This service delivers a pragmatic, risk-based security assessment for OT/ICS environments, prioritizing safety and operational availability. Using a "passive-first" methodology, we identify assets, vulnerabilities, and misconfigurations through network analysis and non-intrusive scanning, avoiding process disruption. By adopting a "hacker mindset," we review architectures, critical assets (PLCs/RTUs), and firewall policies to map attack paths. The final output is prioritized, actionable reporting—tailored for both technical teams and leadership—spanning immediate fixes to long-term resilience strategies.
Detailed Description:
- Non-Disruptive Methodology: Utilizing passive network monitoring and analysis of network traffic captures rather than active, disruptive scanning. Testing often involves "digital twin" simulations or "living off the land" techniques to validate vulnerabilities safely.
- Operational Safety Priority: Testers collaborate closely with operators to ensure all activities avoid impacting physical processes, PLC operations, or safety-critical systems.
- Network & Device Accessibility Verification: Evaluates the perimeter between IT and OT networks, verifying that segmentation effectively prevents lateral movement. It tests access controls on engineering workstations, HMIs, and PLCs to detect weaknesses in industrial protocols (e.g., Modbus, OPC).
- Pragmatic, Actionable Reporting: Reports provide a clear risk rating for each finding, focusing on exploitable vulnerabilities rather than just theoretical flaws. They offer practical, staged remediation advice tailored to legacy equipment and constraints, ensuring both short-term security boosts and long-term improvements.
- Comprehensive Assessment: Covers key security aspects aligned with standards like ISA/IEC 62443, including identification of security weaknesses in configurations, unpatched firmware, and remote access pathways.
