A virtual account in cybersecurity refers to a digital user identity created by services or applications to access resources securely, often without being tied to a specific physical user. These accounts are typically used to isolate privileges, manage automated processes, or enable secure interactions between software components. Virtual accounts help enforce the principle of least privilege, reducing the attack surface by granting only necessary permissions. They are commonly found in operating systems, cloud environments, and enterprise networks where automated tasks or services need controlled access to sensitive data or systems. Proper management and monitoring of virtual accounts are essential to prevent misuse or unauthorized access.
