This library is a light wrapper around boto, to be used to assist in enumerating assets when dealing with multiple accounts and all regions.

Consider the use case:

I want to scan all external AWS assets we have.

Well what if you have 11 AWS Accounts, each (currently) with 9 regions? Then it becomes a pain to have to loop through al these accounts/regions when you want to do simple things.

This library just wraps boto to help.

For some sample basic scripts, see this script repo.

You can install via pip directly from Github

pip install git+https://github.com/jfalken/aws_enumeration_lib.git

Most method names are self explanatory, however more detailed docs will be added here.

import yaml  # pip install pyyaml 
from ase import AwsSecurityEnumerator as ASE

# load config dictionary
config = yaml.load(open('config.yaml'))

# init the object
ase = ASE(config)

For example, get all public hostnames for all instances in all accounts and regions. Then use this to feed a scanner or whatever.

instances = ase.get_all_instances()  # all accounts, all regions
public_hosts = [i.public_dns_name for i in instances]

The configuration dictionary must be in the format:

{'aws_accounts': [{'name': 'AWS_Account_1',
                   'key': 'AKIA...',
                   'secret': 'xxx_secret_key_xxx'},
                  {'name': 'AWS_Account_2',
                   'key': 'AKIA...',
                   'secret': 'xxx_secret_key_xxx'},

The scoped credentials need read-only permissions, for example, something like listed here. You can (and should) restrict the credentials for only those services you will actually be reading.

I prefer to load credentials in a yaml file. The file config.yaml in this repo is provided as an example. When loaded via pyyaml (as in the examples), the yaml file will translate into the dict above.
