AppSec Bot Challenge — Scoring engine

Part of the appsec-bot-challenge bundles. It serves the browser-fingerprint challenge and weights each fingerprint mismatch signal into a request score — strong automation signals like webdriver / cdp score 100, down to weak signals like utc_timezone scoring 5.

What it contains

• appsec-bot-challenge-scoring — serves the challenge and computes the weighted request score.

On its own it never rejects; it only challenges and scores. Pair it with a threshold config that decides when a submission is rejected:

• appsec-bot-challenge-scoring-strict — reject at score >= 45
• appsec-bot-challenge-scoring-balanced — reject at score >= 75
• appsec-bot-challenge-scoring-permissive — reject at score >= 100

Usage

Most users should install a ready-made bundle (appsec-bot-challenge and its strict / permissive variants) which wire this engine to a threshold for you, rather than composing it by hand.
