Excessive access rights increase the risk of cybersecurity incidents. Implementing the principle of least privilege (POLP) can help you significantly limit your attack surface and protect your organization from the financial and reputational losses that may follow a cybersecurity breach.<\/p>\n\n\n\n

This article reveals the importance of POLP and equips you with the best practices to implement it effectively. By enforcing these practices, you can minimize the risk of unauthorized access, privilege escalation, and data breaches.<\/p>\n\n\n\n

What is the principle of least privilege?<\/h2>\n\n\n\n

Imagine you have a house with many valuable possessions inside, and you’re the only one with the key. You plan to give a copy of your key to a trusted person, only to be used in case of emergency, and only for a limited time. You can apply a similar practice to your IT systems and sensitive data: the fewer “keys” you lend out, the lower the chance that someone will abuse your access privileges and steal valuable data. This approach is called the principle of least privilege.<\/p>\n\n\n\n

\u201cLeast privilege \u2014 the principle that a security architecture is designed so that each entity is granted the minimum system resources and authorizations that the entity needs to perform its function.\u201d<\/p>\nNIST Special Publication 800-53 Rev. 5<\/a><\/cite><\/blockquote>\n\n\n\n

The principle of least privilege<\/strong>, also known as least privilege access, is a cybersecurity concept wherein access rights for users and computing processes are restricted to only the data and resources needed to perform users\u2019 direct job duties and functions.<\/p>\n\n\n\n

This least privilege concept is the cornerstone of modern security practices. In fact, the principle of least privilege in cybersecurity is often implemented as part of a zero trust security model<\/a>. At the core of zero trust architecture<\/a> lies the idea that all users, devices, and other assets should not be trusted by default.<\/p>\n\n\n\n

By following the least privilege approach, you can significantly reduce the risk of credential compromise, data breaches, and other cybersecurity incidents. If attackers manage to obtain the credentials to one of your employees\u2019 accounts with minimal permissions, they will have only limited access to your resources \u2014 meaning the “blast radius” of potential damage is much smaller.<\/p>\n\n\n\n
