I’m going to cover basics of the API penetration testing. 3. The most popular clients are Postman or Insomnia. API Penetration Testing is one of the favourite attack surfaces, where the attacker can use to gain into further access to the application or server. This becomes extremely difficult when building permissive RESTful APIs that enable users to submit their own content (e.g in a chat application). Dynamically discover all mobile-connected APIs to identify unknown shadow APIs and test for risk using the OWASP API Top 10. Fortunately, there are resources to guide your thinking that don’t involve much more than reading the trade press. Most people don’t have the time or expertise to think of all the ways that people will intrude their application boundaries. API Security Top 10 2019.
