Demystifying Web API Security in Azure - Jimmy Bogard - NDC Sydney 2024

Jimmy Bogard

azure api security with managed identities, azure active directory, oauth 2.0, client credentials, authorization code flow, roles, permissions, and more, explained in this informative talk.

Key takeaways
  • Managed identities simplify API security by eliminating the need for client secrets and certificates.
  • Azure Active Directory (AAD) provides a robust identity and access management system that integrates well with .NET.
  • OAuth 2.0 is a standard authorization framework that allows for secure delegation of access to resources.
  • Client credentials flow is suitable for back-end applications that don’t interact with users.
  • Authorization code flow is suitable for interactive client applications.
  • On-premises applications can use client credentials flow or authorization code flow with PKCE.
  • Roles and permissions can be defined and assigned at the Azure resource level.
  • Tokens can include claims that reflect a user’s roles and permissions.
  • Azure Identity Provider can be used to manage and issue tokens.
  • Authentication and authorization are separate concerns that should be treated independently.
  • Token acquisition and validation are critical steps in the authentication and authorization process.
  • Roles and permissions should be assigned to users and groups at the Azure resource level.
  • Azure AD groups can be used to manage access to resources.
  • Tokens can be used to acquire access to Azure resources and services.
  • Azure Identity Provider can issue tokens for both client and server-side scenarios.
