API library and command-line interface for Banyan Security

Prerequisites

Python 3.7 or 3.8 must be installed.

Installation

Installing the easy way

$ pip install pybanyan

Installing the hard way

$ git clone https://github.com/banyansecurity/pybanyan.git
$ cd pybanyan
$ pip install -r requirements.txt
$ python setup.py install

Usage

This package contains both an API client and a CLI tool. To use either one, you need to generate an API token from the Banyan Command Center.

API library

Here's a sample script that uses the library to print the names of every service registered in Banyan:

from banyan.api import BanyanApiClient

c = BanyanApiClient()
for service in c.services.list():
    print(service.name)

Output:

$ python examples/list_services.py
jira
jupyter
kube
mysql
rds-mysql
rds-pgsql

The BanyanApiClient class accepts optional arguments to specify the API server and refresh token. If not provided, it gets them from environment variables named BANYAN_API_URL and BANYAN_REFRESH_TOKEN.

Full API documentation will be available soon.

Banyan CLI tool

Before you use the CLI, create a file called ~/.banyan.conf in your home directory and paste in your API token:

[banyan]
api_url = https://net.banyanops.com
refresh_token = MY_API_TOKEN

The CLI is invoked with the banyan tool. It contains a number of commands and sub-commands to help you work with policies, roles, services, users, and other objects in Banyan.

Run the banyan tool by itself to see the available commands.

$ banyan
usage: banyan [options] <command> <subcommand> [<subcommand> ...] [parameters]

Each of the commands has multiple subcommands. For example, banyan service allows you to list services, create/delete, enable/disable, etc. Run the command without any subcommand to see the options:

$ banyan service
usage: banyan service [-h]
                      {attach-policy,create,delete,detach-policy,disable,enable,get,list,test,update}
                      ...

optional arguments:
  -h, --help            show this help message and exit

sub-commands:
  {attach-policy,create,delete,detach-policy,disable,enable,get,list,test,update}
    attach-policy       attach a policy to a service
    create              create a new service from a JSON specification
    delete              delete a service
    detach-policy       detach the active policy from a service
    disable             disable a service
    enable              enable a service
    get                 show the definition of a registered service
    list                list registered services
    test                run sanity checks on a service
    update              update an existing service from a JSON specification

To see the full help available for any command, just add the -h or --help option to the end of the command. For example:

$ banyan service attach-policy --help
usage: banyan service attach-policy [-h] [--permissive] [--enforcing]
                                    service_name_or_id policy_name_or_id

positional arguments:
  service_name_or_id  Name or ID of the service to attach a policy to.
  policy_name_or_id   Name or ID of the policy to attach to the service.

optional arguments:
  -h, --help          show this help message and exit
  --permissive        Set the policy to permissive mode (allow all traffic and
