The principle of Least Privilege is a security concept that ensures individuals or systems have only the minimum level of access necessary to perform their tasks. By limiting permissions, organizations reduce the risk of unauthorized access and potential damage from malicious activities or human errors. Implementing Least Privilege involves regularly reviewing and adjusting access rights for users, applications, and devices. This practice helps protect sensitive information and systems by ensuring that only authorized personnel can access critical resources, thereby enhancing overall security and compliance with regulations.
