Human Firewall

Definitions

Human Firewall is the idea that trained users and administrators can act as an active layer of defense against common attacks. Security teams use it to enforce trust, reduce exposure, improve detection, or standardize secure operations in production environments. Its value depends on correct configuration, lifecycle management, and surrounding controls, because weak defaults, poor integration, or missing visibility can create gaps that attackers exploit.
In plain English: Human Firewall is a security concept or control that helps organizations protect systems, manage trust, and notice suspicious behavior before damage spreads.
Example: "After the review, the security team rolled out Human Firewall in the affected environment, documented the operating procedure, and verified through logs and test cases that the control reduced exposure without breaking normal administrative or user workflows."
