Vk9 Security - Learn Python & Hacking (from Zero to Hero)

Define and assign variables in Python, use various data types such as integers, floats, strings, booleans, lists, and dictionaries, and print them; distinguish local and global variables and naming restrictions.

Explore Python strings by defining text, concatenating with plus or join, indexing and slicing, and using built-in methods; encode data with Unicode and base64 while learning immutability.

Learn Python built-in functions, including print, len, type, range, and input, plus type conversions for str, int, float, and data structures. Explore dir and help for object documentation and examples.

Explore Python numbers, including integers, floating point numbers, and complex numbers, and learn arithmetic, type conversions, formatting, and built-in functions such as abs, pow, and divmod.

Learn how Python booleans define true and false, use and, or, and not to build expressions, and evaluate comparisons like x<y and x==y; discover boolean conversion with bool and isinstance.

Explore python lists as mutable, ordered collections defined by square brackets. Master indexing, slicing, and common methods like append, insert, pop, sort, reverse, index, and count.

Learn Python dictionaries through definition, creation, and common operations like access, iteration, adding and removing key-value pairs. Explore built-in methods, nesting, and using keys to retrieve values.

Discover python tuples as immutable, ordered sequences; create with or without parentheses, index, concatenate, unpack, nest, and use methods like len, count, index, sorted, max, min, any, all.

Explore Python sets: understand unordered, unique elements, hashable requirements, and set building methods; perform add, clear, copy, difference, intersection, union, and update with practical examples.

Master python conditional statements, including if, elif, and else, using comparison and logical operators, and explore ternary operations, indentation, and short-circuit evaluation to control program flow.

Explore Python for loops and the break, continue, pass, and else statements, using range, enumerate, and zip with lists, tuples, strings, and nested loops.

Learn how Python while loops work, with condition evaluation before each iteration, and how to use break, continue, pass, and else blocks, including counting and user input examples.

Learn how Python functions use def, parameters, and return to create reusable code blocks. Explore default values, args, kw args, nested and recursive calls, docstrings, and higher order programming.

Learn how Python modules organize code, define functions and variables, and how to import with import or from, create your own modules, and use built-in modules like requests.

Learn Python error handling with try and except blocks, and use finally, raise, and assert to catch, handle, and manage exceptions while safeguarding programs.

Explore debugging basics, including print debugging, debugger based methods with gdb, log based debugging, automated testing, and the Python breakpoint function with practical commands.

Explore networking concepts and protocols, including routers, switches, modems, firewalls, access points, and NICs, and learn how data moves across layer two and layer three devices.

Understand the OSI system interconnection model, developed by ISO, as a seven-layer framework for data transmission and cross-system communication. Identify the roles of physical through application layers in real networks.

Explore packet capture concepts using Wireshark, analyzing http traffic from tcp handshake to get requests and http responses, and examining ethernet, ip, and application layer details.

Learn the CIA triad of confidentiality, integrity, and availability, the triple-A framework of authentication, authorization, and accounting, and key practices in risk assessment, threat detection, and incident response.

Learn to use the python requests library to perform HTTP requests, manage headers and cookies, pass parameters in URLs, and send data for web scraping and API testing.

Install and use Beautiful Soup 4 to parse HTML and XML, extract text, images, and links, and convert web content to JSON, CSV, or XML with requests.

Explore Scapy, a Python library for crafting, sending, sniffing, and analyzing network packets, with installation guidance and practical packet creation, filtering, and replay for penetration testing.

Learn Python-nmap, install the library, and run nmap scans with Python to perform host discovery, port scanning, OS and service detection, and vulnerability checks with csv or json outputs.

Explore Python Paramiko to enable ssh connections to remote servers, covering installation, common methods like transport and sftp, and a runnable example of command execution.

Learn to generate csv reports in Python using the csv module, including writing and reading csv files with dict writer and dict reader, handling dialects and headers.

Learn to generate PDF reports using the Python FPDF library, including installation with pip and creating documents with pages, fonts, images, and text.

Explore threading in Python using the threading module, learning how to create, run, and join threads, and synchronize shared data for concurrent execution.

Explore the Python subprocess module to spawn and manage external commands and processes, capture output, and securely execute tools across platforms using methods like run, check_output, and Popen.

Learn object oriented programming in Python by mastering classes and objects, encapsulation, inheritance, and polymorphism, then create a simple class with an init method, self attributes, and methods.

Master a Python script to read and change a Mac address on a network interface, using regex and subprocess calls on Linux or Windows.

Learn to build an arp scanner in Python using Scapy to discover hosts on a local network by mapping IP addresses to MAC addresses through ARP requests and replies.

Build an ICMP scanner to discover live hosts by sending ICMP echo requests and analyzing replies with a subprocess ping workflow, and plan port and vulnerability scans.
