IAM concepts

Identity and Access Management (IAM) concepts cover the policies, processes, and tools used to manage digital identities and regulate user access to resources. Key IAM principles include authentication, authorization, provisioning, and least privilege. Effective IAM ensures that the right users have the right access at the right time.

Categories:

Group Policy

IAM concepts
A feature used in IAM systems, especially in Active Directory environments, to manage and configure the settings of user and machine identities across an organization.

Service Provider (SP)

IAM concepts
A system, application, or service that relies on an identity provider for authentication and authorization. Service providers accept identity tokens or assertions from the IdP to grant access to their resources or functionalities.

Security Token Service (STS)

IAM concepts
STS (such as AWS Security Token Service) is a cloud service that provides temporary, limited-privilege credentials for authenticated users or workloads. These tokens allow access to resources for a specific duration, reducing the need for long-term credentials and improving security.

SPIFFE (Secure Production Identity Framework for Everyone)

IAM concepts
SPIFFE is an open-source framework for providing secure, cryptographic identities to services and workloads in dynamic, distributed systems like microservices. It defines standards for identity creation, verification, and lifecycle management across different cloud and infrastructure environments.

SPIRE (SPIFFE Runtime Environment)

IAM concepts
SPIRE is the production-grade implementation of the SPIFFE specification. It is a system that manages, issues, and verifies SPIFFE identities across distributed systems, ensuring workloads are properly authenticated within microservices environments.

Trust Provider

IAM concepts
A Trust Provider is a component that verifies the identity of workloads (applications, services) using cryptographically verifiable methods, such as certificates. Trust Providers are used to ensure that only verified and trusted workloads can access sensitive resources or other services.
