Skill UI

An expert in designing, implementing, and optimizing scalable, reliable, and cost-effective data pipelines for both batch and streaming data. Covers advanced topics including ETL/ELT patterns, Kappa/Lambda architectures, workflow orchestration (Airflow/Prefect), transformation using dbt/Spark, and managing modern storage formats like Delta Lake and Iceberg. Focuses heavily on data quality, monitoring, and cost optimization strategies.

This guide outlines the process of passive external reconnaissance using Open Source Intelligence (OSINT) techniques. Users can map an organization's digital footprint by gathering comprehensive data, including DNS records, subdomains, certificate transparency logs, social media profiles, and leaked credentials. It is critical for the planning phase of penetration testing, asset mapping, or preparing for social engineering, all without actively interacting with target systems.

This guide details the deployment of Cisco Identity Services Engine (ISE) for comprehensive Network Access Control (NAC). It utilizes 802.1X authentication, MAC Authentication Bypass (MAB), and posture assessment to enforce security policies. Key features include integrating with Active Directory, assigning dynamic VLANs, and applying TrustSec Security Group Tags (SGTs) for advanced network segmentation in enterprise environments.

A comprehensive guide to securing Software as a Service (SaaS) applications (e.g., Microsoft 365, Salesforce) using Zero Trust principles. This skill covers deploying CASB/SSPM solutions, enforcing conditional access policies (MFA, device compliance), governing OAuth permissions, and applying session-level DLP controls to prevent data exfiltration in multi-cloud environments. Ideal for security architects and engineers.

Open Source Intelligence (OSINT) is the critical first phase of red team engagements. This guide details how to systematically collect publicly available data about a target organization. It covers mapping network assets (domains, IPs), identifying personnel for social engineering, discovering credential leaks, and mapping the entire technology stack. Use this skill during authorized security assessments to build comprehensive attack surface maps and initial access strategies.

This comprehensive guide teaches advanced iOS reverse engineering techniques using Frida dynamic instrumentation. Users can analyze proprietary app logic, extract encryption keys, trace method calls, and bypass anti-tampering or anti-debugging mechanisms without needing source code. It is essential for authorized mobile security testing and protocol analysis.

This guide details how to implement Identity-Aware Proxy (IAP) using gcloud. It enforces per-request identity verification and context-aware access policies (e.g., device posture, location) across major GCP backends, including Compute Engine, App Engine, Cloud Run, and GKE. It is essential for migrating from traditional VPN access to a robust, zero-trust, identity-based security architecture for cloud applications.

This guide details how to mature and operationalize a MISP instance, transforming it from a simple repository into an active threat detection engine. Users learn to enable and cache curated threat feeds, apply warninglists to minimize false positives, query indicators using PyMISP, and automate the export of matching attributes into industry-standard detection rules like Suricata, Sigma, and Wazuh.

A comprehensive guide for authors targeting high-impact chemical engineering venues. It helps authors re-frame their work from simple material synthesis to demonstrating an applied advance with clear mechanistic insight. Focus areas include catalysis, separation, functional materials, and performance benchmarking under realistic process conditions.

This detailed guide helps authors assess the scientific rigor and scope fit for manuscripts targeting Composites Part B: Engineering. It covers advanced domains like composite mechanics, manufacturing processes, multiscale modeling, and multifunctional materials. It emphasizes that a strong contribution must demonstrate a clear, mechanism-driven advance from material science to structural application, supported by rigorous, quantitative experimental evidence and model validation.
