Which of the following describes the most effective way to address OS vulnerabilities after they are identified?

Patching is the most effective way to address OS vulnerabilities because it directly applies fixes released by the vendor to close security holes. These patches often contain code that corrects flaws, preventing exploitation. Endpoint protection (like antivirus) is a layer of defense but doesn't fix the underlying OS vulnerability; it primarily detects and prevents known threats. Removal of unnecessary software reduces the attack surface but doesn't address vulnerabilities in the remaining essential OS components. Configuration enforcement ensures systems adhere to security baselines but doesn't fix inherent software flaws that patching addresses.
