This article is intended for development professionals who want to improve the security of their code, whether they want to become a more well-rounded developer or to pass gateways for code deployment to upper environments. In addition, quality assurance (QA) professionals may provide a means to test code during functional testing, which is particularly effective for discovering vulnerabilities in code other security testing methods do not expose. By leveraging Selenium IDE with IBM Security AppScan Enterprise, this process becomes automated and, therefore, simplified. Overall, the software development life cycle (SDLC) is improved.
Selenium IDE is an automation tool for web application testing. You install it as a Mozilla Firefox browser plug-in, where it provides an easy-to-use user interface (UI) for recording functional tests.
Installing Selenium IDE
Installation of Selenium IDE is simple: From the download site (see Resources for a link), beneath Selenium IDE, select the latest download (see Figure 1). The current tag as of this writing is 2.4.0, released on 16 September 2013. Install the plug-in, then allow Firefox to restart.

IBM Security AppScan Enterprise Manual Explorer Tool
Manual Explorer Tool is a feature within IBM Security AppScan Enterprise 8.7. You download it from the IBM Security AppScan Enterprise console and install it as a Windows® executable file. It actually functions as a proxy, allowing you to record traffic and save it in the IBM Security AppScan Enterprise format .htd. After it is saved, the traffic file can be directly imported to scan jobs using the IBM Security AppScan Enterprise console.
Installing the Manual Explorer tool
To install the tool, simply log in to the IBM Security AppScan Enterprise console and create or edit a scan job. Complete the following steps to download and install the tool to your local machine:
- Download the Manual Explorer tool:
- Log in to the IBM Security AppScan Enterprise console, and create a new scan job.
- Under EXPLORE, click the What to Scan link.
- For the Starting URL, enter http://demo.testfire.net/bank/login.aspx. Click Add, then click Apply.
- Under Manual Explorer, proceed as if to perform
a manual explore using the plug-in, but instead select the
Use manual explorer tool or AppScan Standard explore
data file option, as shown in Figure 2.
Figure 2. Downloading the Manual Explorer tool
- Click the Download link, and save the Manual Explorer tool executable to your local machine.
- Click Cancel at the bottom right, then click Save to save your scan job for later use.
- Invoke the installer for ManualExplorerSetup.exe, and follow the prompts to install it locally.
See Figure 3.

So what's the point?
Security testing is now integrated into the SDLC. QA testers can leverage Selenium IDE to run their test cases and while doing so perform security checks inside the process. This means that the organization's security team will have more time to spend actually addressing the vulnerabilities and spend less time on the administrative tasks associated with running web application scans. It also means that the organization will benefit from a more comprehensive sweep of web applications for security vulnerabilities, resulting in a greatly decreased vulnerability footprint.
Figure 7 illustrates the issues discovered from the Selenium IDE test case.

This article explained how to couple automated functional testing of web applications with DAST in few manual steps. Selenium IDE is an enabling technology for QA testers and developers that allows recording of functional test sessions in the web application for future replay. Instead of having to manually test the web application functions every time a change is made, you can simply run the Selenium IDE test case again. Further, you can create multiple functional tests with Selenium IDE and execute them in order as an entire test suite. This is a powerful tool for automation.
