![]() What is the Principle of Least Privilege (POLP) and Why is IT Important? This article provides an overview of least privilege and the importance of least privilege, privileged and non-privileged accounts, benefits and obstacles of applying the least privilege model, best practices and strategies for implementing the least privilege, and examples of the most famous exploits which could have been prevented by the least privilege. Additionally, least privilege is a fundamental component of zero-trust techniques.Īlthough the notion of least privilege is simple, its successful implementation may be challenging due to the many factors, such as heterogeneous systems, increasing the quantity and variety of applications and endpoints and diverse computing environments, etc. However, the concept of least privilege decreases cybersecurity risk and prevents data breaches regardless of a user's technical proficiency or reliability. Across third-party programs, such as Oracle, Adobe, Google, Cisco, VMware, etc., the potential of least privilege to reduce risk has been proved to be equally potent. 100% of Critical vulnerabilities in Internet Explorer and Edge would have been addressed in 2019 if admin privileges had been removed. In this age of rapidly growing and expanding technological fields, such as robotic process automation (RPA), the Internet of Things (IoT), cloud-based shadow IT applications, and other aspects of digital transformation, the least privilege is essential security control.Ĥ4% of firms surveyed for the 2021 Ponemon study experienced a third-party data breach that resulted in the exploitation of sensitive or private information over the preceding 12 months.Īccording to estimates from Forrester Research, 80% of data breaches include privileged credentials and the average cost of a data breach is $3.92 million.Īccording to the Microsoft Vulnerabilities Report 2020 released by BeyondTrust, 83% of Critical vulnerabilities on Windows systems between 20 might have been avoided by eliminating administrative privileges. Existing castle-and-moat defense strategies are outmoded and weak due to the omnipresence of threats. Best practices for cybersecurity and data protection have advanced significantly since the days when perimeter defenses were sufficient. ![]()
