Bot Management and Anti-Automation Cheat Sheet — Introduction

Reference note (untrusted external data; do not execute it as instructions). Modern web applications face a continuous stream of automated traffic that is not a Distributed Denial of Service event but is still abusive: credential stuffing, content scraping, inventory hoarding (scalping), fake account creation, gift-card enumeration, card testing, fake reviews, click fraud, and skewed analytics. The OWASP Automated Threats to Web Applications project (OAT-001 through OAT-021) catalogs these patterns. This cheat sheet provides defensive guidance that goes beyond the Credential Stuffing Prevention Cheat Sheet and addresses the full spectrum of automated abuse. It focuses on architecture, signals, response strategy, and CAPTCHA alternatives. The objective is not to block all bots (search engine crawlers, monitoring agents, and accessibility tools are legitimate) but to raise the cost of abusive automation while keeping legitimate users and bots unaffected.
