A targeting rule is a condition used to decide which users, roles, or sessions receive access to a feature. It can be based on subscription level, identity attributes, or other policy inputs, allowing teams to deliver capabilities selectively and consistently.
Expanded Definition
A targeting rule is the policy logic that decides which users, roles, devices, or sessions receive a feature, permission, or experience. It is common in feature flag systems, entitlement engines, and policy-driven rollout workflows, where teams need selective release without changing application code.
The boundary matters: a targeting rule is not the feature itself, and it is not the identity store that supplies the attributes used for evaluation. It sits between policy intent and runtime delivery, translating conditions such as subscription tier, geography, or account status into an access decision. In practice, the strongest targeting rules are explicit, auditable, and easy to reason about, because hidden exceptions quickly become hard to govern. Guidance across vendors is still evolving, so the exact expression syntax or evaluation order may differ even when the purpose is similar.
For a broader identity and rollout context, the OWASP Non-Human Identity Top 10 is useful when targeting rules depend on machine actors, service accounts, or automation paths that need controlled access.
Examples and Use Cases
Targeting rules show up anywhere teams need consistent selective delivery. They often combine business policy with identity or session attributes so the same rule can be evaluated at scale without manual intervention.
- A SaaS product enables a premium analytics module only for tenants with an enterprise subscription and an approved billing state.
- A platform exposes a beta feature to employees in one region while excluding external customers and partner accounts.
- A security team allows an administrative workflow only when the session comes from a managed device and the user is in a privileged role.
- A release team uses a rollout rule to send a new capability to 5 percent of eligible sessions before expanding it to the full audience.
- A machine-to-machine service uses attribute-based policy to permit only specific automated jobs to call a sensitive API, reducing uncontrolled exposure.
Implementation tradeoffs are usually between precision and maintainability. More rule inputs can improve targeting accuracy, but they also increase the chance of rule drift, ambiguous precedence, and surprises when attributes change.
Security Implications
Targeting rules become security-relevant when they control access rather than simple product experience. If a rule is too broad, poorly ordered, or evaluated on stale attributes, it can expose features, data paths, or administrative functions to the wrong audience. If it is too narrow, it can block legitimate access and create operational friction that teams bypass informally.
Common failure conditions include relying on untrusted client-side conditions, using inconsistent identity attributes across systems, and failing to audit who was actually eligible when the rule evaluated. In entitlement systems, that can create access creep that is hard to detect after the fact. In rollout systems, a bad rule can turn a limited release into an unintended full exposure.
NHIMG data shows why this matters in machine and service contexts: 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface. That pattern makes selective targeting a governance control, not just a product feature, because the wrong rule can quietly expand blast radius across accounts, APIs, and automation paths. The practical warning sign is simple: if no one can explain why a subject is in or out, the rule is already too opaque to trust.
Domain and Governance Relevance
Targeting rules sit at the intersection of product control, access governance, and policy enforcement. In NHI-heavy environments, they often decide which service accounts, API clients, or automated workflows may reach a capability, which means the rule must be aligned with machine identity scope and lifecycle state. When the same rule is used for humans and non-human actors, the governance burden rises because service accounts are less visible and easier to over-entitle.
That is why targeting rules matter in non-human identity programs: they can either reinforce least privilege or become a hidden channel for broad access. If a rule is tied to subscription tier but not to identity assurance, it may unintentionally authorize automation that should have been separately constrained. If it is tied to an attribute that is never reviewed, it can preserve access long after the original business reason has expired.
For practitioners, the governance question is not whether the rule works technically, but whether it expresses a defensible policy and can be reviewed, explained, and revoked as identities or entitlements change.
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 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 Visibility | Targeting rules depend on knowing which machine identities are eligible. |
| NHI-02 — Secrets and Credential Management | Rules often gate access for service accounts and API clients using credentials. | |
| NHI-03 — Least Privilege and Access Scope | Targeting rules should restrict access to the minimum eligible audience. | |
| Recommendation — Inventory identities that can satisfy targeting rules and remove unknown accounts from policy scope. Bind rule-based access to managed credentials and revoke secrets when eligibility ends. Limit each rule to the smallest justified set of identities, roles, or sessions. | ||
| CIS Controls v8 | 5 — Account Management | Targeting rules are an account and entitlement decision point. |
| Recommendation — Review eligibility logic regularly and remove accounts that no longer qualify. | ||
| NIST CSF 2.0 | PR.AC — Access Control | Targeting rules implement access decisions based on policy attributes. |
| Recommendation — Enforce policy-based access decisions and validate rule evaluation against approved attributes. | ||
