A Human Interface Device (HID) is a type of computer peripheral that allows humans to interact with computers or other digital systems. Common examples include keyboards, mice, touchscreens, and game controllers. HIDs communicate with computers using standardized protocols, making them easy to connect and use across different operating systems. In cybersecurity, HIDs can pose risks, as attackers may exploit vulnerabilities in these devices to gain unauthorized access or inject malicious input. Proper security measures, such as device authentication and monitoring, are essential to protect systems from HID-based threats.
