.SH SYNOPSIS
.PP
\f[B]usbguard\-daemon\f[]\ [\f[I]OPTIONS\f[]]
.SH DESCRIPTION
.PP
The \f[B]usbguard\-daemon\f[] is the main component of the USBGuard
software framework.
It runs as a service in the background and enforces the USB device
authorization policy for all USB devices.
The policy is defined by a set of rules using a rule language described
in \f[B]usbguard\-rules.conf\f[](5).
The policy and the authorization state of USB devices can be modified
during runtime using the \f[B]usbguard\f[](1) tool.

.SH SECURITY CONSIDERATIONS
.PP
The daemon provides the USBGuard public IPC interface.
Depending on your distribution defaults, the access to this interface is
limited to a certain group or a specific user only.
Please refer to the \f[B]usbguard\-daemon.conf\f[](5) man page for more
information on how to configure the ACL correctly.
\f[B]Do not leave the ACL unconfigured as that will expose the IPC
interface to all local users and will allow them to manipulate the
authorization state of USB devices and modify the USBGuard policy\f[].
