5 Essential Programming languages for Cybersecurity pros

Cybersecurity experts are in high demand due to rising cybercrime rates worldwide and in this article you will about top five programming languages for cybersecurity. You will need a variety of talents to succeed as a cybersecurity professional, including the ability to confidently recognize possible assaults and develop workable solutions. You must be knowledgeable about numerous programming languages in addition to being up to date with cybersecurity news. To become a top cybersecurity specialist, you must grasp coding since it will enable you to recognize the strategy behind an attack and protect against some of the most dangerous hacking methods.

For additional information, view the online cybersecurity training. The top five programming languages for cyber security are listed below.:

5 Essential Programming languages for Cybersecurity pros
  1. C and C++.

One of the original programming languages is C. Dennis Ritchie created it in the early 1970s. The creation of software such as operating systems, databases, compilers, and other tools is its principal use. For beginners, it is a great language to learn to program with. Also, learning other programming languages like Java and Python will be a lot simpler once you have a basic understanding of C.

Bjarne Stroustrup developed the general-purpose programming language C++. It is a C programming language extension that is mostly used to create operating systems, browsers, games, and other software. Programming styles including procedural, object-oriented, and functional are all supported by C++.

Both are low-level programming languages that you must be familiar with in order to work in cybersecurity. These programming languages for cyber security include low-level access to hardware, including RAM and system processes, which, if unprotected, can be easily used by hackers.

What are the benefits of C and C + + in cybersecurity?

  • For reverse engineering and spotting vulnerabilities, C and C++ can be helpful.
  • The C++ programming language is used to create a large amount of malware. As a result, mastering C++ is crucial for deciphering and comprehending open-source code.
  • C++ is a popular programming language for cybersecurity applications like the network mapper utility Nmap.
  1. Python.

Python is a high-level, object-oriented, general-purpose programming language. Due to its adaptability, it is one of the most well-known and frequently used coding languages.

It is the perfect programming language for creating complicated applications since it has capabilities like high-level data structures, dynamic binding, dynamic typing, and others. Python is appropriate for all-purpose jobs including big data facilitation and data mining. Compared to other low-level languages, it is a high-level scripting language that is simpler to learn.

Because it can carry out a number of cybersecurity tasks like malware analysis, penetration testing, and scanning, Python is a helpful programming language for cybersecurity specialists.

Why is Python Useful in Cybersecurity?

  • Python is simple to learn and use for cybersecurity experts because of its short learning curve.
  • Python enables managers in the field of cybersecurity to accomplish projects swiftly.
  • Since it has a large library, cybersecurity technologies are already available.
  • Many operations, including host discovery, server access, port scanning, and network scanning, can be carried out using Python.
  • It makes it easier for cybersecurity experts to become proficient quickly.
  1. JavaScript. 

The most widely used and well-known programming language is JavaScript. It is the most popular language on the internet. Moreover, the popularity of frameworks like jQuery, Angular, and React JS has increased the use of JavaScript.

It facilitates the development of both front-end and back-end software utilising various Javascript-based frameworks, such as jQuery and Node.JS.


JavaScript offers a wide range of libraries and frameworks, and its use is increasingly widespread in the creation of desktop, mobile, and video game applications.

One of the best programming languages for cyber security that you can learn is this one. If you know JavaScript well, you can ensure that XSS attacks are minimised or completely avoided on the website.

Why is JavaScript Useful in Cybersecurity?

  • It enables you to create secure user interfaces and websites.
  • It reduces other technical hazards and possible cross-site scripting attacks in web forms.
  • You can use cross-site scripting, event handler manipulation, and cookies with JavaScript (XSS).
  • When it comes to weakening a website, XSS is a common hacking method. The hacker utilises programs to take control of the website if it has an input bug.
  1. PHP.

Websites are created using the server-side programming language PHP. PHP is the server-side language that runs 80% of the top 10 million websites on the internet. So, having an understanding of PHP will help you to be able to fight against invaders.

DoS (Denial of Service) attacks are one of the hacking methods that PHP is used for most frequently. By taking down the website, such assaults typically aim to render web applications inaccessible to users.

If you are not careful with how you have built your website, hackers may even use PHP to wipe all the data on it. You can therefore find and fix these vulnerabilities in PHP code by studying the PHP programming language.

Why is PHP Useful in Cybersecurity?

  • It enables cybersecurity experts to put effective solutions to protect online applications into practice.
  • Using PHP and cybersecurity solutions together helps reduce the impact of regular cyberattacks.
  1. SQL.

Programmers use the domain-specific language SQL (Structured Query Language). It controls the databases’ data management. SQL is the most sought-after computer language for handling databases as businesses become more data-driven.

Users of SQL can access records or data in groups with simply one command. Consequently, the user won’t need to describe how the data should be retrieved by using SQL queries.

Nowadays, the majority of hackers attempt to use databases to their advantage in order to steal or manipulate data. The password that is kept in the database is brought up and compared with what you have entered into the system whenever you try to log in to a website.

While you cannot see it, hackers exploit this by using SQL injection to steal sensitive information from businesses and people. Important data, including passwords, bank account information, and social security numbers, may be lost as a result. Thus, mastering SQL can assist you in securing databases.


Knowing programming languages for cyber security will not only enhance your resume but will also put you ahead of the competition.While many entry-level cyber security occupations don’t require programming knowledge, some mid-level and upper-level cybersecurity roles do demand it. Additionally, you may be able to develop in your profession and move towards long-term success in the area if you have some familiarity with at least one programming language. Online cyber security courses can teach you more.
