When a new vulnerability is discovered in software, thebest way to secure itis byapplying updates (patches)released by the software vendor. According to the CompTIA ITF+ objectives:
“Vendors regularly release software updates and security patches to fix vulnerabilities that could be exploited by attackers. Installing these patches promptly is crucial for maintaining system security.”
Although configuring a firewall and authentication improves overall security, they do not directly patch or fix the vulnerability. Uninstalling may be an option only if a patch is unavailable or the software is no longer needed. Therefore, the best and most proactive response is B: Apply updates.
