30% of the security breaches that end in information theft have a web application as an entry. In this article, learn how to improve the security of the applications that your company develops by running IAST or interactive security tests.
How do IAST tests work?
Interactive application security tests or IAST, are security tests that combine the benefits of SAST and DAST tests, they are performed in a similar way to DAST tests where it is required that the application is already installed on an application server.
But unlike DAST tests, to run an IAST test it is required to install an agent to the application server, this agent monitors everything that happens in the application in real time: http calls to the server, responses from the server, libraries used, connections to data bases and all function executions.
This real-time monitoring allows IAST tests to locate where in the code the vulnerabilities found in the penetration test are located and allows developers to correct the findings faster because they know precisely the location of the vulnerability in the source code and a remediation guide, similar to a SAST test.
Advantages of IAST testing
The IAST security tests have a higher precision than the SAST and DAST tests because they benefit from the monitoring of the execution in real time and their level of false positives is lower than the SAST and DAST tests, also, they allow finding vulnerabilities in third-party libraries used by our application, increasing the coverage of the review to external dependencies, functionality that the SAST tests do not offer.
Additionally, IAST security testing is perfectly suited to new agile and devops methodologies and has the flexibility that it can be used in all phases of the software development lifecycle.
Now you know why IAST tests are the fastest and most effective option to detect vulnerabilities in web applications, providing all the benefits of SAST and DAST tests but with a lower investment.
