Python for Cyber Security: A Complete Guide For Beginners

The importance of Cybersecurity is increasing as businesses go digital. Confidential information is mostly at risk. Employing Cyber Security professionals who can spot and address these risks is now a top priority for businesses. Concerns about Cyber Security are real and need to be addressed right away.  

Along with the latest developments in the field of Cybersecurity, you should be familiar with different programming languages to recognise the strategy behind an attack. Among numerous programming languages, Python has proved to be one of the best for Cyber Security. 

According to Statista, Python has emerged as one of the most extensively used programming languages in the last ten years. Despite its release in 2008, Python 3 took some time to gain popularity, and now it has a 95% market share.  

Python is a valuable Cyber Security language since it can handle a wide range of tasks. It holds everything, including analysis and testing. Python provides the strength, capability, and flexibility to defend against cyberattacks and protect corporate systems. 

This blog will highlight the importance of Python for Cyber Security, why we need Python in Cyber Security, the benefits of Python programming, and much more. Read on to learn more.

Python for Cyber Security

Python is an interpreted, high-level, object-oriented programming language. Between 1985 and 1990, Guido van Rossum designed it.   

Python is a free and open-source programming language that may be used to create software and websites and automate operations. Because it may be applied to numerous application fields, it is referred to as a general-purpose programming language. Its versatility and ease of usage makes it suitable for beginners.  

Python is helpful, especially for students and working professionals, to become software engineers. Nowadays, Python is a language that can be applied to most fields. Python is an interpreted language; therefore, compilation before running is unnecessary and can be run immediately. It can be utilised as a scripting language as well. Also, it has automatic garbage pickup. Let’s have a look at some useful features of Python: 

a) Learning Python is simple. 

b) It uses a participatory mode. 

c) It is portable and can be used with a variety of hardware. 

d) Python allows for development Graphical User Interface (GUI) applications that can run on several Windows-based platforms. 

e) Python can be used for different purposes in Cyber Security, such as creating tools and scripts. 

Why is Python used in Cyber Security?

Python makes it easier for Penetration Testers and Cyber Security researchers to analyse malware, cyber threats, scanning and to automate processes. It is frequently used by Cyber Security experts because- 

1) Python is simple to use and learn

Python is a small programming language that doesn't need a lot of complicated codes. Python is straightforward, which makes it far simpler to learn than other programming languages like C, Java, etc.   

2) Python is a free software program

Python is an open-source programming language which allows programmers to contribute to their open-source platform, just like Linux. Python can be used for free and has a strong development community that constantly works to improve it.  

3) Python scripts can be written rapidly

The most significant advantage for Cyber Security experts is that Python greatly simplifies scripting. Quite a few applications only have basic backend coding. But Python has an edge in that after a cyberattack or during security testing; it takes less time to repair or fix. 

4) Automatic Memory Management

There is a memory management system integrated into Python. Developers will benefit significantly from this as they need not worry much about memory management.  

5) Vast libraries

Python consists of many libraries and frameworks that are helpful for a Cyber Security professional. It also helps in Pen Testing. These libraries are more beneficial than other languages like C, Java, etc.

Understanding the benefits of Python Programming 

There are a lot of benefits of Python Programming. Python programming is useful for Cyber Security professionals as it can perform a wide range of Cyber Security functions, including malware analysis, scanning, and penetration testing tasks. Let's discuss the specific advantages of Python, what makes it so beneficial for Cyber Security, and why you should take the time to learn the Python programming language: 

1) Productivity

Python is widely regarded as the most productive programming language. Developers may concentrate on the primary goal of the project or the issue during any vulnerability assessment because of its simplicity. Additionally, it optimises memory allocation as it requires a few lines of code to construct and run the Python application.  

2) Translated language

Python is also well-known for being an interpreted language. Interpreted indicates that compilation is not necessary before running the program. Line by line, the code is directly executed. 

3) Flexibility

Contrary to C/C++, it is portable across a variety of operating systems; thus, we do not need to rewrite the code for a different platform. As a result, it will be advantageous because you would not have to write the script or code repeatedly, saving time and effort.  

4) Streamlines troubleshooting

Python is a straightforward programming language with an English-like syntax. It makes reading the code and solving issues easier. It speeds up the process of finding and fixing bugs in the code. Cyber Security experts can utilise Python to diagnose any harmful code used by online attackers quickly. 

5) Strongly typed

It is a strongly typed language, so you don't have to worry about declaring the data type of a variable every time; it will do that for you based on the variable's value as it is executed. 

6) Understanding Python programming is easy

Python is a high-level programming language with a typical and simple structure, similar to English, making learning, writing, and understanding the code simple. Compared to other programming languages like C/C++, Java, etc., with Python, you can write any program in a few lines.

How is Python used by Cyber Security Analysts?

The network and infrastructure of the IT firm are built and secured by professionals known as Cyber Security Analysts. Python is used by Cyber Security Analysts to implement big check-ups using automated scripts that can be made in Python. Additionally, it has automated tools that users can modify to meet their needs.  

It can be used to generate automated responses in response to user input, but one must set it according to their needs for that as well. Many libraries enable professionals, including Cyber Security Analysts, to develop effective programming with few lines of code. Let us now take a look at a few of the Python libraries which can be used by professionals in Cyber Security to write their automation code to prevent errors. 

Few Important Python Libraries for Cyber Security

Python libraries are extensive. Let us talk about a few important Python libraries used by professionals in Cyber Security: 

1) Network Security libraries - Tools like NMAP (Network Mapper) and twisted are frequently used for network layer scanning, port identification, and the identification of various application protocols. 

2) Beautiful Soup - It is used to gather scrap data from websites in the form of XML (Extensible Markup Language) and HTML (Hyper Text Markup Language). 

3) YARA - It is used in identifying and classifying malware. 

4) Mechanize - It is utilised for data interaction. It is also applied in XSS (Cross Side Scripting) and SQL Injection. It can be used to capture website data. 

5) Pymetasploit3  - You can use this library's Metasploit framework to find various bugs on various environments or platforms, such as for mobile, Linux, or Windows exploitation. Metasploit contains a large number of payloads. 

6) Scapy - It is utilised for packet processing on any network, including decoding and analysing packets (a small segment of a larger message). 

7) Library for Cryptography - Cryptography libraries are used to secure or encrypt any file with cryptographic techniques. 

8) Psscan - It is used to display terminated processes, i.e., those that have already been terminated. Finding the previous procedure makes uncovering certain details about the attacker easier. 

Conclusion 

Python is and will continue to be the most demanding scripting and programming language for Cyber Security. Some job roles and career paths in the IT or Cyber Security fields will be open to you if you develop mastery of Python.
