Collect Proofpoint Email Filter logs

Supported in:

Google secops SIEM

This document explains how to ingest Proofpoint Email Filter logs to Google Security Operations using the Bindplane agent.

Proofpoint Email Protection (PPS) is an email security gateway that provides spam filtering, threat detection, and email policy enforcement. It supports syslog forwarding and CEF log integration for exporting security events and mail transaction logs.

Before you begin

Make sure you have the following prerequisites:

A Google SecOps instance
Windows Server 2016 or later, or Linux host with systemd
Network connectivity between the Bindplane agent and the Proofpoint Protection Server (PPS)
If running behind a proxy, ensure firewall ports are open per the Bindplane agent requirements
Privileged access to the Proofpoint Protection Server (PPS) management console with administrator permissions

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.

Note: This JSON file contains credentials for authenticating the Bindplane agent to Google SecOps.

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.

Note: The customer ID is required for configuring the Bindplane agent exporter.

Install the Bindplane agent

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

Windows installation

Open 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

Wait for the installation to complete.
Verify the installation by running:
```
sc query observiq-otel-collector
```
The service should show as RUNNING.

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

Wait for the installation to complete.
Verify the installation by running:
```
sudo systemctl status observiq-otel-collector
```
The service should show as active (running).

Additional installation resources

For additional installation options and troubleshooting, see the Bindplane agent installation guide.

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

Locate the configuration file

Linux:

sudo nano /opt/observiq-otel-collector/config.yaml

Windows:

notepad "C:\Program Files\observIQ OpenTelemetry Collector\config.yaml"

Edit the configuration file

Replace the entire contents of config.yaml with the following configuration:

receivers:
    tcplog:
        listen_address: "0.0.0.0:514"

exporters:
    chronicle/proofpoint_mail_filter:
        compression: gzip
        creds_file_path: '<CREDS_FILE_PATH>'
        customer_id: '<CUSTOMER_ID>'
        endpoint: <REGION_ENDPOINT>
        log_type: PROOFPOINT_MAIL_FILTER
        raw_log_field: body
        ingestion_labels:
            env: production

service:
    pipelines:
        logs/proofpoint_mail_to_chronicle:
            receivers:
                - tcplog
            exporters:
                - chronicle/proofpoint_mail_filter

Configuration parameters

Replace the following placeholders:

Receiver configuration:
- tcplog: Receives syslog over TCP. Use udplog if you configure UDP transport in PPS.
- 0.0.0.0:514: Listens on all interfaces on port 514. Change the port if needed (for example, 1514 for non-root Linux).
Exporter configuration:
- <CREDS_FILE_PATH>: Full path to ingestion authentication file:
  - Linux: /etc/bindplane-agent/ingestion-auth.json
  - Windows: C:\Program Files\observIQ OpenTelemetry Collector\ingestion-auth.json
- <CUSTOMER_ID>: Customer ID from the Get Google SecOps customer ID step.
- <REGION_ENDPOINT>: Regional endpoint URL:
  - US: malachiteingestion-pa.googleapis.com
  - Europe: europe-malachiteingestion-pa.googleapis.com
  - Asia: asia-southeast1-malachiteingestion-pa.googleapis.com
  - See Regional Endpoints for complete list.

Save the configuration file

After editing, save the file:
- Linux: Press Ctrl+O, then Enter, then Ctrl+X
- Windows: Click File > Save

Restart the Bindplane agent to apply the changes

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

sudo systemctl restart observiq-otel-collector

Verify the service is running:

sudo systemctl status observiq-otel-collector

Check logs for errors:

sudo journalctl -u observiq-otel-collector -f

To restart the Bindplane agent in Windows, choose one of the following options:
- Command Prompt or PowerShell as administrator:
```
net stop observiq-otel-collector && net start observiq-otel-collector
```
- Services console:
  1. Press Win+R, type services.msc, and press Enter.
  2. Locate observIQ OpenTelemetry Collector.
  3. Right-click and select Restart.
  4. Verify the service is running:
```
sc query observiq-otel-collector
```
  5. Check logs for errors:
```
type "C:\Program Files\observIQ OpenTelemetry Collector\log\collector.log"
```

Configure Proofpoint Email Protection syslog forwarding

Option 1: Configure syslog forwarding in Proofpoint PPS

Sign in to the Proofpoint Protection Server (PPS) management console.
Navigate to System > Logs and Reports > Log Settings.
In the Remote Log Settings section, configure the following:
- Protocol: Select Syslog.
- Syslog server: Enter the IP address of the Bindplane agent host (for example, 192.168.1.100).
- Port: Enter 514 (must match the Bindplane agent receiver port).
- Transport: Select TCP (must match the Bindplane agent receiver configuration). TLS is also supported for secure forwarding.
In the Local Log Options section, configure the logging verbosity as needed.
Click Save Changes.

Note: Proofpoint on Demand (PoD) cloud deployments require an additional "Remote Syslog Forwarding" license to send logs from the cloud to an on-premises syslog server via TLS.

Option 2: Configure CEF log integration

Sign in to the Proofpoint Protection Server (PPS) management console.
Navigate to Configuration > Integrations > Integrated SIEM.
Click the SIEM Log Integration tab.
Select Enable export to ArcSight format to activate CEF log integration.
Configure the syslog destination server:
- Host: Enter the IP address of the Bindplane agent host (for example, 192.168.1.100).
- Port: Enter 514 (must match the Bindplane agent receiver port).
Click Save.
Verify that CEF-formatted logs are being received by checking the Bindplane agent logs.
