With the rise of microservices and cloud-based applications, [APIs](https://en.wikipedia.org/wiki/API) have become a critical component of modern software development. APIs allow developers to build complex applications by integrating various services and components. 

In a [DevSecOps](https://www.redhat.com/en/topics/devops/what-is-devsecops) environment, [API Gateway](https://apisix.apache.org/docs/apisix/terminology/api-gateway/) is a critical component that helps to achieve the core principles of DevSecOps, which are collaboration, automation, and security. In this article, we will walk you through the **6 reasons why API Gateway is important** in building APIs with **DevSecOps** approach. 

## Learning objectives

You will learn the following throughout the article:

- What is DevSecOps?
- Major steps and tools in implementing DevSecOps.
- The role of API Gateway in DevSecOps.

## What is DevSecOps?

> [DevSecOps](https://www.dynatrace.com/news/blog/what-is-devsecops/) (Development, Security, and Operations) is an approach to software development that emphasizes integrating security practices into the entire software development life cycle.

Traditionally, security has been treated as an afterthought in software development, with security testing and assessment occurring only at the end of the development cycle. DevSecOps, however, seeks to embed security considerations into every step of the development process, from API design and development to testing, deployment, and maintenance.

By doing so, DevSecOps aims to create a culture of security and responsibility within development teams and organizations. This approach ensures that security concerns are addressed from the outset and that the resulting software is more secure, less susceptible to attack while meeting the velocity of today’s rapid release cycle. You can read more about **the benefits of leveraging DevSecOps** approach in [this article](https://www.vmware.com/topics/glossary/content/devsecops.html).

## Steps and tools for successful DevSecOps practices

Implementing DevSecOps involves a set of practices, principles and tools. Here are the common steps and popular tools used to achieve:

1. **Include security in your requirements**: From the start of your project, ensure that API security requirements are clearly defined and integrated into the overall project plan.

2. **Use Infrastructure as Code (IaC)**: Use tools such as [Terraform](https://www.terraform.io/), [Ansible](https://www.ansible.com/), or [CloudFormation](https://aws.amazon.com/cloudformation/) to provision and manage your infrastructure. By using IaC, you can ensure that your API infrastructure is secure from the start and that security policies are enforced consistently.

3. **Use a container orchestration platform**: Use a container orchestration platform such as [Kubernetes](https://kubernetes.io/) to manage your infrastructure. Kubernetes provides a range of security features that can be used to secure your applications, infrastructure and manage the traffic to your containerized environment securely using [Ingress Controller](https://apisix.apache.org/blog/2022/09/09/kubernetes-ingress-with-apisix/). 

4. **Secure your API**: Use an  to [secure API Gateway](https://apisix.apache.org/) by adding authentication, rate limiting, and other security features. It reduces the number of exposed APIs, organizations can reduce surfaces of attacks.

5. **Automate security testing:** Use tools such as [OWASP ZAP](https://owasp.org/www-project-zap/), [SonarQube](https://www.sonarsource.com/products/sonarqube/), or [Checkmarx](https://checkmarx.com/) to automate security testing. This will help you identify security issues early in the development process and reduce the risk of vulnerabilities being introduced into your code.

6. **Monitor your infrastructure and APIs:** Use tools such as [Prometheus](https://prometheus.io/), [Grafana](https://grafana.com/), or [ElasticSearch](https://www.elastic.co/) to monitor your infrastructure and APIs. This will help you detect and respond to security incidents in real-time.

## The role of API Gateway in DevSecOps

**API Gateway** provides a unified entry point for all API requests and is responsible for managing the entire API lifecycle from creation to deployment and monitoring. [This post](https://www.iambobur.com/post/how-to-choose-the-right-api-gateway) guides you on **how to choose the best API Gateway** solution for your applications.

Here are _6 common reasons why API Gateway_ is essential in achieving DevSecOps:
 
### Number 1: Security and Compliance

A modern API Gateway provides various **security features** such as Authentication([API key](https://apisix.apache.org/docs/apisix/plugins/key-auth), [Basic Auth](https://apisix.apache.org/docs/apisix/plugins/basic-auth/), [OAuth2)](https://apisix.apache.org/docs/apisix/plugins/openid-connect/), authorization, [rate-limiting](https://apisix.apache.org/plugins/#Security), encryption and data masking, which help to secure API requests and responses.

API Gateway can also help to mitigate various security threats such as [DDoS attacks](v), [SQL injections](https://en.wikipedia.org/wiki/SQL_injection), and [cross-site scripting](https://en.wikipedia.org/wiki/Cross-site_scripting) (XSS) attacks by enforcing security policies and controls. Learn more about [securing APIs in the API Gateway](https://api7.ai/blog/secure-api-in-api-gateway).

API Gateway can [prevent the sensitive data from leaking](https://api7.ai/blog/apisix-prevents-sensitive-data-leaking) and help to ensure compliance with various regulatory requirements such as [PCI-DSS](https://en.wikipedia.org/wiki/Payment_Card_Industry_Data_Security_Standard), [HIPAA](https://en.wikipedia.org/wiki/Health_Insurance_Portability_and_Accountability_Act), and [GDPR](https://en.wikipedia.org/wiki/General_Data_Protection_Regulation) by enforcing data privacy and protection policies. API Gateway can also help to monitor and audit API requests and responses to ensure compliance with various security and privacy standards.

### Number 2: Monitoring

API Gateway allows you to [monitor the usage](https://dev.to/apisix/apis-observability-with-apache-apisix-plugins-1bnm) and performance of your APIs, which can help you identify and address any issues before they become critical. This can also help you to identify potential security threats, and mitigate them before they cause any damage.

With the API Gateway, you can [transform your logs](https://api7.ai/blog/apisix-transforms-logs-for-observability) to enhance observability and integrate with tools such as [Prometheus](https://prometheus.io/), [Grafana](https://grafana.com/), or [ElasticSearch](https://www.elastic.co/).

### Number 3: Scalability

API Gateway can help to improve the scalability of API-driven applications by providing various features such as **caching, load balancing, and auto-scaling**. API Gateway can also help to optimize API performance by routing requests to the appropriate backend services based on their availability and response time.

### Number 4: Management

API Gateway provides a unified interface for managing APIs, which helps to streamline development and [deployment processes](https://api7.ai/blog/api-release-strategies-with-api-gateway). API Gateway can also provide various management features such as **versioning, documentation, and testing**, which help to ensure the quality and reduce the risk of errors and downtime, ensuring that your APIs are always available when you need them.

### Number 5: Integration

API Gateway makes it easier to **integrate your APIs with other systems**, including cloud-based services and third-party applications. This can help you to streamline your operations and improve your overall efficiency.

### Number 6: Collaboration

API Gateway can help to improve collaboration between development, operations, and security teams by providing a shared platform for managing APIs. API Gateway can also provide various collaboration features such as **role-based access control, notifications, and alerts**, which help to ensure timely and effective communication between teams.

## Conclusion

In conclusion, API Gateway in DevSecOps environment provides critical security, compliance, scalability, management, and collaboration features that help to ensure the safe and secure delivery of APIs. API Gateway can help to improve the overall quality and reliability of API-driven applications, allowing developers to focus on creating new features and improving the user experience.
