feat(intune): add macOS compliance and enrollment checks (MT.1214-MT.1217)#2147DanielLystad wants to merge 16 commits into
Conversation
Adds four macOS security checks: - MT.1214 macOS compliance policy requires System Integrity Protection - MT.1215 Gatekeeper restricts app download locations - MT.1216 macOS compliance policy requires a Defender machine risk score level - MT.1217 macOS LAPS is configured on Automated Device Enrollment profiles MT.1214-MT.1216 share Get-MtMacOsCompliancePolicy, which fetches macOS compliance policies once and carries assignment state, since an unassigned compliance policy is never evaluated against a device. MT.1217 uses Get-MtMacOsEnrollmentProfile. macOS LAPS is configured on the ADE enrollment profile rather than in a settings catalog policy, so it needs the two-hop depOnboardingSettings to enrollmentProfiles query. The helper deliberately never retains adminAccountPassword. Test IDs reserved on maester365#697.
Invoke-MtGraphRequest surfaces a failed Graph call as a non-terminating error with a null result. Collected with @(), that becomes a single element with no properties, so a 403 was indistinguishable from an empty tenant. Left unhandled, MT.1214-MT.1217 would return $false on a permission error, reporting a security finding caused only by the caller's lack of access. deviceManagement/depOnboardingSettings is especially prone to this because it is gated by Intune RBAC in addition to the Graph scope. Both internal helpers now return $null when a request yields no usable data, and all four checks report NotAuthorized instead of a false negative. The catch blocks also map 401/403 to NotAuthorized.
…e links Every table row linked to the same compliance list blade, which reads as a per-object deep link but is not one. Intune has no stable per-policy deep-link format (it requires a policyType discriminator that varies by platform), so the policy name is now plain text with a single link to the relevant blade beneath the table.
… consistency The repo capitalizes acronyms in function names (Test-MtIntuneLAPSConfiguration, Test-MtIntuneASRRules), so the macOS LAPS check should match. Grepping for LAPS now finds both the Windows and macOS checks.
…andling Adds 32 unit tests in powershell/tests/functions/Test-MtMacOsSecurity.Tests.ps1 covering the pass, fail, unassigned-policy, empty-tenant and not-authorized branches of MT.1214-MT.1217, plus both internal helpers. Writing them surfaced a real defect. PowerShell unrolls collections on output, so an empty List returned by the helpers arrived at the caller as $null - which the callers treat as 'could not read'. A tenant with genuinely zero macOS compliance policies or enrollment profiles would therefore have been reported as NotAuthorized instead of failing the check. Both helpers now emit their result with -NoEnumerate so an empty collection stays distinguishable from $null. The unit tests also cover MT.1217 end to end without tenant access, which matters because deviceManagement/depOnboardingSettings is gated by Intune RBAC and returns 403 for accounts lacking the enrollment programs permission. One test asserts that adminAccountPassword never appears on the object returned by Get-MtMacOsEnrollmentProfile.
An unrecognised gatekeeperAllowedAppSource or advancedThreatProtectionRequired- SecurityLevel was rendered as 'Not configured' / 'Not evaluated', which claims a setting is absent when it is actually set to a value the test does not know about. Graph enums gain values over time, so this was a question of when rather than if. The known 'unset' values (notConfigured, unavailable, notSet) are now mapped explicitly and anything unrecognised falls through to its raw value, so the reader sees what is really configured. Adds seven adversarial unit tests covering unrecognised enum values, an empty display name, a zero rotation period, and multi-policy mixed-state cases. 39 unit tests total, all passing.
macOS is a product name with fixed official casing, and the Graph resources these checks query spell it macOSCompliancePolicy and depMacOSEnrollmentProfile. The Microsoft-authored zerotrustassessment repo, which is the upstream source of these specs, also uses macOS / MacOS in its identifiers. Maester has no prior macOS identifier to follow and is inconsistent on acronyms (Test-MtIntuneLAPSConfiguration and Test-MtIntuneASRRules, but Test-MtIntuneRbacGroupsProtected), so matching the API surface is the more defensible tiebreaker.
PSScriptAnalyzer flags New-* helpers with PSUseShouldProcessForStateChanging- Functions. The unit tests added in maester365#2123 use Get-TestDynamicGroup and Get-TestCaPolicy, so Get- both silences the rule and matches precedent. PSScriptAnalyzer now reports zero findings at Error, Warning and Information level across all seven new files.
…tation Verifying MT.1217 against a real tenant surfaced a gap. A macOS enrollment profile that provisions a local administrator account with no password rotation configured gives every device enrolled through it a static local administrator password that Intune never rotates. That is the precise risk the check exists to catch, but it was only visible as 'Not configured' in the table and was not called out when a different profile satisfied the check. The pass branch now warns explicitly. Adds a unit test mirroring the observed tenant shape: a compliant default profile alongside one with a static password and one with no admin account at all.
A tenant can have one enrollment profile that provisions a rotated admin account and another that provisions an admin account with no rotation. Reporting that as a clean pass gives false assurance: the second profile hands every device enrolled through it a static local administrator password. The check now returns Investigate rather than a plain pass when a compliant profile coexists with one that provisions a static password, following the pattern used by MT.1196. A tenant where every profile is sound still reports a clean pass. Observed on a real tenant: three profiles, one compliant, one with an admin account and no rotation, one with no admin account at all.
Four of five comparable internal helpers upstream use try/catch, so the absence here reads as an omission. It is deliberate: the calling check maps 401/403 to NotAuthorized, and swallowing the exception at helper level would lose the status code and turn a permission problem into a false security finding. Stated in the comment-based help so a reviewer does not have to infer it.
Comparing against Test-MtBitLockerFullDiskEncryption, the established shape for an Intune check result is an intro line, a table, a verdict, and at most one warning. Three changes bring these checks into line: - Drop the admin centre link from the result. No existing Intune check puts a portal link there; they live in the companion .md, which already has them. - Drop the macOS LAPS re-enrollment scope note from the result. It is static text and is already a Scope limitation section in the companion .md, so repeating it in every run was duplication. - Shorten the two data-driven notes to one sentence each. Also fixes the placement of 'Well done.', which was prepended to the whole result and so appeared before the table rather than on the verdict sentence. It is now omitted entirely when the result is flagged for investigation, since congratulating a tenant while warning about a static password contradicts itself.

… token request Addresses review feedback on maester365#2147. Get-MtMacOSEnrollmentProfile guarded the depOnboardingSettings request against a failed call, but not the per-token enrollmentProfiles request. A failure there was filtered out silently by the id check, leaving a partial or empty list, so Test-MtMacOSLAPSConfiguration would report a failed control instead of a skip. Two regression tests cover it: a valid token whose profile request fails must return $null, and a token holding only iOS profiles must return an empty list. Also strengthens the null assertions throughout the unit tests. Should -BeNullOrEmpty is satisfied by an empty collection as well as by $null, so it could not distinguish the two states these tests exist to separate. Reverting the fix now produces exactly one failure, on the intended test. Replaces two legacy Apple support URLs with their canonical form, and adds a contributors.yml entry.

The Two regression tests cover it: a valid token whose profile request fails must return Checking that also turned up a weakness in my own assertions: Apple support URLs (nitpick): applied.

Following maester365#2143 and maester365#2144, which broadened MT.1178 and MT.1123 to detect policies authored in the settings catalog, MT.1215 had the same gap in the other direction. It only read the macOS compliance policy, so a tenant that enforces the com.apple.systempolicy.control payload but has no Gatekeeper compliance rule failed the check despite genuinely restricting app sources. The macOS endpoint protection template is deprecated, so settings catalog is where new Gatekeeper configuration is authored, and that will be the common case over time. Adds Get-MtMacOSGatekeeperEnforcement, which flattens the group setting collection to reach enableassessment and allowidentifieddevelopers. The check now passes if an assigned policy of either kind restricts app sources, and the result table carries a Source column distinguishing the two, matching the presentation in maester365#2144. A policy that disables Gatekeeper assessment does not count. Renamed the check to 'Ensure Gatekeeper restricts macOS app download locations', since it is no longer limited to compliance policies. 49 unit tests. Verified against a tenant holding both a compliance rule and an assigned settings catalog enforcement policy; both appear with their source.

…tekeeper key Addresses review feedback on maester365#2147. Get-MtMacOSGatekeeperEnforcement guarded the policy list request against a failed call but not the per-policy settings and assignments requests. A failed settings read left no setting instances, so the policy was skipped silently and an enforced tenant looked unconfigured. Both requests now apply the same guard. allowidentifieddevelopers was coerced to $false when the setting instance was absent, which reported 'Enforced: Mac App Store only' - a stricter posture than the policy actually enforces. An MDM payload only applies the keys it contains, so an omitted key leaves the device's existing setting untouched. It is now reported as $null and rendered as 'assessment on, identified developers not specified'. Reverting either fix produces exactly two failures on the intended tests. Also fixes two problems in the new tests themselves: the Describe-level default mock for Get-MtMacOSGatekeeperEnforcement shadowed the real function in that helper's own tests, so it is now scoped to the contexts that exercise MT.1215; and a mock filter used '*configurationPolicies?*', where ? is a single-character wildcard that also matched the per-policy settings and assignments URIs. 52 unit tests.

📑 Description
Adds four macOS checks from the Intune test spec list:
Apple coverage today is the four token-expiry checks (MT.1092-MT.1095). Nothing reads
deviceCompliancePoliciesoutside an internal Defender helper, and nothing readsdepOnboardingSettingsat all, so there is no overlap with the Zero Trust assessment port.Note that SIP cannot be enforced by MDM — it is toggled from Recovery on the device — so MT.1214 checks that it is required as a compliance condition, which is what makes a Mac with SIP disabled non-compliant and blockable by Conditional Access. macOS LAPS is likewise not Windows LAPS: it lives on the ADE enrollment profile rather than in a settings catalog policy, which is why MT.1217 needs a different endpoint.
