This comprehensive guide provides scripts and best practices for auditing, hardening, and enforcing AWS Identity and Access Management (IAM) policies. It covers implementing least privilege, defense in depth, and auditing for overly permissive actions, unused roles, and outdated access keys, significantly enhancing cloud security posture.

A comprehensive guide detailing systematic strategies and patterns for optimizing cloud spending across major platforms including AWS, Azure, and GCP. It covers best practices for rightsizing resources, leveraging reserved instances, implementing lifecycle policies, and setting up robust cost governance, ensuring cost efficiency without sacrificing performance or reliability.

This guide provides a comprehensive framework for minimizing cloud expenditure on Databricks. It covers identifying cost drivers via system billing tables, implementing cluster policies, utilizing spot instances for batch processing, right-sizing SQL warehouses, and automating the shutdown of idle development clusters. Use it when managing cloud spending or optimizing data platform usage.

A comprehensive guide for establishing robust, enterprise-grade access control within Databricks. Covers implementing Single Sign-On (SSO) via SCIM, leveraging Unity Catalog for fine-grained Role-Based Access Control (RBAC), defining cluster policies, and enforcing data governance measures like Row-Level Security (RLS) and column masking. Essential for large-scale, secure data platforms.

Comprehensive patterns and best practices for deploying and managing microservices using the Linkerd service mesh on Kubernetes. Covers automatic mTLS, sophisticated traffic splitting for canary deployments, setting Service Profiles for enhanced resilience (retries/timeouts), and defining robust authorization policies.

A comprehensive guide and set of scripts to systematically audit AWS S3 buckets for security misconfigurations. This tool identifies publicly exposed data, overly permissive ACLs, inadequate bucket policies, and missing encryption settings, ensuring adherence to least-privilege principles and compliance frameworks like SOC 2 or HIPAA.

This guide details the implementation of Microsoft's Enhanced Security Admin Environment (ESAE) tiered model for Active Directory. It covers best practices for establishing Tier 0/1/2 separation, deploying Privileged Access Workstations (PAWs), and designing robust access control policies. Ideal for security architects and compliance officers seeking to meet stringent standards like NIST 800-53.

This guide details the process of configuring microsegmentation policies to enforce least-privilege access between workloads. It covers the entire workflow, from application dependency mapping and discovery (Phase 1) to defining label-based, default-deny security zones (Phase 2). It is crucial for preventing lateral movement in highly secure, zero-trust architectures using tools like VMware NSX, Illumio, and Calico.

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.

Provides a comprehensive guide to configuring pfSense firewall rules, NAT policies, and VPN tunnels. It details best practices for enforcing network segmentation (DMZ, LAN, Guest, IOT), controlling traffic flow, and protecting internal network zones in SMB and enterprise environments. Covers VLAN setup, DHCP/DNS management, and granular access control.

This skill guides the advanced configuration of Windows Event Logging using Group Policy Objects (GPO) and advanced audit policies. It enables high-fidelity logging for critical security events, including process creation (Event 4688), logon/logoff activities, and object access. The process covers optimizing log sizes and implementing Windows Event Forwarding (WEF) to centralize data into SIEM platforms for effective threat detection and forensic investigation.

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).
