Collect Arista switch logs

Supported in:

Google secops SIEM

This parser extracts fields from Arista switch logs, handling both JSON and syslog formats. It uses grok patterns to parse various log message types, mapping extracted fields to the UDM and enriching events with metadata like event type, severity, and principal/target information based on extracted details.

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.
Installed and accessible Arista EOS 4.23.x and above.
Ensure that you have privileged access on Arista EOS Switch.

Get Google SecOps ingestion authentication file

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

Get Google SecOps customer ID

Sign in to the Google SecOps console.
Go to SIEM Settings > Profile.
Copy and save the Customer ID from the Organization Details section.

Install the Bindplane agent

Windows installation

Open the Command Prompt or PowerShell as an administrator.

Run the following command:

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

Linux installation

Open a terminal with root or sudo privileges.

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 this installation guide.

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

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).

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: ARISTA_SWITCH
            raw_log_field: body

service:
    pipelines:
        logs/source0__chronicle_w_labels-0:
            receivers:
                - udplog
            exporters:
                - chronicle/chronicle_w_labels

Replace the port and IP address as required in your infrastructure.
Replace <customer_id> with the actual customer ID.
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
```

Configuring Syslog in Arista switch

Sign in to the Arista switch.
Go to configuration mode:
```
Arista# config terminal
```

Provide the switch with the following configuration to send logs to the Bindplane agent.

Arista(config)# logging host <bindplane-server-ip> <port-number> protocol [tcp/udp]
Arista(config)# logging trap information
Arista(config)# copy running-config startup-config

* Replace `<bindplane-server-ip>` with Bindplane agent IP address and `<port-number>` with the port configured to listen.

Enter additional configuration for command execution logs:

Arista (config)# aaa accounting commands all console start-stop logging
Arista (config)# aaa accounting commands all default start-stop logging
Arista (config)# aaa accounting exec console start-stop logging
Arista (config)# aaa accounting exec default start-stop logging
Arista (config)# copy running-config startup-config

Enter additional configuration for logon logs:

Arista (config)# aaa authentication policy on-success log
Arista (config)# aaa authentication policy on-failure log
Arista (config)# copy running-config startup-config
