Puppet Class: cis_security_hardening::rules::usbguard_service

Defined in:
manifests/rules/usbguard_service.pp

Summary

Ensure the operating system has enabled the use of the USBGuard

Overview

The operating system must enable USBGuard.

Rationale: Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity.

Peripherals include, but are not limited to, such devices as flash drives, external storage, and printers.

A new feature that RHEL 8 operating systems provide is the USBGuard software framework. The USBguard-daemon 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 the “usbguard-rules.conf” file. The policy and the authorization state of USB devices can be modified during runtime using the USBGuard tool.

The System Administrator (SA) must work with the site Information System Security Officer (ISSO) to determine a list of authorized peripherals and establish rules within the USBGuard software framework to allow only authorized devices.

Examples:

class { 'cis_security_hardening::rules::usbguard_service':
  enforce => true,
}

Parameters:

  • enforce (Boolean) (defaults to: false) —

    Enforce the rule.
