Knowledge of programming languages and coding is a must for cybersecurity professionals. Among the programming languages available, several stand out when it comes to cybersecurity. cites JavaScript, Java, Python, and C# as among the top programming languages recruiters and employers look for. Use this article to discover what programming languages are, how they work, and how they can help you get a cybersecurity job.

The Difference Between Programming and Coding

Simply put, coding is one part of programming. Coding involves using programming languages to tell machines what to do, while programming requires a larger pool of knowledge and experience.

Programmers create and develop programs that serve specific purposes. They assess a program's overall function and use frameworks, testing, and code to bring it to fruition. Coding is one essential part of a larger programming project.

How Programming Languages Are Used in Cybersecurity

Hackers create cyberthreats using programming languages. When cybersecurity experts combat those threats, they also use programming languages.

Cybersecurity is part of programming activities like penetration testing and malware analysis. When used to perform cybersecurity functions, programming languages protect computer systems and programs.

Best Programming Languages for Cybersecurity Experts

To protect computers, programs, systems, and networks, cybersecurity professionals need to know the most widespread programming languages. The programming languages below are some of the most useful and in-demand languages in the cybersecurity field.


A general-use object-oriented language, Python is one of the most popular programming languages. Developers, software engineers, and programmers use Python across diverse industries. It finds use in web development, scientific and numbering computing, and business applications.

Notable companies that use Python include Google, Facebook, Netflix, and Dropbox.

Easy to learn and read, Python can help experts analyze cyberthreats. Hackers often use Python, making it a programming language cybersecurity professionals often encounter.


JavaScript is one of the core scripting languages for web development. Front-end developers use JavaScript, and back-end developers use it through Node.JS.

Object-oriented and event-driven, JavaScript enhances HTML webpages and existing online content. Paypal, Uber, and Microsoft all use JavaScript.

JavaScript plays a role in web applications and game development. Its pervasiveness on the internet makes it a key target for exploitation. Knowledge of JavaScript allows cybersecurity professionals to investigate, protect, and resolve security issues associated with applications that use the language.


Widely used for web-based and enterprise-level application development, Java is the core programming language for Android applications. Java also has applicability in finance, retail, and communications.

Many users find Java more difficult to learn than languages like Python. However, its understandable syntax and rules make it popular for developers. Often considered one of the safest programming languages, Java still has vulnerabilities that hackers can exploit.


Structured Query Language, or SQL, is a domain-specific programming language. SQL communicates with databases and serves as the standard language for relational database management systems in the United States and around the world.

Large enterprises use SQL to maintain, access, and manipulate data. Hackers can attack any database that uses SQL using an injection attack. SQL's widespread use makes it an essential programming language for cybersecurity professionals.

C and C++

The main difference between C and C++ is the latter's function as a procedural and object-oriented programming language. In contrast, C is a procedural language only. Knowing C can make learning C++ easier. Users often consider C++ a more powerful language.

C and C++ use similar syntax, structure, and keywords, many of which perform the same functions in both languages. Web developers and software engineers use C and C++. C++ finds common use in streaming applications like Spotify and YouTube, along with graphics programs like Adobe Photoshop and Illustrator.

C++ can help identify vulnerabilities in software and analyze malware.


As a general-purpose scripting language, PHP makes the internet more dynamic and interactive. Its back-end capabilities make it a common language that companies like Facebook, Slack, and Etsy use. Part of more than 80% of the top 10 million web domains, this powerful language may attract cyberthreats and attacks.

PHP lets software developers integrate logic into a website and manage data. Its extensions interact with databases to extract and store information entered into websites. Because PHP programs involve information exchange, making PHP safe is a necessity when using the programming language.


A crucial web development language, HTML displays information in web browsers. HTML lacks programming logic, but its fundamental importance to creating, organizing, and maintaining websites makes it a language cybersecurity professionals need to know.

Arguably, hacking or accessing HTML code is not illegal. Still, to keep information secure, anyone who wants to keep their website contents safe should understand its vulnerabilities. Knowledge of how HTML can be used to hack is also essential in cybersecurity.

Which Cybersecurity Programming Language Should You Learn?

The right programming language for cybersecurity jobs depends on your interests, position, and industry. Learning several languages can benefit people entering the cybersecurity field. It can also help current cybersecurity professionals advance their careers.

Research can help you decide which language or languages fit your needs. Resources for learning cybersecurity programming languages include free online courses and traditional degrees. Cybersecurity bootcamps and programming language certifications provide options to learn and hone coding and programming skills.
