AWS AWSSecurityHubReadOnlyAccess Managed Policy is an AWS managed policy that grants read-only access to Security Hub. It allows an identity to view findings, insights and configuration without changing them. This is useful for auditors and analysts, but access should still be reviewed so sensitive security findings are only exposed to identities that genuinely need visibility.
What the policy actually does in AWS Security Hub
AWS AWSSecurityHubReadOnlyAccess Managed Policy is a read-only AWS managed policy for Security Hub. It lets an identity inspect findings, insights, and configuration without granting the ability to change Security Hub settings or response outcomes.
That makes it suitable for oversight roles such as security analysts, auditors, and reviewers who need visibility into the control plane state. It is not a substitute for broader administrative access, because the policy is intentionally scoped to observation rather than action.
Why read-only access still matters for security governance
Read-only access can still expose highly sensitive security telemetry, including alert details, account relationships, control findings, and environment-wide posture information. In practice, visibility into Security Hub should be treated as access to security intelligence, not as a harmless reporting permission.
Because the policy is AWS-managed, it provides a standard access pattern, but organisations still need to decide whether the granted visibility matches the role’s actual job function. Reviewers often need broad context, while many operational users only need subsets of findings or specific accounts.
How this policy fits into least-privilege access design
This policy is best understood as a permission boundary for visibility, not for control. If a role only needs to review Security Hub output, a read-only managed policy can reduce the temptation to grant broader write privileges that are harder to justify and harder to audit.
For governance, the important question is whether the identity that receives this policy also has access to correlated data sources, ticketing systems, or console areas that would make the Security Hub view more revealing than intended. Read-only permissions can still become overexposure when combined with other permissions.
In AWS environments, that means access should be reviewed as part of the wider IAM design, not as a standalone checkbox. The policy may be narrow by itself, yet still create meaningful disclosure if attached too broadly.
When to use this policy and what to verify first
Use the policy when a role genuinely needs to inspect Security Hub findings and posture information without making changes. It is a strong fit for read-only assurance work, but it should be paired with role review, separation of duties, and periodic confirmation that the holder still needs visibility into the relevant security data.
Before attachment, confirm that the target role is the right review boundary and that the surrounding access model does not accidentally broaden what the viewer can infer. Where teams need deeper AWS IAM context around managed policies, permission boundaries, and role trust, AWS IAM Policies and Roles Guide is the most direct companion reference.
Risk and Threat Considerations
Read-only access is still a security exposure because Security Hub can reveal which assets are failing checks, where controls are weak, and how an environment is structured. If granted too widely, that visibility can help an insider, contractor, or compromised reviewer map high-value targets and security gaps without ever needing write access.
Failure mechanism: The policy itself does not change findings, but it can expose enough posture data for recon, prioritisation, or social engineering when attached to an identity that should not see those details.
Impact: Overexposed Security Hub visibility can increase the blast radius of a compromised reviewer account, leak sensitive control findings, and weaken the confidentiality of the security programme’s internal picture.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5, CIS Controls v8 and NIST Zero Trust (SP 800-207) set the technical controls, while ISO/IEC 27001:2022 defines the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | AC-6 — Least Privilege | Access to Security Hub findings should be limited to the minimum visibility needed. |
| AU-6 — Audit Record Review, Analysis, and Reporting | Security Hub is used for security monitoring, review, and analysis of findings. | |
| Recommendation — Limit Security Hub read access to roles with a documented need for the findings and posture data. Review Security Hub output through defined monitoring and reporting processes. | ||
| ISO/IEC 27001:2022 | A.5.15 — Access control | The policy is an access-control decision that governs who may view Security Hub data. |
| Recommendation — Assign Security Hub read access only under a documented access-control policy. | ||
| CIS Controls v8 | CIS-6 — Access Control Management | The term is about granting and reviewing read-only access to a security service. |
| Recommendation — Provision Security Hub read access through controlled role assignments and periodic review. | ||
| NIST Zero Trust (SP 800-207) | ZT-NIST-207 — Zero Trust Architecture | The policy exemplifies least-privilege visibility and explicit authorization for access to security data. |
| Recommendation — Apply explicit authorization checks before granting Security Hub visibility to a role. | ||
Practitioner Guidance
Governance implication: Treat this managed policy as a visibility grant that still requires role-based justification. If the user’s job only needs summaries, consider whether full Security Hub read access is broader than necessary.
What to watch for: The main operational smell is policy sprawl, where the same identity is given Security Hub read access alongside other permissions that make the findings more actionable or more revealing than intended.
Practitioner takeaway: Read-only does not mean low sensitivity, it means no control authority, so the review standard should be almost as strict as for write-capable access.
