A new study reports that changing how intrusion detection data is prepared before it reaches an AI model can lift detection accuracy by as much as 22.9 percentage points, without touching the model itself.
The researchers argue that intrusion detection systems have long suffered from a hidden flaw in their data pipelines.
First, it classifies each feature into one of six semantic groups: temporal, volumetric, behavioral, identity, protocol-specific, or statistical.
Behavioral, identity, protocol-specific, and statistical features, which are bounded or sparse, receive min-max scaling that preserves their original zero-to-one or ordinal structure.
