What is indicated by a decrease in CPU usage shown in the outcome of an IPS diagnostic command?

A decrease in CPU usage as shown in the outcome of an IPS (Intrusion Prevention System) diagnostic command typically indicates that less traffic is being inspected by the IPS engine. When the IPS engine encounters a lower volume of traffic or fewer potential threats to analyze, it requires less processing power, leading to a reduction in CPU usage. This situation can occur during periods of low network activity, when fewer IPS rules are being triggered, or when benign traffic patterns dominate which do not require in-depth inspection.

Understanding this relationship is crucial for network administrators. Monitoring CPU usage is an important part of evaluating the performance and efficiency of the IPS system. A significant drop may suggest that the IPS is effectively handling the current traffic load, enhancing overall performance and responsiveness.

Other options may present plausible scenarios but do not specifically align with the direct implications of CPU usage decrease in the context of IPS. For instance, while balanced workloads can affect performance positively, they do not directly correlate with CPU usage reduction. Similarly, updates to security policies primarily focus on the rules and threats being monitored rather than on the current load being processed by the IPS engine itself. Lastly, the assertion that the IPS engine is malfunctioning would typically correlate with an increase in CPU usage due to it struggling to process traffic effectively
