👉 The "weapon" permission is a critical security feature in many operating systems, particularly Linux-based ones, that restricts the execution of arbitrary code. It allows users to specify a list of trusted executable files or directories that can be run without further security checks, thereby preventing potentially malicious software from executing. When a user grants permission for a file or directory to be executed as a "weapon," the system only verifies that the file is part of the allowed list before granting execution rights. This mechanism helps protect against unauthorized code execution, enhancing system security by limiting the attack surface for malware and other threats.
