The Segregation of Duties concept states that no task, process, or duty should be assigned to a single resource/person. The responsibilities are divided among different people in an organization to prevent the danger of critical mistakes, errors, fraud, embezzlement, etc. This also leads to a requirement to regularly test user rights and roles, and try to minimize or uncover shared account usage.

Security principle that divides critical functions among different staff members in an attempt to ensure that no one individual has enough information or access privilege to perpetrate damaging fraud.
