Sample Guide ELK Deployment

Install Requirements-ELK Node *SAMPLE*

The following instructions should be utilized as a Sample Guide in the absence of an existing ELK Cluster/Node. This will cover a Debian example install guide of a stand-alone node of Elasticsearch & Kibana.

While Logstash is included in this install guide, it it recommended that a seperate host pulling the VulnWhisperer data is utilized with Logstash to ship the data to the Elasticsearch node.

Please note there is a docker-compose.yml available as well.

Debian: (

sudo apt-get install -y default-jre
wget -qO - | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-5.x.list
sudo apt-get update && sudo apt-get install elasticsearch kibana logstash
sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service
sudo /bin/systemctl enable kibana.service
sudo /bin/systemctl enable logstash.service

Elasticsearch & Kibana Sample Config Notes

Utilizing your favorite text editor:

  • Grab your host IP and change the IP of your /etc/elasticsearch/elasticsearch.yml file. (This defaults to 'localhost')
  • Validate Elasticsearch is set to run on port 9200 (Default)
  • Grab your host IP and change the IP of your /etc/kibana/kibana.yml file. (This defaults to 'localhost') Validate that Kibana is pointing to the correct Elasticsearch IP (This was set in the previous step)
  • Validate Kibana is set to run on port 5601 (Default)

Start elasticsearch and validate they are running/communicating with one another:

sudo service elasticsearch start
sudo service kibana start


sudo systemctl start elasticsearch.service
sudo systemctl start kibana.service

Logstash Sample Config Notes

  • Copy/Move the Logstash .conf files from /VulnWhisperer/logstash/ to /etc/logstash/conf.d/
  • Validate the Logstash.conf files input contains the correct location of VulnWhisper Scans in the input.file.path directory identified below:
input {
  file {
    path => "/opt/vulnwhisperer/nessus/**/*"
    start_position => "beginning"
    tags => "nessus"
    type => "nessus"
  • Validate the Logstash.conf files output contains the correct Elasticsearch IP set during the previous step above: (This will default to localhost)
output {
  if "nessus" in [tags] or [type] == "nessus" {
    #stdout { codec => rubydebug }
    elasticsearch {
      hosts => [ "localhost:9200" ]
      index => "logstash-vulnwhisperer-%{+YYYY.MM}"
  • Validate logstash has the correct file permissions to read the location of the VulnWhisperer Scans

Once configured run Logstash: (Running Logstash as a service will pick up all the files in /etc/logstash/conf.d/ If you would like to run only one logstash file please reference the command below):

Logstash as a service:

sudo service logstash start


sudo systemctl start logstash.service

Single Logstash file:

sudo /usr/share/logstash/bin/logstash --path.settings /etc/logstash/ -f /etc/logstash/conf.d/1000_nessus_process_file.conf
You can’t perform that action at this time.
