Threat Protection

As an API management platform, Apigee provides policies that can be used to detect and reject XML and JSON threats. The aim of the threat-protect API proxy is to help you configure XML and JSON threat protection policies. The threat-protect API proxy can dynamically generate XML and JSON threats that are both used as a source to respectively test XML and JSON threat protection policies.

Dependencies

Quick start

Apigee X / hybrid

export APIGEE_X_ORG=xxx
export APIGEE_X_ENV=xxx
export APIGEE_X_HOSTNAME=api.example.com

./pipeline.sh --googleapi

Apigee Edge

export APIGEE_ORG=xxx
export APIGEE_ENV=xxx
export APIGEE_USER=xxx
export APIGEE_PASS=xxx

./pipeline.sh --apigeeapi

Script outputs

The pipeline script deploys on Apigee (Edge, hybrid or X) an API Proxy containing the full configuration of the threat protection reference.

What are we testing?

The threat protection reference allows you to test structural limits of XML and JSON contents. More specifically, structural dimensions are defined by:

  • width
  • height
  • depth
  • length

As said before, XML and JSON threats are created by the API proxy. Following paragraphs present dimensions for the 2 types of contents, for which we want to test limits using either an XML or JSON threat protection policy.

Structural dimensions of an XML document

Here is a picture describing the structural dimensions of an XML document:

XML threat

  • width refers to the number of attributes on elements/tags
  • depth refers to the node depth of an XML document
  • height refers to the number of child elements of the root element
  • length refers to the number of namespaces of the root element

Structural dimensions of a JSON content

Here is a picture describing the structural dimensions of a JSON content:

JSON threat

  • width refers to the number of entries in an object
  • depth refers the containment depth, where the containers are objects in this case
  • height refers as well the number of entries on the JSONThreat object (root)
  • length refers to the number of items in the items array

API proxy Endpoints

Available endpoints are the following ones:

  1. GET /xml: to generate an XML threat and test the XMLThreatProtection policy
  2. GET /json: to generate a JSON threat and test the JSONThreatProtection policy

Once the threat-protect API Proxy has been installed on a target organization and deployed into an environment, here are values for these different endpoints and method available for each of them:

Endpoint Available method + URI
XML threat test GET /threats/v1/xml
JSON threat test GET /threats/v1/json

Endpoints details

Here is a detailed description of each endpoints and in particular the list of required parameters for each of them:

XML

HTTP Method Base Path Endpoint URI
GET /threats/v1 /xml

JSON

HTTP Method Base Path Endpoint URI
GET /threats/v1 /json

List of parameters

Name Type (query/header/form) Value Required (yes/no)
width query integer no
height query integer no
length query integer no
depth query integer (min. depth = 3)* no

(*): due to the structure of XML and JSON contents generated.

Example for JSON threat protection

Method:
GET
URI:
/threats/v1/json?width=10&length=20&depth=30&height=17

Output:

Either a fault (status code:400 - message:"Bad Request") or the JSON content (status code:200) that is generated by the proxy. You can modify the configuration of the JSON threat protection policy to configure this security policy as desired.

Example for XML threat protection

Method:
GET
URI:
/threats/v1/xml?width=10&length=20&depth=30&height=17

Output:

Either a fault (status code:400 - message:"Bad Request") or the XML content (status code:200) that is generated by the proxy. You can modify the configuration of the XML threat protection policy to configure this security policy as desired.
