What Are Programming Languages?

Programming languages are essentially languages used to communicate with and give instructions to a computer or piece of software. They assist with anything, including network programming, backend development, and application security. Additionally, because of the many reasons cyber experts use these languages, many modern languages are also general-purpose.

What Programming Languages Are Used in Cyber Security?

In cyber security, experts make use of a wide range of languages. For example, a general-purpose language like Python performs penetration testing and malware analysis tasks. Cyber security experts must have programming knowledge to create robust solutions for security vulnerabilities and carry out various cyber security tasks.

Best Programming Languages to Learn for Cyber Security

  • Python
  • SQL
  • C and C++
  • JavaScript
  • PHP

Which Programming Language Is Best for Cyber Security?


Python is a general-purpose, server-side scripting language and one of the most popular languages today. Many experts in the digital world turn to it because of its readability, ease of use, and versatility. From script kiddies to security analysts, people use Python for a wide range of tasks.

This high-level language is also one of the best languages for cyber security professionals. It helps cyber security experts automate tasks and analyze cyber threats. It’s also easy to learn. Hackers also favor Python, so learning the language will also prove helpful for a security analyst to analyze the movements of attackers.


SQL, or Structured Query Language, is a programming language primarily used for communicating with relational databases. It is used by large enterprises worldwide making it a popular language for maintaining, retrieving, and manipulating data.

SQL is an essential programming language in the cyber security field. It’s a powerful language, and hackers can run an SQL injection attack on any database running on SQL. Cyber security experts can ensure they have a defense against threats, like SQL injection attacks, by learning SQL.

C and C++

C and C++ are the best low-level languages in the technology field. These languages enable users to have direct access to various critical components in computers. These components include RAM and system processes. These components are also popular targets for hackers, making C and C++ essential to a cyber security career.

Penetration testers and security analysts use C and C++ to find security issues like reverse engineering, exposing vulnerabilities, and finding programming errors. Through these two languages, experts in the cyber security space can effectively cover all holes in the system that hackers can attack through.


JavaScript is a high-level programming language and the most used worldwide. It can be used by a front-end developer for a website’s user-facing interface while also being used for backend development through NodeJS. JavaScript is the prime coding language of the Internet world.

Since every corner of the Internet uses this general-purpose programming language, the web is a prime target for hackers. Common JavaScript attacks include capturing cookies, exploiting event handlers, and cross-site scripting. A broad understanding of JavaScript allows cyber security experts to defend against and prevent these various attacks.


PHP is a server-side programming language and one of the most popular programming languages for web development, alongside JavaScript. While JavaScript is used for both front end and backend web development, PHP is still the preferred language for the backend. Most top web domains use PHP because of this.

PHP is often a popular target for attacks, such as DDoS attacks. Using older PHP versions, which is not an uncommon mistake, can also lead to potential vulnerabilities in PHP code. If cyber security experts are well versed in this language, they can identify all vulnerabilities, prevent attacks, and defend the server-side of many websites.

Which Programming Language Should I Learn First?

Python is one of the best programming languages for cyber security, whether you are a Python beginner or expert. It’s easy to read, understand, and implement. Despite its ease of use, it’s incredibly versatile and usable for many tasks, such as port scanning and network scanning.

If this programming language is part of your cyber security resume, it will make you an attractive candidate for cyber security roles. Besides that, it’s also a beneficial way to begin learning coding skills. It keeps the journey enjoyable while acquiring a valuable skill.

Is It Possible to Choose the ‘Wrong’ Programming Language?

All programming languages are usable, so there aren’t really wrong programming languages. In addition, having even a basic understanding of a programming language is quite valuable to your cyber security career, regardless of which language you choose.

How to Learn Cyber Security?
