“Yes, I know what applications we have publicly exposed.”
How many times have you said that with confidence? I bet not too many. With the rapid pace of development that engineering teams can work at, it is becoming increasingly difficult to know what apps you have exposed to the internet, adding potential security risks to your organization.
This is where InsightAppSec’s new application discovery feature, powered by Rapid7’s Project Sonar, can help to fill in these gaps.
What exactly is application discovery?
Using the data supplied by Project Sonar — which was started almost a decade ago and conducts internet-wide surveys across more than 70 different services and protocols — you can enter a domain within InsightAppSec and run a discovery search. You will get back a list of results that are linked to that initial domain, along with some useful metadata.
We have had this feature open as a beta for various customers and received real-world examples of how they used it. Here are two key use cases for this functionality.
Application ports
After running a discovery scan, one customer noticed that a “business-critical web application was found on an open port that it shouldn’t have been on.” After getting this data, they were able to work with that application team and get it locked down.
App inventory
Various customers noted that running a discovery scan helped them to get a better sense of their public-facing app inventory. From this, they were able to carry out various tasks, including “checking the list against their own list for accountability purposes” and “having relevant teams review the list before attacking.” They did this by exporting the discovery results to a CSV file and reviewing them outside of InsightAppSec.
How exactly does it work?
Running a discovery search shouldn’t be difficult, so we’ve made the process as easy as possible. Start by entering a domain that you own, and hit “Discover.” This will bring back a list of domains, along with their IP, Port, and Last Seen date (based on the last time a Sonar scan has found it.)
From here, you could add a domain to your allow list and then run a scan against it, using the scan config setup process.
If you see some domains that you are not sure about, you might decide that you need to know more about the domains before you run a scan. You can do this by exporting the data as a CSV and then running your own internal process on these before taking any next steps.
How do I access application discovery?
Running a discovery scan is currently available to all InsightAppSec Admins, but Admins can grant other users or sets of users access to the feature using the InsightPlatform role-based access control feature.
