Collect Imperva Incapsula Web Application Firewall logs

This document describes how you can ingest Imperva Incapsula Web Application Firewall logs by setting up a Google Security Operations feed.

For more information, see Data ingestion to Google Security Operations.

An ingestion label identifies the parser which normalizes raw log data to structured UDM format. The information in this document applies to the parser with the IMPERVA_WAF ingestion label.

Configure Incapsula WAF

1. Sign in to my.imperva.com with a reader account.
2. Select Management > Users > Add User. Only users with the account administrator or other required permissions can add a new user to the account. A verification email is sent to the listed addresses of the user and the account administrator.

3. Click the link in the email to verify the email address of the new user and set a login password.

Generate the API ID and API key of reader user

1. Sign in to the my.imperva.com account.
2. Navigate to Management and select Users.
3. Select a user with the reader role.
4. Navigate to Setting and select API Keys.
5. Provide a name for the API key.
6. In the API key will expire in list, select Never.
7. To enable the status, select Status.
8. Click Save.
9. Copy and save the API key and API ID from the dialog that appears. You require the API key and API ID when you configure the Google Security Operations feed.
10. Optional: You can provide a list of approved IP addresses or leave it blank.

Configure a feed in Google Security Operations to ingest Imperva Incapsula Web Application Firewall logs

1. Select SIEM Settings > Feeds.
2. Click Add new.
3. Enter a unique name for the Feed name.
4. Select Third party API as the Source Type.
5. Select Imperva as the Log Type.
6. Provide the API ID and API key in Authentication HTTP Header Configuration.
7. Click Next and then click Submit.

For more information about Google Security Operations feeds, see Google Security Operations feeds documentation. For information about requirements for each feed type, see Feed configuration by type.

If you encounter issues when you create feeds, contact Google Security Operations support.

Field mapping reference

This parser handles both CEF (Common Event Format) and LEEF (Log Event Extended Format) formatted logs from Imperva Web Application Firewall (WAF), as well as JSON formatted logs. It extracts fields, performs data transformations, and maps the data to the UDM based on the log format detected. The parser also handles specific Imperva event types like "Attack Analytics" and various actions like "allow", "block", and "deny", mapping them to appropriate UDM fields.
