CISA recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability, such as:
o Exercise principles of least privilege.
o Minimize network exposure for all control system devices and/or systems,
ensuring they are not accessible from the internet .
o Locate control system networks and remote devices behind firewalls and
isolating them from business networks.
o When remote access is required, use more secure methods, such as virtual
private networks (VPNs), recognizing VPNs may have vulnerabilities and
should be updated to the most current version available. Also recognize VPN
is only as secure as the connected devices.
