Server Hardening and Security Auditing

This is an Ansible collection that automates security hardening for Linux operating systems, databases, web servers, and SSH services. It provides a declarative, modular architecture that enforces idempotent security configurations, ensuring that each task only applies changes when the current system state deviates from the desired security baseline. The collection organizes security configurations into reusable Ansible roles, each targeting a specific system component. It includes roles for hardening OpenSSH with key-only authentication and disabled root login, securing MySQL and MariaDB ins

This project is a collection of automated hardening frameworks and Ansible roles designed to secure Linux systems, databases, SSH services, and web servers. It functions as a configuration framework that reduces the attack surface of Linux distributions through the automated enforcement of security policies. The collection provides specific security baselines for a variety of services, including MySQL databases, OpenSSH daemons, and web servers such as Nginx and Apache. These roles are designed to remove insecure defaults, enforce secure authentication methods, and align system configurations

This project is a security compliance tool and configuration auditor designed to evaluate Docker deployments against industry security benchmarks. It functions as a script-based scanner that identifies misconfigurations and vulnerabilities within both the host operating system and container settings. The tool specifically implements the Center for Internet Security standards for Docker to verify host and container configurations. It enables a hardening workflow by comparing system states against these standards to identify security gaps and document compliance status. The audit engine suppor

Lynis is an automated security auditing and system hardening framework designed for UNIX-based operating systems. It functions as a command-line utility that inspects local system configurations to identify security vulnerabilities, configuration weaknesses, and compliance gaps. By executing a series of modular tests, the tool generates actionable reports and remediation suggestions to assist in strengthening system defenses. The project distinguishes itself through a highly modular architecture that relies on shell-script-based execution and native system inspection. Users can define custom

Windows Hardening is a PowerShell-based automation framework designed for security assessment and configuration management within Windows environments. It provides a suite of administrative utilities to enforce industry-standard security benchmarks, audit system compliance, and reduce the overall attack surface of host machines. The project distinguishes itself by offering specialized capabilities for enterprise-wide configuration management, including the ability to transform security findings into deployable group policy objects. It also integrates system state management, allowing administ

Harden-Windows-Security is a security hardening tool and framework designed to reduce the attack surface of the Windows operating system through policy enforcement. It provides a collection of security presets and templates to implement official hardening standards across multiple devices. The project distinguishes itself through a comprehensive execution control system, featuring a manager for Windows Application Control and a kernel protection suite. It implements strict trust models, including kernel-mode driver whitelisting, signed policy implementation on the EFI partition, and code inte

sysmon-config provides configuration templates and exclusion rule sets designed to standardize system event tracing and reduce log noise on Windows hosts. It functions as a security configuration baseline that establishes a standard for tracing system events and process behaviors. The project focuses on providing pre-defined XML filters to highlight anomalous system changes while minimizing performance impact. It utilizes a collection of exclusion rules to remove trusted processes from event logs, which improves signal quality and reduces the volume of generated security data. These configur

Cloudsploit is a cloud security posture management tool and multi-cloud security auditor. It audits cloud infrastructure for misconfigurations and compliance risks across multiple providers, specifically AWS and Azure, by evaluating resource configurations against a set of security plugins. The project functions as a cloud compliance scanner that maps infrastructure scan results to regulatory frameworks and security policy standards. It also serves as an automated cloud remediation tool, executing corrective actions to fix detected misconfigurations via SDK calls. The system covers resource

Kubescape is a security platform for Kubernetes that provides tools for scanning clusters, configurations, and container images against industry compliance and security benchmarks. It functions as a suite of security utilities, including a compliance auditor, a misconfiguration scanner, and a container vulnerability scanner. The project differentiates itself through automated remediation and active enforcement. It can automatically patch operating system vulnerabilities in images and fix security errors within manifest files. It also utilizes an admission controller to block the deployment of

Prowler is an automated cloud infrastructure security scanner and posture management tool. It evaluates cloud environments and infrastructure-as-code templates against security benchmarks to identify misconfigurations, vulnerabilities, and compliance gaps that could compromise system integrity. The platform distinguishes itself through graph-based attack path analysis, which identifies chains of misconfigurations that create exploitable routes for unauthorized access. It utilizes a plugin-based execution model to perform state-based assessments of live environments and static analysis of conf

Cloud Custodian is a multi-cloud governance engine and policy enforcement tool designed to automate security, compliance, and cost optimization across various cloud providers. It functions as a rules engine that uses a declarative domain specific language to query cloud resources and execute corrective actions based on predefined filters.
