• Delivers visibility into today’s advanced attacks such as ransomware, business email compromise (BEC), impostor, and credential phishing attacks
• Automates sending of email flter logs from Email Protection to Splunk Enterprise and Splunk Enterprise Security, from one or many sources
• Provides visibility into email activity, threats and data exfiltration by attackers and malicious insiders
• Consolidates reporting and provides comprehensive visibility by correlating email and other data sources in Splunk

Deployment

Single Server Deployment:

In a single server deployment, single instance of Splunk Enterprise functions as data collection node, indexer and search head. In such deployment, install the add-ons Proofpoint Email Security Add-On and Proofpoint TAP SIEM Modular Input. After that, install Proofpoint Email Security App For Splunk.

Distributed Deployment

In a distributed deployment, typically a combination of forwarders are deployed for data collection, separate indexer nodes for data injection and search heads for data visualization are deployed. We recommend installing our TA's on both Forwarder and Search heads and the App on the search head.

Splunk Configuration

Add UDP/TCP input to listen on the port for PPS logs and specify "pps_log" as sourcetype. You can do this from Splunk Admin Console.

  1. Go to "Settings" -> "Data Inputs"
  2. Click on "Add new" action for TCP or UDP input
  3. Enter port and click on "Next"
  4. In "Select sourcetype" search and select "pps_log". Click "Review".
  5. Review config and submit to create a data source.
  6. Check data summary and sourcetypes tab to make sure the logs are being accepted for the pps_log sourcetype.

Changing the Index

By default this app uses the "main" index to look for Proofpoint logs. To change this to an index that the Proofpoint Email Security Add-On uses, you need to edit the get_pps_index macro. Here are the steps:

  1. Navigate to Settings->Advanced Search and select "Search macros"
  2. Change the app context to "Proofpoint Email Security App for Splunk"
  3. Select the macro named "get_pps_index"
  4. Change index=main to the correct index. Please make sure this index matches the one used the Proofpoint Email Security Add-On for Splunk.
  5. Save the configuration.

Proofpoint Email Protection Configuration

On the Proofpoint Email Protection admin console, enable syslog to forward to your Splunk instance

  1. Login to PPS as an admin user and navigate to “Logs and Reports > Log Settings”. Proofpoint on Demand customers please note that this feature requires a separate Remote Syslog license.
  2. Input syslog protocol, host and port numbers
  3. Enable Filter and Mail logs
  4. Click “Save Changes” 

Verification

  1. PPS filter and mail logs are collected by the source type "pps_log" and are mapped to sourcetypes pps_filter_log and pps_mail_log. In the search box you can verify the logs by search for "sourcetype="pps_filter_log" and "sourcetype="pps_mail_log"
  2. To view the dashboards from the splunk home page, click on the Proofpoint Email Security App For Splunk icon. This should take you to PPS Summary Dashboard with latest information.
  3. Explore the built-in dashboards on the "Dashboards" tab
  4. Explore the built-in reports on the "Reports" tab
