Juniper SRX Firewall

Ship your Juniper SRX firewall logs using Filebeat to your Logit.io Stack

Configure a Juniper SRX firewall to ship logs via Filebeat to your Logit.io stacks via Logstash.

Send Your DataLogsFirewallsJuniper SRX Firewall Guide

Follow this step by step guide to get 'logs' from your system to Logit.io:

Step 1 - Install Filebeat

To get started first follow the steps below:

Older versions can be found here filebeat 7, filebeat 6, filebeat 5

Step 2 - Configure Juniper SRX Logging

Configure the Juniper SRX firewall to log to a syslog server:

Ensure that your Juniper firewall is configured to send logs to your Filebeat server, meeting the required configuration criteria:

  • Log format: syslog
  • Send over: UDP
  • IP Address: FILEBEAT-IP-ADDRESS
  • Port: 514

Step 3 - Configure Filebeat.yml

The configuration file below is pre-configured to send data to your Logit.io Stack.

Copy the configuration file below and overwrite the contents of the Filebeat configuration file typically located at /etc/filebeat/filebeat.yml

# ============================== Filebeat inputs ===============================
filebeat.inputs:

- type: udp
  max_message_size: 10MiB
  host: "0.0.0.0:514"
  enabled: true

  fields:
     type: juniper
  fields_under_root: true
  encoding: utf-8
  ignore_older: 12h

# ================================== Outputs ===================================
output.logstash:
    hosts: ["your-logstash-host:your-ssl-port"]
    loadbalance: true
    ssl.enabled: true

If you’re running Filebeat 7, add this code block to the end. Otherwise, you can leave it out.

# ... For Filebeat 7 only ...
filebeat.registry.path: /var/lib/filebeat

If you’re running Filebeat 6, add this code block to the end.

# ... For Filebeat 6 only ...
registry_file: /var/lib/filebeat/registry

It’s a good idea to run the configuration file through a YAML validator to rule out indentation errors, clean up extra characters, and check if your YAML file is valid. Yamllint.com is a great choice.

Step 4 - Validate configuration

DEB/RPM

sudo filebeat -e -c /etc/filebeat/filebeat.yml

macOS

sudo ./filebeat -e -c filebeat.yml --strict.perms=false

You’ll be running filebeat as root, so you need to change ownership of the configuration file and any configurations enabled in the modules.d directory, or run filebeat with --strict.perms=false as shown above. Read more about how to change ownership.

Windows

cd <EXTRACTED_ARCHIVE>
.\filebeat.exe -e -c filebeat.yml

Linux

sudo ./filebeat -e -c filebeat.yml --strict.perms=false

You’ll be running filebeat as root, so you need to change ownership of the configuration file and any configurations enabled in the modules.d directory, or run filebeat with --strict.perms=false as shown above. Read more about how to change ownership.

If the yml file is invalid, filebeat will print an `error loading config file` error message with details on how to correct the problem. If you have issues starting filebeat see "How To Diagnose No Data In Stack" below to troubleshoot.

Step 5 - Start filebeat

Start or restart filebeat to apply the configuration changes.

Step 6 - Launch Logit.io to view your logs

Now you should view your data:

Step 8 - Juniper SRX Overview

Enterprises can rely on Juniper SRX firewalls for advanced network security in protecting against cyber threats and unauthorized access. However, to effectively monitor and analyze network activity, a reliable and efficient log management solution is essential. Luckily, the Juniper SRX firewalls generate logs that capture valuable information about network traffic, threats, and user activity.

Organizations can effectively manage these logs by using Filebeat, an open-source shipping tool, to send logs from Juniper SRX firewalls to various destinations, including Elasticsearch, Logstash, and Kibana. Filebeat's reliability and minimal memory footprint make it a popular choice for sending logs to different destinations. It's also compatible and easy to use.

To send Juniper SRX firewall logs to Filebeat, organizations need to configure the firewall to forward logs to a syslog server, and then use Filebeat to collect and forward log data to Elasticsearch or other destinations. This involves setting up a syslog server to receive the logs, configuring the firewall to send logs to the syslog server, and configuring Filebeat to collect and forward the logs from the syslog server to Elasticsearch or other destinations.

Filebeat offers a filebeat.yml wizard to help users avoid complex logging concerns, such as large registry files and frequent errors encountered when handling deleted or renamed log files. Additionally, users can opt to use our Hosted ELK service to simplify tracking numerous pipelines using this shipper.
