Zero Standing Privileges (ZSP) is a cybersecurity approach where users and accounts are not given permanent access rights to sensitive systems or data. Instead, permissions are granted only when needed, for a specific task and time period, and are revoked immediately afterward. This reduces the risk of unauthorized access or misuse, even if an account is compromised, because there are no lingering privileges for attackers to exploit. ZSP is commonly used in organizations to strengthen security and support compliance by limiting the window of opportunity for potential threats.
