    Collect Cambium Networks logs

    Supported in:

    This document explains how to ingest Cambium Networks logs to Google Security Operations using Bindplane. The parser extracts key-value pairs from Cambium Networks switch and router syslog messages, mapping them to a Unified Data Model (UDM). It uses Grok to structure the initial message, KV to separate key-value pairs, and conditional statements to map extracted fields to specific UDM attributes, categorizing events as either "STATUS_UPDATE" or "GENERIC_EVENT".

    Before you begin

    Make sure you have the following prerequisites:

    • Google SecOps instance
    • Windows 2016 or later, or a Linux host with systemd
    • If running behind a proxy, firewall ports are open
    • Privileged access to Cambium Networks devices

    Get Google SecOps ingestion authentication file

    1. Sign in to the Google SecOps console.
    2. Go to SIEM Settings > Collection Agents.
    3. Download the Ingestion Authentication File. Save the file securely on the system where Bindplane will be installed.

    Get Google SecOps customer ID

    1. Sign in to the Google SecOps console.
    2. Go to SIEM Settings > Profile.
    3. Copy and save the Customer IDfrom the Organization Detailssection.

    Install the Bindplane agent

    Windows installation

    1. Open the Command Promptor PowerShellas an administrator.

    2. Run the following command:

        msiexec 
  
 / 
 i 
  
 "https://github.com/observIQ/bindplane-agent/releases/latest/download/observiq-otel-collector.msi" 
  
 / 
 quiet

    Linux installation

    1. Open a terminal with root or sudo privileges.

    2. Run the following command:

       sudo  
sh

    For additional installation options, consult the installation guide .

    Configure the Bindplane agent to ingest Syslog and send to Google SecOps

    1. Access the configuration file:
      • Locate the config.yaml file. Typically, it's in the /etc/bindplane-agent/ directory on Linux or in the installation directory on Windows.
      • Open the file using a text editor (for example, nano , vi , or Notepad).

    2. Edit the config.yaml file as follows:

        receivers 
 : 
  
 udplog 
 : 
  
 # Replace the port and IP address as required 
  
 listen_address 
 : 
  
 "0.0.0.0:514" 
 exporters 
 : 
  
 chronicle/chronicle_w_labels 
 : 
  
 compression 
 : 
  
 gzip 
  
 # Adjust the path to the credentials file you downloaded in Step 1 
  
 creds 
 : 
  
 '/path/to/ingestion-authentication-file.json' 
  
 # Replace with your actual customer ID from Step 2 
  
 customer_id 
 : 
  
< customer_id

 : 
  
 receivers 
 : 
  
 - 
  
 udplog 
  
 exporters 
 : 
  
 - 
  
 chronicle/chronicle_w_labels

    3. Replace the port and IP address as required in your infrastructure.

    4. Replace <customer_id> with the actual customer ID.

    5. Update /path/to/ingestion-authentication-file.json to the path where the authentication file was saved in the Get Google SecOps ingestion authentication file section.

    		read_only_udm.metadata.event_type Determined based on the presence of values in the security_result and host_name fields. If both fields are present, the event type is set to STATUS_UPDATE , otherwise it's GENERIC_EVENT .
    		read_only_udm.security_result.about.resource.attribute.labels.key The value of this field is determined by the parser logic based on the specific key-value pair being processed.
