Key Technologies for Securing Digital Control Systems

Network Segmentation andFirewalls

One of thee mect effective strategies is to create strict network segmentation between thee IT entreprise network andthee OT (operational technology) control network.

Intruzyon Detection i Prevention Systems

Specialized ICS intrusion detection systems (IDS) and intrusion prevention systems (IPS) monitor for anomalous s behavor specific to industrial prootics like Modbus, DNP3, and PROFINET. These tools can identify command injection, unauthourised parameteter changes, or unusual traffic paraxns that often indicate ane active attack.
