The more an organisation expands into the cloud, the smaller its IAM perimeter should actually get.

As teams spin up new Cloud Run services, GKE clusters, and SaaS integrations like Teamcenter on GCP, the attack surface grows exponentially.

According to a recent article in The Hacker News, this results in what they call "Identity Dark Matter," referring to nearly 46% of identity activity that remains invisible and unmanaged.

The strategic response isn't to try and control every single service; it’s about shrinking the perimeter through consolidation:

Establish a single source of truth. All human and machine identities must flow through one authoritative system, like Okta federated with Google Cloud Identity.

Shift to policy-based access. Grant permissions based on context (who, what, where, when), rather than managing access for every individual resource.

Eliminate standing privileges. Use Just-in-Time access for resources when needed, leaving no persistent permissions to exploit.

Automate the identity lifecycle. Access is granted on hire, modified on role change, and revoked on termination, automatically.

This is especially critical as machine identities continue to multiply. Traditional methods, like managing service account key files, don’t scale well. Instead, we rely on tools such as GCP’s Workload Identity Federation, which enforces strong, short-lived credentials.

By consolidating and improving intelligent visibility, we can better secure a cloud environment that’s always evolving.
