Web Application and API Protection (WAAP)

Overview

Web Application and API Protection (WAAP) is a security capability or service category that protects web applications and APIs through controls such as traffic inspection, web application firewalling, API discovery, bot management, rate limiting, and denial-of-service mitigation. WAAP is a layered protection approach, not a substitute for secure design, authorization, testing, patching, or application monitoring. It should be interpreted alongside Cloud Access Security Broker (CASB), which may affect the same workflow without representing the same control, event, or risk.

Misconfiguration, encrypted or nonstandard traffic, unknown APIs, business-logic abuse, credential attacks, false positives, and provider outages can bypass or disrupt protection.

Organizations should inventory applications and APIs, define positive and negative rules, integrate identity context, tune bot and rate controls, test bypasses, monitor coverage, and plan failover.

Retain protected hosts and routes, policies, rule versions, exceptions, blocked and allowed events, false-positive reviews, latency, availability, tests, and incident outcomes.

A production treatment of Web Application and API Protection (WAAP) should test protection of web applications and APIs through controls such as traffic inspection, web application firewalling, API discovery, bot management, rate limiting, and denial-of-service mitigation within the relevant asset, decision, or service state. The Web Application and context record for web application firewalling, API discovery, and bot management should preserve source data, configuration or policy version, responsible actor, exception, and outcome. Review of Web Application and API Protection (WAAP) should determine whether safeguards addressing web application firewalling, API discovery, and bot management changed exposure in practice, not merely whether a document or setting existed.

Quality review for Web Application and API Protection (WAAP) should sample real cases involving web application firewalling, API discovery, and bot management, compare expected and actual outcomes, and track unresolved exceptions until remediation is independently verified.
