What action will best ensure a database server can withstand a recently discovered vulnerability?

Installing a system update is the most effective action to ensure that a database server can withstand a recently discovered vulnerability. Software updates typically include patches that directly address known security vulnerabilities, making them essential for maintaining the security of the system. By applying these updates, the database server receives specific fixes that eliminate or mitigate the threat posed by the vulnerability, thus enhancing its defense mechanisms.

This approach effectively closes the security gap that may have been exploited by attackers. Regularly updating software is a fundamental practice in cybersecurity, as many vulnerabilities are discovered routinely, and developers release updates to protect users from potential threats. Therefore, ensuring that the database server is kept up to date is crucial for safeguarding sensitive data and maintaining the robustness of the server against attacks.
