Now that we’ve established that Python is a go-to language in cybersecurity, let’s talk about the specific benefits of Python, what makes it so useful for cybersecurity, and why you should take the time to learn the Python programming language.

The Benefits of Python

The design and functionality of the Python programming language give it many benefits that have made it a go-to programming language for a lot of fields, such as data science, mathematical computation, web development, and of course, cybersecurity.  Let’s take a look at the benefits of Python now.

Python is easy to learn and implement.  

Python was intentionally designed to be a straightforward, easy, and generally lightweight programming language that would require minimal code to accomplish tasks compared to other languages.  The fact is that Python often takes substantially less code than what would otherwise be required of other programming languages, such as C or Java. The nature of Python’s straightforward structure means a shorter learning curve for anyone working with the language, especially those new to programming.

Python makes debugging easier.  

We’ve covered the fact that the structure of Python makes it easier to learn and implement, but that basic nature has other benefits as well.  The straightforward design of Python and ease of use also increases its readability, Increased readability also makes debugging code far more straightforward, which means that even lower level or beginner programmers can troubleshoot and debug their own code pretty effectively and that debugging can take much less time overall to complete.

Python is open source.  

Python was developed as an open-source programming language, similar to how Linux is an open-source operating system.  The open-source nature of Python lends itself to a strong community of developers that support the language and move it forward.  Since python is open source, there is a great deal of information available, and using the language is free.

Automatic memory management.  

Another benefit of Python that some people don’t consider is that it has memory management built-in automatically by design.  Python’s memory management is performed internally by the Python memory manager. This means that the programmer and the user need to have less concern about memory management, including factors as caching, memory allocation, and segmentation.

Python’s Usefulness in Cybersecurity

We’ve discussed above the benefits of the Python programming language, and that it’s used in many fields.  Let’s now take a deeper look at why Python is so useful for the field of cybersecurity.

Cybersecurity professionals can get up to speed quickly.  

Because Python has a generally short learning curve, it has become the programming language of preference for those in the cybersecurity field, many of whom have a limited programming background.  Python ease of use means that any experienced cybersecurity professional that has built up a relatively strong technical background can learn the basics of the Python language and start programming and implementing their code quickly.

Cybersecurity teams can form quickly.  

Another benefit of Python’s ease of use and short learning curve means that not only can cybersecurity professionals get up to speed quickly on the programming language, but that cybersecurity teams can also form quickly to work on a project, even if all of the members of the team do not have a coding background.  Consider how much more limited a cybersecurity team would be if they had to rely on the group understanding a more difficult language, like Java. The flexibility and ease of use of Python end up being a great benefit for cybersecurity managers that need to lead teams and Implement projects quickly.

Python’s extensive library means cybersecurity tools are already available.  

As we’ve described above, Python’s ease of use is certainly one of the most important factors that make it a go-to language for cybersecurity professionals.  But certainly, Python’s extensive library of modules is a leading factor as well. Python has become well known and heavily used, because of its extensive library, which means cybersecurity professionals don’t need to reinvent the wheel with common tasks and in most cases can quickly find cybersecurity analysis or penetration testing tool already available.

Python can be used for nearly anything in cybersecurity.  

With a strong understanding of Python and programming concepts in general, cybersecurity professionals can accomplish just about any task that they need using Python code.  For example, Python is used heavily in malware analysis, host discovery, the sending and decoding of packets, accessing servers, port scanning, and network scanning, just to name a few.  Considering also that Python is so effective at scripting, automating tasks, and data analysis, it is understandable that Python has risen in popularity as cybersecurity has become more important.

Scripts in Python can be developed quickly

Another benefit of Python that helps cybersecurity professionals is that the ease of the code means that cyber pros can develop solutions that they need with a minimal amount of time, and with rather simplistic code.  This means that errors in code are easier to find and correct and that cybersecurity professionals can solve problems and challenges quickly.

Why You Should Learn Python

Python is a great first language to learn.  

Python serves well as a gateway language that can help you learn other object-oriented languages later on, and can even help you learn languages that technically aren’t object-oriented.  Since Python has such an easy learning curve and is so debugger friendly, it is a great first step before you move on to Java, C, PHP, or any other language that is commonly used.

Plenty of free learning resources.  

The Internet has a lot of free Python resources available, including videos and sample projects.  Given the massive amount of material available online for free, just about anyone can gain a working knowledge Python without taking a class.

Python is impressive to employers.  

Employers value and respect just about any well-known programming language that you can include on your resume, but Python seems to hold a special place in employers’ minds, perhaps because fewer people know the language, and because of the flood of Python use in recent years.  Several recent studies have even listed Python as the number one in-demand technical skill sought by employers.

Final Thoughts

If you’re interested in learning Python in order to get into cybersecurity, keep in mind that your Python knowledge is only as useful as your cybersecurity knowledge in general.  In other words, a Python expert that has no understanding of systems security and penetration testing tools will be unable to put that Python knowledge to use, as it relates to cybersecurity.  Being a solid cybersecurity professional that can use Python to your advantage means that you need to be well rounded in your knowledge and ability. Always strive to broaden your cybersecurity knowledge.
