Security Risk Management (SRM S-HAZOP)

Goal

  • S-HAZOP – Security Hazard and Operability Study
  • Security Risk Management solution is an application based on HAZOP threat analysis using technical control domains from IEC 62443 and NIST 800-82. The SRM module also allows to identify known vulnerabilities for OT systems devices and applications.​

SRM implementation Steps

Hazard and Operability Study (IEC 61882)​

  • Define your system and determine its boundaries. Divide the system into subsystems and specify the points of contact between the subsystems.​
  • Identify the threats for each asset belonging to the system and the consequences of the individual threats.​

Risk Matrix​

  • Develop your own risk matrix that will determine your appetite for risk.​
  • Assess the risk for each identified disaster scenario. Map each individual scenario on the risk matrix. ​

OT Security Controls (IEC 62443, ISA99, NIST 800-82)​

  • Identify technical controls that reduce the risk of cyber attacks. For each identified control, set the level of risk reduction. ​
  • Assess the risk for each disaster scenario, taking into account the implemented security technical controls.​
  • Build your security strategy on the basis of risk analysis. Implement additional security controls to reduce the level of risk to an acceptable level.​

Value for the client​

  • High Safety – cyber attacks can significantly reduce safety. Implementing appropriate technical security controls can significantly reduce the risk of an attack, and thus improve safety.​
  • High Productivity – cyber attacks can have a significant impact on reducing production. A properly conducted risk analysis allows you to optimize your production capacity.​
