This skill monitors critical OT historian servers (such as OSIsoft PI and Ignition) located at the IT/OT boundary. It is designed to detect sophisticated cyber threats, including unauthorized access attempts, data manipulation, suspicious query patterns, and indicators of lateral movement between enterprise and control networks. Use it to validate data integrity and respond to potential ICS security incidents.

A comprehensive methodology for detecting advanced system compromises, including rootkits, hidden processes, and kernel-level malware. It utilizes memory forensics, cross-view detection (comparing different system views), and integrity checking to identify manipulated kernel structures, hooked system calls (SSDT, IAT, IRP), and covert network connections. Ideal for deep forensic investigations where standard tools fail to reveal the true state of a compromised system.

This skill addresses advanced threat detection for critical infrastructure (OT/ICS). It monitors sophisticated, multi-stage cyber-physical attacks, focusing specifically on PLC logic integrity monitoring, detecting unauthorized modifications, and analyzing process anomalies. It covers the entire attack chain, from initial USB-borne access (IT) to process manipulation (OT).

A detailed methodology for proactive threat hunting focused on identifying deep-seated persistence mechanisms within Windows operating systems. This guide covers advanced techniques such as monitoring Run keys, analyzing Winlogon modifications, detecting IFEO injection, and identifying COM object hijacking. It is crucial for incident response, purple teaming, and ensuring system integrity against advanced persistent threats (APTs).

This skill provides a comprehensive guide on implementing AES-256-GCM, a robust symmetric block cipher, for protecting sensitive data at rest. It covers best practices including secure key derivation (using PBKDF2 and Argon2id), proper management of initialization vectors (IVs) and nonces, and utilizing authenticated encryption to ensure data integrity and detect tampering.

This skill guides implementing robust code signing for software artifacts (binaries, packages, containers). It ensures integrity and authenticity throughout the entire software supply chain. Learn to use traditional methods like GPG and modern, keyless approaches like Sigstore (cosign) to establish trust chains, verify provenance, and meet compliance standards (e.g., SLSA).

This guide details the implementation of SPF, DKIM, and DMARC—the three core pillars of email authentication. It provides a comprehensive workflow, including DNS record setup and best practices, to prevent domain spoofing, validate message integrity, and enforce strong anti-phishing policies across your organization's email system. Essential for building robust email security architecture.

This skill guides the implementation of File Integrity Monitoring (FIM) using AIDE (Advanced Intrusion Detection Environment). It covers setting up AIDE configurations, creating initial baselines, performing scheduled integrity checks, and parsing detailed change reports. This is essential for maintaining strong security controls, meeting compliance requirements, and detecting unauthorized system modifications on Linux environments.

This guide details the deployment of deception technologies, including canary files and honeypot shares, to detect ransomware activity at its earliest stages. It outlines configuring file integrity monitoring (FIM) and using specialized tokens to trigger alerts when ransomware attempts encryption or performs lateral movement, significantly enhancing security posture beyond standard EDR.

This guide details implementing robust container image provenance verification using Cosign, a Sigstore tool. It covers key-based and keyless (OIDC) signing methods, enabling secure supply chain practices. Users can sign images, attach critical attestations (such as SBOMs and vulnerability scans), and enforce verification in CI/CD pipelines and Kubernetes environments to ensure high integrity and trust.

This skill details implementing a ransomware-resistant, immutable backup strategy using the restic tool. It leverages S3-compatible Object Lock (Compliance Mode) to ensure Write Once Read Many (WORM) storage, preventing deletion or modification by attackers. The process includes automated backup, cryptographic integrity verification (restic check), and scheduled restore testing, adhering to advanced security standards like 3-2-1-1-0.

This utility implements an append-only log integrity chain using SHA-256 hash chaining. It ensures tamper detection by linking each log entry to the previous one, forming a blockchain-like structure. Functions include log ingestion, chain verification, pinpoint tamper detection, and anchoring to external timestamping services for robust audit logging and compliance.
