In the context of data analysis platforms like Malcolm, (short for Aggregation) and Top are fundamental concepts used to distill vast amounts of network traffic into actionable intelligence:

This refers to the process of grouping individual data points—such as IP addresses, protocols, or port numbers—to identify patterns. Malcolm utilizes Field Aggregations to summarize network events, making it easier to spot anomalies.

Quickly drill down into the most suspicious "top" alerts to find the root cause of a breach.
