Choose the Right Detection and Labeling Method

Choose the Right Detection and Labeling Method

This applied lesson develops exam and operational judgment for choose the right detection and labeling method.

Detection method follows the shape of the evidence

Use built-in or custom SITs for structured patterns with supporting evidence. Use EDM for exact governed values, document fingerprinting for stable forms, and trainable classifiers for document-level meaning. A keyword or regex alone is often weak proof.

Ask what a false positive disrupts and what a false negative exposes. Test true examples, close negatives, different formats, edge cases, workloads, and languages. The expected answer should be written before tuning. The custom SIT tuning guide shows how proximity, evidence, confidence, and exclusions work together.

Prefer answers that preserve detector versions, evaluation results, intended policies, and an owner for drift.

Labels turn business meaning into handling

A label taxonomy should be small enough to understand and distinct enough to change behavior. File labels can travel with content and apply marking or encryption. Container labels govern supported site or group settings. Publishing policies determine availability and defaults; auto-labeling connects validated evidence to an outcome.

Before enforcing encryption, test guests, coauthoring, search, mobile, offline use, eDiscovery, and integrations. Before auto-labeling, simulate and obtain owner approval. The sensitivity-label design guide provides the complete decision model.

Exam distractors often assume a site label stamps every file or that creating a label publishes it automatically. Both assumptions are unsafe.
