Cloud native security still fails where PAM and access models lag

At a glance

What this is: This is StrongDM's analysis of why cloud native security fails when access controls, PAM, and governance lag behind cloud adoption.

Why it matters: It matters because IAM, PAM, and lifecycle teams have to govern cloud resources as dynamic access environments, not as static on-prem systems with familiar control assumptions.

By the numbers:

• 72% of organisations admit they moved to the cloud before they had the right skills or resources to operate securely.
• Breaches caused by cloud vulnerabilities have increased by 540% since 2016.
• 75% of IT professionals say transitioning to the cloud significantly expanded their organization's attack surface.
• 59% believe the transition to the cloud made their organization less secure.

Context

Cloud native security is the practice of securing cloud architecture, applications, containers, and the data that runs inside them. The problem is that many organisations still try to apply access and control models built for on-premises systems to environments that change too quickly for those assumptions to hold.

StrongDM's article argues that the real gap is not cloud adoption itself but the mismatch between cloud-native operating conditions and older IAM and PAM patterns. Once infrastructure becomes dynamic, identity, access scope, and observability have to be governed as runtime conditions, not static entitlements.

The article also places shared responsibility at the centre of the problem. Cloud providers secure the underlying platform, but organisations remain responsible for configuration, access control, and monitoring across the cloud, cluster, container, and code layers.

Key questions

Q: What breaks when teams keep on-premises access models in the cloud?

A: The main failure is that access is granted as if assets were stable and centrally managed. In cloud native environments, workloads move, scale, and disappear quickly, so static roles and delayed reviews miss risk. Teams end up with broader access than they intended and less visibility than they need.

Q: When should teams prioritise PAM over additional cloud tooling?

A: Prioritise PAM when default credentials, excessive permissions, or weak privilege logging are the main exposure. In cloud-native environments, those issues often create more immediate blast radius than adding another monitoring layer. If privileged access is not controlled first, other cloud security investments have less reliable evidence to act on.

Q: What are the signs that cloud access management is failing in an organisation?

A: Common signs include orphaned accounts, inconsistent permissions across platforms, delayed de provisioning when employees change roles, and weak visibility into who accessed what and when. If audit trails are incomplete or unusual access is not flagged quickly, the control environment is failing. Those symptoms usually point to fragmented administration rather than a single point of compromise.

Q: How should teams align IAM and PAM for cloud native security?

A: IAM should define who or what is eligible for access, while PAM should govern how privileged access is issued, constrained, and logged in cloud environments. Treat them as complementary controls rather than separate programmes, because cloud-native risk emerges when identity assignment and privilege execution are managed in different silos.

Technical breakdown

Why the 4 Cs matter for access governance

The 4 Cs of cloud native security are cloud, cluster, container, and code. They describe nested control surfaces, not separate security programmes. Cloud controls govern configuration and access to the provider environment, cluster controls govern who and what can reach Kubernetes components, container controls govern image integrity and runtime trust, and code controls govern how security enters the delivery pipeline. If organisations only focus on one layer, they leave the adjacent layers exposed. In practice, access governance has to follow the asset through each layer because identity boundaries move with the workload.

Practical implication: Map access controls to each cloud layer so identity governance does not stop at the platform boundary.

Why Kubernetes changes least-privilege assumptions

Kubernetes introduces a different access problem because a single cluster contains many pods that communicate freely by design. Once an actor reaches one component, movement to others can become straightforward unless network policy, authentication, and privilege boundaries are explicit. That makes least privilege harder to define than in a traditional server model, where assets are more isolated and access paths are more static. The article's point is not that Kubernetes is insecure by default, but that security teams must actively create the boundaries that cloud-native orchestration removes by design.

Practical implication: Treat cluster access as a privilege design problem, not just a configuration task.

Why PAM becomes a cloud native control, not a legacy add-on

The article ties PAM to two recurring cloud risks: default credentials and excessive permissions. In cloud environments, default login credentials and over-provisioned admin access create broad blast radius if they are not replaced with controlled, logged, and task-appropriate access. PAM in this context is not just about privileged human sessions. It also supports access visibility, credential hygiene, and the enforcement of right-sized access across cloud resources. That matters because cloud native teams often need fast access without losing traceability over who touched what and when.

Practical implication: Use PAM to replace default credentials, constrain admin scope, and preserve access logs across cloud resources.

NHI Mgmt Group analysis

Cloud native security fails first at the access model, not the cloud layer. The article's central message is that organisations often secure the provider boundary while leaving identity and permission design rooted in on-prem assumptions. That creates a mismatch between how cloud systems behave and how access is governed. The practical conclusion is that cloud security programmes have to start from runtime access, not from perimeter inheritance.

PAM has become a cloud-native control plane for privilege control. The article treats default credentials and excess permissions as the two most visible cloud access failures. That is the right lens because cloud breaches rarely need exotic techniques when static access and broad admin scope remain in place. Practitioners should think of PAM as the mechanism that turns cloud privilege from ambient access into governed access.

Cloud native governance has to follow the workload lifecycle. Cloud, cluster, container, and code each introduce a different identity and access decision point. If joiner-mover-leaver, recertification, and access review processes are still tied to human-centric or server-centric cadences, they will miss the pace of cloud change. The field should treat lifecycle governance as a runtime discipline across infrastructure, workload, and human access alike.

Runtime observability is part of access governance, not an optional extra. The article repeatedly connects secure cloud operation with visibility into configuration, access activity, and threat monitoring. That is important because access models cannot be audited if they cannot be observed in context. Security teams need to assume that cloud-native privilege without logging is effectively unmanaged privilege, and unmanaged privilege becomes the default failure mode.

Cloud-native security now depends on the identity blast radius being smaller than the environment's change rate. That concept names the practical problem the article surfaces: cloud systems move faster than static entitlements, so security has to reduce how far one credential or permission set can reach. The implication is clear for identity leaders. If privilege scope cannot be bounded at the pace of cloud change, governance has already fallen behind.

From our research library:

• Kubernetes production adoption has surged from 66% in CNCF's 2023 survey to 82% in 2025.

What this signals

Cloud native security is really an access governance problem. The article makes clear that cloud, cluster, container, and code each need explicit identity and privilege boundaries. Security teams should assume that any cloud programme without those boundaries is relying on inherited trust rather than governed access.

Default credentials and over-provisioned permissions remain the fastest route to cloud exposure. Those two failures are still common because cloud speed makes old entitlement models feel convenient. Teams that have not reworked privileged access for cloud operations should expect their biggest risk to come from excess reach, not exotic attack chains.

Cloud-native lifecycle governance has to move with the workload. Access reviews, recertification, and offboarding are only useful when they track the actual pace of change in cloud environments. If the review cycle is slower than the infrastructure lifecycle, the control is already behind.

For practitioners

• Rebuild access controls around cloud-native runtime conditions Review whether current IAM and PAM controls assume static hosts, stable users, and predictable access paths. Cloud resources change too quickly for those assumptions, so controls need to follow dynamic infrastructure, Kubernetes components, and delivery pipelines.
• Replace default cloud credentials with governed privileged access Find cloud environments and resources that still rely on default login credentials or broad admin accounts, then move them into a controlled privileged access model with logging and task-based access scope.
• Apply least privilege to cluster communication paths Define which users, services, and pods can reach cluster components, then restrict pod-to-pod and user-to-cluster access with network policies, authentication, and explicit permission boundaries.
• Tie lifecycle reviews to cloud access reality Rework access reviews so they cover cloud entitlements, privileged access, and workload-linked permissions instead of treating cloud access as a one-time setup decision.

Key takeaways

• Cloud native security fails when organisations keep using access models that were designed for slower, more static environments.
• The article ties the biggest practical risks to default credentials, excessive permissions, and weak observability across cloud layers.
• For practitioners, the control question is not whether cloud is secure in theory but whether IAM, PAM, and lifecycle governance have been rebuilt for cloud-native operations.

Key terms

• Cloud Native Security: Cloud native security is the practice of protecting applications, platforms, and data in environments built around distributed cloud services, containers, and infrastructure automation. It treats identity, configuration, and observability as core controls because the environment changes too quickly for static perimeter models to work well.
• Privilege Access Management: Privilege Access Management is the discipline of controlling and monitoring elevated access to critical systems and data. It governs how privileged accounts, credentials, sessions, and commands are issued, used, recorded, and revoked, so administrative power is limited, traceable, and aligned to policy, risk, and operational need.
• Shared Responsibility Model: A shared responsibility model divides security duties between the cloud provider and the customer. For NHI governance, the provider supplies the platform controls, but the organisation still owns configuration, privilege review, secret handling, monitoring, and lifecycle management of its identities.
• Least Privilege: A security principle requiring that every identity, human or non-human, is granted only the minimum permissions necessary to perform its function. Least privilege is the single most effective control for reducing NHI blast radius.
