A website and framework for testing NIDS detection
What is it?
A simple project that aims to centralize testing for detection of malicious events by network intrusion detection systems (NIDS). The tests in this project are built against rulesets, not software. Therefor, if you're using ET Open, coverage for these tests will work.
There are two parts to it:
- A website - that is used to hold some tests/files. It will also hold sub-domains and DNS records for when testing via DNS is required.
- A script - That runs/simulates interaction with the website or with 3rd party websites, meant to be executed on the client for which you want to test coverage of your NIDS sensor.
Usage
Only requirements are curl and nc, which should be included in your distribution.
One-liner to download and execute in interactive mode:
curl -sSL https://raw.githubusercontent.com/3CORESec/testmynids.org/master/tmNIDS -o /tmp/tmNIDS && chmod +x /tmp/tmNIDS && /tmp/tmNIDS
One-liner to download and execute in script mode:
curl -sSL https://raw.githubusercontent.com/3CORESec/testmynids.org/master/tmNIDS -o /tmp/tmNIDS && chmod +x /tmp/tmNIDS && /tmp/tmNIDS -h
Tip: Replace the -h with -N (where N is the test you want - see table below) at the end of the one-liner to automatically run the desired test
Interactive mode
To run tmNIDS in interactive mode without using the one-liner, download and run the script.
After downloading tmNIDS make it executable (chmod +x tmNIDS) and run it (./tmNIDS) to be presented with the wizard:
Script mode
To run tmNIDS in script mode without using the one-liner, download and run the script.
After downloading tmNIDS make it executable (chmod +x tmNIDS) and run it (./tmNIDS -h) to be presented with the script options.
In summary, the usage of ./tmNIDS -N, where N is the number of the test, will run the designated test for you.

Why? What about insert_project_here?
Why - We can check if a NIDS engine is working with a simple rule. In most cases, a ping would do. From that moment on it becomes a matter of rulesets if detection is working or not. The purpose of this project is to quickly verify and showcase detection of as many protocols as possible, while keeping the whole process quick, portable and simple.
Other projects - I'm aware that other websites, projects and scripts exist. I created this one because the existing ones were
- lacking features
- no longer supported
- not portable enough
- too many dependencies
Choose whatever works best for you.
