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.

This skill empowers users to manage and monitor critical SSL/TLS certificates using the built-in certificate manager. It provides capabilities to check certificate expiration dates, automate the renewal process for expired credentials, and list all installed certificates. It is essential for system administrators and developers maintaining secure, uninterrupted network connections and ensuring compliance.

A comprehensive guide to simulating Man-in-the-Middle (MITM) attacks using industry-standard tools like Bettercap, Ettercap, and mitmproxy. This technique is strictly for authorized penetration testing environments to assess cryptographic controls, validate TLS certificate pinning, and test network defense mechanisms against ARP/DNS spoofing and sniffing.

A comprehensive guide to deploying and configuring Suricata as a high-performance Intrusion Detection System (IDS) or Intrusion Prevention System (IPS). This skill covers setting up multi-threaded packet processing for high-throughput links, enabling protocol-aware inspection (HTTP, TLS, DNS, SMB), generating structured EVE JSON logs for SIEM ingestion, and integrating advanced signature and anomaly detection capabilities.

A comprehensive guide to implementing and validating Transport Layer Security (TLS) 1.3. This skill covers configuring modern cipher suites, key exchange groups, and enforcing perfect forward secrecy (PFS). Use this when deploying secure communication protocols, hardening network services, meeting compliance standards, or performing deep security assessments on web servers and applications.

This skill provides a comprehensive guide to deploying a Software-Defined Perimeter (SDP) compliant with the CSA v2.0 specification. It details implementing core zero trust mechanisms, including Single Packet Authorization (SPA) and mutual TLS (mTLS), using a controller and gateway architecture. Use this when establishing invisible, identity-centric network access (dark cloud) to harden infrastructure, enforce strict zero trust policies, or meet advanced compliance requirements.

This guide details how to harden the Docker daemon (dockerd) configuration by modifying /etc/docker/daemon.json. It implements critical security controls such as user namespace remapping, disabling inter-container communication (ICC), enforcing no-new-privileges, and configuring secure TLS client authentication. Use this method to prevent container breakout, privilege escalation, and lateral movement, ensuring compliance with standards like CIS benchmarks.

A comprehensive guide for implementing a highly secure and reliable centralized logging pipeline using rsyslog. This method utilizes TLS encryption via X.509 certificate authentication and GnuTLS stream drivers, ensuring all log data is securely transmitted. The guide covers per-host log segregation, robust log rotation, and disk-assisted queueing for high-availability log infrastructure, making it ideal for compliance and security operations.

Provides a comprehensive guide to auditing the security posture of the etcd cluster, the critical key-value store backing Kubernetes. This assessment covers encryption at rest for secrets, TLS transport security, access control policies, secure backup procedures, and network isolation best practices. Essential for hardening control planes and ensuring regulatory compliance.

Zeek is a powerful, open-source network analysis framework that functions as a passive security monitor. It generates highly detailed, structured logs (e.g., HTTP, DNS, TLS) from raw network traffic, allowing for deep metadata extraction. This skill guides users through deploying Zeek, writing custom detection scripts, and integrating the resulting rich security logs with SIEM platforms for advanced threat detection and forensic investigations.

This skill covers the technical process of setting up SSL/TLS inspection (decryption) on next-generation firewalls and proxies. It details how to act as a trusted Man-in-the-Middle to intercept, decrypt, and inspect encrypted HTTPS traffic for malicious payloads, data exfiltration, and policy violations. The workflow includes generating internal Certificate Authority (CA) certificates and deploying them across various operating systems (Windows, macOS, Linux) to ensure visibility into the web's encrypted blind spot.

This skill assesses SSL/TLS server configurations using the sslyze Python library. It evaluates critical security parameters including supported protocol versions (TLS 1.0-1.3), cipher suite strength, certificate chain validation, HSTS enforcement, and known vulnerabilities like Heartbleed and ROBOT. Essential for security audits and compliance testing.
