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 ID from the Organization Details section.

Install the Bindplane agent

Windows installation

  1. Open the Command Prompt or PowerShell as 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 -c "$(curl -fsSlL https://github.com/observiq/bindplane-agent/releases/latest/download/install_unix.sh)" install_unix.sh
    

Additional installation resources

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>
            endpoint: malachiteingestion-pa.googleapis.com
            # Add optional ingestion labels for better organization
            ingestion_labels:
                log_type: 'CAMBIUM_NETWORKS'
                raw_log_field: body
    
    service:
        pipelines:
            logs/source0__chronicle_w_labels-0:
                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.

Restart the Bindplane agent to apply the changes

  • To restart the Bindplane agent in Linux, run the following command:

    sudo systemctl restart bindplane-agent
    
  • To restart the Bindplane agent in Windows, you can either use the Services console or enter the following command:

    net stop BindPlaneAgent && net start BindPlaneAgent

severity read_only_udm.security_result.severity Mapped from the log message using the grok pattern. alert maps to HIGH, warn maps to MEDIUM, everything else maps to LOW.
severity read_only_udm.security_result.severity_details Mapped from the log message using the grok pattern. Preserves the original severity value.

timestamp read_only_udm.metadata.event_timestamp Extracted from the log message using the grok pattern and converted to a timestamp.
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. The possible values are: Internet_Access_Provider, manufacturer, channel, received_signal_strength_indicator, and encryption_standard.
read_only_udm.security_result.description If the severity is warn this field takes the value of kv_fields, otherwise it takes the value of ids_status.
