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 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.

This skill covers implementing robust API rate limiting and throttling controls using advanced algorithms like token bucket and sliding window. It teaches how to protect backend systems against attacks such as brute force, credential stuffing, and resource exhaustion. Key components include configuring limits per user, per IP, and per endpoint, utilizing Redis for distributed counting, and implementing proper HTTP 429 responses for effective abuse prevention.

API Security Posture Management (API-SPM) provides continuous, unified visibility into an organization's entire API attack surface. It automatically discovers, classifies, and risk-scores all APIs—including internal, external, and shadow endpoints. By aggregating findings from various sources (DAST, SAST, runtime logs), it helps enforce security policies, detect configuration drift, and maintain compliance across the entire API lifecycle.

Learn how to implement robust container security by integrating the open-source Trivy scanner (from Aqua Security) into your CI/CD pipelines. This guide covers scanning container images, Kubernetes manifests, IaC files, and code repositories to detect critical vulnerabilities, misconfigurations, secrets, and generating Software Bill of Materials (SBOM) for comprehensive supply chain security.

This skill details how to establish continuous compliance monitoring for AWS resources. It covers deploying managed and custom Config rules aligned with industry standards like CIS and PCI DSS. The workflow includes setting up recording, implementing automated remediation using SSM, and aggregating compliance data across multiple AWS accounts using AWS Organizations. Ideal for security auditing and guardrail deployment.

A comprehensive guide to implementing AWS Security Hub for centralized security posture management. It enables the aggregation of findings from multiple AWS accounts, evaluates compliance against industry standards (like CIS, PCI DSS, NIST), and configures automated remediation workflows using EventBridge and Lambda for robust organizational risk management.

This guide details the implementation of Microsoft Defender for Cloud, enabling comprehensive cloud security posture management (CSPM) and workload protection (CWPP). Learn how to secure VMs, containers, databases, and storage accounts, configure security recommendations, and establish automated remediation workflows to ensure continuous compliance and robust cloud defense.

This guide details the process of implementing BGP route origin validation using Resource Public Key Infrastructure (RPKI). Learn how to create Route Origin Authorizations (ROAs), deploy RPKI validators, and configure Route Origin Validation (ROV) on major routers like Cisco IOS-XE and Juniper Junos. This technique is crucial for preventing malicious route hijacking and securing internet routing paths.

A comprehensive guide for implementing Cloud Security Posture Management (CSPM) across multi-cloud environments (AWS, Azure, GCP). Learn how to use specialized tools like Prowler and ScoutSuite, combined with native cloud services (Security Hub, Defender, SCC), to continuously monitor for misconfigurations, compliance violations (CIS, SOC 2), and security drifts, thereby enforcing security guardrails in complex cloud architectures.

A comprehensive guide on implementing AWS CloudTrail log analysis for robust security monitoring, threat detection, and forensic investigation. Learn how to configure CloudTrail, use Amazon Athena for SQL querying, and leverage CloudWatch Logs Insights and SIEM integration to identify unauthorized access, privilege escalation, and suspicious API activity across AWS services.
