Python

Install Python, set up a virtual environment, and write your first scripts using variables, types, and input/output.

Master if/elif/else, for and while loops, and write reusable functions with arguments, return values, and default parameters.

Work with Python's core built-in containers: lists, tuples, dictionaries, and sets — and apply them to real security use cases.

Read, write, and parse files in Python — including text logs, CSV reports, and JSON configuration files used in security tools.

Build classes and objects to model security tools — encapsulate scanner logic, extend base classes, and use dunder methods.

Use Python's socket module to build TCP/UDP clients and servers, scan ports, grab banners, and understand low-level network communication.

Use the requests library and BeautifulSoup to make HTTP calls, scrape web content, probe APIs, and automate form submissions.

Master Python's re module to write patterns that extract IPs, timestamps, usernames, and anomalies from real-world log files.

Run shell commands from Python using subprocess, automate system tasks with the os and pathlib modules, and build security automation scripts.

Bring together everything learned — OOP, sockets, threading, file I/O, and argparse — to build a production-quality multi-threaded port scanner with JSON and CSV output.
