Regularly review the permissions of all accounts and groups, especially those with privileged access to vital resources such as Active Directory (AD). Enumerate all accounts and the membership of all groups, including all built-in administrative groups. Scan and catalog all systems and directories attached to the corporate network. How to Implement the Principle of Least Privilegeįor stronger information security, follow these steps to implement the principle of least privilege (POLP). Instead, admins must request the elevated rights they need to complete a specific task. But with zero standing privilege, those accounts lack the necessary elevated rights to do that kind of serious damage. The owners of those accounts - or an attacker who comprises them - could deliberately or accidentally modify critical software settings or delete valuable data. Indeed, many organizations today have dozens or even hundreds of accounts with elevated rights to sensitive data and applications. Implementing ZSP can dramatically reduce the attack surface area of your business. Once you can efficiently grant users elevated access exactly when it’s needed, you can eliminate their “always-on” privileged accounts. Zero standing privilege (ZSP) is a privileged access management (PAM) strategy that goes hand-in-hand with JIT. Of course, in keeping with a Zero Trust security model, the process should include verifying the identity of the person requesting access. In particular, organizations can grant just-in-time access to IT team members who need to perform an administrative task, such as resolving a support ticket. JIT is normally used for employees who temporarily need high-level access or access to applications, systems, servers or other IT resources they do not normally use. Once the user completes the task, the system automatically destroys those credentials. Just-in-time (JIT) access involves creating new credentials every time a user requests access to a resource. Use a just-in-time (JIT) strategy to grant elevated access rights An if an adversary takes over the user’s account, they will have access to only a limited set of IT resources. After all, if a user does not have access to sensitive data, they cannot accidentally attach those files to an email or deliberately download them to take to a competitor when they quit. One of the most effective - and yet underutilized - ways to reduce risk is to ensure each user has only the type and level of permissions needed to get their job done. Three key strategies are especially valuable for implementing the principle of least privilege: Limit the rights of user accounts
