Skill UI

Expert in implementing Infrastructure as Code (IaC) using Terraform across multi-cloud environments, including AWS, Azure, and GCP. Specializes in creating reusable, modular components, advanced state management (backends, locking, migrations), ensuring security best practices, and developing robust, production-grade cloud infrastructure pipelines.

This skill guides the implementation of comprehensive Identity Governance and Lifecycle Management (IGM) processes. It automates the entire employee identity lifecycle—from pre-hire onboarding (Joiner) to role changes (Mover) and termination (Leaver). Key components include Role-Based Access Control (RBAC) provisioning, periodic access recertification, and remediation of orphaned accounts, ensuring compliance with standards like SOX and GDPR.

This guide details how to implement secure, minimal container bases using Google's distroless images. By leveraging multi-stage builds and eliminating unnecessary OS components like shells and package managers, it drastically reduces the container's attack surface. This technique is essential for enhancing security, meeting compliance standards, and building resilient, production-grade container architectures.

A comprehensive guide for incident responders detailing how to investigate Active Directory (AD) compromises. This skill covers analyzing critical components like NTDS.dit integrity, detecting Kerberos anomalies (Golden/Silver Tickets), tracing lateral movement, and identifying Group Policy abuse to reconstruct attacker activity and determine the full scope of a breach.

A comprehensive tool suite designed to analyze firmware images from embedded devices, including routers, IoT endpoints, and critical system components like UEFI/BIOS. It facilitates deep security analysis by performing firmware extraction, filesystem integrity checks, binary reverse engineering, and sophisticated detection of bootkits, backdoors, and unauthorized modifications.

Perform comprehensive security assessments for Google Cloud Platform environments. This tool audits critical security components—including IAM policies, firewall rules, and storage permissions—against industry benchmarks like the CIS GCP Foundations Benchmark. It helps organizations establish secure baselines and ensure continuous compliance across multiple GCP projects.

A deep dive toolset for forensic investigation of advanced persistent threats (APT) at the firmware level. It analyzes UEFI variable modifications, SPI flash implants, Secure Boot bypass techniques, and unauthorized components within the EFI System Partition (ESP). Utilizes tools like chipsec, flashrom, and YARA for comprehensive integrity verification.

A comprehensive guide detailing the workflow for firmware reverse engineering. It uses tools like binwalk to identify embedded filesystems (e.g., SquashFS, CramFS), perform entropy analysis to locate hidden data, and extract components. The process covers deep inspection, credential discovery, and reporting for IoT and embedded security assessments.

This guide details how to implement secure, keyless software signing using the Sigstore ecosystem components (Cosign, Fulcio, Rekor). It establishes cryptographic provenance for container images and binaries by binding identity via OIDC, ensuring verifiable integrity and tamper-proofing throughout the CI/CD supply chain.

A comprehensive guide detailing the systematic process for upgrading and migrating CAST AI components. This includes updating Helm charts (agent, controller, evictor) and Terraform providers. It outlines prerequisites, step-by-step upgrade procedures, validation checks, and necessary rollback procedures to ensure a safe transition between versions.

This guide details the process of packaging and evaluating academic artifacts for ACM CCS conferences. It outlines the criteria for earning specific ACM badges (e.g., Functional, Reusable, Results Reproduced) by ensuring that supporting evidence—such as exploits, defenses, and measurement pipelines—is turnkey, reproducible, and rigorously documented for the review committee. It covers best practices for artifact planning, handling sensitive material, and justifying any withheld components.

A comprehensive guideline for establishing and documenting the reproducibility of complex sensor-systems artifacts. It covers necessary components such as firmware sources, detailed hardware Bills of Materials (BOMs) and board files, raw sensor traces, ground truth data, and calibrated measurements. Use this guide to ensure that scientific claims can be verified by a competent reader, detailing the exact dependencies on physical equipment and software toolchains.
