Proactive Defense Strategies for Distribution Systems

  • Autentivating every user and device, nt just at thee perimeter but with thee network.
  • Mikrosegmentation that restricts communication between devices to o only what it necessary.
  • Continuous monitoring of baseline behavor for anomalies (np., a PLC suddenly sending packets to an unknown IP).
