CompTIA Linux+ XK0-006 (V8) Practice Question

The correct answer is CIS Benchmarks. The Center for Internet Security (CIS) Benchmarks are globally recognized, consensus-driven best practices for securely configuring IT systems, software, networks, and cloud infrastructure. They provide prescriptive, step-by-step guidance for system hardening that is accepted by governments, businesses, and academic institutions. Adhering to CIS Benchmarks helps organizations meet compliance requirements for frameworks like PCI DSS, HIPAA, and NIST.

• OpenSCAP is a tool used to automate the process of auditing, vulnerability scanning, and checking for compliance against security policies like the CIS Benchmarks, but it is not the benchmark or standard itself.
• The /etc/sudoers file is a critical configuration file for managing user privileges via sudo, but it only represents a small part of a comprehensive system hardening strategy.
• AIDE is a file integrity checker used to detect unauthorized modifications to system files, which is a component of security auditing, but it does not provide prescriptive configuration baselines for system hardening.
