a technique where a credential or a permission is granted to a principal for a temporary timeframe when they need the permission to perform an activity. PAM often involves check-out and check-in of a credential generated for a single use. Certification is the ongoing review of who has which accesses (i.e., the business process to verify that access rights are correct).Ī mechanism for managing temporary access for accounts with high-risk permissions. Account takeover is a form of identity theft and fraud, where a malicious third party successfully gains access to a user’s account credentials. “The principle that a security architecture should be designed so that each entity is granted the minimum system resources and authorizations that the entity needs to perform its function.” We will contrast least privilege applied to RBAC and Policy-Based Access Control (PBAC), but roles will be the primary mechanism for grouping permissions in this article. Roles provide a natural way to encapsulate multiple permissions to reduce maintenance versus assigning multiple permissions to a human or non-human principal. This utilization is a natural extension of Role-Based Access Control (RBAC), though not all organizations use roles to model permissions in the same way. We will utilize roles as a way of grouping together permissions related to identity and activities. We will examine the advantages of long and short-term permission assignments, considering techniques like just-in-time (JIT) permissions. This article will discuss least privilege in the context of identity lifecycle and building policy for specific activities. Understanding techniques to create and refine permissions can help you approach least privilege and reduce the risk of an overly-permissive posture. Is a hypothetical, best-case scenario of a human or non-human actor having only the permissions required to perform a task at the time it needs to be performed. It is a challenging balance to give employees, partners, and customers a sufficient level of privilege to digital resources without leaving an organization open to risk. SaaS and IaaS providers are constantly changing the surface area of permissions that customers need to manage. People take on temporary assignments, and organizations are typically better at granting permissions than taking them away. Workforce members accumulate permissions throughout their employment, and job requirements change regularly. Reducing excessive permissions is a continuous effort.
