Network Security Monitor (NSM) for DeltaV Systems passively monitors packets on the DeltaV System’s Area Control Network (ACN)—a purpose-built network that transmits and receives data and control commands—to identify suspicious payloads, malformed packets, and protocol anomalies.
Once a threat has penetrated the perimeter of your system, traditional firewalls and Intrusion Prevention Systems (IPS) cannot detect hidden payloads and lateral movements within your network. Network Security Monitor (NSM) for DeltaV Systems looks deeper into network behavior to fully inspect application contents and detect malicious, covert traffic. This solution works in concert with your Security Information and Event Management (SIEM) for DeltaV Systems allowing you to correlate network traffic with events.
Continuous detection of advanced threats: With Emerson’s NSM you are able to discover anomalies within protocols, applications, and file transfers. Application-layer inspection detects anomalies by decoding application sessions to Layer 7.
Increase security awareness: NSM is tailored to provide you with the most relevant network behavior from the DeltaV Area Control Network (ACN). Our comprehensive set of rules, alerts and dashboards help you analyze network traffic on the control system layer.
Respond proactively to threats: Network monitoring provides the granular visibility needed to discover attacks before it is too late. Real-time alerting enables a proactive response from your security team.
Maintain uncompromised availability: Each of your DeltaV Smart Switches can be enabled for port mirroring. This avoids application interference and ensures there is no compromise to your DeltaV system.
