An Application Programming Interface (API) is a set of protocols that allow software components to interact. The intermediary interface is commonly used for streamlining development by enabling software teams to reuse code. APIs also abstract functionality between systems by decoupling applications from the infrastructure they run on. Though APIs’ benefits and use cases in modern business continue to rise, inherent security challenges present various security risks.

This article delves into various risks associated with API vulnerabilities while learning common API security best practices to implement robust security mechanisms.

An API represents a set of services that allow one program to communicate with another external or internal program. When we talk about API security, we typically refer to securing an application’s backend services, including its database, user management system, or other components interacting with the data store.

API security encompasses the adoption of multiple tools and practices to protect the integrity of a tech stack. A robustly secured API covers both the APIs an organization uses and the services that use them. This includes preventing malicious actors from accessing sensitive information or taking actions on your behalf that you did not intend them to perform. Unfortunately, while APIs are a crucial part of modern applications, they are a common target of attackers to access sensitive information.

It is crucial to understand how third-party applications funnel data through the interface when using APIs. Furthermore, with APIs increasingly becoming an attack vector, API security measures help security teams to assess security risks and have a comprehensive plan to protect them.

Risks of API Vulnerabilities

As APIs are publicly accessible, they are common targets to steal sensitive information, including application logic, user credentials, credit card numbers, etc. In addition, vulnerabilities in an API endpoint are also exploited by malicious actors to gain unauthorized access to a system or network
