Why 'Least Privilege' Access Policies Often Fail to Enforce Real Boundaries

Many organizations implement least-privilege access policies that approve roles through formal workflows, yet the permissions granted routinely exceed what a specific task actually requires. A technician approved to change one DNS record, for example, may receive group access allowing edits across an entire zone. Role-based access control organizes permissions but does not inherently restrict a user to only the approved action at the approved moment. Action-level authorization offers a stricter alternative by binding permissions to a specific operation, target, and set of allowed inputs rather than a broad role. Security buyers are advised to test vendors by defining exactly what an authorized user should and should not be able to do before accepting role-based access control as a sufficient answer.
