What is Authorization?

Posted 24th Feb 2024 by Travis Swientek

Authorization determines user access levels and actions within a system, following authentication. It employs RBAC, ABAC, SSO, and MFA, ensuring secure, compliant resource access.

Authorization plays a pivotal role in cybersecurity and access management, serving as the gatekeeper that determines which resources a user can access and what actions they can perform within a system. It goes hand in hand with authentication, which verifies the user's identity, while authorization evaluates the authenticated identity against access policies to grant or deny permissions to access resources.

The Authorization Framework

The authorization process must navigate several challenges, such as managing complex and dynamic access policies to determine access rights, preventing unauthorized access, and ensuring compliance with security standards. Elements of authorization include:

  • Role-Based Access Control (RBAC) and Attribute-Based Access Control (ABAC): RBAC and ABAC models are foundational to modern authorization systems. RBAC assigns permissions based on roles within an organization, simplifying the management of user permissions across different levels of access. ABAC offers more granular control by considering various attributes (e.g., user location, time of access) when making authorization decisions.
  • Single Sign-On (SSO) and Multi-Factor Authentication (MFA): SSO enables users to access multiple applications with one set of login credentials, simplifying the user experience while maintaining security. MFA adds an additional layer of security by requiring multiple forms of verification before granting access.
  • Access Tokens and API Security: In digital environments, authorization often involves the use of access tokens, which are digital keys that grant access to specific resources for a limited time. APIs use these tokens to ensure that requests meet the defined access policies before responding with the requested data.

Approaches to Authorization

Solutions include:

  • Fine-Grained Access Control: Implementing detailed access control policies that specify exactly what actions users can perform with each resource, minimizing vulnerabilities.
  • Dynamic Authorization: Utilizing ABAC to dynamically adjust permissions based on context, providing flexible and secure access control.
  • Identity and Access Management (IAM): Deploying identity and access management (IAM) systems that support both authentication and authorization, ensuring a secure and efficient access control process.

Teleport's Take

Teleport governs authorization as a core element of its access platform, designed to meet the complex needs of modern compute infrastructure. Teleport’s approach to authorization incorporates:

  • Unified Access Control: Teleport combines RBAC, ABAC, and other access control models to offer comprehensive and flexible authorization that adapts to any organizational structure or access requirement.
  • Enhanced Security with MFA and SSO and secretless authentication: By incorporating MFA and SSO functionalities, Teleport ensures that authorization decisions are based on strong authentication methods, significantly reducing security risks. By eliminating secrets such as access tokens and using short-lived certificates, Teleport reduces the attack surface that bad actors can use to gain unauthorized access to critical systems.
  • Automated Access Requests: Teleport streamlines the authorization process with automated access requests, enabling users to obtain just-in-time access permissions based on predefined policies. This reduces administrative overhead while enhancing security.
  • Open-Source and API-Driven: As an open-source platform with extensive API support, Teleport facilitates custom integration and automation of the authorization process, catering to a wide range of use cases from traditional on-premises systems to modern SaaS and cloud environments.
  • Audit and Compliance: Teleport provides detailed logging and auditing capabilities, ensuring that all authorization decisions are recorded for compliance and security analysis.

By leveraging Teleport's advanced features, organizations can implement a robust authorization strategy that not only secures sensitive resources against unauthorized access but also ensures that users have the right level of access to perform their job functions efficiently. Teleport's focus on automation, integration, and user-centric design makes it an ideal solution for managing authorization in dynamic and distributed computing environments.
