Python is a popular programming language founded by Guido van Rossum and published in 1991. Applications of this programming language include web development, software development, mathematics and related applications, and system programming.

Python is compatible with different operating systems and works. How to write its code is like writing in English. It has less coding than other programming languages. Python runs on the interpreter, ie it executes quickly by writing code, and therefore the execution speed of the program is extremely high. Python is a procedural, object-oriented, and functional programming language. These have also increased the performance of Python.

Python can be used to create web applications on the server. And Python is also useful for creating workflows alongside software. Python connects to the database system and reads and modifies files and folders. The Python is a programming language for managing big data and doing complex math tasks.

Finally, Python is a powerful programming language for fast execution and software development. With these features mentioned and its widespread use on the web, Python is certainly widely used in the network for security. In the following , we will talk about increasing network security with Python .

Some great reasons for the importance of Python for network security

Undoubtedly, programming is an important part of network security in cyberspace. Especially when you are in the intermediate or advanced level of programming. Given that the Python programming language has been produced and published for many years, but in recent years this programming language has really attracted the attention of cybersecurity experts. This is to check if network security with Python is better than other programming languages.

But many believe that increasing network security with Python is very desirable, because it performs many functions related to network security and in malware analysis, scanning and intrusion testing, using learning curves and much more as It is the first language in which learning cybersecurity is recommended.

On the other hand, the design and operation of Python programming language has given it many advantages that make it a programming language for many fields such as data science, mathematical computing, web development and of course cybersecurity.

Python programming language is also very useful in execution

1.  Python is an easy-to-learn programming language that requires minimal coding to write.
2. Detecting errors by Python is easier than some other programming languages.
3. Python is an open source programming language.
4. Memory management by Python is automatic.

The importance of Python in network security

All of this helps us to better understand the Python programming language. Here are some key pointers in moving Python:

1. Fast coding and fast execution is a favorite program of cybersecurity experts that can be accessed by Python.
2. Network security team formation is done quickly using the Python programming language. This is because of the flexibility and simplicity of Python over other programming languages.
3. The valuable Python library is a tool that makes network security accessible.
4. Python programming language uses the closest things to network security.
5. In Python, scripts are rapidly evolving, which is the focus of network security experts.

Network security training with Python

As a computer expert, we need to know how to hack to stay safe from criminals. Access to the system and information that we do not have is called cyber hacking. That is, we gain access to outsider information without permission. Ethical hacking is a path that is identified using the weaknesses of an organization’s system and is reported to the organization for troubleshooting.

This article also follows this topic through Python. Since there is both ethical and immoral hacking in the concept of hacking, network security training with Python is important.

Next, we will hack the password using Python programming language. The importance of this is that choosing a simple password will make it easy to extract the password from the various passwords provided. This type of attack is called a library attack. We need to have access to a list of information to identify.

Password hacking with Python

Suppose a text file contains a list of passwords called password.txt.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100

<span style=“font-size: 16px;”>import hashlib print(“**************PASSWORD CRACKER ******************”) # To check if the password # found or not. pass_found = 0 input_hash = input(“Enter the hashed password:”) pass_doc = input(“\nEnter passwords filename including path(root / home/):”) try: # trying to open the password file. pass_file = open(pass_doc, ‘r’) except: print(“Error:”) print(pass_doc, “is not found.\nPlease give the path of file correctly.”) quit() for word in pass_file: # encoding the word into utf-8 format enc_word = word.encode(‘utf-8’) # Hasing a word into md5 hash hash_word = hashlib.md5(enc_word.strip()) # digesting that hash into a hexa decimal value digest = hash_word.hexdigest() if digest == input_hash: # comparing hashes print(“Password found.\nThe password is:”, word) pass_found = 1 break # if password is not found. if not pass_found: print(“Password is not found in the”, pass_doc, “file”) print(‘\n’) print(“*****************  Thank you  **********************”)</span>

Using the code written above, when entering the code by the user, the password is identified, otherwise an error is declared. For example, the user is asked to enter the encrypted password. Then enter the file name. Non-encrypted passwords are extracted using written commands. Consider the following two examples.

Entrance:

Output:

Entrance:

Output:

In these two examples, it was found that even if we have an encrypted password and access to the source in different ways, the password behind the screen, which is not displayed, will be encrypted in Python.

This type of hacking can occur in many online purchases, which should be very careful in this regard. Do not seek to learn Python hacking for malicious purposes. Hacking using Python to increase network security is very popular.

Penetration test tutorial with Python

Penetration testing is defined as an attempt to assess the security of an IT infrastructure by simulating a cyber attack on a computer system to prevent potential damage. It is further noted that there is a difference between penetration testing and scanning for system vulnerabilities.

A system vulnerability scan simply identifies vulnerabilities, but penetration testing is an attempt to exploit vulnerabilities.

Penetration testing helps to identify and identify unauthorized access or other malicious activity on the system. Penetration testing for servers, web applications, wireless networks, mobile devices and any other possible point is subject to the use of manual or automated technologies. In this section, we will code a part of the Python language to create a simple port scanner using a socket in Python. Note this Python script.

The output of this script will be as follows:

The outputs show that in the range of 50 to 500, the port scanner has detected two open ports 135 and 445. If we change the range, other ports will be detected.

This code was a small part of the intrusion test using the Python language . Certainly penetration testing for different networks and ports and types of inputs will be written with different codes and outputs. This coding will provide network security with Python . In the following texts, these programming codes will be mentioned to check the penetration test with Python.
