Diagnose falling malicious-webpage warnings by decomposing traffic, scoring, flags, rendering, and labels to separate improvement from failure.
Investigate a Decrease in Webpage Warnings
A system that warns users about malicious webpages shows a decrease in the number of warnings displayed. How would you investigate? Explain how you would distinguish an improvement in safety from a detection, delivery, or measurement problem, and what evidence would guide the next action.
Hints
Hint 1
Follow a browsing encounter: A malicious page can be missed because it was never scored, not flagged, not rendered, or not logged.
Follow-up questions
- What would you conclude if flags stayed constant but displayed warnings fell?
- How would you estimate whether false negatives increased?
