Data processing

The set of steps used to collect, clean, transform, and organize raw data into a structured, usable form

The Explain card

Plain English
Data processing is the sequence of steps that takes raw data and collects, cleans, transforms and organises it into a structured form a model can actually use.
Example
Before training a log anomaly detector, a pipeline parses raw syslog, normalises timestamps, masks IP addresses, and converts everything to numeric features.
Why it matters
Every processing step is a place where data can be altered, dropped or injected. Attackers who reach the pipeline can poison training data without ever touching the model.
Hook
Raw in, model-ready out, and every step in between is an attack surface.

Models are only as good as their data — understand the raw material and the engineering that shapes it before covering how it flows or breaks.
