Online Internet Security Classes – You may think of Python as a data science programming language, but did you know that cybersecurity engineers rely heavily on Python? From penetration testing to automating security processes, Python has become an in-demand skill for today’s cybersecurity professionals, and Flatiron School Cybersecurity Instructor Aastha Sahni joins us to explain how Python is used at work. Find out which Python libraries and frameworks are most popular among cybersecurity professionals and how to learn Python for cybersecurity at a boot camp like Flatiron School!
Python is a free, open source programming language with a strong focus on code readability and indentation. Python is accessible and modifiable, and can be used to design and customize web applications, scientific computing, artificial intelligence, and data science. It’s Python

Language, so when you run Python code, it is automatically converted to machine language. This is unlike other languages such as C++ which must first be compiled and then interpreted.

Python is easy to learn, code, run, and read, making it a highly sought-after skill. All this makes Python the easiest and most used programming language in technology, including cyber security!
A cybersecurity analyst uses Python scripts to automate tasks such as performing penetration testing. A large number of cybersecurity applications and tools are based on and rely heavily on Python, meaning they can be tailored to individual needs and requirements.
To know Python and there are so many areas in cybernetics that don’t involve using Python every day. However, it is always useful to know the basics of Python. The biggest advantage of knowing Python for cybersecurity is the ability to write scripts. Writing and developing scripts becomes very easy as it supports minimal code and extensive use of libraries.
Cybersecurity engineers are more involved in development, architecture, and customization, which involves understanding complex data structures, and may require an intermediate level understanding of Python. If you want to be a security engineer where you are building a custom tool or application, you need to know Python at an intermediate level.

A basic knowledge of Python opens many career doors for a variety of roles, not only in cybersecurity, but also in other fields such as data science. Beyond the basics, knowing Python at an intermediate level will definitely help a cybersecurity professional in interviews, increased responsibility, and future opportunities.
Python is popular because it is free, simple, and requires minimal coding, thanks to the functions and methods of the Python libraries. And the Python libraries are extensive! Python libraries are used to implement various functions and capabilities in the field of cybersecurity. Here are some of the main libraries that cyber security professionals use for multiple operations in the workplace.
The Python libraries most commonly used for natural language processing, data analysis, visualization, and more are NLTK, NumPy, and Pandas. These libraries are also used for malware analysis.
The Scikit library is widely used to implement machine learning in cyber security operations. Machine learning algorithms are also supported by Scikit.

Network security related libraries such as Nmap and Twisted are often used to scan and implement transport layer, application layer protocols.
Scapy is used to process packets, decode packets, spoof packets, and analyze packet information on a network.
Beautiful Soup is often used to scrape data from web pages in HTML and XML format.
The Cryptography Library is used to implement cryptographic algorithms, specifically to secure something like a file, communication, etc.

Mechanize (which is similar to Beautiful Soup) is used to extract data and interact with and extract data from web pages. Mechanize is also used to check for SQL injection and cross-site scripting.
Penetration testing, also known as pen testing, is a broad area of practice where cybersecurity professionals attempt to assess
Organization security. This way, cyber security professionals can notify the company of any major gaps in their security and are then better prepared for cyber attacks.
Someone doing a pen test is doing everything an attacker would do. There are seven levels of penetration testing, and at each level, except for the first pre-engagement level, different Python libraries can be used:

There are a few Python libraries and frameworks that cyber security professionals rely on when under cyber attack:
Cyber security professionals also rely on automating security tasks when under cyber attack. SOAR (Security Orchestration, Automation, and Response) helps automate security tasks and is often used during incident response when analyzing various alerts.
Using Python, cybersecurity professionals can also create playbooks that can automate analysis, from analysis to generating a ticket for an incident response analyst.
The Flatiron School teaches Python in the Cybersecurity Engineering Bootcamp. In the bootcamp, there are laboratories dedicated to Python, where students get practical experience in solving tasks. We use Python in developing various scripts and pulling for cryptographic algorithms. Cybersecurity engineering bootcamp students also use Python in other courses such as cryptography. Not only do students at Flatiron School learn Python, they also learn how it is used practically in cybersecurity.

Training Troubleshooting Guide
When a large company with poor security experiences a data breach that exposes your personal information, password information, or profile pictures, there’s nothing you can do about it. But that doesn’t mean you’re powerless to protect yourself. Focus your energy on protecting your home security and privacy. You don’t want to lose the novel you’re writing to ransomware or let a banking trojan gobble up all your money, do you? Fortunately, you can set up local defenses for these local problems.
It really doesn’t take much effort to make your devices, online identity and activities more secure. In fact, several of our tips on what you can do to be more secure online boil down to common sense. These tips for making your online life more secure will help you stay safer.
We call this type of software antivirus software, but defending against actual computer viruses is only a small part of what they do. Ransomware encrypts your files and demands payment to recover them. Trojan horse programs appear to be legitimate programs, but they steal your private information behind the scenes. Bots turn your computer into a soldier in an army of zombies, ready to attack with a denial of service, spam, or whatever else the bot herder commands. An effective antivirus program protects against these and many other types of malware.
In theory, you can set and forget your antivirus, let it hum in the background, download updates, etc. In practice, you should review it every now and then. Most antivirus utilities display a green banner or icon when everything is fine. If you open the widget and see yellow or red, follow the instructions to get things back on track.

You might be thinking, wait, isn’t an antivirus built into Windows? Not only is Microsoft Defender built into the operating system, it automatically takes over protection when no other antivirus detects it, and it also automatically steps down when you install third-party protection. The thing is, this built-in antivirus simply cannot compare to the best third-party solutions. Even the best free ones are much better than Microsoft Defender. Don’t rely on it; you can do better.

Whether you’ve chosen a simple antivirus or a full security suite, you’ll need to renew it every year. It’s best to sign up for auto-renewal. For some security products, this allows for a malware-free guarantee. You can always unsubscribe later if you want to switch to another product.
One more thing. If your antivirus or security suite doesn’t have ransomware protection, consider adding a separate layer of protection. Many ransomware-specific utilities are completely free, so there’s no reason not to try a few out and pick the one that works best for you.
