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.

A comprehensive guide to optimizing cloud expenditure on the Vercel platform. It details how to understand the Fluid Compute pricing model, identify key cost drivers (such as function execution time, bandwidth, and middleware invocations), and implement best practices like edge caching, memory right-sizing, and aggressive asset caching. Use this when analyzing high Vercel billing, implementing cost controls, or managing a SaaS budget.

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 how to build and manage a robust two-tier Public Key Infrastructure (PKI) using OpenSSL. Learn to establish a Root CA and an Intermediate CA, issue server and client certificates, configure Certificate Revocation Lists (CRLs), and implement best practices for secure key management and certificate policy enforcement, ensuring compliance and high security standards.

This comprehensive guide details how to implement robust security hardening measures for LDAP directory services. It specifically addresses critical vulnerabilities like LDAP injection, anonymous binding, and channel binding bypass. Key features include mandatory LDAPS enforcement, granular access control list configuration, and integrating advanced monitoring to ensure the infrastructure meets high compliance standards (e.g., NIST 800-53). Essential for security architects and operations teams.

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 guide provides comprehensive steps to harden the Docker daemon configuration. It covers essential security controls like user namespace remapping, disabling inter-container communication (ICC), implementing TLS authentication, and adopting rootless mode. Implementing these measures significantly reduces the attack surface and mitigates risks associated with container breakouts and privilege escalation, aligning with CIS benchmarks.

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 implementation of full disk encryption using Microsoft BitLocker on Windows endpoints. It covers best practices for deploying encryption via GPO, Intune, and command line, ensuring data-at-rest protection. Use this when meeting compliance requirements (PCI, HIPAA) or securing mobile workstations against physical loss or theft.

This guide details the implementation of SPF, DKIM, and DMARC—the three core pillars of email authentication. It provides a comprehensive workflow, including DNS record setup and best practices, to prevent domain spoofing, validate message integrity, and enforce strong anti-phishing policies across your organization's email system. Essential for building robust email security architecture.

OPA Gatekeeper is a powerful Kubernetes admission controller that enforces policies using Rego rules. It utilizes ConstraintTemplates and Constraints to validate, mutate, or deny API requests at the cluster admission stage. This tool is essential for implementing policy-as-code practices, ensuring that Kubernetes deployments adhere to organizational security standards, compliance requirements, and best practices, such as mandating labels or blocking privileged containers.

An open-source tool based on the CIS Docker Benchmark. It systematically audits critical security aspects of Docker deployments, including host configuration, daemon settings, and container runtime. It generates a detailed compliance report (pass/fail/warn) to ensure best practices and security compliance in production environments.
