Least Privilege
In plain terms
Granting only the minimum access needed to do a job.
Going deeper
The principle of least privilege limits each user, service, or process to exactly the permissions required, shrinking the damage from compromise. It's a core security tenet.
Under the hood
Reduces blast radius of breaches; enforced via roles, scoped tokens, and just-in-time access.
Examples
IAM policies, scoped API keys, role-based access, minimal permissions.
Think of it like...
Like giving a contractor a key to only the room they're working in, not the whole building.
