When a cyber incident occurs in an operational technology (OT) environment, understanding what is actually happening can become difficult. Control systems may continue to display normal readings even if attackers have begun manipulating logic or feedback within Programmable Logic Controllers (PLCs) or Human-Machine Interfaces (HMIs). Operators see stable values while underlying conditions start to diverge from what is shown on screen.
If process data at the controller level is falsified, every connected monitoring and cybersecurity tool reflects the same false picture. At that point, the Chief Information Security Officer (CISO) and operations team lose reliable visibility into the physical process that underpins production and safety.
The choices that follow each carry risk:
- Shutting down operations may prevent escalation but could also cause costly downtime if the intrusion is contained to the network.
- Continuing to operate may expose critical assets to damage if the manipulation extends to the process layer.
A recent cyber event at Norway鈥檚 illustrates this limitation.
During the incident, operators lost visibility into parts of the control system, yet intrusion detection and monitoring tools reported no anomalies. The breach was discovered only when on-site personnel noticed irregular behavior in equipment operations.
This outcome speaks to a broader issue in OT cybersecurity. Network-based detection tools can confirm whether communication channels are functioning, but they cannot independently verify whether the process data itself is genuine. If attackers manipulate information within PLCs or HMIs, every connected dashboard, alarm and analytic layer reflects the same falsified values. In effect, the system becomes blind at the moment visibility is most needed.
The Risevatnet case shows how quickly a cybersecurity failure can become an operational one. When control room data appears normal, incident response slows and decisions depend on incomplete or misleading information. Without a way to validate what is happening at the physical process level, teams must rely on manual observation or external cues, a reactive approach that offers no real protection in complex or distributed environments.
SIGA鈥檚 厂颈驳补惭尝虏, available through 探花视频, addresses this visibility gap by providing an independent, out-of-band view of the industrial process. The system collects unfiltered electrical signals directly from field I/Os (data that cannot be spoofed or altered) and applies multi-level analytics across Purdue Levels 0鈥�4 to detect anomalies and false-data injections in real time.
Its components work together to create an evidence-based view of the process:
- SigaGuard sensors capture raw electrical data directly from equipment.
- SigaGuardX software correlates Level 0-4 information to identify inconsistencies and possible manipulations.
- S-PAS simulation tools allow cybersecurity and operations teams to rehearse attack scenarios and refine incident response playbooks.
These capabilities give CISOs and plant operators verifiable insight during an active incident, helping determine whether an event is operational or cyber in nature and guiding containment or recovery actions.
Regulatory frameworks including Network and Information Security Directive 2 (NIS2), Cyber Incident Reporting for Critical Infrastructure Act (CIRCIA) and the latest National Institute of Standards and Technology (NIST) guidance highlight the importance of process-level monitoring and validation.
As oversight expands, CISOs and plant operators are expected to provide verifiable evidence of what occurred during an event, more than network logs or alarms.
Meeting that requirement depends on having data sources that remain trustworthy even when control networks are compromised.
厂颈驳补惭尝虏 provides that capability, giving security and operations teams a direct, unaltered view of the physical process when clarity matters most.
