Abstract: Using labelled training content, a content classification model is trained. Using the trained content classification model, a label describing a first content is determined. The first content is classified into a category in a set of categories using the label. Responsive to the first content being classified into a category of inappropriate content, the first content is removed from a storage location.

Abstract: A hardware functional module sends, to an aggregation module and in a standardized message format, first status information associated with the hardware functional module according to a first set of reporting rules via a first dedicated link. The firmware functional module sends, to the aggregation module and in the standardized message format, second status information associated with the firmware functional module according to a second set of reporting rules via a second dedicated link. The aggregation module aggregates the first status information in the standardized message format and the second status information in the standardized message format and inserts a timestamp to obtain a timestamped and aggregated message stream. The timestamped and aggregated message stream enables a visualization system to analyze the hardware functional module and the firmware functional module.
