In my last blog , I’ve provided an example of this happening, whereby the traffic spiked and quadrupled the usual incoming traffic. These are all interesting metrics from marketing point of view, and also highly interesting to you as they allow you to engage with the teams that are driving the traffic against your IT-system.

For example, an organization might use security analytics tools to monitor user behavior and network traffic. Teams can then act before attackers have the chance to compromise key data or bring down critical systems. This data helps teams see where attacks began, which systems were targeted, and what techniques attackers used.

Closed loop” refers to the continuous feedback loop in which the system takes actions — based on monitoring and analysis — and verifies the results to ensure complete problem remediation. The goal is to either improve or restore the system to its optimally functioning state. Ideally, this all occurs without human intervention.
