What should an organization prioritize to mitigate the dangers of zero-day vulnerabilities?

Prioritizing regular software updates and monitoring is crucial for mitigating the dangers associated with zero-day vulnerabilities. Zero-day vulnerabilities are security flaws that are exploited by attackers before the vendor has released a fix or patch. By keeping software up to date, organizations can ensure they apply patches and updates as soon as they are available, effectively closing off potential entry points that attackers could exploit.

Regular monitoring enhances the organization’s ability to detect unusual patterns or behaviors that may indicate exploitation of any unknown vulnerabilities. This proactive approach allows for quicker responses and remedial actions, reducing the potential impact of successful attacks on the organization's network and data.

In contrast, other options such as hiring more customer service staff, reducing email attachment sizes, or increasing physical security are not directly effective strategies for addressing the specific threat posed by zero-day vulnerabilities. While these might contribute to broader security or operational efficacy, they do not address the need for timely updates and vigilant monitoring that are essential in guarding against such vulnerabilities.
