What is Dynamic Application Security Testing (DAST)?
Dynamic Application Security Testing (DAST) is a process that actively performs penetration testing on active apps to find any potential security flaws.
Many crucial business operations are now powered by web applications, from internal financial systems to external e-commerce sites. These online apps can help businesses develop fast, but they also frequently include vulnerabilities that, if not found and fixed, might lead to an expensive and disastrous data breach.

How does DAST function?
Once the programme has passed its previous life phases and enters production or runtime, DAST takes place. DAST tests web-enabled programmes' exposed HTTP and HTML interfaces for non-web protocols and data tampering, such as remote procedure calls (RPC) and session initiation protocols (SIP).
DAST is a "black box test," which means it is carried out from without the programme and has no access to its internal source code or architectural details. As a consequence, by attacking the programme using the same methods a hacker would, the test finds weaknesses. To find risks like cross-site scripting (XSS) or SQL injection, a DAST will use a fault injection approach, which involves injecting malware into the software (SQLi).
Importance of DAST
The danger of a cybercrime rises along with the usage of programmes to improve websites. Early in the SDLC, web application security must be given top importance. DAST is being used by businesses as a reaction to the rising incidence of cybercrime. DAST tools' runtime testing can identify risks or vulnerabilities that occasionally become apparent only after an app is in use, thereby defending the programme against outside attacks.
Benefits of DAST
1. An application's static analysis (SAST) does not offer any data or test cases on how memory is consumed and managed in the application. While in dynamic testing (DAST), it will assist in identifying the various RAM regions that are easily exploitable. Different payloads will be executed in a database or website during testing using the DAST approach, and an attempt will be made to directly execute them into memory. By immediately executing the payload to the CPU and RAM memory, this will aid in measuring the memory use. DAST directly aids in assessing whether memory utilization is being exploited in this manner.
2. The usage of an encryption technique is required by many new government rules as well as industry standards in order to safeguard important application operations and protect sensitive or confidential user data. Instead of examining the robust encryption mechanism in use, DAST attempts to circumvent it in order to assess the potential effects on company operations should any attackers succeed in doing so. Similar to APIs, the authentication process uses a variety of encryption techniques. The DAST technique mimics the approach taken by an attacker who is more intent on directly disabling or getting around the encryption system in use.
3. Using malicious code to interact with the application and log in as the superuser on the rooted device, dynamic testing may check whether the user has the right to access various resources that are permitted. Static testing is unable to identify this security situation, but dynamic testing is able to do so. when a web application contains a weak plugin that, if successfully executed, allows access to a privileged user at a higher level. DAST will be helpful in testing the live online application, however SAST will not be able to identify it because it focuses on scanning the source code of the web application, making it ineffective for testing such scenarios.

4. An application's performance won't become apparent until it is running. The amount of resources used by the CPU and RAM cannot be determined in a static study, but they may be examined during dynamic testing and compared to a benchmark used by the industry. Using the DAST approach, we can monitor the CPU and RAM use while running various payloads in the database. This will assist in monitoring resource use because the payload will be executed directly on the CPU and RAM memory. An application's backend security is a crucial component of the overall security plan. Attackers have a variety of opportunities to steal authentication and authorization tokens and take advantage of the implicit confidence that the backend places in the application when it communicates with it. The area of dynamic application security testing includes several scenarios. Test cases for several vulnerabilities, including cross-site scripting and SQL injection, are available here. With the use of various payloads that we may replay to provide the user access, we can obtain the user's session cookies.
