What is Authorization?

What is Authorization?

Authorization in the context of Identity Governance and Administration (IGA) refers to the process of granting or denying a user or system access to specific resources, systems, or data based on predefined policies, roles, or permissions. It determines what actions a user or system is allowed to perform after their identity has been authenticated.

Key Elements of Authorization in IGA

Access Control Policies

Define rules that specify who can access what and under what conditions. For example, a policy might state that only HR employees can access sensitive payroll data.

Role-Based Access Control (RBAC)

Permissions are grouped by role, and users are assigned to roles that determine what actions they can perform and which resources they can access within an IT infrastructure. An example would be a “Manager” role might allow approval of timesheets, while an “Employee” role can only submit timesheets.

Attribute-Based Access Control (ABAC)

Provides access control at a more granular level. ABAC allows application or line managers to use attributes, or characteristics, about the access request, entitlement, or user. These attributes can be based on desired outcomes for what an identity will do with said access, what the resource or system being requested is, the location of the request, and more, etc. For example: a user might gain access to a system only during working hours or based on their location.

Principle of Least Privilege

Governs the practice of granting users, devices, and processes only the minimum access or permissions required to perform their tasks. The benefits of the principle include reducing the attack surface and mitigating the potential impact of security breaches or unauthorized access to sensitive data. An example is a developer given read-only access to a production database rather than full administrative rights.

Segregation of Duties (SoD)

Facilitates the division of tasks and responsibilities among multiple individuals to reduce the risk of error, fraud, or malicious activity. The mechanism is designed to ensure that no single individual has control over all aspects of any critical process, thereby engaging fraud prevention and limiting opportunities for mistakes or intentional wrongdoing. For example, a user who approves financial transactions cannot also create those transactions.

Entitlement Management

Controls, tracks, and governs the access rights (entitlements) that users have to systems, applications, and data within an organization. It ensures that users only have the access necessary to perform their job functions and prevents over-provisioning, unauthorized access, and security risks. An example would be an organization conducting periodic access reviews to validate if users still need access to certain resources.

Benefits of Authorization in IGA

Enhanced Security

Reduces the risk of unauthorized access and insider threats.

Compliance

Helps organizations meet regulatory requirements by enforcing access controls and maintaining audit trails.

Operational Efficiency

Streamlines access management by automating policies and approvals.

Risk Mitigation

Limits exposure by ensuring access is only granted to the right people at the right time.

Organizational Challenges to Effective Authorization Processes

Effective authorization can face several challenges that can undermine security, operational efficiency, and compliance. These include:

Role Explosion

Over time, organizations may create too many roles to accommodate specific access needs, leading to role overlap and complexity. Organizations must implement a structured role engineering process and periodically consolidate or refine roles.

Lack of Visibility

Organizations often struggle to maintain a clear view of who has access to what, especially in hybrid or multi-cloud environments. To overcome this, organizations need centralized IGA dashboards to ensure full visibility.

Inadequate Access Reviews

Incomplete, inconsistent, or rushed access reviews enable users to retain access to systems or data they no longer need, increasing the risk of insider threats or regulatory non-compliance.

Inability to Scale Processes

As organizations grow, managing access for a larger number of users, applications, and systems becomes more difficult. Automation tools in modern IGA solutions enable organizations to scale authorization processes effectively.

Where to Learn More and Get Help

Effective authorization is essential to control and monitor access to an organization’s sensitive data and is a critical factor in mitigating the risk of data breaches. For security teams, compliance officers, and IT executives, choosing the right system enables their organizations to meet new and ongoing authorization challenges.
