4. MITIGATIONS

ABB has corrected this vulnerability in Drive Composer Version 2.9.1. Drive Composer Version 2.9.1 (both entry and pro) is downloadable from the product page. ABB recommends users apply the update at their earliest convenience.

For more information, please refer to the ABB Cybersecurity Advisory.

ABB recommends the following general security practices for any installation of software-related ABB products:

• Isolate special purpose networks (e.g. for automation systems) and remote devices behind firewalls and separate them from any general-purpose network (e.g. office or home networks).
• Install physical controls so no unauthorized personnel can access your devices, components, peripheral equipment, and networks.
• Never connect programming software or computers containing programing software to any network
  other than the network for the devices that it is intended for.
• Scan all data imported into your environment before use to detect potential malware infections.
• Minimize network exposure for all applications and endpoints to ensure that they are not accessible from the Internet unless they are designed for such exposure and the intended use requires such.
• Ensure all nodes are always up to date in terms of installed software, operating system, and firmware patches as well as anti-virus and firewall.
• When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.
