An administrator in cybersecurity is a user who has special privileges to manage, configure, and control computer systems, networks, or applications. Administrators can create or delete user accounts, assign permissions, install or update software, and enforce security policies. Their elevated access allows them to maintain system integrity, troubleshoot issues, and protect sensitive data. In business or educational environments, administrators are responsible for ensuring that only authorized users have access to critical resources and that all security protocols are followed. Because of their broad access, administrator accounts are frequent targets for cyberattacks, making it essential to secure these accounts with strong authentication and regular monitoring.
