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?

While patching is essential for maintaining system security and performance, addressing non-compliant OS baselines is a more immediate concern in this situation. Patching should be done after isolating the affected machines to ensure that they are up to date and secure.

Segmentation is useful for separating network traffic and isolating different parts of the network. However, in this case, the priority is to isolate the affected machines to prevent the spread of viruses and address the performance issues caused by non-compliant OS baselines.

Monitoring is crucial for identifying security incidents and performance issues, but in this scenario, immediate action is needed to contain the security threat and address the performance issues. Isolating the affected machines takes precedence over monitoring in this situation.
