Implementing API Threat Protection with Apigee

Overview

Google Apigee is an enterprise API management platform that provides native security policies for threat protection, including JSON and XML content validation, OAuth 2.0 enforcement, SpikeArrest rate limiting, regular expression threat protection, and Advanced API Security for detecting malicious clients and API abuse patterns. Apigee operates as a reverse proxy that intercepts all API traffic, applying security policies before requests reach backend services, effectively shielding APIs against the OWASP API Security Top 10 threats.

When to Use

• When deploying or configuring implementing api threat protection with apigee capabilities in your environment
• When establishing security controls aligned to compliance requirements
• When building or improving security architecture for this domain
• When conducting security assessments that require this implementation

Prerequisites

• Google Cloud Platform account with Apigee organization provisioned
• Apigee X or Apigee hybrid environment configured
• Backend API services deployed and accessible from Apigee
• Google Cloud CLI (gcloud) installed and authenticated
• OpenAPI specification for target APIs
• Understanding of Apigee proxy bundle structure

Core Security Policies

1. JSON Threat Protection

Protects against JSON-based denial-of-service attacks by limiting structural depth, entry counts, and string lengths:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<JSONThreatProtection name="JSON-Threat-Protection-1">
    <DisplayName>JSON Threat Protection</DisplayName>
    <Source>request</Source>
    <!-- Maximum nesting depth of JSON structure -->
    <ObjectEntryNameLength>50</ObjectEntryNameLength>
    <ObjectEntryCount>25
    100
    5
    500
