Essential 8 - Restricting administrative privileges.
Malicious actors often use malicious code (also known as malware) to exploit vulnerabilities in workstations and servers. Restricting administrative privileges makes it more difficult for malicious actors to elevate privileges, spread to other hosts, hide their existence, persist after reboot, obtain sensitive data or resist removal efforts.
An environment where administrative privileges are restricted is more stable, predictable, and easier to administer and support, as fewer users can make significant changes to their operating environment, either intentionally or unintentionally.
