What is the most effective way to respond to an attack on a Web server that has vulnerabilities?

Installing software updates for the Web server daemon is the most effective response to an attack on a Web server with vulnerabilities because it directly addresses known security flaws that could be exploited by attackers. Software updates often include patches and fixes for vulnerabilities that have been discovered since the last update. By keeping the server software up to date, you reduce the attack surface and enhance the security posture of the server, making it more resilient against potential exploits.

This proactive approach is crucial in maintaining the integrity and security of web applications, as many attacks target vulnerabilities that have already been addressed by software vendors. Regularly updating server software not only mitigates existing risks but also prepares the environment against new threats that might emerge. In a landscape where cyber threats are constantly evolving, timely updates are a cornerstone of effective web security management.
