Both GATE-E1 & GATE-E2 have reached end of life (EOL), hence no updated firmware available. ABB recommends implementing defense-in-depth principles to minimize vulnerabilities exploitation risk.
- Separate control system networks from other networks using firewall and managed switches that have minimal number of ports exposed.
- Physically protect control system from unauthorized personnel.
- Portable computers and removable storage should be scanned for viruses before connected to control system.
