As data-driven enterprises rely heavily on their software application architecture, application programming interfaces (APIs) occupy a significant position. APIs have revolutionized the way web applications are used, as they aid communication pipelines between multiple services. Developers can integrate any modern technology with their architecture by using APIs, which is highly useful for adding features that a customer needs.   

By nature, APIs are vulnerable to exposing application logic and sensitive data such as personally identifiable information (PII), which makes them an easy target for attackers. Often available over public networks (accessible from anywhere), APIs are typically well-documented and can be quickly reverse-engineered by malicious actors. They are also susceptible to denial of service (DDoS) incidents. 

The most significant data leaks are due to faulty, vulnerable or hacked APIs, which can reveal medical, financial and personal data to the general public. In addition, various attacks can occur if an API is not secured correctly, making API security a vital aspect for data-driven businesses today.

Why API security is essential

API development has astronomically increased over the past few years, fueled by digital transformation and its central role in mobile apps and IoT development. Such growth and a variety of possible attacks make API securit...
