What Is Application Security Testing

To ensure proper implementation, we’ll also explore common weak points and threats your software applications may face. AST encompasses various techniques and methodologies to identify and mitigate security risks in software. These evaluations typically include code analysis, penetration testing, and vulnerability assessment. Mobile application security testing can use different techniques, typically classified as static analysis, dynamic analysis, or interactive analysis. The interactive approach to security testing combines static and dynamic analysis—this makes it possible to identify known vulnerabilities, and also see if they are actually used in the running application and can be exploited. Find and fix exploitable web application vulnerabilities with automated dynamic application security testing.

AST should be leveraged to test that inputs, connections and integrations between internal systems are secure. IAST tools are the evolution of SAST and DAST tools—combining the two approaches to detect a wider range of security weaknesses. However, they are run web application security practices from within the application server, allowing them to inspect compiled source code like IAST tools do. We’ll show you what application security testing is, highlight key benefits, detail the various types of testing available and showcase how to optimize them.

The need for mobile application security testing

Understanding these common threats and weak points, how to guard against them, and what tools and processes can help is a fundamental part of a robust AppSec strategy. This complete coverage can lead to an overwhelming number of findings, some of which can be false negatives. And, without further scanning of the entire application in a running environment, there is no way to validate the fixes. With increased use, in addition to mobile apps processing and storing financial, medical and personal information, customers expect a high level of security and great UX to be delivered by the app. Learn how you can reduce cost, improve security, and achieve faster time to market by regularly scanning your mobile app.

  • Keeping track of the directory or call tree of the application and all the access points can be useful during active testing.
  • Application security testing can be static, dynamic, or interactive, and it can be manual, automated, or a combination of both.
  • Steps can be taken, however, to remove those risks that are easiest to remove and to harden the software in use.
  • This gives the testing team a better way to address genuine vulnerabilities and reduce the time it takes to investigate false positives.
  • This process allows experts to identify subtle security issues, including race conditions, insecure cryptographic implementations, or business logic flaws, which automated tools may overlook.

Depending on the situation, developers may perform their own SAST, while external penetration testers perform DAST. Dynamic Application Security Testing (DAST) is a form of black box security testing where the security testers do not know the underlying architecture of an application. But the modern model of DevSecOps promotes testing as early and often as possible in the SDLC. Your best practices should be to test whenever you feasibly can to help detect issues early, so they can be remediated before they become a bigger problem that costs time, money, and rework efforts later.

Traditional, rule-based WAFs  are a high-maintenance tool that require organizations to meticulously define a rule set that matches their specific traffic and application patterns.

Static Application Security Testing (SAST)

Application security testers can verify that the databases are properly configured, maintained, and protected against advanced persistent threats, unauthorized access, and sensitive data exposures. Security testing for applications is commonly known by two types – static application security testing (SAST) and dynamic application security testing (DAST). However, there are various tools and techniques related to application security testing, offering several more options to conduct application security testing beyond SAST and DAST.

Because legacy testing tools only provide a snapshot in time, they can’t keep up with today’s agile software development lifecycle processes or the many devices that run software in production. Similarly, strategies such as penetration testing, a form of ethical hacking, are only able to find a fraction of an application’s vulnerabilities. Finally, it’s important to note that automated application security testing can be augmented with manual penetration testing services. This hybrid approach is considered a best practice for comprehensive web application security testing.

When a web app fails to validate that a user request was intentionally sent, it may expose data to attackers or enable remote malicious code execution. DAST tools can be used to conduct large-scale scans simulating a large number of unexpected or malicious test cases and reporting on the application’s response. Having discussions and reviews of code is always advised, as you may have missed something or there may be a way to make the code more efficient and secure. In addition you can use tools like SonarCloud to automatically comment and analyze your pull request changes.

Sonarlint is an extension that can be installed in most code editors and will highlight potential issues as the code is written. SonarCloud can be used as part of your build, code review and quality gate process, it will analyze each commit and provide confidence that vulnerable code cannot make its way to production. In this article, we will explore the importance of implementing security testing, including the benefits it provides, and best practices for ensuring its effectiveness.

This gives the testing team a better way to address genuine vulnerabilities and reduce the time it takes to investigate false positives. It is natural to focus application security testing on external threats, such as user inputs submitted via web forms or public API requests. However, it is even more common to see attackers exploit weak authentication or vulnerabilities on internal systems, once already inside the security perimeter.

Automated application security testing is the only way to achieve these goals is to ensure the security of sensitive data or offer a bug-free and threat-free experience for customers and employees who use applications. By leveraging SAST, DAST, MAST, IAST, RASP, and SCA tools, developers can smoothly run their app irrespective of using third-party open-source codes. Contrast is the only solution that can identify vulnerable components, determine if they are actually used by the application, and prevent exploitation at runtime. MAST tools combine static analysis, dynamic analysis and investigation of forensic data generated by mobile applications. They can test for security vulnerabilities like SAST, DAST and IAST, and in addition address mobile-specific issues like jailbreaking, malicious wifi networks, and data leakage from mobile devices. Like DAST, interactive application security testing (IAST) focuses on application behavior during runtime.
