Executive Brief
SaaS identity risk becomes manageable when identity, security, SaaS administration, endpoint, application, procurement, and business teams treat third-party access as one lifecycle. The objective is not to block every connected app or browser extension. It is to know what is connected, understand what access has been granted, confirm who owns the business purpose, detect meaningful change, and remove access that is no longer justified.
IETF RFC 9700 is the current Best Current Practice for OAuth 2.0 security. It updates the OAuth threat model and security advice based on deployment experience. The document is aimed at OAuth implementations rather than enterprise SaaS inventory, but its core security discipline supports a broader operating point: authorization should be designed and handled deliberately, not treated as a permanent side effect of sign-in. [1]
Build the Connected Access Inventory
Do not start with the question, “Which OAuth applications should we block?” Start with one critical SaaS service and map the access relationships it actually depends on. Capture third-party applications, OAuth grants, browser extensions, service integrations, service accounts or other non-human identities, users or groups, permission sets, host access, business purpose, approval route, owner, last-known use, and documented removal path.
Microsoft's admin-consent workflow demonstrates why approval evidence matters. Users who cannot grant required permissions can request administrator review; designated reviewers receive the request, evaluate it, and act on it. This is a Microsoft-specific workflow, but the operating pattern is useful: important access should have a requester, a reason, a reviewer, an explicit decision, and an expiry or review point. [2]
Worksheet 1. Connected Access Inventory and Dependency Canvas
|
Signal |
What to Capture |
Why It Matters |
|---|---|---|
|
Connected access |
Application or extension, SaaS service, OAuth client or integration identifier where available, user or service identity, affected resource, connection source. |
Shows what access relationship exists before a risk or removal decision is made. |
|
Permissions and reach |
Granted scopes or permissions, delegated or application context where applicable, browser API or host access, user or group coverage, resource or data reach. |
Distinguishes what the connected software can do from the business name shown in an app catalog. |
|
Business dependency |
Business purpose, workflow, team, criticality, process owner, downstream dependency, vendor or publisher, approved use case. |
Prevents access reviews from breaking legitimate operations simply because a permission appears broad. |
|
Usage and lifecycle |
Last-used or activity evidence where available, install or consent date, recent permission change, owner change, renewal or review date, exception status. |
Makes stale, changed, or unowned access visible without assuming that age alone means risk. |
|
Owner and removal path |
Business owner, technical owner, approving authority, platform administrator, revocation or uninstall method, communication route, validation step. |
Creates named accountability before access must be narrowed, revoked, or re-approved. |
Classify Permissions, Data, and Business Purpose
Classify each access relationship by both capability and business consequence. A profile-reading app, an integration that can modify business data, a service app with administrative rights, and an extension that can operate across many websites create different review questions. Classification should connect permission breadth to the resource, user population, workflow, owner, and evidence quality rather than assign a generic risk label from the application name.
-
Access type: user-delegated permission, application or service access, browser extension capability, SaaS connected app, API integration, or another documented access path.
-
Permission breadth: read, write, delete, send, administer, impersonate, or act on behalf of a user; access to specific versus broad resources; and optional or newly requested permissions.
-
Resource and data sensitivity: which SaaS service, mailbox, file, repository, calendar, CRM object, site, API, browser host, or business record can be reached within the platform's documented model.
-
Identity context: which user, group, role, service account, workload identity, or organization-wide consent is associated with the access and who can authorize it.
-
Business dependency: why the integration or extension exists, who relies on it, what would stop working if access were removed, and whether a supported alternative exists.
-
Time and review: when the access was granted or installed, when it was last used where evidence is available, when permissions changed, and what event or date requires re-review.
Establish Consent Ownership and Decision Rights
Every material SaaS access-governance program should have one accountable program owner who maintains the current access picture and separate accountable owners for consent policy, SaaS applications, browser extensions, technical administration, business purpose, exceptions, and consequential revocation decisions. Ownership does not centralize every setting; it connects permission evidence to people who can make or reverse access decisions safely.
Worksheet 2. SaaS Identity Access Decision-Rights Record
|
Field |
What to Record |
|---|---|
|
Program owner |
Inventory coverage, policy boundaries, priority review waves, unresolved evidence, exceptions, revocation backlog, metrics, decisions, and review cadence. |
|
Identity/access owner |
User and admin consent policy, permission classifications, delegated-access rules, service-app boundaries, role requirements, and evidence thresholds. |
|
SaaS/application owner |
Business workflow, application identity, affected data or resources, user population, integration dependency, permission changes, and removal consequence. |
|
Endpoint/browser owner |
Extension allow or block policy, requested permissions, host access, managed browser scope, exceptions, update review, and uninstall or disable path. |
|
Business/risk decision owner |
Approval of material exceptions, broad access, business-critical dependencies, accepted residual access, revocation trade-offs, and escalation thresholds. |
Define Access Evidence and Action Gates
Access-review depth should be proportional to both permission consequence and business dependency. Microsoft supports permission classifications that can be used with consent policy, while Chrome Enterprise can block applications or extensions that request permissions an organization does not allow. These are platform-specific mechanisms, not a universal scoring system. The practical control is to define evidence, owner, review scope, removal path, and approval threshold before broad or changed access is accepted. [3] [4]
Worksheet 3. Connected Access Decision Gate
|
Question |
Decision |
|---|---|
|
Can a user grant the requested access without administrator approval? |
Verify the organization's consent policy, requested permissions, application identity, business purpose, and owner. Where policy permits user consent, preserve evidence of the grant and define a review trigger rather than assuming it remains justified indefinitely. |
|
Does the request require administrator or organization-wide consent? |
Require an appropriately authorized reviewer, explicit permission review, business justification, affected-user scope, ownership, and a documented revocation path before granting access. |
|
Does a browser extension request permissions or host access outside the approved policy? |
Route the request for review. Confirm the extension identity, business need, exact blocked permission or host access, managed-user scope, exception duration, and uninstall or disable path before approving an exception. |
|
Does the access use a service application or non-human identity? |
Record the service identity, assigned role or scopes, credential method, owner, system purpose, resource boundary, review date, and how access will be removed when the workload changes. |
|
Did the application or extension request new permissions after prior approval? |
Treat the change as a new decision input. Compare the previous and new access, confirm the business need for the added capability, and re-approve, narrow, or deny the changed scope. |
|
Is the action limited to read-only discovery, inventory, or evidence collection? |
Permit lower-friction review work when access, privacy, least-privilege, evidence-integrity, and assigned-account boundaries remain controlled. |
Connect Apps, Extensions, Users, and Service Identities
SaaS identity risk crosses organizational boundaries because authorization is distributed across identity providers, application platforms, browser management, SaaS administrators, publishers, business owners, and users. Slack's app-approval model, for example, lets Workspace Owners pre-approve or restrict apps and makes requested scopes part of the approval decision. The model is specific to Slack, but it illustrates why the application, permissions, approver, user population, and future scope changes have to remain linked. [5]
Treat every important connection as part of an operating access model. Record what the app or extension can reach, who or what identity it uses, which platform controls the permission, who owns the business workflow, how usage is evidenced, what event should cause re-review, and exactly how access can be removed. Governance improves when those relationships are explicit instead of scattered across consent screens, browser consoles, app catalogs, and individual user settings.
Monitor, Revoke, and Validate
Approval is not completion. Connected access can remain after a project ends, a user changes roles, an app stops being used, or a business process moves to another tool. Dropbox documents user-facing third-party app access levels and a process for disconnecting linked applications. That is a Dropbox-specific example, but it reinforces the lifecycle requirement that an organization should know how to remove a connection as clearly as it knows how to create one. [6]
Validation matters because a revocation action is only useful if the intended access is actually gone and the business process remains understood. A complete review therefore distinguishes the decision to remove access from the technical action, the post-change access check, the workflow impact, and any remaining exception or alternate integration.

Score Readiness
Score each domain from 0 to 4: 0 = absent; 1 = informal; 2 = documented; 3 = implemented and tested; 4 = measured and continuously improved. Maximum score: 44. Readiness percentage = total score divided by 44, multiplied by 100. Suggested interpretation: Basic 0-24%; Developing 25-49%; Defined 50-69%; Managed 70-84%; Adaptive 85-100%. This is an internal CyberTech Intelligence readiness aid, not a certification, audit, product score, security guarantee, legal conclusion, or claim that a particular organization has unsafe access.
