pypanther

pypanther is a Python library for building Panther analysis content for the Panther cybersecurity product. It provides a simple and intuitive interface for creating, managing, and deploying detections to enhance your security posture. Included is a pypanther CLI tool to interact with your content and upload it to the Panther web app.

Features

• Rule Creation: Easily create rules using Python classes and inheritance.
• Management: Organize and manage rules efficiently with native Python.
• Deployment: Upload detections and more to Panther for real-time detection.

Installation

To install pypanther, use pip:

pip install pypanther

Prerequisites

• Python 3.11 or higher
• Panther account and API access

Usage

1. Import pypanther: Start by importing pypanther into your Python script.
2. Create Rules: Subclass the Rule class to define new rules.
3. Register Rules: Register your custom rules and Panther managed rules inside your main.py file.
4. Test Rules: Test all your registered rules using pypanther test.
5. Upload Rules: Upload all registered rules with your Panther deployment using the CLI tool (pypanther upload).

Getting Started

Here is a simple example to get you started:

from pypanther import Rule, register, LogType, Severity


# Create a new rule
class MyRule(Rule):
    id = "MyRule"
    default_severity = Severity.HIGH
    log_types = [LogType.OKTA_SYSTEM_LOG]

    def rule(self, event):
        return event.get("status") == "breached"


# register the rule
register(MyRule)

Local Development

We use Poetry for dependency management and packaging. Poetry makes it easy to set up a consistent and isolated development environment.

Setting Up for Local Development

1. Install Poetry: Follow the instructions on the Poetry website to install Poetry.

2. Clone the repository: Clone the pypanther repository to your local machine.

   git clone [e-mail]:panther-labs/pypanther.git
   cd pypanther
   

3. Install dependencies: Use Poetry to install the project's dependencies.

   poetry install
   

   This will create a virtual environment and install all necessary dependencies specified in the pyproject.toml file.

4. Activate the virtual environment: You can activate the virtual environment created by Poetry using:

   poetry shell
   

5. Testing Locally: You can create a main.py file within the pypanther directory to test commands and functionality locally. This file can be used to run test commands or interact with pypanther features.

   • Create a main.py file: Here is an example main file. Assumes you have a folder called custom_rules with all your test rules.

     # pypanther/main.py
     
     from pypanther import register, get_panther_rules, get_rules
     import custom_rules
     
     
     register(get_panther_rules())
     register(get_rules(custom_rules))
     

   • Running the CLI: Use the following command to run main.py with Poetry:

     poetry run python ./pypanther/main.py <cmd>
     

     Replace <cmd> with any specific commands you want to test (e.g. test and upload)

6. Adding Dependencies: If you need to add new dependencies, use the following command:

   poetry add <package-name>
   

   This will update the pyproject.toml file with the new dependency.
