Securing Non-Human Identities Across the Enterprise

Non-Human Identities (NHIs)—service accounts, bots, API keys, and cloud resources—now outnumber humans by at least 17 to 1.

They are the silent workforce of the digital age. They are also the silent killer of security postures.

Why NHIs are Dangerous

**They Don't Complain:** If an attacker steals an API key, the key doesn't call the helpdesk to say "I can't log in."

**They Don't Sleep:** They work 24/7, masking attacker activity that happens at 3 AM.

**They Have High Privileges:** We tend to over-provision them "just to make it work."

The NHI Lifecycle

**Creation:** Who is allowed to create a new service account? This should be a governed process, not a free-for-all.

**Rotation:** Static keys are dead keys. Implement automated rotation (e.g., every 30 days) for all machine credentials.

**Decommissioning:** When the application is retired, the identity must die with it.

Strategy: The "Identity Wrapper"

You can't give a robot an MFA token. But you can wrap it in controls.

**IP Allow-listing:** "This API key can only be used from this specific IP address."

**Velocity Limits:** "This service account can only read 100 records per minute."

**Time-Bound Access:** "This deployment key is only valid during the deployment window (Friday 8-9 PM)."

The Cloud Problem (AWS/Azure/GCP)

In the cloud, *everything* has an identity. A Lambda function has a role. An EC2 instance has a profile.

**Least Privilege for Compute:** Ensure your compute resources only have the permissions they need. A web server doesn't need permissions to delete S3 buckets.

How Cydenti Helps

Cydenti specializes in the "17:1" problem.

**Discovery:** We find all the NHIs you didn't know you had (shadow bots, legacy keys).

**Usage Analysis:** We analyze the actual API calls made by these identities to recommend right-sized policies.

**Secret Scanning:** We integrate with your repos and pipelines to catch leaked credentials before they become a breach.

Conclusion

Securing humans is about psychology (training, phishing tests). Securing non-humans is about engineering (rotation, automation, constraints). You need a dedicated strategy for your digital workforce.
