A security principle that limits access rights for accounts to the bare minimum permissions needed to perform their functions.
Description
Least-Permissive Access Control (LPAC) is a critical concept in Non-Human Identity Management (NHIM), which involves managing identities that are not human, such as machines, applications, or services. The core idea of LPAC is to grant the minimum level of access necessary for these non-human entities to function effectively, thereby reducing the risk of unauthorized access or potential exploitation. By limiting permissions, organizations can minimize their attack surface, ensuring that if a non-human identity is compromised, the potential damage is contained. This principle is particularly important in environments where automated processes are prevalent, as it helps to enforce security boundaries and safeguard sensitive data. Additionally, LPAC plays a significant role in compliance, as it aligns with regulatory requirements that mandate strict access controls. The implementation of LPAC requires continuous monitoring and assessment to adapt to changing needs and threats, making it a dynamic and ongoing process.
Examples
- A cloud application that is granted only the permissions necessary to access specific data and services, without broader access to the entire system.
- An API key that has limited access to a subset of functions within a service, restricting its capabilities to only what is needed for its intended use.
Additional Information
- LPAC helps in achieving regulatory compliance by enforcing strict access controls.
- Regular audits and reviews are essential to ensure that access permissions remain aligned with current operational needs.
