TL;DR: Cloud security tools often miss risky IAM usage patterns such as long-term credentials in GitHub pipelines, delegated root access, and cross-account permission-set drift, according to Exaforce. The underlying problem is not visibility alone but weak identity governance around standing credentials, trust boundaries, and continuous monitoring.

Editorial analysis by NHI Mgmt Group, based on content published by Exaforce: “Bridging the Cloud Security Gap: Real-World Use Cases for Threat Monitoring”.

Key questions

Q: What breaks when cloud teams rely on IAM alone?

A: Relying on IAM alone leaves teams blind to effective access and permission drift.

Q: Why do CI/CD secrets create more risk than many teams expect?

A: CI/CD secrets often have broad blast radius because they can authenticate to source control, cloud platforms, package registries, and deployment systems.

Q: How do teams know whether cloud IAM monitoring is actually working?

A: Cloud IAM monitoring is working when it can distinguish intended use from identity drift.

Practitioner guidance

  • Audit standing cloud credentials by workflow Inventory every long-term IAM user, access key, and static pipeline secret that can reach AWS control planes, then map each one to the workflow or task it actually supports.
  • Replace static CI/CD secrets with federated access Use short-lived credentials through OIDC for GitHub Actions and similar delivery pipelines so deployment jobs obtain access at runtime instead of storing durable keys.
  • Alert on cross-account and region drift Correlate CloudTrail, SIEM, and policy-change data to flag unusual account assumptions, region shifts, and permission-set changes that do not match the expected operating pattern.

Bottom line: Long-lived cloud credentials create a governance gap because they remain valid across tasks, locations, and execution contexts that should not share the same identity.

Standing cloud credentials create identity risk that monitoring cannot fully absorb: When the same IAM user or root path remains valid across locations, factories, and pipelines, the control problem is no longer simple alerting. The article shows that cloud teams are still treating durable credentials as if they were task-scoped, which leaves the governance layer behind the operational reality. Practitioners need to stop assuming that visibility alone is enough when identity itself persists longer than the work.

A few things that frame the scale:

  • The average time to mitigate a leaked secret is 36 hours, highlighting the operational burden of manual remediation processes, according to the 2024 State of Secrets Management Survey.
  • The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to the State of Secrets in AppSec.

A question worth separating out:

Q: Who should own trust boundaries in multi-account cloud environments?

A: Cloud trust boundaries belong to the teams that govern the management plane, not only the teams operating individual workloads. Cross-account roles, permission sets, and root access all create shared accountability, so policy change monitoring and access review need to sit with the identity and cloud governance functions together.
