How to use Python tools for cybersecurity

Python is a high-level, interpreted programming language known for its simplicity and readability. You can find a large pool of libraries written in Python due to its portability, fast script creation, versatility, and clean code design principles. 

Automation is one of the biggest advantages that Python cybersecurity tools offer. Python allows developers to focus on complex issues, streamline cybersecurity, and increase overall software security. 

Usually, developers and security specialists integrate Python cybersecurity tools into their products in the form of automated scripts. Python offers a vast number of libraries, packages, and frameworks that contain ready modules. These allow developers to create productive and fast scripts for any existing solution regardless of the core programming language. Automated scripts are the most common way of integrating Python cybersecurity tools into a software product.

If you want to enhance the security of your existing software, you can integrate Python scripts for cybersecurity with one of these techniques:

Ways to enhance your solution security with Python scripts
  • Using interoperability libraries. Python offers various libraries that allow you to call functions or methods from existing software written in another language including C/C++, Java, and .NET. These libraries bridge the gap between languages and frameworks, binding scripts and your software together. For example, Cython allows for communication between Python and C code.
  • Building APIs. Application programming interfaces (APIs) are a universal way to connect two different pieces of software and enable data exchange. To connect Python scripts to your existing software, you can use frameworks like Flask, Django REST, or FastAPI. 
  • Wrapping existing code. This approach entails creating a Python wrapper around your existing code and providing Python with an interface to interact with your software functions. 
  • Using message passing or data exchange. With this method, you create a communication channel between your code and Python scripts. For this, you can use inter-process communication or message queues through libraries like ZeroMQ. This keeps your code clear, modular, and scalable.

Script automation is integrated into most cybersecurity-related Python tools, which allows developers to customize their scripts and use minimal code to create them. 

Although Python has a vast number of libraries and tools, it can be challenging to figure them out on your own. At Apriorit, we constantly use Python for cybersecurity tasks and have a toolkit of time-proven Python libraries, frameworks, packages, and tools. In the next two sections, we share some practice-based recommendations for Python tools that can help boost your product’s cybersecurity. 

We’ve divided cybersecurity activities into two main categories: 

  • Security testing 
  • Security analysis

Both of these activities are essential for maintaining robust security in software products. You can find many effective Python tools that can cover these cybersecurity tasks and help you assess every part of your software. Let’s explore uses for the Python language in cybersecurity and the tools it offers for each task.
