What security measure involves continually updating software to protect against vulnerabilities?

The correct answer is patch management because it refers to the process of regularly updating software to address vulnerabilities and improve security. When software vendors identify security flaws, they often release updates or "patches" that fix these issues. Implementing a robust patch management strategy ensures that systems are consistently updated, reducing the risk of exploitation by malicious entities. This proactive approach helps maintain the integrity of software and enhances overall cybersecurity posture.

The continuous updating aspect of patch management is essential, as many cyber attacks exploit unpatched vulnerabilities. Organizations that prioritize patch management can protect their systems from malware, ransomware, and other threats stemming from outdated software.
