NAME

6       usbguard-daemon - USBGuard daemon
7

SYNOPSIS

9       usbguard-daemon [OPTIONS]
10

DESCRIPTION

12       The usbguard-daemon is the main component of the USBGuard software
13       framework. It runs as a service in the background and enforces the USB
14       device authorization policy for all USB devices. The policy is defined
15       by a set of rules using a rule language described in
16       usbguard-rules.conf(5). The policy and the authorization state of USB
17       devices can be modified during runtime using the usbguard(1) tool.

SECURITY CONSIDERATIONS

59       The daemon provides the USBGuard public IPC interface. Depending on
60       your distribution defaults, the access to this interface is limited to
61       a certain group or a specific user only. Please refer to the
62       usbguard-daemon.conf(5) man page for more information on how to
63       configure the ACL correctly. Do not leave the ACL unconfigured as that
64       will expose the IPC interface to all local users. That will allow them
65       to manipulate the authorization state of USB devices and modify the
66       USBGuard policy.
