Activity-based governance is a control model that manages identity access by observing what users, services, and agents actually do. It uses real activity patterns, transaction context, and risk signals to grant, adjust, review, or revoke access, helping NHI Mgmt Group align permissions with current behavior instead of static roles alone.
How activity-based governance works
Activity-based governance shifts access decisions from static role assumptions to observed behaviour. It uses signals such as recent actions, transaction context, device or service patterns, and risk indicators to decide whether access should be granted, narrowed, stepped up, reviewed, or removed.
This model is useful when the same identity, service, or agent can behave safely in one context and become risky in another. It is less about “who someone is” in the abstract and more about what they are doing right now, how that fits expected activity, and whether that activity still matches the permission being used.
Why it matters for modern access control
Static entitlements age quickly in environments where users automate work, services call other services, and agents act on behalf of people. Activity-based governance helps reduce overpermissive access by making entitlement decisions more sensitive to current use, rather than depending only on joiner-mover-leaver workflows or periodic review cycles.
It also supports more defensible access decisions. When access is tied to observable activity, teams can explain why a permission remains necessary, why it should be reduced, or why a session or entitlement should be challenged because behaviour no longer fits the expected pattern.
For teams exploring broader control validation and coverage thinking, the same governance mindset is often paired with Breach and Attack Simulation (BAS) Guide, because both approaches depend on testing whether controls still work against realistic behaviour.
What activity signals can and cannot tell you
Activity signals are strongest when they are grounded in business context, transaction type, and normal usage patterns. A safe pattern in one system may be suspicious in another, so activity-based governance works best when the control model understands the expected task, the asset being used, and the sensitivity of the action being taken.
That same strength is also the main limitation. Behavioural signals are probabilistic, not absolute, so they can misclassify legitimate exceptions if the policy is too rigid, or miss abuse if the baseline is too broad. Good governance therefore treats activity as one input into access decisions, not the only one.
In agentic and non-human environments, the same principle applies to tool use, delegated actions, and service-to-service behaviour, where a change in activity may be the earliest sign that access is no longer appropriate.
How it differs from role-based and rule-based access
Role-based access control answers “what should this identity generally be allowed to do?” Activity-based governance asks “what is this identity actually doing, and is that still consistent with the permission?” Those are complementary questions, but they are not interchangeable.
Rule-based controls can be precise, yet they still depend on predefined conditions. Activity-based governance adds a feedback loop, so entitlement decisions can react to unusual sequences, unused permissions, sudden scope expansion, or a mismatch between current use and historical behaviour.
Used well, this turns access governance into a living control rather than a calendar-based review exercise. Used poorly, it becomes noisy monitoring without clear decision criteria.
Where it fits in identity governance
Activity-based governance is most effective when it is connected to lifecycle management, access review, and privileged access decisions. It gives reviewers more evidence than a bare entitlement list and can help distinguish permissions that are merely assigned from permissions that are actually needed.
It also creates a more practical way to spot drift. If an account, service, or agent repeatedly performs actions outside its usual scope, the governance response may need to be faster than the next scheduled certification. That makes activity one of the most useful signals for deciding whether access should remain standing, be reduced, or be reapproved.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0, NIST SP 800-53 Rev 5 and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | GV.RM-01 — Risk Management Strategy | Activity-based governance uses risk signals to adjust access decisions over time. |
| Recommendation — Define access review triggers that react to observed activity risk, not just scheduled recertification. | ||
| NIST SP 800-53 Rev 5 | AC-2 — Account Management | The term governs how access is granted, reviewed, adjusted, and revoked based on usage. |
| AC-6 — Least Privilege | Behaviour-based access reduction directly supports limiting permissions to what is currently needed. | |
| AU-6 — Audit Review, Analysis, and Reporting | Observed activity is the evidence source for governance decisions and exception review. | |
| Recommendation — Tie account status and entitlement changes to observed access behaviour and review outcomes. Reduce standing access when observed activity no longer justifies the current privilege level. Use audit and activity evidence to validate access decisions and investigate anomalous use. | ||
| NIST Zero Trust (SP 800-207) | Never trust, always verify | Context-aware access decisions align with continuous verification and adaptive trust decisions. |
| Recommendation — Continuously re-evaluate access based on current context and observed behaviour. | ||
