DESCRIPTION
The usbguard command provides a command-line interface (CLI) to the usbguard-daemon(8) instance and provides a tool for generating initial USBGuard policies.
SUBCOMMANDS
list-devices
List all USB devices recognized by the USBGuard daemon.
Available options:
-a, --allowed
List allowed devices.
-b, --blocked
List blocked devices.
-h, --help
Show help.
~ ~ ~
allow-device [OPTIONS] <id>
Authorize a device identified by the device id to interact with the
system.
Available options:
-p, --permanent
Make the decision permanent. A device specific allow rule will
be appended to the current policy.
-h, --help
Show help.
~ ~ ~
block-device [OPTIONS] <id>
Deauthorize a device identified by the device id.
Available options:
-p, --permanent
Make the decision permanent. A device specific block rule will
be appended to the current policy.
-h, --help
Show help.
~ ~ ~
reject-device [OPTIONS] <id>
Deauthorize and remove a device identified by the device id.
Available options:
-p, --permanent
Make the decision permanent. A device specific reject rule will
be appended to the current policy.
-h, --help
Show help.
~ ~ ~
list-rules [OPTIONS]
List the rule set (policy) used by the USBGuard daemon.
Available options:
-h, --help
Show help.
~ ~ ~
append-rule [OPTIONS] <rule>
Append the rule to the current rule set.
Available options:
-a, --after <id>
Append the new rule after a rule with the specified rule id.
-h, --help
Show help.
~ ~ ~
remove-rule [OPTIONS] <id>
Remove a rule identified by the rule id from the rule set.
Available options:
-h, --help
Show help.
~ ~ ~
generate-policy [OPTIONS]
Generate a rule set (policy) which authorizes the currently connected
USB devices.
Available options:
-p, --with-ports
Generate port specific rules for all devices. By default, port
specific rules are generated only for devices which do not
export an iSerial value.
-P, --no-ports-sn
Don't generate port specific rules for devices without an
iSerial value. Without this option, the tool will add a
via-port attribute to any device that doesn't provide a serial
number. This is a security measure to limit devices that cannot
be uniquely identified to connect only via a specific port.
This makes it harder to bypass the policy since the real device
will occupy the allowed USB port most of the time.
-t, --target <target>
Generate an explicit "catch all" rule with the specified target.
The target can be one of the following values: allow, block,
reject
-X, --no-hashes
Don't generate a hash attribute for each device.
-H, --hash-only
Generate a hash-only policy.
-h, --help
Show help.
~ ~ ~
watch [OPTIONS]
Watch the IPC interface events and print them to stdout.
Available options:
-h, --help
Show help.
~ ~ ~
read-descriptor [OPTIONS] <file>
Read a USB descriptor from a file and print it in human-readable form.
Available options:
-h, --help
Show help.
EXAMPLES
Creating an initial policy
$ sudo usbguard generate-policy > rules.conf
$ vi rules.conf
(review/modify the rule set)
$ sudo install -m 0600 -o root -g root \
rules.conf /etc/usbguard/rules.conf
