The critical security boundary in modern cloud infrastructure where identity controls meet resource access.
What This Category Represents
Cloud IAM misconfigurations are the root cause behind most large-scale cloud breaches. They occur when cloud identity controls roles, policies, trust relationships, workload identities, and permissions models are misaligned or overly permissive.
Cloud IAM misconfigurations are especially dangerous because they combine identity, cloud resource access, and machine automation into powerful attack surfaces that adversaries actively exploit.
Attacker Capabilities
Escalate privileges using cloud APIs
Abuse machine identities
Pivot across workloads and subscriptions
Access sensitive storage and compute resources
Hijack automation pipelines
Create long-term persistence
Critical Cloud IAM Failures
Overprivileged Cloud Roles
Owner, Contributor, and Admin roles assigned broadly to humans or machines with no segmentation across subscriptions. Excessive permissions in multi-cloud environments create unlimited attack surfaces.
Impact: A single compromised identity becomes a full cloud takeover.
Misconfigured Managed Identities
Workload identities granted admin-level cloud roles, reused across unrelated workloads, with no isolation based on application boundaries or security zones.
Impact: Enables machine-to-cloud privilege escalation at scale.
VM/Container Identity Exposure
Identity tokens stored in filesystem, metadata endpoints accessible without restriction, and missing identity-bound constraints on compute resources.
Impact: Attackers hijack workloads and expand privileges instantly.
Policy and Permission Failures
Overly Broad IAM Policies
Wildcard permissions, unknown or poorly documented custom roles, and excessive API surface exposure create hidden privilege escalation paths.
Hidden privilege escalation paths through cloud APIs
Cloud Resource Misalignment
Identities with write access to key vaults, ungoverned storage SAS tokens, and secrets exposed to workloads unnecessarily.
Azure ↔ AWS ↔ GCP federation and role assumptions without constraints, no identity boundaries, and no workload isolation.
Attackers pivot across clouds using one foothold
Operational Security Gaps
No Conditional Access for Cloud Administrative Actions
Cloud admin actions allowed without risk evaluation or context-aware controls. No protections against automation abuse or anomalous API operations.
Critical Impact: Attackers perform high-impact API operations silently, bypassing all traditional detection mechanisms.
Lack of IAM Drift Detection
Roles change without alerts, privileges accumulate over time, and old service principals never reviewed or deprovisioned.
Critical Impact: Privilege creep creates immediate escalation opportunities that remain undetected for months.

Breach Prevention Rate
Strong Cloud IAM posture prevents full tenant compromise in over half of identity-centric breaches

Continuous Review Required
Cloud drift creates hidden escalation paths over time annual reviews are insufficient
Mapping to Identity Attack Chain (IAC)
Cloud IAM misconfigurations enable multiple stages of sophisticated identity-based attacks, providing adversaries with escalation paths and persistence mechanisms.
