Schneider has provided the following remediations:

Schneider Electric recommends the following industry cybersecurity best practices:

  • Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
  • Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
  • Place all controllers in locked cabinets and never leave them in the "Program" mode.
  • Never connect programming software to any network other than the network intended for that device.
  • Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
  • Never allow mobile devices that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
  • Minimize network exposure for all control system devices and systems and ensure that they are not accessible from the Internet.
  • 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.

4. MITIGATIONS

Schneider Electric has identified the following remediations users can apply to reduce risk:

If users choose not to apply the remediation provided above, Schneider Electric recommends immediately applying the following steps to reduce the risk of exploitation:

  1. Enable IGMP Snooping: Ensure that IGMP Snooping is enabled on the switch. This feature allows the switch to intelligently forward multicast traffic only to the necessary ports where interested hosts reside. It prevents unnecessary flooding of multicast traffic across all ports, thereby enhancing network efficiency and minimizing unnecessary load on network resources.
  2. Configure VLAN Interface Settings: Set up VLAN interface settings on the switch. It's important to have distinct configurations for each VLAN to ensure proper IGMP operation.
  3. Multicast Filtering: Use IGMP filtering to control the propagation of IGMP traffic through the network. This involves configuring filters on a switch virtual interface (SVI), per-port, or per-port per-VLAN basis. Multicast filtering helps manage IGMP snooping and controls multicast traffic forwarding effectively.

Schneider Electric strongly recommend the following industry cybersecurity best practices:

  • Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
  • Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
  • Place all controllers in locked cabinets and never leave them in the "Program" mode.
  • Never connect programming software to any network other than the network intended for that device.

4. MITIGATIONS

Siemens has identified the following specific workarounds and mitigations that users can apply to reduce the risk:

  • Spectrum Power 7: Update to V24Q3 or later version

Operators of critical power systems (e.g. TSOs or DSOs) worldwide are usually required by regulations to build resilience into the power grids by applying multi-level redundant secondary protection schemes. Siemens recommends that the operators check whether appropriate resilient protection measures are in place. The risk of cyber incidents impacting the grid's reliability can thus be minimized by virtue of the grid design. Siemens strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment. As a general security measure, Siemens strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to Siemens' operational guidelines in order to run the devices in a protected IT environment.
