Overview

Industrial Control Systems / Supervisory Control and Data Acquisition (ICS/SCADA) devices monitor and control critical infrastructure, but what tools monitor these systems? Many ICS/SCADA systems were developed and deployed before the evolution of today’s cybersecurity threats. These systems were not designed to interface with modern IT security architecture. Typically they lack local intelligence or security awareness. Most ICS/SCADA systems are protected only by a firewall, leaving OT security operators with little understanding of who or what may be trying to penetrate and breach there systems. Passive monitoring helps fill this ICS visibility gap.

Passive monitoring deploys non-invasive network sensors that capture the communication between SCADA and PLC devices looking for possible threats. These devices listen to network traffic and have a learning capability that captures the typical communication between devices and report out when anomalous activity is detected.

Overview

On March 15 2018, the Department of Homeland Security (DHS) and Federal Bureau of Investigation (FBI) released a joint Technical Alert (TA) – TA18-074A providing information on Russian government actions targeting U.S. critical infrastructure organizations including energy, nuclear, water, aviation and critical manufacturing sectors. The TA includes the Indicators of Compromise (IOCs) and technical details on the tactics, techniques, and procedures (TTPs) used by Russian government cyber actors on compromised victim networks.
