Least Privilege Access

Least privilege is a security principle that restricts permissions to the minimum needed for a job or system function. Instead of making every contractor a site administrator, an organization assigns roles according to actual tasks and removes access that is no longer required. The same idea applies to automation tokens, databases, cloud accounts, and software integrations.

NIST identifies least privilege as a principle for limiting system resources and authorizations. In website operations, implementation includes separate user accounts, role-based permissions, time-limited vendor access, regular reviews, and revocation during staff offboarding. Access may need temporary elevation for specific maintenance work, but permanent broad rights should not become the default.

Least privilege reduces the potential damage from compromised or mistaken accounts; it does not replace multifactor authentication, backups, logging, or secure development. A read-only analyst can still see sensitive information if the dataset itself is unnecessarily broad.

For a small agency, begin with the admin roster: identify who can publish content, edit code, change billing, and export customer records. Then remove unrelated permissions while ensuring the business can still recover access when an employee leaves.
