Mastering Identity Lifecycle Management for Non-Human Identities

Identity Lifecycle Management for Non-Human Identities

Managing identities of machines, applications, and services—collectively known as non-human identities—is crucial in today’s tech landscape. These identities require a structured approach to ensure security and efficiency. This blog will guide you through the key aspects of identity lifecycle management for non-human identities.

What Are Non-Human Identities?

Non-human identities refer to any identity that is not associated with a human user. This includes:

• Machine Identities: Such as servers, network devices, and IoT devices.
• Service Accounts: Used by applications for automated processes.
• Workload Identities: Associated with containers and virtual machines.

Understanding these identities is the first step in managing them effectively.

The Identity Lifecycle

The identity lifecycle for non-human identities can be broken down into several key stages:

1. Creation: This is where the identity is generated. It can involve assigning a unique identifier and setting initial permissions.
2. Provisioning: At this stage, the identity is configured with the necessary access rights to perform its required functions.
3. Usage: The identity is actively used to perform tasks, whether that’s accessing data, communicating with other services, or executing commands.
4. Maintenance: Regular checks and updates are necessary to ensure the identity remains secure and functional.
5. Deactivation: When the identity is no longer needed, it should be properly deactivated to prevent unauthorized access.
6. Deletion: Finally, the identity can be permanently deleted from the system to free up resources and enhance security.

Steps for Effective Management

To manage non-human identities effectively, follow these steps:

• Establish Clear Policies: Define who can create and manage these identities.
• Implement Automation: Use tools that can automatically handle the creation, provisioning, and deactivation of identities.
• Regular Audits: Conduct periodic reviews of identities to ensure they are still necessary and secure.
• Use Role-Based Access Control (RBAC): Assign permissions based on roles rather than individual identities to simplify management.

Real-Life Examples

Example 1: Cloud Services

In cloud environments, workload identities are essential. For instance, when you deploy a microservice, it needs a machine identity to communicate with other services securely. Proper lifecycle management ensures that these identities are created with the right permissions and disposed of when no longer needed.

Example 2: IoT Devices

IoT devices often operate autonomously. If an IoT device has a machine identity, it can request updates or send data without human intervention. Managing its lifecycle is crucial to prevent vulnerabilities, especially when deploying large numbers of devices.

Types of Non-Human Identities

• Static Identities: These do not change frequently and can be easily managed.
• Dynamic Identities: These change often, such as in cloud environments where instances are frequently spun up and down.

Comparison of Static vs. Dynamic

This structured approach to managing non-human identities ensures that both security and operational efficiency are optimized, making it essential for organizations to follow these best practices.
