Microsoft Defender: work without advanced hunting (PLUG-4744) - #163
Customers without advanced hunting on device data (Defender for Endpoint Plan 1, Defender for Business, Defender for Office 365 only), or who grant only some permissions, can't add the Microsoft Defender data source today. Setup fails on the advanced hunting check and the device import (Failed to resolve table or column expression named 'DeviceInfo').
This PR lets each part of the plugin work on its own:
Setup checks and device import are optional. A missing permission or licence shows a warning saying what it affects, instead of blocking setup.
Readable errors. Graph errors are turned into plain guidance: a missing advanced hunting table (named, so typos are visible) with a hint about device-data licences, missing permission or licence (with the role Graph names and the read-only permission each part needs), or wrong credentials.
Dashboards grouped by what they need. A new Overview (Secure Score, high severity incidents and alerts) replaces Cockpit and works on any licence. Everything that needs advanced hunting moves to an Advanced Hunting folder.
High severity by default. Overview and Incidents tiles ask Microsoft Graph for high severity only, so they load on tenants with thousands of alerts and incidents. Customers can copy a tile and change the Severity parameter.
Alerts data stream. Adds a Service Source column (for example, Office 365 vs Endpoint) and fixes the "New" status filter, which Graph rejected.
Docs and descriptions. Each data stream and the README say which permission and licence it needs.
Version1.0.4 → 1.1.0. Authentication is unchanged.
Held back: vulnerability data without advanced hunting. It needs a second API token, which isn't possible until the platform supports it. The work is in the branch history; reverting b00b609 restores it.

🧪 Testing
All manual tests pass on 3aaefca; a short re-check of 43458fd and 414479c is pending. Tested in a browser between 2026-11-06 and 2026-11-09 on SquaredUp DEV (tenant Les Bleus) against a real Defender tenant with 11 devices, over 5,500 active alerts and over 2,490 incidents. Three app registrations were used: all roles, everything except ThreatHunting.Read.All, and ThreatHunting.Read.All only. Covered: setup with each permission set and with a wrong secret, every dashboard and data stream, readable errors, an in-place upgrade from 1.0.4 with customer tiles and a monitor, and load times on a busy tenant. 43458fd and 414479c fix three CodeRabbit findings (read-only permission hint on every 403; Device Exposure State counting every device and labelling unassessed ones); all were checked by query on Les Bleus and are listed for a UI re-check. Not tested: a real Plan 1 tenant (validation pending with the customer Complea). Four known issues remain, none blocking.
Full list of tests, what wasn't tested, and known issues
Setup and permissions
All roles: all four checks pass, Connected, 11 devices imported. Edit, Test and Save keep it Connected
Without ThreatHunting.Read.All: the advanced hunting check is a warning, setup completes, the device import ends as warnings with 0 devices, status Connected
ThreatHunting.Read.All only: the Alerts, Incidents and Secure Score checks warn and each names its permission; 11 devices imported
Wrong client secret: all four checks warn and each ends "If every check fails, check your tenant ID, client ID and secret." The data source can be added; the import ends as a warning with 0 objects. With the correct secret it recovers: Connected, 11 devices in about 10 s
Readable errors
Missing permission: errors name the role Graph asks for (for example ThreatHunting.Read.All on Advanced Hunting tiles, SecurityAlert.Read.All on alert tiles)
Read-only hint: every 403 ends "Read-only permissions are enough: alerts need SecurityAlert.Read.All, incidents SecurityIncident.Read.All, Secure Score SecurityEvents.Read.All, and advanced hunting ThreatHunting.Read.All." (checked by query on 43458fd, see re-check below)
Missing table: a typo such as DeviceInfos returns the named-table message; invalid KQL returns Microsoft's syntax error
Dashboards, all roles
Overview: all 8 tiles load in about 11 s with no warnings. High severity counts (9 incidents, 35 alerts) match the alerts list (35 rows); alerts by Service and by Category; Secure Score current and history
Incidents: loads in about 8 s with no warnings. Active and Unassigned counts (9 and 9); by Status shows counts (active 9, redirected 1); Top 10 Active by Priority Score shows one bar per active incident, highest first, matching the list; the list shows all 10 high severity incidents
Opening Overview and Incidents again straight away: no rate-limit warning
Advanced Hunting (Threat Detections, Devices Health): every tile loads in about 20 s
Device pages (Device Status, Vulnerabilities, Recommendations): scoped to the selected device (2 devices compared)
Dashboards, reduced permissions
Without ThreatHunting.Read.All: Overview and Incidents load normally. Advanced Hunting tiles show an error naming ThreatHunting.Read.All
ThreatHunting.Read.All only: Advanced Hunting dashboards load. Overview and Incidents tiles show errors naming the missing permission
Data streams
Alerts: no filter; Status New, In Progress and Resolved; Severity High and Low; Last Activity Time; new Service Source column present
Incidents: Severity High and Medium, Status Active and Resolved, several timeframes; every row matches the filter (this tenant has no resolved incidents, so Resolved returns "No data")
Deploy reports "Updated … from v1.0.4 to v1.1.0"; the data source keeps its name, stays Connected with 11 devices
Customer-built tiles keep working. A saved Alerts "Status = New" tile that failed on 1.0.4 ('newAlert' is not a valid enumeration type constant) now returns data
Re-index: same 11 devices, no duplicates; device-scoped streams still work
A monitor on an Incidents tile created on 1.0.4 keeps its state through the upgrade and keeps evaluating every 15 minutes
Load on a busy tenant
Active high severity alerts: 35 rows in 0.2 s. All active alerts timed out after 15 s at 4,000 rows, which is why Overview shows high severity only
High severity incidents: 10 rows in one request, well under Graph's limit of 20 incident requests a minute
A larger Alerts page size was tried and dropped: it still timed out at 4,000 rows, because the cost is the amount of alert data, not the number of requests
To re-check in the UI on 414479c
Devices Health, all roles: Device Exposure State shows one bar per exposure level covering all 11 devices (currently None 6, Medium 3, Low 2), coloured None green, Low blue, Medium amber. Devices with no exposure level would show as "No data" in grey (this tenant has none). The query already returns these values
Devices Health, without ThreatHunting.Read.All: Device Exposure State shows an error like its neighbours, not "No data". The query already returns the readable 403
Overview, ThreatHunting.Read.All only: Explore data on Active High Severity Alerts shows Graph's roles followed by the read-only line
Not tested
A real Plan 1 tenant. We can't change our licence. Validation is pending with the customer Complea, who reported the DeviceInfo error
Resolved incidents. The test tenant has none, so the Resolved filter could only be checked for "No data"
Known issues (none blocking)
Wrong secret shows Connected. A wrong client secret leaves the data source green "Connected" with 0 objects, and the import steps show the platform's raw token 401. Accepted: no single check can be required without blocking least-privilege setups. Raised with the platform team.
High severity only. Customers who want medium or low copy a tile and change its Severity parameter; on very busy tenants those may still time out or hit Graph throttling.
Top 10 chart labels. Long incident names are cut off with no tooltip, so incidents whose names start the same look alike; the list below shows the full names. Incidents with the same score have no fixed order.
Platform: error text is hidden. Tiles show only "The API returned an error" or "Something went wrong"; the readable message is in Explore data.
⚠️ Breaking changes
Does this PR introduce any breaking changes?
No
Out-of-the-box dashboards change (Cockpit becomes Overview, hunting dashboards move to a folder, Overview and Incidents show high severity only). Customer-created dashboards are not touched, and no data stream is removed or renamed. One behaviour change: a wrong client secret no longer blocks saving; it shows a warning on every check instead.
📚 Documentation
Documentation updated
✅ Checklist
This PR changes a single plugin only
No secrets or credentials included
Plugin, datastream and UI naming follow SquaredUp guidelines
Tenants without advanced hunting on device data (Defender for Endpoint
Plan 1, Defender for Business, Defender for Office 365 only) and tenants
that grant only some permissions could not add the data source, because
the alerts and advanced hunting validation steps were required and the
device import failed.
- Make every config validation step optional, with messages that name
the missing permission or licence and what stops working
- Mark the device import steps optional so the import still completes
- Replace Cockpit with an Overview dashboard that works on any licence:
Secure Score, active incidents and active alerts
- Move every dashboard that needs advanced hunting into an Advanced
Hunting folder, including a new Threat Detections dashboard built from
the Cockpit hunting tiles
- Add the Service Source column to the Alerts data stream
- Document which permission and licence each capability needs

Walkthrough
The Microsoft Defender plugin updates permission checks, data-stream descriptions and error handling, and dashboard content. It adds an Overview dashboard, revises the Incidents dashboard, and updates Advanced Hunting dashboards and documentation.
Changes: Microsoft Defender plugin
Layer / File(s)
Summary
Permissions and capability configuration plugins/MicrosoftDefender/v1/configValidation.json, plugins/MicrosoftDefender/v1/indexDefinitions/default.json, plugins/MicrosoftDefender/v1/docs/README.md, plugins/MicrosoftDefender/v1/metadata.json
Permission checks and device-import steps are optional. Configuration messages and the README describe capability requirements. Plugin metadata changes the version to 1.1.0 and updates the description.
Data-stream requirements and error handling plugins/MicrosoftDefender/v1/dataStreams/*.json, plugins/MicrosoftDefender/v1/dataStreams/scripts/errorHandling/microsoftGraphApi.js
Data-stream descriptions specify permission and licence requirements. Streams use a shared script for Graph error handling. The alerts stream maps the UI status new to the API value new and adds the serviceSource metadata field.
The default manifest replaces Cockpit with Overview. Overview adds Secure Score tiles and history, incident and alert counts and charts, and a table of active high-severity alerts.
Incident tiles and the incidents table now focus on high-severity incidents. The dashboard adds a status chart and a top-10 list ordered by descending priorityScore.
The dashboards use the Advanced Hunting folder. Threat Detections has tiles for malware and antivirus, persistence and privilege escalation, application control, and exploits. Devices Health adds a device exposure state tile. The Advanced Hunting manifest lists dashboard items.
Merge Risk: Minimal · up to 41447
Setup and device import are made optional when advanced hunting is unavailable. No merge-blocking regression was established.
Security architecture risk: Low · up to 1d36d
The update supports partial-capability setups without increasing the application's declared permissions or changing its authentication model. Existing registration guidance can still lead administrators to grant broader access than Defender needs; no PR-specific increase in that exposure was established.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — If an administrator follows the linked guide's broader permission list and consents directory or SharePoint read access, misuse of that application's credentials can expose tenant data beyond Defender. The relevant scope follows the application's consented grants, not the dashboards selected in the plugin. This grant route already exists in the base documentation.
Security Findings and Attack Paths
observed — Both retained findings concern README line 19 directing administrators to the generic Microsoft 365 registration guide. Supplied verification identifies permissions including Directory.Read.All and Sites.Read.All in that guide. The README's instruction to grant only selected permissions is meaningful counterevidence, but does not explicitly replace the guide's permission list. The findings remain relevant without establishing a PR-introduced authority expansion.
Trust Boundaries and Controls
inferred — Capability validation probes Graph reads or a DeviceInfo hunting query. Making those probes optional relaxes onboarding acceptance, not token issuance or Graph permission enforcement. A missing capability can produce warnings, but the inspected change supplies no mechanism to obtain data without the application's corresponding authority.
Hardening Proposals
proposed — Use Defender-specific registration guidance that explicitly substitutes selected capability permissions for the generic guide's permission list. Include guidance for reviewing and removing unnecessary existing grants while accounting for applications shared with other integrations.

…ting
Vulnerability data was only reachable through advanced hunting, so
Defender for Business and least-privilege customers could not see it.
The Defender for Endpoint API serves it with Vulnerability.Read.All, but
needs a token for its own audience, separate from the Graph token.
- Add a pre-request script that reroutes "mde/" endpoint paths to the
Defender for Endpoint API and authenticates them with a second client
credentials token, cached in state. Graph requests are untouched.
- Add the unscoped Vulnerability Exposures data stream, with a server
side severity filter
- Add an optional vulnerability management validation step
- Add a Vulnerability Exposure dashboard
- Document the WindowsDefenderATP permission and licence

…ript
Live testing showed every Graph request failing once the pre-request
script was added, with the same credentials that work on 1.0.4. The
script returned early for Graph requests, which likely left the platform
without the request's url and headers.
The script now always runs to the end and issues both tokens itself
(authMode none, the pattern the other script-authenticated plugins use),
which also removes any dependency on whether the built-in OAuth2 header
is added before or after the script.

Claude-Session: https://claude.ai/code/session_01M7jt3x4WCc6X5fWJrBDAVB
Live testing showed the platform blocks the pre-request script from
fetching login.microsoftonline.com ("not allowed by this data source").
login.microsoft.com is an official Entra ID alias of that authority for
the public cloud, and shares the microsoft.com domain with the Graph
base URL, which is the pattern the Redstor plugin relies on to reach its
token host.

…lity errors
Live testing on an upgraded data source found:
- The Alerts stream's "New" status option sent 'newAlert', which Graph
rejects ("not a valid enumeration type constant"), so any tile
filtering on it failed, including the new Overview tiles. The option
now sends 'new', and saved tiles that still send 'newAlert' are mapped
to 'new'.
- Data sources keep the settings they were saved with, so one added on
1.0.4 has no pre-request script and its "mde/" requests reach Graph.
Vulnerability streams now explain how to fix that (save the data
source), and name the missing permission on a 401 or 403.

… critical
On a 49-device test tenant, critical and high exposures came to 27,550
rows: four Defender for Endpoint API pages per tile, with seven tiles
loading at once. Tiles took minutes and several failed. Critical alone
is about 3,000 rows, a single page, so every tile now asks for critical
exposures only. The data stream still accepts any severity.

…h errors
- Data stream descriptions now name the permission or licence each
stream needs, so users see it in the stream picker before a tile fails.
- Graph streams share an error script that turns common failures into
plain guidance. A missing device table (as reported by a Plan 1
customer: "Failed to resolve table or column expression named
'DeviceInfo'") explains that the licence has no advanced hunting on
device data; a 403 says to grant the missing permission and keeps
Graph's message, which names the role; a 401 points at the
credentials.

…ced hunting
The second API token for the Defender for Endpoint API relied on a
pre-request script, which won't be approved until the platform supports
that case. This release goes out without it:
- Remove preRequest.js and restore the built-in OAuth2 configuration
from 1.0.4, so existing data sources need no re-save.
- Remove the Vulnerability Exposures data stream, its validation step
and error script, and the Vulnerability Exposure dashboard.
- Remove the WindowsDefenderATP permission guidance from the README.
Everything else in 1.1.0 stays. Reverting this commit restores the
feature once the platform is ready.

From review:
- The Overview alert tiles limited alerts to those created in the last
30 days, so alerts open for longer were missing from "Active Alerts".
They now use no timeframe, filtered on status only, like the Incidents
tiles.
- The README no longer presents "no devices imported" as a definite
licence problem; Defender may simply have no named devices.

The other three setup checks already say to check the tenant ID, client ID

same, so a wrong secret reads consistently across all four warnings.

Tenants with thousands of active alerts or incidents timed out on the
Overview alert tiles (15 s for 4,000 of 5,500+ alerts) and hit Graph's
20 calls a minute limit on incident tiles. Filtering to high severity on
the API side brings the test tenant down to 35 alerts in 0.2 s and 10
incidents in one request.
- Overview: alert and incident tiles show active high severity only;
single-severity bar charts become counts

Round 2 testing found both Incidents charts plotted the priority score
value instead of counting incidents (by Status showed "active 56" for 9
active incidents). The charts had no aggregation, which was also the
case on 1.0.4.
- High Severity Incidents by Status: counts incidents per status
- By Priority Score becomes Top 10 Active High Severity Incidents by
Priority Score: one bar per incident, highest score first
- A 403 that names no role (Secure Score does this) now ends with the
permission each part of the plugin needs

From the CodeRabbit review of 3aaefca:
- Every 403 now ends with the read-only permission for each part of the
plugin. Graph lists read and write roles side by side for alerts and
incidents, which could lead an admin to grant write access.
- Device Exposure State counts every device with an advanced hunting
query, like the other Devices Health tiles. It counted imported
devices with a scope capped at 500, and showed "No data" instead of
an error without advanced hunting. Colours now match exposure levels.

- Line 504: Update the DeviceInfo query to map missing or empty ExposureLevel
values to a named “No data” category before the final summarize. Update the
chart’s color rule to match that category, preserving the existing handling of
Low, Medium, High, and other values.

Devices Defender hasn't assessed have an empty ExposureLevel, which the
Device Exposure State chart showed as a bar with no label or colour.
They now show as "No data" in grey, and None (no exposure) is green.

📋 Summary
Customers without advanced hunting on device data (Defender for Endpoint Plan 1, Defender for Business, Defender for Office 365 only), or who grant only some permissions, can't add the Microsoft Defender data source today. Setup fails on the advanced hunting check and the device import (
Failed to resolve table or column expression named 'DeviceInfo').This PR lets each part of the plugin work on its own:
1.0.4→1.1.0. Authentication is unchanged.Held back: vulnerability data without advanced hunting. It needs a second API token, which isn't possible until the platform supports it. The work is in the branch history; reverting
b00b609restores it.🔗 Related issue(s)

Does this PR introduce any breaking changes?
Out-of-the-box dashboards change (Cockpit becomes Overview, hunting dashboards move to a folder, Overview and Incidents show high severity only). Customer-created dashboards are not touched, and no data stream is removed or renamed. One behaviour change: a wrong client secret no longer blocks saving; it shows a warning on every check instead.
