What does dual control mean in security operations?

Dual control in security operations refers to the requirement for two individuals to authorize or execute critical tasks. This principle is essential in environments where the risks associated with a single individual's actions could lead to significant security breaches or operational failures. By ensuring that two people must be involved in the process, organizations can reduce the likelihood of fraud, error, or misuse of resources.

This practice is often implemented in various sensitive operations, such as financial transactions, sensitive data access, or securing physical assets, where the stakes are high. It serves as a check and balance mechanism that adds an additional layer of accountability and helps to ensure that no single person has unilateral control over critical functions.

In contrast, two-factor authentication focuses on verifying user identity by requiring two different forms of credentials, which is more about user authentication rather than operational oversight. A backup power source relates to ensuring continuity of operations rather than management processes. Maintaining physical barriers pertains to restricting access to facilities and does not involve the same level of operational oversight and control that dual control provides.
