Which configuration guides can be downloaded for free and include detailed descriptions of configuration points for system hardening?

The correct choice is CIS Benchmark because it provides a comprehensive set of configuration guidelines focused on security best practices for various systems and applications. These benchmarks are designed to assist organizations in achieving a higher level of security by detailing configuration points that can be implemented to harden systems against attacks and vulnerabilities. The CIS Benchmarks are widely recognized and freely accessible, making them an excellent resource for organizations looking to enhance their security posture.

Additionally, the Benchmarks are community-driven, validated by subject matter experts, and cover a wide range of platforms and technologies, emphasizing their usability and relevance. They not only offer detailed descriptions but also provide implementation steps and recommendations based on real-world security challenges, which further aids organizations in systematically improving their defenses.

Other resources listed, while valuable, do not focus as specifically on configuration points for system hardening in the same manner as the CIS Benchmarks. For instance, STIGs are also detailed configuration guides, but they are mainly intended for U.S. Department of Defense systems and may have restrictions on access. NIST 800-84 and NIST 800-207 address broader concepts and standards in security rather than focusing specifically on practical configuration guidance akin to that provided by CIS Benchmark papers.
