What is the Principle of Least Privilege (PoLP)?
The Principle of Least Privilege (PoLP) is a security concept that ensures users and systems are granted only the minimum level of access required to perform their tasks. It is a foundational principle within Access Control and Identity and Access Management (IAM).
PoLP reduces the risk of misuse, whether intentional or accidental, by limiting exposure to sensitive systems and data. It is especially important in preventing risks such as Privilege Creep and Insider Threat.
What is the Principle of Least Privilege used for?
PoLP is used to reduce the attack surface and limit the potential impact of a security breach. By restricting access, organizations can prevent attackers from easily escalating privileges or moving laterally within a network.
It is a core component of Zero Trust architectures and is enforced through mechanisms such as Role-Based Access Control (RBAC), Multi Factor Authentication (MFA), and continuous monitoring.
