App permission management asks what each application allows. Identity risk management asks who or what has access, how that access was granted, what it can reach across connected systems, and whether it should still exist. The identity approach is broader because it includes users, service accounts, tokens, extensions, and automations, not just named accounts.
Why App Permissions and Identity Risk Answer Different Questions
App permission management is about the capabilities an application exposes, so it is useful for understanding scope, integration breadth, and where a SaaS product can move data or trigger actions. Identity risk management asks a different and broader question: which users, service accounts, tokens, extensions, automations, and delegated connections can reach the SaaS environment, whether their access is still justified, and how much downstream exposure they create across connected systems. That distinction matters because permission review alone can look clean while risky access paths remain active.
For teams managing modern SaaS, the practical issue is not just whether an app has an approved permission set, but whether the identity behind that access is still trustworthy, properly owned, and limited to current business need. NHIMG’s Ultimate Guide to NHIs shows why this matters in practice: organisations often lack full visibility into service accounts and leave secrets valid far longer than intended. In practice, many teams discover the problem only after a connected app or automation has already accumulated more access than anyone realised.
How It Works in Practice
Permission-centric management usually starts with a SaaS admin console or app catalog. Teams review OAuth scopes, marketplace permissions, API grants, and connector settings, then decide whether the app is allowed to read mail, write files, post messages, or sync records. That is useful, but it is still app-level control. It tells you what the software can do, not whether the identity using it is the right one, whether the grant is stale, or whether the access path has expanded through delegation, refresh tokens, or embedded automations.
Identity risk management starts one layer earlier and one layer wider. It tracks who or what owns the access, how it was granted, whether the credential is human-owned or machine-owned, what systems the token can touch, and whether the access is excessive, orphaned, or no longer aligned to the current role or workload. For SaaS environments, that means looking at dormant integrations, overprivileged service accounts, long-lived tokens, and third-party automations as identity objects, not just as application features. The OWASP Non-Human Identity Top 10 is directly relevant here because it focuses on the risk created when machine identities are not inventoried, bounded, or rotated with the same discipline as user accounts.
A useful operating model is to treat app permissions as the outer envelope and identity risk as the control plane inside it. First confirm what the app is allowed to do. Then determine whether the underlying identity is still needed, whether its privileges exceed the business case, and whether its access can be revoked without breaking a production workflow. A short-lived, explicitly owned identity is far safer than a hidden integration that has accumulated broad reach over time.
Where identity risk becomes especially important is in shared SaaS ecosystems with many connected tools, since one compromised token or stale connector can become a pivot point into data, workflows, and administrative actions beyond the original app. The identity question also matters when permissions are inherited indirectly through roles, groups, or delegated authorisation rather than granted directly to the app itself. These controls tend to break down when SaaS is governed as a list of approved apps instead of a living set of access relationships.
Common Variations and Edge Cases
Tighter identity governance often increases operational overhead, because teams must maintain ownership, expiration, rotation, and offboarding for every non-human access path, not just for end users. That tradeoff is worth making when the SaaS instance supports sensitive data, production workflows, or privileged administration, but current guidance suggests a lighter touch may be acceptable for low-impact apps with narrow scopes and strong logging.
One common edge case is a well-scoped app with a badly managed identity behind it. Another is the opposite: a carefully reviewed service account whose permissions look reasonable on paper but whose token lives too long or whose ownership is unclear. SaaS admin teams should also be careful with vendor integrations that appear benign because they have few permissions at install time, then expand through reauthorisation or downstream delegation. The NHIMG lifecycle guidance for NHIs is especially helpful where the real challenge is revocation, rotation, and ownership rather than initial approval.
Practitioner takeaway: App permission reviews tell you what the SaaS platform can do; identity risk management tells you whether the access path is still justified, bounded, and safely owned. The strongest programmes use permission review as the first filter, then use identity governance to catch stale, excessive, or hidden access that permission lists alone will miss.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 and MITRE ATT&CK address the attack and risk surface, while CIS Controls v8 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 — Inventory and Ownership | SaaS identity risk depends on knowing every non-human access path and its owner. |
| NHI-03 — Secrets and Credential Management | Tokens and credentials drive SaaS access risk when they are long-lived or exposed. | |
| NHI-06 — Authorization and Least Privilege | Identity risk focuses on who can reach what across connected SaaS systems. | |
| Recommendation — Inventory all non-human SaaS identities and assign explicit owners for each one. Rotate SaaS tokens and secrets on a defined schedule and revoke unused credentials promptly. Limit each identity to the minimum SaaS permissions needed for its current function. | ||
| CIS Controls v8 | 6 — Access Control Management | This question is fundamentally about governing access paths, not just application settings. |
| 5 — Account Management | Identity risk depends on tracking accounts, service identities, and their lifecycle. | |
| Recommendation — Review and remove stale SaaS access grants before they become unnecessary exposure. Maintain an authoritative list of SaaS accounts and deprovision identities when they are no longer needed. | ||
| NIST CSF 2.0 | PR.AA-01 — Identity Management, Authentication, and Access Control | The distinction between app permissions and identity risk maps to managing identity-centric access. |
| Recommendation — Apply identity-based access governance to verify who or what is authorised before trusting a SaaS connection. | ||
| MITRE ATT&CK | T1078 — Valid Accounts | Stale SaaS identities and tokens can be abused as valid access paths by attackers. |
| Recommendation — Hunt for misuse of valid SaaS accounts, tokens, and delegated access paths. | ||
