Collect Dell EMC Isilon NAS logs

Supported in:

This document explains how to ingest Dell EMC Isilon NAS logs to Google Security Operations using Bindplane. The Logstash parser code first uses grok patterns to extract various fields like timestamps, IP addresses, usernames, and file paths from DELL_EMC_NAS syslog messages. Then, it maps the extracted fields to the corresponding attributes within the Unified Data Model (UDM) schema, effectively transforming raw log data into a structured format for analysis.

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 Dell EMC Isilon

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

Install the Bindplane agent on your Windows or Linux operating system according to the following instructions.

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_file_path: '/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: 'DELL_EMC_NAS'
            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 Step 1.

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

Configure Syslog for OneFS Version 7.x:

  1. Sign in to the Dell Isilon using CLI.

  2. Enable auditing using the following commands (replace zone_name with actual host):

    isi audit settings modify --protocol-auditing-enabled yes --audited-zones <zone_names>
isi zone zones modify <zone_name> --audit-success create,delete,read,rename,set_security,write
isi zone zones modify <zone_name> --audit-failure create,delete,read,rename,set_security,write
isi zone zones modify <zone_name> --syslog-audit-events create,delete,read,rename,set_security,write

  5. Open the syslog.conf file using vi, which is located in the /etc/mcp/templates directory.

    vi syslog.conf

  6. Locate the !audit_protocol line and add the following line, replace <bindplane-ip> with the actual Bindplane agent IP address:

    *.* @<bindplane-ip>

  7. Save the syslog.conf file:

    ```bash
