This skill provides comprehensive guidance on hardening and securing critical process historian servers (e.g., OSIsoft PI, Honeywell PHD) operating within Operational Technology (OT) environments. It covers best practices for network placement across the Purdue Model, implementing robust access controls, establishing secure data replication architectures through DMZs (using data diodes), preventing SQL injection, and maintaining data integrity for safety-critical and regulatory reporting purposes. It is essential for minimizing cyber risks in industrial control systems.

This skill provides a comprehensive guide to hardening managed Kubernetes clusters on major cloud platforms (EKS, AKS, GKE). It details implementing critical security layers, including Pod Security Standards, least-privilege network policies, workload identity (eliminating static cloud credentials), and runtime security monitoring. Essential for securing production environments and meeting compliance requirements.

A comprehensive methodology for penetration testing web applications to identify broken access control vulnerabilities. This guide covers systematic testing for Role-Based Access Control (RBAC), privilege escalation, insecure direct object references (IDOR), and API authorization flaws in multi-tenant environments. It outlines the use of tools like Burp Suite and ffuf to map endpoints and simulate various user roles.

This guide details implementing an IEC 62443 compliant conduit architecture for secure remote access into Operational Technology (OT) environments. It mandates the use of jump servers, MFA gateways, session recording, and approval workflows within a DMZ to strictly control vendor and engineer access, eliminating direct VPN connections to critical ICS assets.

A comprehensive guide to hardening Windows Active Directory environments using Group Policy Objects (GPO). This skill configures multiple layers of defense, including AppLocker, Controlled Folder Access, and Attack Surface Reduction (ASR) rules, to prevent ransomware execution paths, block unauthorized file modifications, and restrict lateral movement across the domain.

This tool monitors Modbus TCP communication within SCADA and ICS environments to detect security anomalies. It performs deep packet inspection, baselines normal communication patterns (e.g., typical function code distribution, register access), and applies statistical analysis to identify unauthorized register writes, reconnaissance attempts, or denial-of-service attacks targeting industrial control devices.

This skill provides a comprehensive framework for validating backup reliability. It automates processes like cryptographic hash verification, running simulated restores to isolated environments, detecting silent data corruption (bit rot), and scanning for ransomware indicators. Use it before relying on backups during a major incident or ransomware attack to ensure data recoverability and compliance.

This skill analyzes Azure resource groups in depth, identifying all resources, their configurations, and complex interdependencies. It maps relationships—including network connections, data flows, and managed identities—to generate comprehensive, detailed Mermaid architecture diagrams. Use this when you need a clear, structured visualization and full documentation of an Azure environment's topology.

This guide provides comprehensive best practices for creating optimized, secure, and efficient multi-stage Dockerfiles. Learn how to separate build environments (builder stage) from minimal runtime environments, significantly reducing image size and attack surface. Topics covered include layer caching optimization, security hardening (non-root users), and using minimal base images for reproducible builds.

A comprehensive guide to optimizing CAST AI's core performance metrics, including node provisioning speed, autoscaler responsiveness, and API call efficiency. This skill covers techniques like configuring headroom, selecting optimal instance families, tuning evictors, and implementing caching for multi-cluster dashboards to ensure high availability and cost efficiency in cloud environments.

A comprehensive guide for deploying BambooHR integrations to a production environment. This checklist covers all critical stages, including pre-deployment authentication checks, API request quality assurance, data integrity validation, security compliance (PII redaction, webhook verification), robust monitoring setup, and detailed rollback procedures. It ensures a smooth and reliable go-live process.

A comprehensive reference architecture guide for deploying and managing CAST AI across multiple Kubernetes clusters (Dev, Staging, Prod). It details best practices for infrastructure provisioning using Terraform, focusing heavily on cost optimization techniques such as autoscaling, spot instance management, and environment-specific resource policies. Ideal for setting up team standards and ensuring reliable, cost-effective deployments.
