What is the recommended CPU configuration for the Nessus scanner?

The recommended CPU configuration for the Nessus scanner is four 2GHz cores. This configuration strikes a balance between performance and resource availability, allowing the scanner to operate efficiently while handling multiple tasks. The four cores provide sufficient processing power to execute scans, manage data collection, and handle concurrent requests, which is particularly important in environments where multiple assets are being evaluated. This setup helps ensure that scanning tasks do not become a bottleneck, allowing for timely vulnerability assessments and quicker response times to security issues.

Selecting fewer cores than recommended, while possibly sufficient in certain limited-use scenarios, risks reduced performance and longer scan times, which can affect the overall effectiveness of vulnerability management efforts. Similarly, while a configuration with more cores could enhance performance, it may not be necessary for all environments and could lead to unnecessary resource allocation and costs. Thus, four 2GHz cores are optimal for balancing capability and efficiency in most use cases.
