pcpi 0.3.0

Python Package for making API calls to the Prisma Cloud API using best practices.

Prisma Cloud Python Integration - PCPI

Python3 toolkit for Prisma Cloud APIs

Disclaimer

This tool is supported under "best effort" policies. Please see SUPPORT.md for details.

Installation

This tool requires Python3. Please visit https://www.python.org/downloads/ for Python3 installation guides.

Depending on your environment, you may have to install the pcpi library in a different way.

This tool only needs to be installed in ONE of these ways, do not run all of these commands.

Run one of the following commands in a terminal/command prompt:

Mac/Linux

• pip3 install pcpi
• python3 -m pip install pcpi
• pip install pcpi

Windows

• py -m pip install pcpi
• python -m pip install pcpi
• pip install pcpi
• pip3 install pcpi
• python3 -m pip install pcpi

Quick Start

1. Create a file with a text editor of your choice (I recommend VS Code). Name this file script.py
2. Open the file and add these lines:

from pcpi import session_loader
#load_config will create a config file if one does not exist. Default path is ~./prismacloud/credentails.json
session_managers = session_loader.load_config()
#load_config returns a list of session_manager objects. If only one is needed, index the list at position 0 
# to get the first and only session_manager.
#load_config() will create a credential file for you if the default path or the specified path does not exist.
#load_config() accepts credentials for SaaS and Self hosted Prisma Cloud and smartly returns either a SaaS session manager or
# an On-Prem session manager.
session_man = session_managers[0]
#If you supplied credentials for Prisma Cloud SaaS, you can create a CSPM Session Or a CWP Session.
#create_cspm_session(), create_cwp_session()
#If you supplied credentials for Prisma Cloud Self Hosted/On-prem, you will only be able to create CWP sessions.
#create_cwp_session()
cspm_session = session_man.create_cspm_session()

res = cspm_session.request('GET', '/cloud')

print(res.json())

3. Run the script by opening a terminal/command prompt, navigating to your directory/folder then using the Python command and specifying the name of your Python script. You may have to use a different name for the Python program depending on your environment.

Mac/Linux

python3 script.py

Windows

py script.py

4. When running this script for the first time, the pcpi library will prompt you for your Prisma Cloud credentials. Follow the prompts and if all goes well, you should see some SUCCESS messages being logged to your terminal. If you see ERRORs, then you may have to disable any VPNs you are connected too and you need to ensure you have valid Prisma Cloud credentials.

5. This example script calls the /cloud endpoint. After this script runs, you should see data from your tenant about cloud accounts in JSON format.

Scripting Setup Guide

1. Import pcpi into your python project

2. Create a session manager directly or by using a session loader
   2a) Session Loader arguments are all optional.
   2b) Specify a file path, if file_path variable is excluded, the default credential path will be used.
   2c) If the credentials file does not exist, the script will set it up for you at the specified or default file path

3. Create a CSPM or CWP session by using the session manager.

4. Use the created session object to make API requests

5. Run the script

python3 <yourscriptname>.py

import pcpi

session_loader = pcpi.session_loader

Prisma Cloud Python Integration Documentation and Examples

Session Loaders

The session loader is a module that has functions for loading Prisma Cloud credentials from a file, environment variables, or from the user into your program. This ensures you get your script up and running as quickly as possible.

The session loader module has functions that return a session manager or session manager list that is used to create a CSPM, CWP, or an On-Prem CWP session. The session manager is used to create the Prisma Cloud session object that you will be using to make API calls.

Examples

SaaS Examples

from loguru import logger
loguru_logger = logger

from pcpi import session_loader

#--DEFAULT OPTION--
#Defaults to a file named '~./prismacloud/credentials.json'
session_manager_default = session_loader.load_config(logger=loguru_logger)

#--CUSTOM OPTION--
#File must be a json file 
#If a file that does not exist is specified, the script will build one. Only creates end file, not directory structure. That setup is up to you.
#If using default file path, load_config() will create the ~/.prismacloud/credentials.json file structure.
session_managers = session_loader.load_config(file_path='~/secrets/my_secrets.json')
session_manager = session_managers[0]

cspm_session = session_manager.create_cspm_session()
cwp_session = session_manager.create_cwp_session()

response = cspm_session.request('GET', '/cloud')

print(response.json())

For SaaS CSPM and CWP and Self Hosted/On-Prem CWP

from pcpi import session_loader

session_manager = session_loader.load_config_env() #only returns a single session_manager object

from pcpi import session_loader

session_managers = session_loader.load_config_user()
session_manager = session_managers[0]

Session Managers

If you want to take control on how credentials are stored/loaded into your scripts, use the session managers directly and skip the session loader module. Session manager objects directly accept Prisma Cloud credentials into the object constructor.

This still creates the same Prisma Cloud session object that you use for API requests.

EXAMPLES

from pcpi import saas_session_manager
import logging

py_logger = logging.getLogger()
py_logger.setLevel(10)

session_manager = saas_session_manager.SaaSSessionManager(
    tenant_name='My PC Tenant',
    a_key='xxxxxxxxxxxxxxxxxxxxxxxxxx',
    s_key='xxxxxxxxxxxxxxxxxxxxxxxxxx',
    api_url='https://api.prismacloud.io',
    logger=py_logger
)

cspm_session = session_manager.create_cspm_session()
cwp_session = session_manager.create_cwp_session()

from pcpi import onprem_session_manager
import logging

py_logger = logging.getLogger()
py_logger.setLevel(10)

session_manager = onprem_session_manager.CWPSessionManager(
    tenant_name='My PC Tenant',
    uname='xxxxxxxxxxxxxxxxxxxxxxxxxx',
    passwd='xxxxxxxxxxxxxxxxxxxxxxxxxx',
    api_url='https://<yourselfhostedurl>',
    logger=py_logger
)

onprem_cwp_session = session_manager.create_cwp_session()

Requests

The Prisma Cloud Python Integration uses the Python3 Requests library to make API calls. The Prisma Cloud Session object that this tool provides has a wrapper function for API calls using the requests function from Requests. The main difference is that this tool handles the 'headers' section of the request for you. The remaining fields can be used just like you would use the requests library requests.request.

EXAMPLES

from loguru import logger
loguru_logger = logger

from pcpi import session_loader

#Default config file will be created at '~/.prismacloud/credentials.json'
session_managers = session_loader.load_config(logger=loguru_logger)
session_manager = session_managers[0]

cspm_session = session_manager.create_cspm_session()

response = cspm_session.request('GET', '/cloud')
print(response.json())

payload = {
    "accountId":"xxxxx",
    "accountType":"account",
    "enabled":True,
    "externalId":"xxxxxx",
    "groupIds":["xxxxx"],
    "name":"Name",
    "protectionMode":"MONITOR",
    "roleArn":"xxxxxxx",
    "storageScanEnabled":False,
    "vulnerabilityAssessmentEnabled":False
}

query_string = {"skipStatusChecks":1}

response = cspm_session.request('POST', '/cloud/aws', json=payload, params=query_string, verify='path_to_cert.pem')
print(response.status_code)

Logging

Two logging libraries are supported by PCPI. The built in Python logging library (used by default) and Loguru. Loguru is strongly recommended but it is an additional dependency that you may not want.

EXAMPLES

#Minimum setup
from pcpi import session_loader

session_managers = session_loader.load_config()
session_manager = session_managers[0]

cspm_session = session_manager.create_cspm_session()

res = cspm_session.request('GET', '/cloud')
print(res.json())

#Recommended setup
from pcpi import session_loader
import loguru

session_managers = session_loader.load_config(logger=loguru.logger)
session_manager = session_managers[0]
cspm_session = session_manager.create_cspm_session()

res = cspm_session.request('GET', '/cloud')
print(res.json())
