1. You must manage accounts for the add-on as a prerequisite. See the Manage accounts for the Splunk Add-on for AWS topic in this manual.
2. Configure AWS services for the Inspector v2 input.
3. Configure AWS permissions for the Inspector v2 input.
4. Configure Inspector v2 inputs either through Splunk Web or configuration files.

Configure Amazon Inspector v2 permissions

You need these required permissions for Inspector v2:

• Describe*
• List*

See the following sample inline policy to configure Inspector v2 input permissions:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "inspector2:Describe*",

Configure an Inspector v2 input using Splunk Web

To configure inputs using Splunk Web:

1. Click Splunk Add-on for AWS in the navigation bar on Splunk Web home.
2. Click Create New Input > Inspector > Inspector (v2).
3. Use the following table to complete the fields for the new input in Splunk Web or in the .conf file:

Argument in configuration file	Field in Splunk Web	Description
account	AWS Account	The AWS account or EC2 IAM role the Splunk platform uses to access your Inspector findings. In Splunk Web, select an account from the drop-down list. In aws_inspector_v2_tasks.conf, enter the friendly name of one of the AWS accounts that you configured on the Configuration page or the name of the automatically discovered EC2 IAM role.
regions	AWS Region	The AWS region that contains the data. In aws_inspector_v2_tasks.conf, enter region IDs in a comma-separated list.
sourcetype	Source type	A source type for the events. Enter a value only if you want to override the default of aws:inspector:v2:findings. Event extraction relies on the default value of source type. If you change the default value, you must update props.conf as well.
index	Index	The index name where the Splunk platform puts the Inspector findings. The default is main.
polling_interval	Pooling interval	The number of seconds to wait before the Splunk platform runs the command again. The default is 300 seconds.

Configure an Inspector v2 input using configuration files

To configure the input using the configuration files, create $SPLUNK_HOME/etc/apps/Splunk_TA_aws/local/aws_inspector_v2_tasks.conf using the following template:

[<name>]
account = <value>
region = <value>
index = <value>
polling_interval = <value>
sourcetype = <value>

The following is an example stanza that collects Inspector v2 findings:

[splunkapp2:us-west-2]
account = splunkapp2
region = us-west-2
index = default
polling_interval = 300
sourcetype = aws:inspector:v2:findings
