As companies advance digitally, cybersecurity becomes a priority. Hackers regularly present risks to confidential information. Companies now focus on hiring cybersecurity experts who can identify and tackle these vulnerabilities. Cybersecurity concerns are valid and require immediate attention.
Programming and cybersecurity go hand-in-hand. As one of the top programming languages for cybersecurity, Python plays a crucial role in 2021. It is a counter-force for malicious codes and programs that attackers use to penetrate the system.
Python is a useful cybersecurity language because it can perform a multitude of operations, from analysis to testing. Many people term it as the best programming language for cybersecurity 2021. Python has the power, extensibility, and functionality to prevent cybersecurity attacks and keep organizational systems safe.
This article will highlight the various applications of Python as a cybersecurity language. We will showcase how cybersecurity teams can use the programming language and protect their confidential data.
Benefits of Python for Cybersecurity
Python’s companion, data science, is a major field of study that contributes to cybersecurity. The benefits of Python in data science include fraud detection, automation, and system monitoring – among many others. These use cases are directly related to data security and can be easily implemented by cybersecurity professionals.
Apart from that, Python is one of the best programming languages for cybersecurity due to the following reasons:
- Simplifies Debugging
Python is a simple programming language with syntax similar to English. It simplifies reading the code and troubleshooting problems. It reduces the time taken to debug the code and identify errors in it. The built-in troubleshooter, PDB, is a significant tool that can easily debug the code. If there’s any malicious code that cyber attackers use, cybersecurity professionals can use Python and debug it easily.
- Useful in Automation
Cybersecurity Python scripts are highly useful in the automation of several tasks. They help to perform operations like regular system monitoring, service authorization, firewall rules, and more. Cybersecurity teams can save a lot of time as they can focus on data protection, get ready for any threats that the automation tools identify, and prepare a plan for eliminating them.
- Easy Implementation
Python is one of the easiest programming languages for cybersecurity. It is a beginner-friendly cybersecurity language that any developer can easily master. They can use minimal code to perform powerful functions. It has a shorter learning curve, along with simpler implementation. Even those new to programming can learn Python and understand how it is useful in scripting for cybersecurity.
- Memory Management
Python offers automatic memory management by design. The Python memory manager externally executes the memory management. Developers don’t have to worry about memory allocation, caching, and partitioning while working with cybersecurity. It reduces the concerns about memory when cybersecurity experts explore data for any weaknesses and vulnerabilities.
- Extensive Libraries
Python provides a vast library for various cybersecurity operations. Developers don’t need to reinvent the wheel or write the code from scratch. There are libraries for cybersecurity analysis, penetration testing, threat detection, and more. They simplify the process of creating cybersecurity applications for identifying vulnerabilities and fixing them as they arise.
Python’s Uses as a Cybersecurity Language
Now that we understand the benefits of Python for cybersecurity, let's look at the various areas where cybersecurity teams can use Python in cybersecurity implementation. Cybersecurity Python scripts are easy to write and understand, making it the perfect choice of programming language.
Here are the uses of Python in Cybersecurity as a language:
- Data Extraction
Python provides valuable uses in extracting data from social media platforms like Whatsapp or Facebook. It also helps in parsing data from pdf files and websites to better understand security vulnerabilities.
- Geolocation Extraction
One of the most important use cases of Python in cybersecurity is geolocation extraction. Python, Google APIs, and pygeoip modules are useful to track the real-time location of an IP address and understand where the attack came from.
- Packet Sniffing
Python’s socket module is useful in building a packet sniffer. The raw socket provides quick access to the protocol. It uses binary form to send and receive data, easily understandable by Python.
- Better Script Development
Cybersecurity Python scripts are easy to develop and implement. The simple code allows cybersecurity experts to write programs swiftly and solve problems in less time than other programming languages.
- Network Port Scanning
Python socket programming is useful in implementing the Nmap tool. Many of the digital forensics tools in Linux can easily operate using Python’s simple code. Only a few lines of instruction are enough for socket programming.
- Complete CyberSecurity Package
Python is a complete package for cybersecurity applications. It enables developers to do anything related to cybersecurity – from threat detection to system fixes. It offers packet encoding and decoding, malware analysis, network scanning, and more.
Python is one of the extremely useful programming languages for cybersecurity. As a modern-day language, it is helpful for keeping organizations digitally advanced and has what cybersecurity professionals need to safeguard against vulnerabilities and cyber threats.
