Ensuring Web Services and API security in your organizations

APIs or Application Programming Interface and Web Services are the ways employed by the applications to exchange data. These are an integral part of software development as they connect and transfer data and logic over multiple systems and applications.

Web Service Testing is testing used for validating web services for functionality, reliability, performance and security of an API (Application Program Interface).

The web services and the APIs available in the public domain have to be tested rigorously, ensuring there are no loopholes, which may be exploited by the threat actors to harm the software or its users.

How do we do Web Services and API Security?


Adopting a hybrid approach for implementing the security, for Penetration testing wherein we follow the OWASP methodology and have included our specially designed test cases. We ensure an all-around approach for the testing. After the testing all the findings are documented, we extend our support to the developers and help them build secure coding practices ensuring API security issues from arising again. 


1. Project Planning - Planning the flow of the project thoroughly for the proper implementation of the Web services and API testing to be processed seamlessly.  


2. Customised Test Cases - Specifically designed test cases designed for the proper testing of the applications.


3. Automation Testing - Testing the application using the automation tools to ensure the testing is done from the industry-rated tools.


4. Manual Testing - Ensuring foolproof assessments by testing manually for the codes that may be surpassed by automation. 


5. Reporting - Preparing the complete report by documenting everything for future reference.      



Web Services and API testing has to be tested rigorously based on the protocols defined to ensure the safety of the user and network. The application based on APIs and Web services should be safe against hacking attempts. How safe are your applications?

API testing can be done in both ways depending on the requirements. Automation is generally recommended for larger projects that require comprehensive and frequent testing. Manual testing can be helpful when dealing with smaller projects or individual features.
An application may fail due to API failure. Any information that the API shares with a third-party app is sent back to the internet in the end. So, APIs can reveal private and sensitive financial, medical, and personal information, potentially harming a company's finances and reputation.
The time required for API security testing depends on the scope and infrastructure of the project. Depending on the number of test cases, the time taken may vary from a few hours to a few days.
Depending on the size and complexity of an API security test, the price might range from $350 to $3,000 per scan.
Yes, you will get 2-3 rescans depending on the service agreement.
Web Services and APIs across various domains can be assessed, including RESTful APIs, SOAP (Simple Object Access Protocol) web services, GraphQL APIs, microservices APIs, third-party APIs, and cloud-based APIs.
While traditional application security testing focuses on testing web applications from a user interface perspective, Web Services and API Assessment specifically evaluate the security and functionality of APIs at the interface level. It involves techniques such as fuzz testing, input validation, and access control testing.
Common tools include API vulnerability scanners like OWASP API Security Top 10, Burp Suite, Postman, SoapUI, and custom scripting for API testing. Techniques may include parameter tampering, authentication testing, authorization testing, and session management testing.
Common security risks include injection attacks (such as SQL injection and XML injection), broken authentication, insecure direct object references, lack of input validation, excessive data exposure, and inadequate access controls.
Web Services and API Assessment help organizations identify and remediate security vulnerabilities that could lead to non-compliance with regulatory requirements. By ensuring the security of APIs, organizations can protect sensitive data and meet the security controls specified by regulatory standards.
The frequency of Web Services and API Assessments depends on factors such as the complexity of the API landscape, changes in the API infrastructure, regulatory requirements, and risk tolerance. It is recommended to conduct testing regularly, ideally as part of the software development lifecycle and after major changes or updates to APIs.
Benefits include improved security posture, reduced risk of security breaches and data exposure, compliance with regulatory requirements, enhanced customer trust and confidence in API-based services, and cost savings through proactive risk mitigation.
Yes, Web Services and API Assessment services can be integrated with other security testing activities such as network penetration testing, web application testing, and mobile application testing. This provides a holistic approach to assessing an organization's overall security posture.
Yes, Web Services and API Assessment services can be tailored to address the unique needs, challenges, and objectives of organizations. Service providers can collaborate with clients to define scope, objectives, testing methodologies, and reporting formats based on specific requirements.
