Netsparker can scan web applications that use Application Programming Interfaces (API).
- When most people think of web security, they think about testing websites and web applications. Over 80% of web traffic, however, is actually sent through web APIs.
- In parallel to this traffic, malicious attackers have begun to target APIs. According to Salt Security's report, for example, its customers experienced an average of 12.22 million attack calls per month by June 2021.
- These attacks are also expected to increase. Gartner’s report How to Build an Effective API Security Strategy predicted that APIs would become the number one attack vector in 2022.
Challenges to scan APIs
Despite these warnings and the increasing trend to attack APIs, it remains, however, a challenge to secure them because of the following reasons:
- There isn’t a clear standard to secure APIs in order to avoid vulnerabilities. To secure APIs, their unique logic needs to be understood.
- APIs and web applications use the same language and technologies. This means APIs are also prone to the same types of security risks and attacks, for example, SQL injection attacks. However, as APIs are discrete endpoints and if the scanners do not know how to find these endpoints, the scanners cannot test the API security.
- Also, the fast pace of development means the constant evolution of APIs. So, this pace turns API security into a challenge.
As an advanced black-box security tool, Netsparker can scan websites, web applications, and web services, and identify security flaws. It can scan all types of web applications, regardless of the platform or the language with which they are built. So, Netsparker can identify vulnerabilities in your APIs and offer remedies to fix them.
Scanning APIs with Netsparker
You can use Netsparker to identify vulnerabilities related to SOAP, REST, and GraphQL API. Each topic is explained in their respective topics:
- Scanning a RESTful API Web Service
- Scanning a GraphQL API for vulnerabilities
- Scanning SOAP API Web Services
Using Postman or Fiddler? Netsparker supports such tools to import your links for security testing. For further information, see Importing Links and API Definitions and Importing links from supported tools.
