While a blacklist allows all requests except those matched by its patterns, awhitelist will not allow all request .they allow only those request which are defined in its ruleset. Features of Web Application Firewall : Validate inputs, thereby stopping dangerous SQL injection, cross-site scripting and directory traversal attacks . Detect cookie, session or parameter tampering attacks.. Block attacks that exploit vulnerabilities in custom web properties. . Credit Card and Social Security Number (SSN) masking.
