AWS Perimeter Tool

An AWS perimeter checking tool that can be used to look for resources that are publicly accessible, shared with untrusted accounts, have insecure network configurations, and more.

Run checks in a dashboard:

Or in a terminal:

Includes support for:

• Network Access
• Public Access
• Shared Access

Getting started

Installation

Download and install Steampipe (https://steampipe.io/downloads). Or use Brew:

brew tap turbot/tap
brew install steampipe

Install the AWS plugin with Steampipe:

steampipe plugin install aws

Clone:

git clone https://github.com/turbot/steampipe-mod-aws-perimeter.git
cd steampipe-mod-aws-perimeter

Usage

Start your dashboard server to get started:

steampipe dashboard

By default, the dashboard interface will then be launched in a new browser window at https://localhost:9194. From here, you can run benchmarks by selecting one or searching for a specific one.

Instead of running benchmarks in a dashboard, you can also run them within your terminal with the steampipe check command:

Run all benchmarks:

steampipe check all

Run a single benchmark:

steampipe check benchmark.public_access

Run a specific control:

steampipe check control.ec2_instance_ami_prohibit_public_access

Different output formats are also available, for more information please see Output Formats.

Credentials

This mod uses the credentials configured in the Steampipe AWS plugin.

Configuration

Several benchmarks have input variables that can be configured to better match your environment and requirements. Each variable has a default defined in its source file, e.g., perimeter/shared_access.sp, but these can be overwritten in several ways:

• Copy and rename the steampipe.spvars.example file to steampipe.spvars, and then modify the variable values inside that file

• Pass in a value on the command line:

  steampipe check benchmark.shared_access --var='trusted_accounts=["123456789012", "123123123123"]'

• Set an environment variable:

  SP_VAR_trusted_accounts='["123456789012", "123123123123"]' steampipe check control.ram_resource_shared_with_trusted_accounts

  • Note: When using environment variables, if the variable is defined in steampipe.spvars or passed in through the command line, either of those will take precedence over the environment variable value. For more information on variable definition precedence, please see the link below.

These are only some of the ways you can set variables. For a full list, please see Passing Input Variables.
