Software supply chain security is a critical challenge, and it's more than just protecting human user data and access. Non-human identities, like API keys, service accounts, and machine credentials, play a pivotal role in modern software systems. These identities often have elevated access and operate at scale. Mismanaging or neglecting them in your supply chain creates vulnerabilities that attackers can exploit.
Keeping these non-human identities secure is essential to protect software integrity, prevent data breaches, and maintain trust in your system operations.
What Are Non-Human Identities?
Non-human identities are digital identities that systems or technical processes use to perform tasks or communicate across networks. Unlike a user login, these credentials don’t belong to a specific person—they belong to machines, applications, or automated processes.
Some examples of non-human identities include:
- API keys used for backend communication.
- Service accounts that manage workloads inside cloud infrastructure.
- Workflows and CI/CD pipelines requiring access to repositories or environments.
These identities are the building blocks of automation, and they work behind the scenes to keep applications running smoothly. However, their invisible nature often means their security is an afterthought.
Why Non-Human Identities in the Supply Chain Are a Risk
The software supply chain spans everything from open-source libraries to internal pipelines. Each dependency or step introduces potential weaknesses. Non-human identities become a common target because they:
- Bypass user protections: Unlike humans, they often aren’t subject to multi-factor authentication or session monitoring.
- Enable lateral movement: If compromised, they can grant attackers access to internal systems or sensitive data.
- Operate with excessive permissions: Many non-human identities are overprivileged, granting attackers unnecessary access levels when compromised.
For instance, if a malicious actor gains access to an improperly secured service account in a CI/CD system, they could infiltrate your artifact store, inject malicious code into your applications, or compromise production workloads.
Common Mistakes in Managing Non-Human Identities
Many breaches involving non-human identities stem from preventable errors in management. Common mistakes include:
- Hardcoding credentials
Storing API keys, passwords, or service account tokens directly in source code is risky. If the repository is exposed or credentials are logged, they can easily be harvested. - Excessive permissions
Endowing non-human identities with overly broad access introduces unnecessary risk. For example, a build system’s service account may only need read access to certain repos, but instead, it’s given write access across the organization. - Lack of rotation
Static credentials that don’t rotate over time create long-term risks. If a credential is compromised, the attacker may maintain persistent access unless it’s regularly rotated. - Poor visibility
Many systems lack centralized logging and monitoring for non-human identities, making it harder to detect abnormal activity.
How to Secure Non-Human Identities in Your Supply Chain
Securing non-human identities requires stricter management and automation to eliminate weak points. Consider focusing on these steps to bolster security:
1. Centralize Credential Management
Use secrets management services to securely store and retrieve sensitive values like API keys or access tokens. Eliminate hardcoding credentials to reduce your exposure in case of a breach.
2. Implement the Principle of Least Privilege
Ensure non-human identities only have access to the resources they strictly require. Regularly audit permissions at the identity level to minimize unnecessary access.
3. Enforce Credential Rotation
Automate periodic secret rotation to lower the risk of prolonged misuse. Most cloud platforms and tools can integrate credential rotation policies with little disruption to your operations.
4. Integrate Continuous Monitoring
Enable audit logs and security monitoring tools to track the usage of non-human identities. Configure alarms for suspicious activity, such as an API key being used from an unusual location or outside expected workflows.
5. Adopt Policy as Code
Codify your security and compliance policies into automated configurations. Tools like Open Policy Agent (OPA) and policy engines in CI/CD systems can prevent misconfigured identities from entering production.
