AWS Threat Intel

The Threat Intel for AWS App correlates Sumo Logic threat intelligence data with your AWS log data, allowing for real-time security analytics to help detect threats in your environment and protect against cyber-attacks. The Threat Intel for AWS App scans your AWS CloudTrail, AWS ELB and AWS VPC Flow logs for threats based on IP address.

The Sumo Logic Threat Intel lookup database is only available with Sumo Logic Enterprise and Professional accounts, or during a 30-day trial period. The Threat Intel lookup database is not available for Sumo Logic Free accounts.

Collect Logs for the Threat Intel for AWS App

The Threat Intel for AWS App utilizes AWS logs and VPC Flow Logs.

The Sumo Logic Threat Intel lookup database is only available with Sumo Logic Enterprise and Professional accounts, or during a 30-day trial period. The Threat Intel lookup database is not available for Sumo Logic Free accounts.

Configure Collectors and Sources

If you are not already collecting your AWS logs, follow the instructions below to collect data from one or more of these data sources:

• Collect AWS CloudTrail Logs
• Collect AWS ELB Logs

VPC Flow Logs can be published to Amazon CloudWatch Logs and Amazon S3. Each method has advantages. Using an Amazon S3 source is more reliable, while using a CloudFormation template allows you to customize your logs by adding more information and filtering unwanted data. You can use either of the following methods to collect Amazon VPC Flow Logs:

• Using an Amazon S3 source
• Using a CloudFormation template

Installing the Threat Intel for AWS App

The Sumo Logic Threat Intel lookup database is only available with Sumo Logic Enterprise and Professional accounts, or during a 30-day trial period. The Threat Intel lookup database is not available for Sumo Logic Free accounts.

Now that you have set up collection, install the Sumo Logic App for Threat Intel for AWS to use the preconfigured searches and Dashboards that provide insight into your data.

To install the app, do the following:

note

Next-Gen App: To install or update the app, you must be an account administrator or a user with Manage Apps, Manage Monitors, Manage Fields, Manage Metric Rules, and Manage Collectors capabilities depending upon the different content types part of the app.

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. Field Name. If you already have collectors and sources set up, select the configured metadata field name (eg _sourcecategory) or specify other custom metadata (eg: _collector) along with its metadata Field 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 received since the panel was created. Results will not immediately be available but will be updated with full graphs and charts over time.

Viewing Threat Intel dashboards

All Dashboards include filters that you can use in Interactive Mode for further analysis of your Threat Intel data.
