Build Status

CloudMapper helps you analyze your Amazon Web Services (AWS) environments. The original purpose was to generate network diagrams and display them in your browser. It now contains much more functionality.

On macOS:

# clone the repo
git clone
# Install pre-reqs for pyjq
brew install autoconf automake libtool jq awscli python3
cd cloudmapper/
pipenv install --skip-lock
pipenv shell

On Linux:

# clone the repo
git clone
# (AWS Linux, Centos, Fedora, RedHat etc.):
# sudo yum install autoconf automake libtool python3-devel.x86_64 python3-tkinter jq awscli
# (Debian, Ubuntu etc.):
# You may additionally need "build-essential"
sudo apt-get install autoconf automake libtool python3.7-dev python3-tk jq awscli
cd cloudmapper/
pipenv install --skip-lock
pipenv shell

Run with demo data

A small set of demo data is provided. This will display the same environment as the demo site

python prepare --config config.json.demo --account demo
python webserver

This will run a local webserver at


  1. Configure information about your account.
  2. Collect information about an AWS account.

1. Configure your account

Option 1: Edit config file manually

Copy the config.json.demo to config.json and edit it to include your account ID and name (ex. "prod"), along with any external CIDR names. A CIDR is an IP range such as which means only the IP

Option 2: Generate config file

CloudMapper has commands to configure your account:

python configure {add-account|remove-account} --config-file CONFIG_FILE --name NAME --id ID [--default DEFAULT]
python configure {add-cidr|remove-cidr} --config-file CONFIG_FILE --cidr CIDR --name NAME

This will allow you to define the different AWS accounts you use in your environment and the known CIDR IPs.

2. Collect data about the account

This step uses the CLI to make describe and list calls and records the json in the folder specified by the account name under account-data.

AWS Privileges required

You must have AWS credentials configured that can be used by the CLI with read permissions for the different metadata to collect. I recommend using aws-vault. CloudMapper will collect IAM information, which means you MUST use MFA. Only the collect step requires AWS access.

You must have the following privileges (these grant various read access of metadata):

  • arn:aws:iam::aws:policy/SecurityAudit
  • arn:aws:iam::aws:policy/job-function/ViewOnlyAccess

And also:

    "Version": "2012-10-17",
    "Statement": [
            "Action": [
            "Resource": "*",
            "Effect": "Allow"

Collect the data

Collecting the data is done as follows:

python collect --account my_account


  • api_endpoints: List the URLs that can be called via API Gateway.
  • audit: Check for potential misconfigurations.
  • collect: Collect metadata about an account. More details here.
  • find_admins: Look at IAM policies to identify admin users and roles and spot potential IAM issues. More details here.
  • prepare/webserver: See Network Visualizations
  • public: Find public hosts and port ranges. More details here.
  • sg_ips: Get geoip info on CIDRs trusted in Security Groups. More details here.
  • stats: Show counts of resources for accounts. More details here.
  • wot: Show Web Of Trust. More details here.
