Non-Human Identities Risk Exposure Management: Securing the Digital Frontier

Cybersecurity, NHI, Risk Management

Cybersecurity, Security Assessments

In the evolving landscape of cybersecurity, the concept of identity has extended far beyond human users. Non-human identities (NHIs) — including service accounts, APIs, bots, and IoT devices — now dominate the modern digital environment. They are indispensable for seamless communication, automation, and efficient workflows in today’s interconnected systems. However, as these entities proliferate, so too do the associated risks. Mismanagement of NHIs poses severe security challenges, potentially leading to breaches, data theft, and operational disruptions.

Managing the risk exposure of non-human identities is no longer optional but a critical mandate for organizations aiming to protect their digital assets and ensure business continuity. This article explores what non-human identities are, the risks they pose, and how organizations can manage them effectively.

Understanding Non-Human Identities

Non-human identities refer to the digital representations of applications, machines, bots, and services that interact within IT ecosystems without direct human involvement. These entities utilize credentials, such as API keys, OAuth tokens, SSH keys, and certificates, to authenticate and execute tasks autonomously.

Examples of non-human identities include:

Application programming interfaces (APIs): Used for secure communication between applications.
Service accounts: Employed by automated processes or services to access databases and perform system-level tasks.
Bots and scripts: Facilitate repetitive tasks or engage in user-like interactions.
IoT devices: Authenticate and communicate within connected environments.

The sheer number of NHIs in modern systems surpasses human identities by a factor of 10 to 50, especially in cloud-native environments and microservices architectures.

The Proliferation of NHIs: Why They Matter

Non-human identities are growing at an unprecedented rate, far outpacing human identities in most organizations. This growth is fuelled by the increased adoption of cloud technologies, automation, and decentralized IT environments. Here’s why their proliferation matters:

Cloud Adoption
Cloud service providers rely heavily on APIs and service accounts for operational efficiency. For instance, managing workloads in AWS, Azure, or Google Cloud involves dozens of non-human identities to handle resource provisioning, scaling, and monitoring. Each NHI represents a potential attack vector if not managed securely.
Automation and DevOps
In DevOps environments, NHIs are the linchpins of CI/CD pipelines. Tools like Jenkins, Kubernetes, and Docker create service accounts and use API keys to automate builds, deployments, and monitoring. This means every component in these automated workflows requires unique non-human credentials, contributing to the exponential growth of NHIs.

3. Third-Party Integrations
Organizations increasingly depend on third-party SaaS solutions and integrations. APIs serve as bridges between these platforms, enabling seamless data exchange. Each API comes with its own authentication tokens or certificates, further inflating the number of NHIs.

4. Microservices Architecture
Microservices have replaced monolithic applications in many organizations due to their scalability and modularity. However, each microservice often requires non-human identities to communicate securely with other services. A single application can thus spawn hundreds of NHIs.

5. Internet of Things (IoT)
IoT devices often operate autonomously, authenticating with cloud services and transmitting data without human intervention. As IoT adoption rises in industries like healthcare, manufacturing, and logistics, the number of non-human identities grows alongside.

Risks Associated with Non-Human Identities

Credential Exposure

NHIs rely on credentials for authentication, but these credentials are often stored insecurely. Common mistakes include:

Hardcoded Secrets: Developers sometimes hardcode API keys or tokens directly into source code, inadvertently exposing them in public repositories.
Misconfigured Repositories: Credentials stored in unprotected storage locations can be accessed by attackers scanning for open repositories.
Long-Lived Credentials: Unlike human credentials, NHI credentials are often not rotated regularly, leaving them vulnerable to prolonged exploitation.

If attackers gain access to an NHI credential, they can impersonate the entity, accessing sensitive systems or data.

Orphaned Identities

Orphaned NHIs result from incomplete decommissioning processes. For example, when a service or application is retired, its associated NHIs may remain active, often with their permissions intact.

These unmanaged NHIs create blind spots that attackers can exploit, gaining access to systems without detection.

Privilege Escalation

NHIs are often granted more permissions than necessary to simplify workflows. For example, a service account intended to read data may also have write privileges. If compromised, attackers can exploit these privileges to escalate access.

Overprivileged NHIs increase the blast radius of attacks, potentially affecting critical systems.

Supply Chain Attacks

Many NHIs are tied to third-party services. Attackers targeting an API or third-party integration can gain entry into multiple organizations, leveraging the interconnectedness of supply chains.

Compromised NHIs in third-party services can result in widespread breaches, similar to the SolarWinds attack.

Compliance Risks

NHIs accessing sensitive data must comply with regulations like GDPR or HIPAA. Mismanaged NHIs can result in unauthorized access, leading to violations and penalties.

Non-compliance due to mismanaged NHIs damages reputation and incurs financial penalties.

Challenges in Managing Non-Human Identities

Managing NHIs poses distinct challenges due to their unique characteristics:

Decentralization

NHIs are not governed centrally, unlike human identities managed through directories like Active Directory or LDAP. Instead, they are scattered across tools, platforms, and teams. This fragmentation makes it difficult to gain visibility into all active NHIs.

Example: In a hybrid cloud environment, NHIs might exist across AWS, Azure, and on-premises servers, each with its own management interface.

Dynamic Nature

NHIs have short lifecycles compared to human identities. For instance:

Temporary tokens may be generated and expire within hours.
Service accounts may be spun up for a specific task and deprecated shortly after completion.

This constant flux makes tracking and managing NHIs a moving target.

Ambiguity in Ownership

Unlike human identities linked to specific individuals, NHIs often lack clear ownership. A service account used by multiple applications or teams may not have a designated owner responsible for its security.

Without clear accountability, NHIs can become unmanaged, increasing risk.

Inadequate Tools

Traditional IAM tools are designed for human users, relying on predefined attributes like name, department, and role. NHIs lack such attributes, requiring specialized tools for discovery, classification, and management.

Scaling Challenges

Large organizations may have millions of NHIs. Scaling traditional identity management approaches to handle this volume is neither practical nor effective.

Risks Associated with Non-Human Identities

Credential Exposure

NHIs rely on credentials for authentication, but these credentials are often stored insecurely. Common mistakes include:

Hardcoded Secrets: Developers sometimes hardcode API keys or tokens directly into source code, inadvertently exposing them in public repositories.

Principles of Effective Non-Human Identity Management

Addressing the risks associated with NHIs requires a holistic approach that combines technology, processes, and governance. Below are the key principles:

Comprehensive Discovery

Organizations must first understand the scope of their NHI landscape. This involves:

Automated Scanning: Tools that scan environments for active service accounts, API keys, and other NHIs.
Real-Time Discovery: Continuously updating the inventory as new NHIs are created or deprecated.

A complete inventory of NHIs, serving as the foundation for risk management.

Classification and Risk Assessment

Once discovered, NHIs should be classified based on their:

Functionality: What tasks they perform.
Access Levels: What systems or data they can access.
Risk Profile: How critical they are to operations and how much damage could occur if compromised.

Example: High-risk NHIs accessing sensitive financial data should have stricter controls than low-risk ones used for monitoring.

Secure Credential Management

Vaulting Solutions: Store NHI credentials in secure, encrypted vaults accessible only to authorized entities.
Credential Rotation: Implement policies to rotate credentials frequently, reducing the risk of long-term exposure.
Secret Scanning: Use tools to scan for hardcoded credentials in codebases and rectify vulnerabilities.

Governance and Ownership

Assigning clear ownership of NHIs is critical for accountability. Organizations should:

Identify teams or individuals responsible for each NHI.
Define policies for managing the NHI lifecycle.

Monitor compliance with these policies regularly.

Example: A DevOps team might own service accounts used in CI/CD pipelines, ensuring they follow best practices for access control and rotation.

Access Control and Least Privilege

NHIs should only have the permissions necessary to perform their functions. Implement the principle of least privilege:

Regularly audit permissions to detect and revoke excessive privileges.
Use role-based access control (RBAC) to simplify permission management.

Reducing privilege levels minimizes the potential damage of a compromised NHI.

Monitoring and Anomaly Detection

Continuous monitoring is essential for detecting suspicious behavior. This includes:

Anomalous activity, such as an API key accessing unfamiliar systems.
Misconfigured or unused NHIs.

Modern tools leverage AI and machine learning to identify patterns, flagging deviations from normal behavior.

Lifecycle Management

Automating the lifecycle of NHIs ensures they are created, used, and retired securely:

Provisioning: Enforce security policies during NHI creation.
Decommissioning: Automate the removal of NHIs no longer in use.

Automation reduces the risk of orphaned identities and ensures consistent management practices.
