A comprehensive guide for deploying Cisco Duo Multi-Factor Authentication across diverse enterprise access points, including VPN, RDP, SSH, and web applications. This skill details advanced security practices, covering adaptive access policies, phishing-resistant authentication (WebAuthn/FIDO2), device health checks, and establishing robust identity and access management controls aligned with industry compliance standards.

This comprehensive guide details the architecture and implementation of VLAN-based network segmentation on managed switches. It teaches professionals how to isolate different network zones (e.g., corporate, DMZ, IoT) to enforce strong access controls, reduce the attack surface, and meet compliance standards like PCI-DSS. The workflow includes designing the VLAN plan, configuring trunking, hardening switches against VLAN hopping, and setting up inter-VLAN routing with ACLs.

This skill provides comprehensive guidance and PowerShell scripts for hardening Windows endpoints using Microsoft Defender for Endpoint (MDE). It covers advanced features like Attack Surface Reduction (ASR) rules to block common attack techniques, Controlled Folder Access for ransomware protection, and Network Protection. Use this for deploying enterprise-grade, compliance-required security policies via Intune or Group Policy.

This guide details the process of implementing Zscaler Private Access (ZPA) to replace legacy VPNs with a modern Zero Trust Network Access (ZTNA) framework. It covers deploying App Connectors, defining application segments, and establishing granular access policies based on user identity, organizational user groups, and detailed device posture checks (e.g., compliance, anti-malware status).

A comprehensive guide to deploying and configuring osquery across diverse endpoints (Windows, macOS, Linux). This tool allows security teams to gather deep, SQL-based insights into endpoint state, including running processes, network connections, system configuration, and installed software. It is essential for threat hunting, compliance auditing, and building centralized fleet visibility.

A comprehensive solution for identifying and preventing the accidental commitment of exposed AWS credentials, API keys, and session tokens within source code, configuration files, and git history. It integrates TruffleHog and git-secrets into CI/CD pipelines and pre-commit hooks, providing critical protection against credential theft and unauthorized cloud access in a DevSecOps environment. Essential for security auditing and compliance.

This tool provides a comprehensive security audit framework for Azure Storage accounts. It systematically detects critical misconfigurations, such as publicly accessible blob containers, weak encryption settings, overly permissive network access rules, and missing logging. Use it when performing compliance checks, responding to security incidents, or establishing storage security baselines in Azure environments.

A comprehensive guide and workflow for detecting unauthorized data exfiltration from AWS S3 buckets. It details how to leverage multiple AWS services—including CloudTrail, GuardDuty, Amazon Macie, and Athena—to analyze access patterns, identify bulk downloads, and detect cross-account data transfers, ensuring robust cloud compliance and security monitoring.

This skill provides a methodology for proactive threat hunting to detect compromised service accounts. It focuses on identifying anomalous activities such as unusual interactive logons, unauthorized privilege escalation, lateral movement, and suspicious access patterns using SIEM/EDR platforms. Essential for incident response and compliance.

This skill analyzes network logs, including proxy access logs, DNS query logs, and netflow data, to detect unauthorized Software as a Service (SaaS) applications and cloud services (Shadow IT). It classifies domains against known catalogs, measures data exfiltration volumes, calculates risk scores, and generates comprehensive reports for security and compliance teams.

This skill automates the hardening of Linux endpoints (Ubuntu, RHEL, CentOS) by implementing industry-standard security best practices guided by CIS Benchmarks. It systematically secures various layers, including filesystem permissions, network parameters (sysctl), SSH configuration, user access controls (PAM), and integrates deep auditing using auditd and OpenSCAP. It is essential for achieving compliance with standards like PCI DSS, HIPAA, and SOC 2.

This skill guides the security hardening of Windows endpoints (10/11, Server 2019/2022) using established CIS Benchmarks. It provides a comprehensive workflow for establishing secure organizational baselines, configuring Group Policy Objects (GPOs), and enforcing security controls across critical areas like password policies, audit logs, and firewall rules. It is essential for achieving compliance with standards like PCI DSS, HIPAA, and SOC 2.
