API Security Scanning

APIs require different security approaches, different techniques, and different security knowledge than traditional web applications. Ensuring that APIs are suitably secured and covered with robust, API-specific vulnerability scanning should be a key priority for any organisation that operates a modern web presence. AppCheck has been developed by expert penetration testers to assess APIs intelligently in the same context-aware manner as a penetration tester would and using the same methodologies.

Benefits of AppCheck

Contextual probing of individual API methods

Performs function and method-specific API scanning that uses adaptive and heuristic fuzzing techniques to intelligently probe for weaknesses in API handling of parameters, headers, data types, structures, and formats.

Support for REST, SOAP & GraphQL APIs

Sophisticated and versatile scan logic that natively understands diverse API variants including REST (JSON), XML (SOAP) and GraphQL based APIs.

API Schema & Introspection support

Intelligent schema discovery and parsing support for API definition/specification formats including WSDL (XML), Swagger/OpenAPI (JSON, YAML) and GraphQL Introspection queries.

Customisable API authentication

Ability to authenticate against private APIs using multiple security definitions and authentication methods including API access keys.

Simulates manual penetration testing

Leverages proprietary technology developed in-house by penetration testers to perform API-specific vulnerability scanning, not simply applying legacy scanning techniques that fail to address API-specific security issues.

Full OWASP Top10 Coverage

Supports testing of all key OWASP Top 10 API Security Threats, including Broken Object level Authorization/IDOR, Broken Function Level Authorization, and commonly seen Injection vulnerabilities.

How does API Scanning work?

Web API scanners such as AppCheck work by checking your APIs for common pitfalls and security issues that could be prone to attack. Rather than use a database of static signatures of known weaknesses, the AppCheck platform applies a rigorous test methodology to tease out even previously unknown weaknesses in the same way a hacker or penetration tester would.

AppCheck does this by using schema definitions and other gathered intelligence to build an internal reference model of the API that can then be used to leverage advanced heuristic testing techniques. This methodology of building up custom and specific test cases for each API from “first principles” reveals security issues within your API that scanners using static or legacy testing techniques simply cannot uncover. AppCheck provides suggestions for how any discovered vulnerabilities can be solved, based on best practice guidance from organisations including OWASP and MITRE, as well as in-house experts.
