Are you ready for an action-packed adventure that involves APIs and cyber-security? Well, fasten your seat belts and hold on tight as we take you through the world of broken function-level authorization (BFLA) in APIs.

Use Case 1: The Matrix

In a large e-commerce company, there was an API that allowed admins to manage products and prices. However, the function-level authorization was broken, and non-privileged users were able to access the admin API and change product prices to zero. This led to a catastrophic loss of revenue for the company. But our hero wasn't going to let the hackers win. Armed with his knowledge of API security, he was able to fix the authorization issue and restore the prices to their rightful value.

Use Case 2: James Bond

A banking company had an API that allowed users to transfer money between accounts, but the function-level authorization was broken. Non-privileged users were able to access the API and transfer money from other accounts without authorization. Our hero knew that the hackers were using a different verb in the API call to gain access. So, he used his API defense tactics to change the verb and fix the broken authorization. In the end, he was able to save the bank from a major cyber-attack.

Use Case 3: The Italian Job

In a transportation company, there was an API that allowed admins to manage shipments and routes. However, the function-level authorization was broken, and non-privileged users were able to access the admin API and change the routes. This led to a series of missed deliveries and lost cargo. But our hero wasn't going to let the hackers get away with it. Using his knowledge of API security, he was able to fix the broken authorization and prevent any further unauthorized access to the API.

These use cases demonstrate the importance of proper function-level authorization in API security. It's not just about keeping administrative functions hidden from non-privileged users, but also about ensuring that authorized users only have access to the functions they are supposed to have access to. By being vigilant and proactive in addressing BFLA, we can prevent our APIs from becoming action movie villains.

So, are you ready to become an API security hero like our protagonist? With the right knowledge and techniques, you too can save the day and protect your APIs from cyber-attacks and grab a Pynt to ensure no BFLA is there.
