TL;DR: AWS IAM Identity Center helps centralize temporary access and permission sets, but the article argues that least privilege at scale still depends on governance, PAM, CIEM, and continuous review across the rest of the estate, according to Securden. The real issue is not whether AWS can issue short-lived access, but whether organisations can shrink permissions fast enough across human, privileged, and workload identities.
NHIMG editorial — based on content published by Securden: AWS least privilege and IAM Identity Center guidance
By the numbers:
- 80% faster, ays secure access policies can be deployed 80% faster, in weeks rather than months or years, when its platform is used alongside AWS IAM Identity Center.
- Securden reports a 60% lower total cost of ownership than fragmented legacy deployments when PAM, password management, endpoint privilege management, and vendor access are combined.
Questions worth separating out
Q: How should teams implement least privilege in AWS without leaving gaps outside Identity Center?
A: Use IAM Identity Center for federated AWS access, then extend the same governance model to privileged accounts, vendor access, and service credentials outside AWS.
Q: Why do temporary AWS credentials still need access reviews?
A: Temporary credentials reduce standing access, but they do not automatically remove unused permissions, stale roles, or over-broad policies.
Q: What breaks when PAM is not connected to cloud access governance?
A: Least privilege becomes uneven across the estate.
Practitioner guidance
- Define AWS permission sets by task, not by role habit Map common job functions to a small set of permission sets, then remove broad inherited permissions as actual usage becomes visible.
- Extend least privilege beyond AWS into PAM-governed access Inventory local admin accounts, database credentials, service accounts, and vendor sessions that sit outside Identity Center.
- Use access activity to shrink permissions continuously Feed CloudTrail usage and entitlement visibility into recurring access reviews, then remove unused users, roles, policies, and credentials.
What's in the full article
Securden's full article covers the operational detail this post intentionally leaves for the source:
- Step-by-step role modelling for AWS accounts, including how to map read-only, operator, developer, and break-glass access patterns.
- Concrete guidance on using CloudTrail access activity and IAM Access Analyzer to refine broad policies into narrower customer-managed ones.
- Detailed examples of how PAM, CIEM, IGA, and endpoint privilege management are combined across AWS and non-AWS systems.
- Implementation patterns for vendor access, privileged session recording, and automatic expiration of elevated rights.

Least privilege fails when organisations treat cloud-native access as the whole identity problem. AWS IAM Identity Center can centralise session-based access in AWS, but it does not govern every privileged path in the estate. If server admin accounts, vendor access, and service credentials remain outside the same control model, the least-privilege programme is only partially enforced. The implication is that practitioners must design identity governance across the full access graph, not just the cloud console.
A few things that frame the scale:
- From our research: 88.5% of organisations acknowledge that their non-human IAM practices lag behind or are merely on par with their human identity and access management efforts, according to the 2024 Non-Human Identity Security Report.
- Only 23.7% of organisations share secrets through insecure methods such as email or messaging applications, according to the 2024 Non-Human Identity Security Report.
A question worth separating out:
Q: How do you know whether least privilege is actually working in AWS?
A: Look for shrinking permission sets, fewer dormant entitlements, short-lived elevated sessions, and access review outcomes that remove rather than reapprove broad access. If identities keep accumulating exceptions or break-glass rights become routine, the programme is not reducing blast radius.
