Identity and Access Management (IAM)

Identity and Access Management (IAM) is the foundation of any robust security framework. It’s all about controlling who has access to what resources and ensuring that they only have the permissions necessary to perform their tasks. Let’s examine how AWS, Azure, and Google Cloud handle IAM.

AWS IAM: AWS Identity and Access Management (IAM) allows you to define granular permissions specifying who can access which AWS resources. You can create IAM roles, which define the actions that identities assigned to those roles can perform. IAM policies, written in JSON, are attached to users, groups, or roles to enforce fine-grained access control. AWS IAM also supports identity federation, enabling integration with on-premises identity systems using open standards like SAML 2.0, OAuth 2.0, and OpenID Connect. This allows for unified authentication across cloud and on-premises environments. AWS also offers advanced access control features like attribute-based access control (ABAC) and multi-factor authentication (MFA) for enhanced security.
Azure Active Directory (Entra ID): Microsoft Entra ID (formerly Azure Active Directory) is Azure’s cloud-based IAM solution. It uses role-based access control (RBAC) to manage access to Azure resources. RBAC allows you to define roles with specific permissions, the scope of application, and the security principles (users, groups, or application identities) assigned to each role. Azure AD seamlessly integrates with Microsoft Active Directory through Microsoft Entra Connect for identity synchronization. It also supports various identity management systems with standards like SAML, OpenID Connect, and OAuth 2.0. Azure AD provides enterprise-grade security features such as MFA, single sign-on (SSO), conditional access, and privileged identity management (PIM).
Google Cloud IAM: Google Cloud IAM provides granular control over access to Google Cloud resources. It employs a hierarchical structure, including Organization, Folder, and Project levels, to manage permissions effectively. Google Cloud IAM integrates with Google Workspace and supports external identity providers, enabling organizations to manage access across their entire ecosystem. Key features include predefined roles, custom roles, and service accounts for secure authentication of applications.
Comparison: All three cloud providers offer comprehensive IAM solutions. AWS provides exceptional flexibility and fine-grained control, particularly for complex and multi-cloud environments. Azure excels in its seamless integration with the Microsoft ecosystem, especially for organizations already using Active Directory. Google Cloud IAM offers a robust hierarchical structure for managing permissions across the GCP environment.
