3. C++

C++ is a powerful programming language that is frequently used in cyber security. It offers developers a wide range of features and options, which can be useful for creating secure applications and systems.

C++ is also considered to be a difficult language to learn, which means there are fewer developers competing for jobs.

So, you must be whispering this to yourself, “Why C++?”

Cybersecurity is one of the most in-demand and rapidly growing industries nowadays.

There are a huge number of cyber security experts around the planet, however, due to its high demand, it’s very hard to find people with enough knowledge and experience for this niche.

Another thing about these experts is that they need to be well versed both in hardware (how different components such as cameras/microphones work) and software (operating systems like Windows, Unix, etc. how they interact with each other).

Because of that, there are not too many people who can be considered an expert in this field – but if you want to become one, then the programming language C++ will definitely help you!

This language has been used for decades in various industries and is known for its powerful features and ability to create robust applications.

So if you want to make a career in cyber security, learning C++ is definitely the way to go!

Not only will it help you understand how different software and hardware work together, but you’ll also be able to write your own code to protect your systems from possible attacks. Good luck!

As cybersecurity becomes more important, the language of C++ becomes more essential.

With over 30 years of development experience, this language has been used in various types of systems. As hardware and software become more complex, so must the language we use to interact with them. Learning C++ can help individuals

4. C#

C# is a general-purpose programming language that can be used to develop many different types of applications and systems. It is an effective option for security-related applications and systems that require reliable performance and high security.

There are fewer developers using this language than other, more popular options, which can make it easier to find work in the field. C# is also somewhat easy to learn, making it a good choice for beginners.

Reason for considering C#? Well, there are quite a few:

C# is one of the most popular programming languages. Why? You can find many different tools and frameworks which you can use to speed up your work.

As a C# developer, if you are not familiar with the “C” language, I would recommend you to start with the “C” language and then move further.

The good thing about learning C# is that it will help you understand how Windows applications work at a low level.

If someone ever asked me what should people learn if they want to be a Cyber Security specialist I always say: “Learn C/C++ first “.

This doesn’t mean that other languages are not important, however, if you have no idea how memory allocation works in C/C++, it is very hard for you to understand how bad guys can overwrite memory and bypass application security mechanisms.

A list of C# programming books that we would recommend for cyber security enthusiasts :

  • The art of exploitation,
  • Advanced .NET decompilation,
  • Windows via C/C++,
  • Malware analyst’s cookbook

“Malware analysis is a rewarding specialization in the computer sciences” ~Kafeine.

Some old articles about malware analysis in C#:

– Unpacking PE files in memory – Part 1 ( last update 07/03/09) by DiRtY_HaCkeR @ Virus Bulletin 2009

– Unpacking PE Files with NPack by Nir Valtman – NirSoft 2008

– Dynamically unpacking malicious executables by Didier Stevens – February 2007

If you want to be a malware analyst, learning C# is a very good idea. With the right tools and books, you can start analyzing malicious executables and understand how they work.

As with any other programming language, it takes time and practice to become proficient in C#.

However, if you are determined to learn this powerful language, you will eventually be able to write code that can help you protect your computer from malware infections.

C# is a great language for cyber security enthusiasts because it helps them understand how Windows applications work at a low level.

It also teaches them how to analyze malicious executables and protect their systems from malware
