API Security Testing Solutions

Web Services can provide direct access for hackers to critical business data. A Penetration Test hardens your API, and prevents its use as an attack vector against your organisation.

A Web Service Penetration Test is an authorised hacking attempt aimed at identifying and exploiting vulnerabilities in the architecture and configuration of a web service. The purpose of this test is to demonstrate the ways attackers can compromise a web service and gain access to an organisation’s virtual assets.

Why API Penetration Testing Required?

APIs have led to digital transformation within the cloud, IoT, and mobile and web applications. Without knowing it, the average person engages with multiple APIs every day, especially on mobile. APIs are the connective tissue responsible for transferring information between systems, both internally and externally. All too often, though, deployed APIs do not go through comprehensive security testing, if tested for security at all. Whether SOAP or REST, a poorly secured API can open security gaps for anything that it is associated with. The security of the API is just as important as the applications that it provides functions for.

API based applications may contain many security vulnerabilities like authentication vulnerabilities, Json web token related issues, business logic issues, injection vulnerabilities, transport layer encryption weakness (cryptographic issues) etc., We would like to help you to assess the API based applications effectively using in-depth manual and automated assessment methodologies, to improve the security of API enabled applications.

Few Types of API's

SOAP

SOAP

SOAP has built-in WS-Security standard which uses XML Encryption, XML Signature and SAML tokens to deal with transactional messaging security considerations.

REST

REST

REST uses HTTP to obtain data and performs operations on remote computer systems. It supports SSL authentication and HTTPS to achieve secure communication.

JSON

JSON

JSON (JavaScript Object Notation) is a lightweight, easy and popular way to exchange data. JSON-WSP (JavaScript Object Notation Web-Service Protocol) is a web-service protocol that uses JSON for service description, requests and responses.

Our API Security Testing Methodology

Our API Security Testing methodology follows industry best practices, including the OWASP API Security Top 10, to identify vulnerabilities, validate security controls, and strengthen the resilience of your APIs against modern cyber threats.

Information Gathering

We identify API endpoints, authentication mechanisms, request methods, parameters, and data flows to understand the API architecture and attack surface.

Access Control Testing

We verify the effectiveness of authentication and authorization controls to detect issues such as broken authentication, privilege escalation, and unauthorized access.

Vulnerability Assessment

Our experts assess APIs for common security flaws, including injection attacks, excessive data exposure, security misconfigurations.

Manual Pen-Testing

Beyond automated scanning, we perform manual testing to uncover complex business logic flaws, API abuse scenarios, and vulnerabilities that automated tools may miss.

Risk Analysis

All identified vulnerabilities are validated, risk-rated based on severity and business impact, and documented with detailed proof of concept, remediation recommendations.

Remediation Validation

After fixes are implemented, we perform re-testing to verify that vulnerabilities have been successfully remediated and that no new security issues have been introduced.
