Altimeter

Altimeter is a system to graph and scan AWS resources across multiple AWS Organizations and Accounts.

Altimeter generates RDF files which can be loaded into a triplestore such as AWS Neptune for querying.

Quickstart

Installation

pip install altimeter

Configuration

Altimeter's behavior is driven by a toml configuration file. A few sample configuration files are included in the conf/ directory:

• current_single_account.toml - scans the current account - this is the account for which the environment's currently configured AWS CLI credentials are.
• current_master_multi_account.toml - scans the current account and attempts to scan all organizational subaccounts - this configuration should be used if you are scanning all accounts in an organization. To do this the currently configured AWS CLI credentials should be pointing to an AWS Organizations master account.

To scan a subset of regions, set the region list parameter regions in the scan section to a list of region names.

Required IAM permissions

The following permissions are required for a scan of all supported resource types:

acm:DescribeCertificate
acm:ListCertificates
cloudtrail:DescribeTrails
dynamodb:DescribeContinuousBackups
dynamodb:DescribeTable
dynamodb:ListTables
ec2:DescribeFlowLogs
ec2:DescribeImages
ec2:DescribeInstances
ec2:DescribeInternetGateways
ec2:DescribeNetworkInterfaces
ec2:DescribeRegions
ec2:DescribeRouteTables
ec2:DescribeSecurityGroups
ec2:DescribeSnapshots
ec2:DescribeSubnets

Additionally if you are doing multi-account scanning via an MPA master account you will also need:

organizations:DescribeOrganization
organizations:ListAccounts
organizations:ListAccountsForParent
organizations:ListOrganizationalUnitsForParent
organizations:ListRoots

Generating the Graph

Assuming you have configured AWS CLI credentials (see https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html), run:

altimeter <path-to-config>

This will scan all resources in regions specified in the config file.

The full path to the generated RDF file will printed, for example:

Created /tmp/altimeter/20191018/1571425383/graph.rdf

This RDF file can then be loaded into a triplestore such as Neptune or Blazegraph for querying.
