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

list-rules [OPTIONS]

~ ~ ~ ~

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.
