What Is API Security and How Does It Work? | TechBuzz

While the internet is essential and comes in handy in almost anything you do, there is still the issue of cyber threats.

Cyber threats, including data breaches, payment hacks, and high-security risks, have become a source of significant concern for businesses and individuals.

To protect your data, you must put cybersecurity measures in place. You’ll need to protect your apps and software, and one of the ways you can do that is through API security.

Read along as we discuss how API security works and its benefits.

What Is API Security?

An Application Programming Interface (API) is a software intermediary that allows your applications to communicate with one another.

Whenever you use a social networking app, gaming app, or any other app to send or receive messages, your actions pass through an API that connects you and the sender or receiver.

APIs are built with REpresentational State Transfer (REST) or Simple Object Access Protocol (SOAP). REST is famous for its simple techniques, and it has a simple architectural style for building web services. SOAP, on the other hand, is a message protocol that allows seamless communication between the elements of an application.

REST APIs function with transport layer security and HTTP and can also use Javascript Object Notation (JSON), while SOAP functions primarily with Hypertext Transfer Protocol (HTTP).

The message you send across may be sensitive, and with the onslaught of cybercrime, cybercriminals can extract this data to use in their illegal activities. Cyberattacks are constantly increasing, primarily through compromised identities and APIs. Examples of attacks that can affect APIs include identity attacks, parameter attacks, and man-in-the-middle attacks.

Following these cyberattacks, many web service providers require that security measures be improved by using several authentication methods that verify your identity. Ensuring that an API is secure enough for you to send any message across is the primary function of API security.

In the next section, you will discover how API security works.

How Does API Security Work?

APIs are essential to web-based interactions and thus, have become a target for cybercriminals and hackers. Because of this, basic identification methods like passwords and usernames are being replaced with security tokens and multi-factor authentication. This is how API security works.

API security functions primarily with the help of authorization and authentication.

Authentication is the first process involved in API security, and it verifies that your application process has a safe identity that allows you to use an API. On the other hand, authorization is the next step that determines the type of data an authenticated application has access to while communicating with an API.

In addition to having secure authentication and authorization, APIs are developed with more features that protect them and reduce their vulnerability to foreign attacks. Some of these features are as follows.

1. Security Tokens

A security token is an alternative to traditional passwords. It provides you with two-factor authentication to identify your login details. Your tokens have to be verified before you can use any service or resource assigned to any API.

2. Encryption and Signatures

Implementing data encryption and signatures using Transport Layer Security is one way to make an API secure. Transport Layer Security keeps your internet connection private and secures the data sent between you and a server. With this, one cannot extract your data from a website without a signature that identifies the right users.

3. Quotas and Throttling

Quotas are placed on your APIs to track their use and history and check if anyone abuses them. Throttling is an effective API security method that limits people’s access to your data. With throttling, you can notice irregularities in your API usage and create another layer of security to protect your data.

4. API Gateway

An API gateway serves as a muster point for all your API traffic. A secure API gateway will authorize and authenticate your traffic and control how you use your APIs.

These features identify vulnerabilities coming from your API by monitoring your network, API components, drivers, and operating system. They highlight the weak points of your API and detect areas where data breaches and security issues are most likely to attack.

Benefits of API Security

API security is vital because it protects your web service and application software from foreign attacks like cross-site scripting, sensitive data breach, and cyber theft. API security also enhances the performance and safety of APIs and any program they support.

The following are more benefits of API security.

1. APIs Do Not Depend on Technology


API security does not entirely depend on technology because it uses JSON languages and HTTP requests. This means that software developers can use any language to automate API services for any application.

2. API Security Gets Rid of Vulnerabilities

You need to take extra care when developing and testing APIs for vulnerabilities. This protects the application from foreign attacks and data breaches and adds an extra layer of security to limit its exposure to malware.

3. Faster Results

API security provides faster results whenever an application is tested. This is impressive because API requires less time, fewer codes, and lower costing. Likewise, the cost of running an API security check is less because these APIs detect malware early and save your applications from severe damage.

4. Errors Can Be Detected Without Your Notice


One of the benefits of API security is that your application does not have to undergo any damaging attacks from unknown codes because it can be accessed automatically without your notice. Your API security identifies and handles errors and viruses that plague your software at an early stage.

APIs offer developers an opportunity to modify the security of their applications by allowing them to leverage other applications. When a firm develops an application, they no longer have to go through reinventing to access things like authentication and authorization.

These firms and developers can leverage APIs that allow several applications to communicate with each other. Lastly, APIs make it easy for you to access applications and internet services and secure all your communication over the internet.

Create a Stronger Cybersecurity Framework With APIs

As long as you use internet-supported applications to run your day-to-day activities or communicate with business partners and friends, you make use of APIs. Hence, you need to monitor, test and manage all your APIs to ensure that your data and application software are secure.

Protecting your data would be difficult for you if you do not know what APIs are. Create a more robust cybersecurity framework by getting a handle on APIs and how best to leverage them.
