Understanding the need for security, the API security testing process is necessary for secure API development. If not addressed well, the future of API security will become more prone to vulnerabilities leading to cyber-attacks. The only conclusion we can draw from such API attacks is that the present situation could worsen in the coming years if not secured now.

Before we proceed, you might have questions like “How do we secure API development?” or “What are the comprehensive API pen testing strategies?” and more. This blog will cover every aspect of upcoming API security testing so you can better understand it. Let’s dive in.

What is API Security?

To understand API security testing, we must first understand its meaning. In simple terms, API security stands for application programming interface security. This practice prevents or mitigates attacks on APIs.

API security testing methods safeguard sensitive data when transferred. APIs are a backend framework for applications and mobiles. In other words, an API is an interface that defines a language of interaction between different software. They protect all data formats used in Internet of Things (IoT) applications and web pages.

Emerging Trends of API Security Testing

The dynamics of API security testing are evolving by the day. The future of API security will have trends that speed up the testing and simplify the whole process. Modern API pen testing trends help identify, prevent, and mitigate security risks in applications and web pages. We have created a detailed list of API security best practices for 2024. Let’s dive in:

Manual Penetration Testing

Be it a traditional method, it is still one of the top choices regarding API security. Manual penetration testing, or pen testing, is a process by a team of humans to attack and break a computer network to identify vulnerabilities. This method helps organizations improve the security of their networks and applications. Although time-consuming, manual penetration testing is the most effective method so far.

Where automated scans miss out on complex vulnerabilities, manual penetration testing simulates real-world attacks. This way, testers can identify vulnerabilities that automated tools often overlook. Further, human expertise plays a crucial aspect in manual penetration testing. With good experience in the industry, a professional can analyze and interpret more effectively.

Manual penetration testing creates real-world scenarios that test APIs’ resilience against security challenges. In addition, regular pen testing helps people be aware of evolving vulnerabilities and address them promptly. Once manual penetration testing is completed, testers provide meticulous reports that help mitigate and fix security issues.

Automated Scans

In simple terms, Automated scans, also known as automated penetration testing, identify vulnerabilities in systems, applications, and networks without human intervention. They perform continuous and systematic checks to identify potential vulnerabilities attackers could exploit. Automated API security scans have many benefits.

Automated scans or automated penetration testing provide continuous monitoring through surveillance. This ensures the identification of vulnerabilities and addresses security issues before any severe threat occurs. Further, automated scans provide regular and comprehensive coverage for all aspects of the API.

Automated scans are part of CI/CD security. This integration with the Continuous Integration/Continuous Deployment (CI/CD) pipeline helps organizations detect security flaws early. As a result, organizations can reduce the risk of exploitation before reaching the production stage. In addition, setting up real-time alerts for automated scans helps to provide immediate response when vulnerabilities are detected.

Secure Code Reviews

Secure code review is a simple yet systematic way of reviewing software source code to detect and fix security vulnerabilities. It is one of the best practices of the software development cycle and helps to improve the overall security and quality of the application.

Being an integral part, this approach helps identify security flaws in the early stages. This results in a secure API development with fewer breaches and attacks. A secure code review’s primary goal is to ensure that the software complies with the security standards. This primarily helps identify vulnerabilities and save time, money, and reputation. A secure code review also ensures that code is laid down most securely, reducing the risk of potential threats and attacks. Not only this, developers also use this tool to streamline the process by scanning the code for basic and common vulnerabilities.

In addition to automated tools, peer reviews help to understand different perspectives and add another layer of scrutiny. There might be something that one developer misses; peer reviews catch such issues and ensure a more secure codebase.

Software Composition Analysis (SCA)

Another trending API security testing tool is Software Composition Analysis (SCA). Simply put, it is an automated process that detects open-source software in a codebase. The primary goals of SCA are to evaluate security, license compliance, and code quality.

SCA is essential for spreading awareness about organizations’ open-source license limitations and obligations. Moreover, tracking such limitations manually can be arduous. SCA testing lets developers work efficiently without compromising quality in the modern DevOps or DevSecOps environment.

SCA has become crucial in detecting all open-source and third-party libraries. This way, developers will know what external code is required to be integrated into the application. Once such components are identified, SCA tools evaluate security and check known vulnerabilities. This way, no insecure components are added to the software, reducing the risk of exploitation.

SCA tools also continuously monitor the identified components for new updates or vulnerabilities. This helps developers be prompt in case of security breaches and attacks. Besides this, SCA also checks the licenses of identified components. It is important to find unapproved components, reducing legal and security risks. Additionally, SCA tools help in risk management by emphasizing vulnerabilities. This way, developers can address the most crucial ones beforehand.

API Hosting Environment Architecture Review

The next on the list is the API hosting environment architecture review, which is a comprehensive evaluation of the design principles, patterns, and guidelines through which developers host and manage APIs. The primary goal of this review is to ensure that the system is secure, efficient, and scalable.

The key components of API hosting environment architecture review include the following: 
Security Architecture Assessment: An API hosting environment architecture review helps developers evaluate the security framework. These assessments help identify and assess the existing security controls. Further, developers ensure the applications’ alignment with industry standards like OWASP and NIST.

Robust Security Measures: The primary goal of such measures is to ensure that strong measures are in place to protect the hosting infrastructure. Developers implement firewalls, IDS, and anti-malware tools for secure API development. Further, regular updates and patch software and TLS/SSL are necessary to encrypt data in transit.

Network Segmentation: This helps limit the impact of potential vulnerabilities in security breaches by breaking the network into isolated segments. To figure this out, developers implement Virtual local area networks (VLANs) for network separation. This also helps monitor traffic from unauthorized places and handle unauthorized activities.

Access Control: The component aims to protect data and resources by enforcing strict control policies. As a result, developers implement role-based access control to limit access and use multi-factor authentication to safeguard sensitive systems.

Regular Audits: Verifying compliance with proper security standards is one of the most important practices. This helps to conduct internal & external audits, analyzing audit logs for potential breaches. Developers also ensure compliance with necessary regulations like HIPAA and GDPR).


API Hosting Server Penetration Testing

This API security testing is a security assessment process through which the security of an API is evaluated by simulating the conditions of a real attack. The types include REST, SOAP, and GraphQL. During an API hosting server penetration testing, the developers aim to find the most critical vulnerabilities mentioned in security standards. Thus, the test covers:

Server Security: The primary goal is to find and fix vulnerabilities through penetration testing. Developers perform regular tests on servers hosting APIs and simulate real-world attack scenarios, which provides actionable recommendations to remediate discovered vulnerabilities.

Configuration Review: Developers check whether the configurations adhere to security best practices. Developers review and check configurations and misconfigurations for better results, such as open ports, weak passwords, and more.

Patch Management: Patch management helps to keep the servers updated with the latest security patches and updates. In this case, developers establish a schedule to ensure timely updates, maintain an inventory, and test patches in the staging environment.

Monitoring and Logging: This helps detect and promptly respond to security incidents. Developers implement logging mechanisms and use security information to capture relevant events.

Incident Response: A proper incident response system helps handle potential breaches effectively. Developers create a plan and define roles and responsibilities to ensure the team is ready for incidents.

API Microservice Container Security Testing

Another trending API security testing is API microservice container security testing. API microservice security simply means a set of practices, tools, and methods to safeguard microservices and interactions through APIs.

Developers secure microservices and containerized environments by implementing security best practices. This helps them regularly review and update security measures to address potential threats.

API microservice security also helps in image scanning through automated image scanning tools. Developers also validate the integrity and authenticity of container images. Further, it helps monitor and secure containers during operation runtime.

Developers also focus on limiting the exposure and potential damages by segmenting the container networks. They design and use virtual network policies to isolate container groups and monitor network traffic.

Another important aspect of API microservice security is orchestration security. This ensures secure configurations and operations of a container on orchestration platforms. Developers can conduct security tests, review configurations, and implement access controls to restrict information.

API Development and Deployment Process Review

The last on our list is API development and deployment process review. This API security testing refers to evaluating and assessing the lifecycle stages involving developing, testing, deploying, and maintaining APIs. Some of the key aspects of API development and deployment process review include the following:

Development lifecycle review: The primary goal of this aspect is to assess the practices used throughout the cycle to ensure secure API development. Developers mainly review the plan, design, code, and deployment phases.

CI/CD Integration: The objective behind this is to evaluate the process of security checks and validations. Developers examine every security testing tool at each stage to identify vulnerabilities early.

Secure DevOps Practices: This assesses the seamless adoption of DevSecOps principles into the system. Developers evaluate how security has been incorporated through security configurations, continuous monitoring, and incident response. Moreover, it is not the result but an integral part of the cycle.

Compliance and Standard Adherence: Developers ensure APIs adhere to industry security standards and regulatory requirements throughout their life cycle. As a result, they conduct audits, assessments, and documentation.
