Step-by-step explanation:
For guidance on hardening a Linux system, reviewing official Linux distribution documentation (Option C) is the most reliable and recommended source. Linux distributions typically provide comprehensive and up-to-date documentation that covers security best practices, configuration options, and guidelines for securing the system.
Official Linux distribution documentation serves as a trustworthy resource because it is maintained by the developers and maintainers of the Linux distribution. It includes detailed information on securing various aspects of the system, such as user accounts, network settings, file permissions, and kernel security. Relying on official documentation ensures that the guidance is accurate, relevant to the specific distribution, and aligns with industry best practices for Linux system hardening.
Contrastingly, random online forums and blogs (Option D) may contain outdated or inaccurate information, and the credibility of the advice may vary. While some online resources can be valuable, they should be approached with caution, as the information may not be verified or may not apply to the specific Linux distribution in use. Therefore, for a secure and reliable approach to hardening a Linux system, consulting the official documentation of the chosen distribution is the most prudent choice.(otpion C)
