Which of the following provides the BEST software risk remediation methods?

Comprehensive and Detailed Explanation (250–350 words)

===========

The EC-Council CCISO program defines effective software risk remediation as actions that reduce exposure by eliminating vulnerabilities and unnecessary attack surface. The most effective remediation methods are installing patches and updates, adjusting configurations, and removing unnecessary or unsupported software.

CCISO documentation emphasizes that vulnerabilities are most commonly addressed through patch management, secure configuration, and software decommissioning. Adjusting insecure default configurations and removing obsolete software directly reduce exploitable weaknesses.

Other options either include non-remediation activities (defining requirements, discovering software) or incomplete approaches that do not fully address risk. CCISO aligns remediation best practices with NIST and ISO vulnerability management guidance.

Therefore, Option C is correct.
