• Conduct security acceptance testing and validation of new or updated OT systems to ensure compliance with security requirements and industry best practices.
Risk Assessment & Vulnerability Management
• Perform consequence-based risk assessments for OT environments, utilizing methodologies such as Cyber Process Hazards Analysis (Cyber PHA) to identify, analyze, and prioritize cyber risks.
• Lead vulnerability management efforts for OT/ICS assets, including the use of Claroty for vulnerability identification, risk scoring, and remediation planning.
• Support clients in achieving regulatory compliance and readiness for audits related to OT/ICS cybersecurity.
Incident Response & Monitoring
• Design and implement OT/ICS security monitoring solutions, leveraging tools such as CrowdStrike for endpoint and network monitoring, and Splunk for log aggregation and analytics.
• Collaborate with IT and OT teams to develop and test incident response plans specific to industrial environments.
• Integrate monitoring and alerting workflows with ServiceNow for streamlined incident management.
Governance, Policy, and Training
• Develop and update OT/ICS cybersecurity policies, standards, procedures, and job aids.
• Deliver training and awareness programs for client personnel, including plant operators, engineers, and third-party vendors.
• Advise clients on governance frameworks and best practices for OT/ICS cybersecurity program development and maturity assessments.
