NGINX ModSecurity OWASP CRS V0.0
Dashboard to work with ModSecurity and the OWASP Coreruleset.
Dashboard to work with ModSecurity and the OWASP Coreruleset. Especially in a early phase of deploying it to handle and adjust false positives quickly. Depending on the applications behind the waf it is very practical also for maintenance...

## Dependencies
* loki
* nginx error logs (default)
* modsecurity
* OWASP Coreruleset

## How to get the data
I sent the default error logs of NGINX (where modsecurity also writes the information, this dashboard needs) with promtail to a loki instance.

If you need more information. I summarized my setup [here](https://tobisyurt.net/modsecurity-nginx).
