healthy, policy‑compliant devices, while unmanaged or risky endpoints are automatically pushed into safer, browser‑only or read‑only experiences rather than having to rely on “honor system” security.
Define Intune device compliance policies that cover encryption (BitLocker/FileVault), secure boot, password/biometric configuration, OS version minimums, jailbreak/root detection, and security tooling requirements.
Feed Intune compliance state directly into Entra ID Conditional Access so non‑compliant devices are either challenged, restricted, or blocked before they ever reach sensitive resources.
Require healthy, encrypted, and up‑to‑date endpoints as a baseline for accessing Microsoft 365 services such as Exchange Online, OneDrive for Business, SharePoint Online, Teams, and core SaaS applications.
Use app protection (MAM) policies to protect corporate data inside Office, Outlook, Teams, and line‑of‑business mobile apps, even when those apps run on personally owned phones and tablets.
Separate corporate and personal data on mobile endpoints so a remote wipe or retirement action can surgically remove company information without touching the user’s photos, messages, or personal apps.
Implement device configuration profiles that standardize Wi‑Fi, VPN, certificates, browser settings, endpoint security baselines, and other critical controls across Windows, macOS, iOS/iPadOS, and Android.
Build conditional experiences such as full native access on compliant corporate devices, browser‑only access on semi‑trusted endpoints, and hard blocks on known‑bad or unknown device types.
Leverage Intune’s app deployment and update capabilities to keep critical security tools (EDR, VPN, configuration agents) present, configured, and current on every managed endpoint.
Use remediation scripts and proactive remediations to automatically fix common drift issues (e.g., disabled services, missing registry keys, misconfigured policies) before they cause access failures or security gaps.
Configure detailed reporting and dashboards that show compliance posture by platform, department, location, and ownership model (corporate vs. BYOD), giving both IT and security real visibility into endpoint risk.
Align Conditional Access and Intune policies so device and app requirements move together — when you tighten access to a sensitive app, the device standards are raised at the same time.
Provide clear, in‑product guidance and self‑service remediation steps so end users know exactly what action to take when a device is blocked or restricted, reducing helpdesk noise while keeping standards high.
