The Practical Linux Hardening Guide
This project is a comprehensive Linux server hardening guide and infrastructure documentation resource. It provides a set of validated security baselines and step-by-step instructions for implementing security controls and configuration best practices to protect production environments.
The guide focuses on aligning systems with industry-standard security benchmarks, specifically those provided by the Center for Internet Security and Security Technical Implementation Guides. It includes a framework for using OpenSCAP to scan system configurations, verify compliance against reference profiles, and generate detailed auditing reports.
The documentation covers the application of strict directory permissions, the implementation of standardized security baselines, and the use of automation tools to consistently apply hardening workflows across multiple servers.
