Definition
Least privilege access refers to a cybersecurity principle that limits user access rights to the minimum essential for executing tasks. It aims to minimize potential damage in case of vulnerability or security breach by limiting access to permissions and resources.
The principle applies to all company systems, processes, and users, from regular employees to administrators.
Examples of Least-Privilege Access
- Role-based access control (RBAC): Allocating access rights to users depending on their job roles or responsibilities within the enterprise, giving them just the necessary permission to execute their work.
- Separation of duties: Making sure that crucial tasks are shared among various systems or users to prevent excessive control or authority.
Least Privilege Access Implementation
- Perform a thorough user assessment of their roles and their resource access needs.
- Enforce multi-factor authentication (MFA) to protect sensitive tasks or resources.
- Regularly review and update user permissions to ensure they match job roles.
- Monitor and record user online activity to detect anomalies and security threats.
