The positive security model (whitelist) rejects everything that is not identified as allowed while the negative security model (blacklist) operates on the basis of the banned items and allows everything. Security Web Application Firewall prevents many attacks like Cross-site Scripting (XSS), SQL injection, Cookie poisoning, Unvalidated Input, Layer 7 DoS, and Web scraping — data scraping.
