Burp Suite DAST (Dynamic Application Security Testing) finds security vulnerabilities in web applications. It simulates attacks on the application to identify weak spots that actual attackers could exploit.

In this blog, you will learn about the Burp Suite for DAST, is the Burp Suite SAST or DAST?, how the Burp Suite operates, the key features of Burp Suite DAST, its dashboard, functionalities, and alternatives to Burp Suite DAST.

Let’s get started

Overview of Burp Suite DAST

Burp Suite DAST, which forms an integral part of the comprehensive suite of tools provided by Burp Suite, stands as a notable solution in the field of dynamic application security testing (DAST). This tool was specifically designed to identify and address vulnerabilities present in web applications.

This tool effectively evaluates the security posture of applications by dynamically analyzing their behavior during runtime. Its robust features and capabilities make it a preferred choice for security professionals across the globe.

Burp Suite has several parts, each designed for different aspects of web application safety testing:

• Spider: Looks through websites to understand the application's structure.

• Scanner: Uses automatic scans to find security risks based on the application's behavior.

• Repeater: Sends custom requests to test specific functions.

• Sequencer: Checks how easy it is to guess things like session IDs.

• Intruder: Launches brute-force attacks against web applications.

• Decoder: Decodes encoded data found in web applications.

• Comparer: Compares different versions of web pages to find changes.

• Proxy: Changes HTTP(S) traffic between the client and server.

Is Burp Suite SAST or DAST?

Burp Suite primarily serves as a Dynamic Application Security Testing (DAST) tool, not a Static Application Security Testing (SAST) tool. To understand why, it's important to know the difference between SAST and DAST.

Analysts conduct Static Application Security Testing (SAST) by examining the source code, binaries, or bytecode of an application without executing it. This approach allows SAST to be conducted early in the development process, focusing on identifying vulnerabilities within the application's code. The primary goal of SAST is to detect coding errors, insecure coding practices, and potential security flaws by scanning the codebase.

On the other hand, Dynamic Application Security Testing (DAST) assesses the security of an application while it is running, simulating attacks to identify vulnerabilities that manifest during execution. Testers usually perform this testing method after deploying the application or running it in a test environment.

DAST focuses on detecting vulnerabilities within the application's runtime environment, such as misconfigurations, insecure communications, and functional flaws that are evident only when the application is operational.

How Does Burp Suite Operate

Burp Suite acts as an intermediary between your browser and the web application server you are testing. It captures and modifies HTTP(S) traffic, providing a sandbox environment for security testers to manipulate and experiment with the application's behavior under various circumstances. This engaging exploration and trial allows an in-depth examination of the application's security protocols.

It helps find possible weak points, like those that could be used in SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF) attacks. These weaknesses might not be seen during regular tests, but with tools like Burp Suite, they can be found and fixed quickly, making the app's security stronger.

Key Features of Burp Suite DAST

Burp Suite DAST provides tools to enhance the security of web applications. These tools employ both automatic and manual testing methods. Here are the main features:

Automated DAST

1. Crawling and Mapping: Automatically visits and logs each web application page to create a detailed map. This is essential for understanding the application's structure and identifying potential vulnerabilities.

2. Vulnerability Scanning: Utilizes various techniques, including fuzzing and checking for insecure handling of user credentials, to detect a wide range of security issues. This comprehensive scanning ensures a thorough assessment of application security.

3. Integration with Development Tools: Designed for seamless integration with development environments, supporting continuous scanning throughout the development lifecycle. This allows for the early detection and resolution of vulnerabilities.

4. Scalability: Provides excellent growth capability, ideal for organizations handling many web applications or using DevSecOps methods. This flexibility ensures good security management, no matter the size or complexity of the application.

Manual DAST

1. Intercepting Proxy: A helpful tool in manual security testing. It lets testers see and change HTTP(S) traffic between the browser and the targeted web application. This way, testers can identify potential threats or vulnerabilities in real-time.

2. Exploration of Vulnerabilities: Allows testers to discover security weaknesses by changing responses sent to servers. This can reveal vital information that automated tools might overlook. It's an effective way to simulate potential attacks and evaluate the server's response.

Augmentation with Other Testing Methods

1. Interactive Application Security Testing (IAST): Improves automatic scans by using interactive testing methods. This allows for more effective identification and resolution of security vulnerabilities in real-time.

2. Out-of-Band Application Security Testing (OAST): Overcomes DAST limitations by tackling hidden and non-simultaneous vulnerabilities that DAST might not detect. This enriches the security testing process by catching threats that traditional methods might miss.

Adaptability and Compatibility

1. Language-Agnostic: Unlike Static Application Security Testing (SAST), DAST does not rely on analyzing source code, making it adaptable to applications developed in various programming languages.

2. Extensions and Customization: The Burp Suite DAST tool provides robust customization via extensions. This allows users to tailor the tool to their specific needs, enhancing the functionality and performance of the scanner.

Reporting and Integration

1. Detailed Reports: The system can generate comprehensive, in-depth reports that detail all the identified vulnerabilities within your network or system. This key feature is designed to aid in the prioritization of potential risks and guide the necessary remediation efforts.

2. Integration with CI/CD Pipelines: One of the standout features of this system is its ability to seamlessly integrate into Continuous Integration/Continuous Deployment (CI/CD) pipelines. This enables the tool to perform automated scanning during the development process.

Cloud-Based and Hybrid Options

1. Cloud-Based Scanning: Our service provides a robust cloud-based scanning capability that emulates various forms of attacks from an external perspective. This design helps identify vulnerabilities that potential external threats could exploit.

2. Self-Hosted Scanning Machines: Our self-hosted scanning machines offer high reconfigurability. We understand that different teams and projects may have unique needs and requirements regarding security scanning. Our self-hosted scanning machines are designed to cater to these diverse needs.
