This guide details how to use Kubernetes NetworkPolicies to enforce granular, pod-level network segmentation. It covers establishing default deny rules, defining specific ingress and egress rules for services, and implementing zero-trust microsegmentation. Use this skill to build robust security architecture and prevent lateral movement within a container cluster.

This skill provides a comprehensive guide for designing and deploying Privileged Access Workstations (PAWs). It covers critical security controls such as device hardening, Zero Trust principles, and integrating Just-in-Time (JIT) access management. Learn how to enforce compliance using tools like Intune/GPO and secure credentials using leading PAM platforms like CyberArk or BeyondTrust, ensuring secure administrative operations.

Configure Azure AD Privileged Identity Management via Microsoft Graph API to enumerate eligible and active assignments, request just-in-time activations, audit logs, and enforce MFA or approval policies for zero-trust privileged access scenarios.

This comprehensive guide details the deployment of HashiCorp Vault for robust, centralized secrets management in hybrid and multi-cloud environments. It covers configuring dynamic secret engines for databases (PostgreSQL) and cloud providers (AWS), integrating diverse authentication methods (OIDC, AppRole, Kubernetes), and securely delivering short-lived secrets to Kubernetes workloads via agents. The primary goal is to enforce zero-trust principles by eliminating hardcoded, long-lived credentials from application code and CI/CD pipelines.

This skill guides the implementation of Security Orchestration, Automation, and Response (SOAR) workflows using platforms like Splunk Phantom. It automates the entire incident lifecycle, including alert triage, IOC enrichment (via VirusTotal, CrowdStrike), containment actions, and ticket creation (ServiceNow). Ideal for SOC teams needing to reduce Mean Time To Respond (MTTR) and standardize complex security procedures across multiple tools.

This skill provides a comprehensive guide to integrating STIX (Structured Threat Information eXpression) and TAXII (Trusted Automated eXchange of Intelligence Information). It covers using Python to consume and produce cyber threat intelligence feeds, including server discovery, object fetching, and parsing of STIX 2.1 objects for integration into SIEM and TIP platforms.

Build a PyMISP-driven threat intelligence platform that ingests multiple IOC feeds, tags MITRE ATT&CK techniques, enriches data via VirusTotal and AbuseIPDB, and exports STIX 2.1 bundles for SIEM pipelines.

This guide details how to implement NextDNS as a zero-trust DNS filtering layer. By utilizing encrypted resolution (DoH/DoT) and real-time threat intelligence, it blocks malicious domains, prevents data exfiltration, filters ads/trackers, and enforces granular security policies across all endpoints, aligning with Zero Trust principles and enhancing overall network security.

This guide details the implementation of Zero Trust Architecture for securing Software as a Service (SaaS) applications. It leverages Conditional Access Policies, CASB (Cloud Access Security Broker), and Identity Governance to enforce strict identity verification, device compliance, and data loss prevention (DLP) across cloud environments (e.g., M365, Salesforce). It helps mitigate risks associated with shadow IT and excessive application permissions.

This comprehensive guide details the implementation of Zero Trust Architecture (ZTA) in multi-cloud environments (AWS, Azure, GCP). Following NIST SP 800-207 and BeyondCorp principles, it covers identity-centric access controls, micro-segmentation, continuous verification, and deploying Identity-Aware Proxies (IAP) to eliminate implicit network trust.

A comprehensive guide to implementing Zero Trust Network Access (ZTNA) across major cloud platforms (AWS, Azure, GCP). This skill replaces traditional VPNs with identity-aware proxies, micro-segmentation, and conditional access policies. It ensures secure, context-aware access to cloud workloads, limiting lateral movement and adhering to BeyondCorp architectural principles.

This skill guides the end-to-end deployment of Zero Trust Network Access (ZTNA) using Zscaler Private Access (ZPA). It replaces traditional, perimeter-based VPNs by enforcing identity-based, context-aware microsegmentation. Learn to configure Identity Provider integration, deploy App Connectors, define granular application segments, and establish robust access policies for secure, outbound-only connections.
