Entra ID security review guide

Microsoft Entra ID is the control plane for Microsoft 365, Azure, SaaS access, privileged administration, device-based access, and identity security. A practical Entra ID security review helps confirm that administrators are protected, Conditional Access is working, risky sign-ins are investigated, app permissions are governed, guest users are reviewed, and evidence is available for leadership or audit review.

Why it matters

Turn Entra ID from a default directory into a governed security control plane

Many Microsoft 365 security issues start with weak identity governance: excessive administrators, inconsistent MFA, legacy authentication, unmanaged app permissions, stale guests, unreviewed Conditional Access policies, or poor monitoring.

A strong Entra ID security review combines configuration checks with operational evidence. The goal is to understand what is configured, whether it is working, where exceptions exist, and which issues should be remediated first.

Practical rule: Every Entra ID review should prove who has privileged access, how sign-ins are protected, which apps can access data, how guests are governed, and how identity events are monitored.

Entra ID security evidence to collect

Tenant overview including licensing, domains, sync model, break-glass accounts, admin contacts, security defaults, and key security settings.
Privileged role evidence including Global Administrator, Privileged Role Administrator, Security Administrator, Exchange Administrator, SharePoint Administrator, app administrators, and eligible or active assignments.
Authentication evidence including MFA coverage, passwordless readiness, authentication methods, legacy authentication exposure, self-service password reset, and break-glass exceptions.
Conditional Access evidence including policies, assignments, exclusions, report-only policies, device compliance conditions, named locations, session controls, and emergency access testing.
Monitoring evidence including sign-in logs, audit logs, risky users, risky sign-ins, impossible travel, admin changes, app consent events, and alert review process.
Governance evidence including app registration review, enterprise app permissions, guest access, access reviews, lifecycle process, exceptions, and remediation tracking.

Review scope

What an Entra ID security review should cover

Privileged access

Review privileged roles, permanent assignments, emergency accounts, admin MFA, PIM readiness, and separation of duties.

Authentication

Check MFA, passwordless methods, legacy authentication exposure, SSPR, authentication strengths, and user registration.

Conditional Access

Validate policy coverage, exclusions, report-only policies, device compliance, risky sign-in controls, and testing.

Identity monitoring

Review sign-in logs, audit logs, risk events, alert process, admin changes, and evidence retention.

Applications and consent

Review app registrations, enterprise apps, delegated permissions, application permissions, owners, secrets, and consent workflow.

Guests and lifecycle

Review guest users, external collaboration settings, sponsors, access reviews, inactive accounts, and removal evidence.

Review matrix

Entra ID security review control matrix

Area	What to verify	Questions to answer	Evidence
Privileged roles	Whether administrators are limited, protected, monitored, and reviewed.	Reduce standing privilege, require MFA, review role assignments, and document emergency access.	Role export, admin MFA status, break-glass validation, and review decision log.
MFA and authentication	Whether users and admins have strong sign-in protection.	Close MFA gaps, remove weak methods, enforce modern authentication, and review passwordless options.	Authentication method report, Conditional Access policies, sign-in logs, and exception list.
Conditional Access	Whether access policies cover users, apps, risk, device state, and locations without risky exclusions.	Test and tune policies, remove unsafe exclusions, document break-glass exclusions, and monitor failures.	Policy export, test results, sign-in impact, and emergency access validation.
Identity Protection	Whether risky users and risky sign-ins are detected, reviewed, and remediated.	Configure risk policies, review events, investigate patterns, and document response actions.	Risk event report, investigation notes, remediation tickets, and closure evidence.
Apps and consent	Whether applications have excessive permissions, stale secrets, or unclear ownership.	Review app owners, permissions, credentials, consent grants, and remove unneeded access.	App inventory, permission export, owner approval, and removal evidence.
Guest access	Whether external users still need access and have accountable sponsors.	Run guest reviews, remove stale access, review collaboration settings, and track exceptions.	Guest export, sponsor decisions, access review report, and removal record.

Step-by-step review

Entra ID security review runbook

Collect tenant baseline

Record tenant domains, licensing, sync model, admin contacts, break-glass accounts, security defaults, and key identity settings.

Review privileged access

Export role assignments, identify permanent administrators, validate MFA, confirm emergency access, and document reduction opportunities.

Validate sign-in protection

Review MFA coverage, authentication methods, legacy authentication exposure, risky sign-ins, and Conditional Access results.

Inspect applications and consent

Review app registrations, enterprise apps, owners, permissions, secrets, certificates, consent grants, and stale applications.

Review guests and lifecycle

Export guest users, identify stale or unsponsored guests, review collaboration settings, and document access removal.

Report and remediate

Prioritize findings, assign owners, create remediation tickets, track exceptions, and provide executive-ready evidence.

Common risks

Common Entra ID security review findings

Too many standing administrators

Excessive permanent privilege increases the blast radius of credential theft or admin mistakes.

Conditional Access gaps

Missing policies, broad exclusions, weak location trust, or untested report-only policies can leave access exposed.

Weak authentication methods

Inconsistent MFA coverage, weak methods, or legacy authentication can undermine identity security.

Unreviewed app permissions

Apps with broad delegated or application permissions can create hidden data access risk.

Stale guest access

External collaborators may retain access after projects, vendor work, or client engagements end.

Poor monitoring evidence

Without sign-in, audit, risk, and remediation evidence, identity security is hard to manage or prove.

FAQ

Entra ID Security Review FAQ

What is an Entra ID security review?

It is a structured review of Microsoft Entra ID identity controls, including privileged access, authentication, Conditional Access, monitoring, app permissions, guest access, and remediation evidence.

How often should Entra ID be reviewed?

High-risk areas such as privileged roles, risky sign-ins, guest access, and app permissions should be reviewed regularly, with deeper reviews at least annually or after major changes.

What logs are important for an Entra ID review?

Sign-in logs, audit logs, risky user events, risky sign-ins, app consent events, admin changes, and Conditional Access results are important evidence sources.

Should app registrations be included?

Yes. App registrations and enterprise apps can hold powerful permissions, secrets, certificates, and consent grants that should be reviewed.

Can IT Perfection help with Entra ID security reviews?

Yes. IT Perfection can help collect evidence, review configurations, tune controls, document findings, and support remediation.
