For those APOC commands that retrieve data using HTTP/HTTPS, and or running
Cypher LOAD CSV the request will be sent with Neo4j specific
user-agent/browser identifiers.
Below is an example log from an Apache webservers access log at /var/log/apache2/access.log and includes 4
request made by
192.168.2.38 - - [26/Mar/2018:19:16:52 -0400] "GET / HTTP/1.1" 200 3477 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36"
192.168.2.38 - - [26/Mar/2018:19:17:23 -0400] "GET / HTTP/1.1" 404 3477 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0"
192.168.2.40 - - [26/Mar/2018:19:21:11 -0400] "GET /test.json HTTP/1.1" 200 989 "-" "curl/7.55.1"
192.168.2.40 - - [26/Mar/2018:19:26:37 -0400] "GET /test.json HTTP/1.1" 200 989 "-" "APOC Procedures for Neo4j"
192.168.2.40 - - [26/Mar/2018:19:46:01 -0400] "GET /test.csv HTTP/1.1" 200 502 "-" "NeoLoadCSV_Java/1.8.0_151"
From the above we see that apoc.load.json sent a user-agent of APOC Procedures for Neo4j
and LOAD CSV sent a user-agent of
NeoLoadCSV_Java/1.8.0_151
. Additionally for any Bolt enabled application, for example Neo4j Browser and cypher-shell the
user-agent will be the same since the work is actually being done on the server itself.
As such if your Network Firewall is to only allow HTTP(s) request traffic of the typical known user-agent/browser identifiers, and
reject all other traffic you may encounter where the a request through a typical browser reports data but when using APOC or LOAD CSV
no data is returned.
