What is Principle of Least Privilege?
Give every user, service, and AI agent only the access it needs - nothing more.
Principle of Least Privilege: definition
Least privilege limits blast radius. If an account, service, or agent can only touch what it genuinely needs, then a compromise, error, or manipulation can do far less damage. It applies to data access, system permissions, and - increasingly important - the actions and tools an AI agent is allowed to invoke. Over-permissioned agents are a growing risk precisely because they can act.
- Grant only the minimum access needed for the role or task
- Limits the damage from compromise, error, or manipulation
- Applies to data, systems, and AI-agent tools/actions
- Pairs with segregation of duties and just-in-time access
How Fintra handles it
Fintra applies least privilege to both people and AI agents: each agent is scoped to the specific data it may read and the specific actions and tools it may invoke, and anything beyond that scope is blocked at enforcement. Combined with adaptive trust - where broader autonomy must be earned - over-permissioning is avoided by default, and every access is logged.
Worked example
Frequently asked questions
Why is least privilege important?
Because it limits how much damage any single compromised, erring, or manipulated account or agent can do. If every actor can only touch what it truly needs, the blast radius of a breach or mistake is small - a foundational security principle.
How does least privilege apply to AI agents?
An agent should be scoped to only the data it needs to read and only the actions and tools it needs to invoke. Over-permissioned agents are dangerous because they can act, so limiting their reach is one of the most important AI-governance controls.
What is the difference between least privilege and segregation of duties?
Least privilege limits how much access any single actor has. Segregation of duties splits a process across multiple actors so no one can complete it alone. They are complementary controls - one minimizes individual reach, the other prevents concentration of a whole process.
How does Fintra enforce least privilege?
Fintra scopes each person and AI agent to the specific data and actions they need, blocking anything beyond that scope at enforcement, and pairs it with adaptive trust so broader autonomy must be earned - with every access logged.
