This skill provides a structured methodology and tools for investigating sophisticated supply chain attacks. It focuses on detecting trojanized software updates, compromised build pipelines, and hidden dependencies by performing deep binary comparison, code signing verification, and anomaly detection. Use it during incident response to map out intrusion vectors and assess the full scope of a security breach.

This tool provides a comprehensive framework for analyzing web server logs (Apache/Nginx) to detect various security threats. It uses advanced regex matching against OWASP attack signatures to identify SQL injection, Local File Inclusion, and Directory Traversal attempts, alongside behavioral analysis for brute-force attacks and web scanner fingerprints. The system also enriches data using GeoIP for source attribution, generating a prioritized report for SOC analysts.

This skill guides the setup of Host-Based Intrusion Detection Systems (HIDS) using industry-standard tools like Wazuh, OSSEC, or AIDE. It covers essential security practices, including File Integrity Monitoring (FIM) for critical directories, monitoring system calls, detecting configuration changes, and identifying rootkits. It is crucial for meeting regulatory compliance requirements (e.g., PCI DSS) and significantly enhancing overall endpoint security posture.

This guide provides a comprehensive walkthrough for deploying, configuring, and tuning Snort 3. It covers essential steps such as setting network interfaces to promiscuous mode, writing custom rules using Lua, integrating with SIEM platforms, and utilizing community rulesets. Ideal for network security professionals implementing robust, signature-based intrusion detection at critical network boundaries.

A comprehensive guide to deploying and configuring Suricata as a high-performance Intrusion Detection System (IDS) or Intrusion Prevention System (IPS). This skill covers setting up multi-threaded packet processing for high-throughput links, enabling protocol-aware inspection (HTTP, TLS, DNS, SMB), generating structured EVE JSON logs for SIEM ingestion, and integrating advanced signature and anomaly detection capabilities.

This tool deploys advanced machine learning techniques to detect anomalies within Operational Technology (OT) and Industrial Control Systems (ICS) environments. It establishes behavioral baselines by analyzing network traffic (Modbus, DNP3, OPC UA) and communication timing. Use cases include continuous monitoring, detecting zero-day deviations, and enhancing security monitoring platforms beyond standard signature-based intrusion detection.

This tool detects critical anomalies in DNP3 communications used within SCADA and ICS environments. It employs deep packet inspection and machine learning to monitor for unauthorized control commands, protocol violations, firmware update attempts, and deviations from established network baselines. It is essential for securing critical infrastructure, such as energy grids and industrial control networks, and building robust anomaly-based Intrusion Detection Systems (IDS).

An advanced Intrusion Detection System (IDS) module designed for Operational Technology (OT) and ICS/SCADA environments. It monitors Modbus TCP/RTU traffic to detect unauthorized writes, anomalous function codes, malformed frames, and deviations from established communication baselines. Essential for investigating suspicious PLC register modifications and responding to industrial threats.

This comprehensive guide configures Fail2ban to implement a robust, layered defense mechanism for network security. It sets up custom filters and actions to automatically detect and mitigate threats such as port scanning, SSH brute force attempts, and network reconnaissance. By dynamically banning malicious IP addresses and providing security alerts, this skill significantly enhances the host-based intrusion prevention capabilities of your system.

This skill guides the deployment of canary tokens and honeytokens across critical systems, such as fake AWS credentials, DNS records, and document beacons. These decoys are designed to trigger immediate alerts via webhooks when accessed by attackers, serving as a powerful early warning system for breach detection and intrusion detection.

This guide details the deployment and configuration of Suricata as a high-performance, inline Intrusion Prevention System (IPS). It covers setting up NFQueue mode, writing custom detection rules, managing commercial and community rulesets (like Emerging Threats), and optimizing performance for active, real-time blocking of malicious network traffic. Essential for robust security architecture and compliance.

This skill demonstrates how to craft and inject custom, malformed, or spoofed network packets using tools like Scapy and hping3. It is designed for authorized cybersecurity assessments to rigorously test firewall rules, Intrusion Detection/Prevention Systems (IDS/IPS) signatures, anti-spoofing controls, and overall network stack resilience against protocol anomalies and fragmentation attacks. Use only in controlled, authorized environments.
