This skill covers implementing secure remote access to OT/ICS environments for operators, engineers, and vendors while preventing unauthorized access that could compromise industrial operations. It addresses jump server architecture, multi-factor authentication, session recording, privileged access management, vendor remote access controls, and compliance with IEC 62443 and NERC CIP-005 remote access requirements.

This skill covers conducting cybersecurity assessments of electric power grid infrastructure including generation facilities, transmission substations, distribution systems, and energy management system (EMS) control centers. It addresses NERC CIP compliance verification, substation automation security, IEC 61850 protocol analysis, synchrophasor (PMU) network security, and the unique threat landscape targeting power grid operations as demonstrated by Industroyer/CrashOverride and related attacks.

This skill covers analyzing Programmable Logic Controller (PLC) firmware for security vulnerabilities including hardcoded credentials, insecure update mechanisms, backdoor functions, memory corruption flaws, and undocumented debug interfaces. It addresses firmware extraction from common PLC platforms (Siemens S7, Allen-Bradley, Schneider Modicon), static analysis of firmware images, dynamic analysis in emulated environments, and comparison against known-good baselines to detect tampering.

This skill covers deploying anomaly detection systems for industrial control environments using machine learning models trained on OT network baselines, physics-based process models, and behavioral analysis of industrial protocol communications. It addresses building normal behavior profiles for SCADA polling patterns, detecting deviations in Modbus/DNP3/OPC UA traffic, identifying rogue devices, and correlating network anomalies with physical process data from historians.

This skill covers implementing a structured patch management program for OT/ICS environments where traditional IT patching approaches can cause process disruption or safety hazards. It addresses vendor compatibility testing, risk-based patch prioritization, staged deployment through test environments, maintenance window coordination, rollback procedures, and compensating controls when patches cannot be applied due to operational constraints or vendor restrictions.

This skill covers implementing network segmentation in Operational Technology environments using VLANs, industrial firewalls, data diodes, and software-defined networking. It addresses the Purdue Model-based segmentation strategy, migration from flat networks to segmented architectures without disrupting operations, configuring OT-aware firewalls with industrial protocol deep packet inspection, and validating segmentation effectiveness through traffic analysis.

This skill covers performing vulnerability assessments in OT environments using the Claroty xDome platform for comprehensive asset discovery, risk scoring, vulnerability correlation, and remediation prioritization. It addresses passive vulnerability identification through traffic analysis, active safe querying of OT devices, integration with CVE databases and ICS-CERT advisories, and risk-based prioritization that accounts for operational impact and compensating controls.

This skill covers implementing North American Electric Reliability Corporation Critical Infrastructure Protection (NERC CIP) compliance controls for Bulk Electric System (BES) cyber systems. It addresses asset categorization (CIP-002), electronic security perimeters (CIP-005), system security management (CIP-007), configuration management (CIP-010), supply chain risk management (CIP-013), and the 2025 updates including mandatory MFA for remote access and expanded low-impact asset requirements.

This skill covers hardening and securing process historian servers (OSIsoft PI, Honeywell PHD, GE Proficy, AVEVA Historian) in OT environments. It addresses network placement across Purdue levels, access control for historian interfaces, data replication through DMZ using data diodes or PI-to-PI connectors, SQL injection prevention in historian queries, and integrity protection of process data used for safety analysis, regulatory reporting, and process optimization.

This skill covers detecting cyber attacks targeting Supervisory Control and Data Acquisition (SCADA) systems including man-in-the-middle attacks on industrial protocols, unauthorized command injection into PLCs, HMI compromise, historian data manipulation, and denial-of-service against control system communications. It leverages OT-specific intrusion detection systems, industrial protocol anomaly detection, and process data analytics to identify attacks that traditional IT security tools miss.
