6 Best Cyber Security Programming Languages To Learn in 2024

If you want to be a cyber security professional, then you need to know how to program. Many of the attacks that are launched against systems involve malicious code, so being able to read and code in cyber security programming languages will help you defend your system against these attacks. 

Now, while the usual route of picking up language basics and figuring out the rest later sounds appealing, it won’t work as well as a targeted approach for cyber security.

Several programming languages for cyber security are commonly used, including Java, Python, C++, Assembly, Ruby, and Perl. While these each have their strengths and weaknesses, we recommend starting with Java or Python as your first coding language for cyber security. These are both widely used, versatile, and easy to learn, making them ideal starting points for anyone looking to learn the best programming languages for cyber security.

Best Cyber Security Programming Languages

1. Java

Java is a powerful programming language that’s used for mobile apps, web development, and cyber security to name a few. As an object-oriented language, Java makes it easy to incorporate complex data structures in your code. Java also offers an extensive range of libraries and frameworks that can speed up your development.

With the ability to run on multiple platforms, alongside support for cyber security tools and cyber attack prevention, Java is an excellent choice for cyber security professionals. And being so popular, aspiring Java developers can enjoy access to various online resources and tutorials to learn the language quickly and effectively. If you want to work for an organization that focuses on cyber security, Java is definitely a strong choice.

One of the main benefits of choosing Java for cybersecurity programming is the ability to work with machines securely and efficiently. These robust security features allow you to quickly generate cryptographically secure keys and safely transmit data over networks. 

Java’s cross-platform support also allows you to write code just once, and then speedily deploy it on various devices and operating systems. 

Java's simple syntax also makes it easy to read, understand, and debug, which is particularly useful when dealing with complex cyber attacks.

Tips & Advice on the Best Way To Learn a Cybersecurity Language

The best way to learn a cybersecurity programming language is to explore your options and find one that aligns with your specific interests and goals. If you’re planning to take a computer science major or you’re going to attend a cyber security training institution, you’ll definitely learn a broad range of cyber programming language skills.

But, if you want to teach yourself cyber programming, the best way is to start coding!

The first step is to find yourself a roadmap to guide you as you learn the necessary skills. You can then start by learning Java or Python. Both cyber security coding languages are very popular, and there are many cyber tutorials and other helpful materials available for you to get started.

But ultimately, the best way to learn cyber programming is to dive in and start coding: with patience and persistence, you will gain the knowledge and skills you need to excel in this exciting and dynamic field.

My advice is to focus on your end goal. For example, if you want to be a white hat cyber security analyst, focus on cyber defenses, cyber-attack simulations, cyber vulnerability detection, and cyber defense strategies. For these areas, you need to be proficient in cyber programming languages like Python, Java, Ruby on Rails, and even JavaScript.

On the other hand, if you want to become an ethical hacker or cyber penetration tester, then I’d recommend focusing on cyber attacks and exploits whilst also learning languages like C++ and Assembly. 

Also, if you’d like to become a cyber security engineer or architect, it’s good to focus on cyber attack modeling tools and coding best practices. 

Whatever your goal, choosing a cyber security programming language to learn is just the beginning. You will need to put in the time and effort to truly master cyber programming, but if you do, you’ll be well on your way to becoming an expert cyber security professional.



Cyber security is a rapidly-evolving field that is vitally important to most industries and business sectors. 

It’s therefore not surprising that there is an equally growing demand for cyber security professionals to ensure that systems are safe and secure from cyber attacks. 

If you aspire to be a cyber security professional, then you really need to know how to code with at least one of the many cyber security programming languages.

While there are a range of languages that are well-suited to cyber security, the most commonly used are Java, Python, C++, Assembly, Ruby, and Perl. 

If you’re new to the field, we’d recommend starting with Python or Perl, but if you’re an experienced pro, adding any of these languages to your arsenal can help you raise your performance on your way to advancing your career.
