How to use NAXSI with elasticsearch to generate whitelist rules

• test elasticsearch: curl -XGET http://elasticsearch:9200/

• create nxapi tabel: curl -XPUT 'http://elasticsearch:9200/nxapi/'

• write stuff to db: nxtool.py -c /etc/nginx/nxapi.json --files=/var/log/nginx/naxsi_error.log

• check command: curl -XPOST "http://elasticsearch:9200/nxapi/events/_search?pretty" -d '{}' or nxtool.py -x -c /etc/nginx/nxapi.json -s 127.0.0.1

• generate whitelist: nxtool.py -c /etc/nginx/nxapi.json -s 127.0.0.1 -f --slack

• generate whitelist for a special uri nxtool.py -c /etc/nginx/nxapi.json -s 127.0.0.1 -f --filter 'uri /core/img/actions/delete.svg' --slack

• save the rule in /etc/nginx/naxsi_whitelist.rules

• tag the rule in the elasticsearch db nxtool.py -c /etc/nginx/nxapi.json -s 127.0.0.1 -w /etc/nginx/naxsi_whitelist.rules --tag
