Application Programming Interfaces, commonly referred to as APIs, are one of the most commonly used technologies in mobile applications.<\/p>\n

While there are several APIs used to add a security layer to existing applications, API security is something that a lot of stakeholders underestimate.<\/p>\n

The term API Security refers to the process of securing APIs against cyberattacks. Well, an API is the bridge that allows two software programs to communicate with each other. And exchanging crucial information, they are the point hackers attack first.<\/p>\n

Hence, paying attention to API security is a must. If you are someone who works with APIs regularly, or are planning to integrate an API into your application, make sure you read this post till the end, as API security is not as simple as your app security.<\/p>\n

Wondering how? Well, let\u2019s start by addressing the core differences between app security<\/a> and API security.<\/p>\n

<\/span>App Security Vs API Security: Addressing the Basics<\/span><\/h2>\n

A mobile app is generally built with a combination of custom-implemented functionalities and APIs.<\/p>\n

An API is a bridge between two platforms, giving functionalities or data from one to another without having to build it completely from the ground up.<\/p>\n

While the focus of security in mobile apps<\/a> is on the user\u2019s flexibility and data security, APIs work on keeping the business secure by maintaining secure parameters around the APIs that are being used in the application.<\/p>\n

To give you a clearer picture of the solution, below is a table that might help you understand the difference between App Security and API Security.<\/p>\n\n\n\n\n\n\n\n\n\n

The table gives you a clear understanding of the differences between API and App security. While this means you must pay attention to both, it also means that API security is a threat that has the potential to put all your app’s data at risk.<\/p>\n

Which brings us to discussing the core importance of API security. Check out the next section, where we focus on API security and why it is important to pay attention to keeping them secure.<\/p>\n

<\/span>Key Components of API Security: What Makes it Important?<\/span><\/h2>\n

APIs are responsible for transferring important data. For instance, the Open Banking API<\/a> allows fintech apps like eWallet to access a person\u2019s bank data.<\/p>\n

So, in case anyone manages to hack, expose, or compromise the API, it can mean a leak of personal data, financial data, and any other data of a sensitive nature.<\/p>\n

This is something that neither a business nor a user wants. And it can end up in a loss of billions, as we see every year.<\/p>\n

Therefore, securing the API is of immense importance.<\/p>\n

With software and app development growing in popularity, the use of API is also becoming very common. In addition to this, the number of cyber attacks is also increasing.<\/p>\n

For that reason, securing APIs is more important than ever. Two core components of API security can help you understand how API security works and where exactly the measures should be implemented.<\/p>\n

<\/span>API Security Management<\/span><\/h3>\n

A big part of keeping your API secure is implementing API Security Management. To achieve this, there are 3 core security schemes that can be implemented.<\/p>\n

These are, as mentioned below:<\/p>\n
