Siemens is preparing further updates and recommends the following mitigations until patches are available:

- Disable SNMP if this is supported by the product (refer to the product documentation). Disabling SNMP fully mitigates
the vulnerability
- Protect network access to Port 161/UDP of affected devices
- Apply cell protection concept
- Use VPN for protecting network communication between cells
- Apply defense-in-depth

Siemens recommends users configure the operational environment according to the Siemens Operational Guidelines for
Industrial Security.
