While this blog will focus on the cybersecurity context of least privilege access, no doubt you’re familiar with analogous concepts, such as “need to know” popularized amongst military and governmental circles.
Expanding numbers and types of applications and endpoints (desktops, servers, laptops, tablets smartphones, IoT, ICS, etc.).
Heterogeneous systems (Windows, macOS, Unix, Linux, etc.).The principle of least privilege is straightforward, but can be complex to effectively implement, especially when you consider the many variables, such as: However, implementing least privilege has only become more critical, and is a foundational concept of any zero trust architecture (ZTA) and identity security approach. The security landscape has rapidly shifted in recent years due to increased remote work, rapid cloud migration, and an increasingly perimeterless world, putting zero trust and identity-centric security approaches in the spotlight. Least privilege access is a timeless security principle. Enforcing least privilege access is an instrumental best practice to reduce security risk and minimize business disruption resulting from errors or malicious intent. However, least privilege access also applies to processes, applications, systems, and devices (such as IoT), as they each should have only those permissions needed to perform an authorized activity. When applied to people, the principle of least privilege (POLP), means enforcing the minimal level of user rights, or lowest clearance level, that allows the user to perform his/her role. Privilege itself refers to the authorization to bypass certain security restraints. Least privilege is the concept and practice of restricting access rights for users, accounts, and computing processes to only those resources absolutely required to perform legitimate functions. What is the Principle of Least Privilege (PoLP)?
