Skill UI

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.

This skill provides comprehensive security hardening guidelines for serverless compute platforms like AWS Lambda, Azure Functions, and Google Cloud Functions. It covers essential security pillars including enforcing least privilege IAM roles, integrating robust secrets management (e.g., AWS Secrets Manager), automating dependency vulnerability scanning within CI/CD pipelines, and implementing strict input validation to mitigate risks such as injection and credential theft. Ideal for DevSecOps practitioners and security architects.

A comprehensive security script designed to test REST API authentication mechanisms for common vulnerabilities. It assesses broken token validation, missing authentication on critical endpoints, weak password policies, and session management flaws. The tool specifically evaluates JWT implementation, API key handling, and adherence to OWASP API Security Top 10, helping identify authentication bypasses before production deployment.

A comprehensive guide for systematically assessing REST and GraphQL API endpoints against the OWASP API Security Top 10 risks. This includes practical workflows for testing critical vulnerabilities such as Broken Object Level Authorization (BOLA), broken authentication, excessive data exposure, and rate limiting, using tools like Burp Suite, Postman, and ffuf. Ideal for pre-deployment audits and authorized penetration testing engagements.

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.

A comprehensive guide for assessing the security of JSON Web Token (JWT) implementations. This toolkit details attacks against cryptographic weaknesses, including algorithm confusion (e.g., RS256 to HS256), 'none' attacks, brute-forcing HMAC secrets, and claim manipulation. Ideal for penetration testing and security audits of modern APIs and SSO systems.

A comprehensive guide and framework for assessing real-time WebSocket APIs (ws:// or wss://). This skill covers critical security checks, including Cross-Site WebSocket Hijacking (CSWSH), authentication bypass, message injection attacks, input validation flaws, and denial-of-service (DoS) via message flooding. It utilizes tools like Burp Suite and Python for simulating malicious payloads and ensuring secure real-time communication channels.

This skill provides advanced techniques and code examples for monitoring, mapping, and pivoting across adversary-controlled infrastructure. It leverages Passive DNS, Certificate Transparency logs, Shodan/Censys scanning, and network fingerprinting (JARM/JA3S) to discover C2 servers, phishing domains, and exploitable assets over time, which is crucial for advanced security operations and threat intelligence gathering.

A structured guide for SOC Tier 1 analysts to triage security alerts within Splunk Enterprise Security (ES). It provides a systematic workflow for classifying severity, investigating notable events, correlating evidence across diverse data sources (proxy, firewall, logs), and making clear disposition decisions (True Positive, False Positive) required for escalation or closure.

This playbook guides Security Operations Center (SOC) analysts through a comprehensive, multi-step process for triaging and prioritizing security incidents. It covers receiving alerts from SIEM/EDR, enriching data using threat intelligence feeds (VirusTotal, AbuseIPDB), classifying the incident type (MITRE ATT&CK mapping), and calculating a severity score based on asset criticality and data sensitivity. The workflow culminates in automating ticket creation and triggering immediate response procedures via tools like PagerDuty.

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.
