Securing communication to QABS
Now that Perception has been successfully installed and setup. You should secure the communications coming to the Questionmark Assessment Business Services tier. This should be secured to ensure that no malformed messages can be sent to Perception to be processed.
The recommended way of securing communication to QABS is to:
- Limit and filter the information received by QABS
- Only accept information from the current machine (if installed on a single server), or the machine(s) where the Questionmark Presentation Layer for Assessments (QPLA) is installed (if deployed in a multi-tiered setup).
How you secure the communication will depend on which operating system you have installed Perception Server on. For instructions about securing communication, please refer to the following Knowledge Base articles and complete the steps on the machine where QABS has been installed:
- How can I secure access to the QABS virtual directory using IIS 6?
- How can I secure access to the QABS virtual directory using IIS 7?
Once your installation is working correctly, you may want to configure your Perception Server to take advantage of more advanced functionality. For more information on the configuration options available, please refer to the Advanced configuration options chapter.
