Because administrative accounts possess more privileges, and thus pose a heightened risk compared to standard user accounts, a best practice is to only use these administrator accounts when necessary, and for the shortest time needed. However, some IT roles (such as a network admin) may possess multiple accounts, logging in as a standard user for routine tasks, while logging into a superuser account to perform administrative activities. In a least-privilege environment, these are the type of accounts most users should be operating in 90 – 100% of the time.Īs a best practice, most non-IT users should only have standard user account access. Standard user accounts, sometimes called least-privileged user accounts (LUA) or non-privileged accounts, have a limited set of privileges. Superuser account privileges can include full read / write / execute privileges, and the power to render systemic changes across a network, such as creating or installing files or software, modifying files and settings, and deleting users and data. Superuser accounts, primarily used for administration by specialized IT employees, may have virtually unlimited privileges, or carte blanche, over a system. Additionally, various operating systems provide different default privilege settings for different types of user accounts. marketing, HR, or IT) as well as other parameters (seniority, time of day, special circumstance, etc.). Privileged Accounts are users with some privilege assignment, or delegation built on role-based attributes, such as business unit, (i.e. This blog provides an overview of least privilege and will cover: types of computing privileges, privileged and non-privileged accounts, privileged threat vectors and attacks, challenges to applying a least privilege model, best practices and strategies for implementing least privilege, and the cornerstone technologies for enabling a least-privilege computing environment. Many different types of identities and user roles (human, application, machine).Diverse computing environments (cloud, virtual, on-prem, hybrid).Expanding numbers and types of applications and endpoints (desktops, servers, laptops, tablets smartphones, IoT, ICS, etc.).Heterogeneous systems (Windows, macOS, Unix, Linux, etc.).While the principle of least privilege is straightforward, it can be complex to effectively implement, especially, when you consider the many variables, such as: Least privilege is also a foundational part of zero trust strategies. ![]() Enforcing least privilege is an instrumental best practice to reduce security risk and minimize business disruption resulting from errors or malicious intent. Forrester Research estimates at least 80% of security breaches involve privileged credentials. In this era of fast-emerging and evolving technology areas, like robotic process automation (RPA), IoT, shadow IT applications run from the cloud, and other facets of digital transformation, least privilege is an imperative security control to get right. In fact, adoption of “least privilege” was advanced by the publication of the “Department of Defense Trusted Computer System Evaluation Criteria” in 1985, following the recommendations of a task force dedicated to safeguarding classified data. While this blog will focus on the cybersecurity context of least privilege, no doubt you’re familiar with analogous concepts, such as “need to know” popularized amongst military and governmental circles. 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. This is an updated blog that was first published on NovemWhat is the Principle of Least Privilege (PoLP)?
