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 hardening managed Kubernetes clusters on EKS, AKS, and GKE by implementing Pod Security Standards, network policies, workload identity, RBAC scoping, image admission controls, and runtime security monitoring. It addresses cloud-specific security features including IRSA for EKS, Workload Identity for GKE, and Managed Identities for AKS.

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 security hardening for serverless compute platforms including AWS Lambda, Azure Functions, and Google Cloud Functions. It addresses least privilege IAM roles, dependency vulnerability scanning, secrets management integration, input validation, function URL authentication, and runtime monitoring to protect against injection attacks, credential theft, and supply chain compromises.

Create custom Semgrep rules for detecting bug patterns and security vulnerabilities. This skill should be used when the user explicitly asks to "create a Semgrep rule", "write a Semgrep rule", "make a Semgrep rule", "build a Semgrep rule", or requests detection of a specific bug pattern, vulnerability, or insecure code pattern using Semgrep.

Run Semgrep static analysis for fast security scanning and pattern matching. Use when asked to scan code with Semgrep, write custom YAML rules, find vulnerabilities quickly, use taint mode, or set up Semgrep in CI/CD pipelines.
