Skill UI

A comprehensive guide detailing how to implement declarative, Git-based continuous delivery for Kubernetes. It covers setup using industry-leading tools like ArgoCD and Flux CD, adhering to OpenGitOps principles for automated, reliable, and traceable application deployments and infrastructure management.

An expert guide for designing, implementing, and optimizing large-scale, secure, and highly available cloud-native infrastructure using Kubernetes. Covers advanced topics including GitOps workflows (ArgoCD/Flux), service mesh architecture (Istio), multi-cluster management, Policy as Code (OPA), and infrastructure automation with Terraform. Ideal for platform engineers building enterprise-grade container orchestration solutions.

This expert skill performs non-intrusive static analysis to thoroughly audit AI skills and bundles. It identifies malicious patterns, data leaks, system stability risks, and obfuscated payloads across major operating systems (Windows, macOS, Linux/Unix) and mobile platforms (Android/iOS). Use it when verifying skill legitimacy or performing deep cross-platform security reviews.

This comprehensive guide details the process of creating forensically sound, bit-for-bit disk images using industry-standard tools like `dd` and `dcfldd` on Linux systems. It covers essential steps including enabling write protection, documenting source metadata, performing the acquisition, and crucially, verifying the image integrity using cryptographic hashing (MD5/SHA-256). This methodology is vital for digital forensics, incident response, and legal proceedings to ensure evidence remains unaltered and admissible.

A comprehensive guide for digital forensics analysts to investigate compromised Linux systems. This workflow details the collection and analysis of critical system artifacts, including authentication logs, shell histories, SSH keys, and system configurations. Use this methodology during incident response to detect rootkits, unauthorized persistence mechanisms, and reconstruct full attacker activity.

This comprehensive skill scans Linux systems for various persistence vectors, including crontab entries, systemd units, LD_PRELOAD injections, and shell profile modifications. It correlates these findings with auditd logs to build a detailed installation timeline, which is critical for incident response and threat hunting to detect hidden backdoors.

This comprehensive skill guides the setup and deployment of File Integrity Monitoring (FIM) using AIDE on Linux systems. It covers generating the initial baseline database, configuring monitoring rules, running scheduled checks via cron, and parsing change reports to detect unauthorized file modifications. Essential for meeting strict compliance requirements and enhancing endpoint security.

This skill covers the technical process of setting up SSL/TLS inspection (decryption) on next-generation firewalls and proxies. It details how to act as a trusted Man-in-the-Middle to intercept, decrypt, and inspect encrypted HTTPS traffic for malicious payloads, data exfiltration, and policy violations. The workflow includes generating internal Certificate Authority (CA) certificates and deploying them across various operating systems (Windows, macOS, Linux) to ensure visibility into the web's encrypted blind spot.

A comprehensive playbook detailing advanced techniques for post-exploitation security bypass on Linux systems. Covers escaping restricted shells (rbash), evading noexec/read-only filesystems using in-memory execution (DDexec, memfd_create), and circumventing mandatory access controls like AppArmor and SELinux. Essential for penetration testing and red team operations.

A comprehensive guide for diagnosing physical and logical network failures, such as CRC errors, packet drops, duplex mismatches, and flapping. It teaches users how to analyze interface counters and trends across routers, switches, and Linux hosts to pinpoint the root cause of connectivity issues.

Pi-hole is a powerful, network-wide DNS ad blocker solution that runs on Linux hosts (like Raspberry Pi). It automatically blocks ads, trackers, and malware domains for every device on your network without requiring browser extensions. This guide details installation via Docker or bare-metal setup, configuring it as the primary DNS server for a home network, managing blocklists, and implementing advanced features like DNS-over-HTTPS (DoH) for enhanced privacy.

A comprehensive guide to setting up a fast and secure WireGuard VPN server for remote access to your home network (homelab). Learn keypair generation, advanced Linux firewall (iptables) rules, and how to manage different tunneling modes (split vs. full tunnel) for optimal performance.
