Application security testing (AST) is the process of identifying and mitigating security vulnerabilities in software applications. It is a critical part of the software development lifecycle (SDLC) and helps to protect applications from cyberattacks.

There are many different types of AST, but some of the most common include:

  • Static application security testing (SAST): This type of testing analyzes the source code of an application for security vulnerabilities. It can be performed on the application's code before it is compiled, or on the compiled binary.
  • Dynamic application security testing (DAST): This type of testing sends simulated attacks against an application to identify vulnerabilities in its runtime behavior. It can be performed on the application's live environment, or in a testing environment.
  • Interactive application security testing (IAST): This type of testing combines SAST and DAST by dynamically analyzing the application's source code and runtime behavior. It can be used to identify vulnerabilities that are not detected by either SAST or DAST alone.
  • Application security testing (AST) This type of testing analyzes the application's dependencies for known security vulnerabilities. It can be used to identify vulnerabilities in open-source components that are used in the application.
  • Database security scanning: This type of testing scans the application's database for security vulnerabilities. It can be used to identify vulnerabilities in the database schema, permissions, and data.

The AST process typically involves the following steps:

  1. Planning: The first step is to plan the AST process. This includes identifying the applications that need to be tested, the types of testing that will be performed, and the tools that will be used.
  2. Testing: The next step is to perform the AST. This may involve running SAST, DAST, IAST, SCA, or database security scanning tools.
  3. Analysis: The results of the AST need to be analyzed to identify any security vulnerabilities.
  4. Remediation: Vulnerabilities that are identified need to be remediated. This may involve fixing the code, changing the application's configuration, or updating the application's dependencies.
  5. Reporting: The results of the AST need to be reported to the stakeholders. This includes a list of vulnerabilities that were identified, as well as recommendations for remediation.

AST is an essential part of protecting applications from cyberattacks. By following the process outlined above, organizations can identify and mitigate security vulnerabilities in their applications, and help to protect their data and systems from attack.

Here are some additional tips for conducting effective AST:

  • Use a variety of testing techniques to get a comprehensive view of the application's security.
  • Integrate AST into the SDLC to ensure that security is considered from the start.
  • Automate AST as much as possible to reduce the time and cost of testing.
  • Train developers on secure coding practices to help prevent vulnerabilities from being introduced into the code in the first place.

By following these tips, organizations can improve the security of their applications and reduce their risk of being attacked.
