The help desk receives multiple calls indicating that machines are running slowly when running enterprise applications. The help desk notes that the affected machines are out of compliance with the organization's OS baselines. Several users also report receiving virus detection alerts. Which of the following mitigation techniques should the help desk consider first?

Patching involves updating the software to fix vulnerabilities, which is essential but may not address the immediate risk posed by the infected machines. If the machines are already compromised, applying patches without isolating them could allow malware to continue spreading or operating undetected, thus potentially worsening the situation.

Segmentation involves dividing the network into smaller parts to limit the spread of threats. While this could be a long-term strategy to enhance security, it does not immediately address the infections present on the machines. Therefore, it is not the best first step in response to the current situation where machines are already showing signs of infection.

Monitoring systems can provide valuable insights into the health and performance of machines, but it does not actively mitigate the risks. In this scenario, users are already reporting issues, so simply monitoring the situation without taking immediate action would not resolve the pressing concerns of slow performance and virus alerts.
