Collecting logs for the Imperva-Incapsula WAF app

This section provides instructions on configuring log collection for the Imperva - Incapsula Web Application Firewall app, as well as query samples.

Set up log integration in Imperva Incapsula

To configure log integration, do the following:

1. Log into your my.incapsula.com account.
2. On the sidebar, click Logs > Log Setup.
3. Connection. Select Amazon S3.
4. Next, fill in your credentials:
   • Your S3 Access key, Secret key, and Path, where path is the location of the folder where you want to store the logs. Enter the path in the following format: <Amazon S3 bucket name>/<log folder>. For example: MyBucket/MyIncapsulaLogFolder.
   • Click Test connection to perform a full testing cycle in which a test file will be transferred to your designated folder. The test file does not contain real data, and will be removed by Incapsula when the transfer is complete.
5. Configure the additional options:
   • Format. Select the format for the log files: CEF
   • Compress logs. By default, log files are compressed. Clear this option to keep the logs uncompressed.

For detailed instructions, see here.

Set up in Sumo Logic

To configure log collection for Sumo Logic, do the following:

1. Add a Sumo Logic Hosted Collector
2. Configure Amazon S3 Source.

Installing the Imperva-Incapsula WAF app

To install the app, do the following:

1. Select App Catalog.
2. In the 🔎 Search Apps field, run a search for your desired app, then select it.
3. Click Install App.
   note

   Sometimes this button says Add Integration.

4. Click Next in the Setup Data section.
5. In the Configure section of your respective app, complete the following fields.
   1. Key. Select either of these options for the data source.
      • Choose Source Category and select a source category from the list for Default Value.
      • Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
6. Click Next. You will be redirected to the Preview & Done section.

Post-installation

Once your app is installed, it will appear in your Installed Apps folder, and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query and received since the panel was created. Results will not immediately be available, but will update with full graphs and charts over time.

Viewing Imperva-Incapsula WAF dashboards​

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

• You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
• You can use template variables to drill down and examine the data on a granular level. For more information, see Filtering Dashboards with Template Variables.
• Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.
