Collect NetApp SAN logs

Supported in:

This document explains how to ingest NetApp SAN logs to Google Security Operations using a Bindplane agent. The parser extracts fields from NetApp SAN logs using Grok patterns, then maps those extracted fields to the Google SecOps UDM, enriching the data with static vendor and product information for standardized security analysis. If the log entry doesn't match the expected pattern, it's dropped as having no security value.

Before you begin

  • Ensure that you have a Google SecOps instance.
  • Ensure that you are using Windows 2016 or later, or a Linux host with systemd.
  • If running behind a proxy, ensure firewall ports are open.
  • Ensure that you have privileged access to NetApp SAN.

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

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

  1. Access the configuration file:

    1. Locate the config.yaml file. Typically, it's in the /etc/bindplane-agent/ directory on Linux or in the installation directory on Windows.
    2. 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: NETAPP_SAN
            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

Configure Syslon in NetApp SAN

  1. Sign in to the NetApp SAN web UI.
  2. Go to Configuration > Monitoring > Audit and syslog server.
  3. Click Configure external syslog server or Edit external syslog server.
  4. Provide the following configuration details:
    • Host: enter the Bindplane IP address.
    • Port: enter the Bindplane port number; for example, 514 for UDP.
    • Protocol: Select UDP.
  5. Click Continue.
  6. Enable and select the following Syslog content:
    • Send audit logs: enable and set Severity:Informational(6), facility:local7.
    • Send security events: enable and set Severity:Passthrough, facility:Passthrough.
    • Send application logs: keep this disabled.
  7. Click Continue.
  8. Send a log test message.
  9. Click Save.

UDM Mapping Table

Log Field UDM Mapping Logic
datetime metadata.event_timestamp.seconds Extracted from the log message using the grok pattern %{SYSLOGTIMESTAMP:datetime} and converted to epoch seconds.
desc metadata.description Extracted from the log message using the grok pattern %{GREEDYDATA:desc}.
ip principal.ip Extracted from the log message using the grok pattern %{IP:ip}.
log_level Used to determine the value of security_result.severity.
port principal.port Extracted from the log message using the grok pattern %{INT:port} and converted to an integer.
request security_result.summary Extracted from the log message using the grok pattern %{DATA:request}.
userid principal.user.userid Extracted from the log message using the grok pattern %{WORD:userid}.
N/A metadata.event_type Set to STATUS_UPDATE by the parser.
N/A metadata.log_type Populated from the incoming log metadata.
N/A metadata.product_name Set to Storage Area Network by the parser.
N/A metadata.vendor_name Set to NetApp by the parser.
N/A security_result.severity Set to ERROR if log_level is Error.
