Demonstrate how network communication works using Python sockets for basic cybersecurity tasks.

Business Scenario

Welcome!

A bank wants to develop a secure internal communication and login verification system where employees and users can send messages and login requests to a central server. The server receives data from multiple clients, verifies login credentials, and logs all communication for monitoring and security purposes.

Pre-Lab Preparation

Topic : Python Fundamentals for Cybersecurity

1) Introduction to Python for cybersecurity

2) Python basics (variables, data types,Input/Output operators, Conditional Statements, loops, functions)

You are working as a junior cybersecurity engineer and security analyst to develop and simulate this client-server communication system using socket programming.

Task 1: Secure Office Communication System

In this task, you will understand the basics of client-server architecture by creating a server that listens for incoming connections and a client that sends messages to the server. You will also establish communication between both systems to simulate real-time data exchange using socket programming.

Server Code (Message Receiver)

1

import socket

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

server.bind(("127.0.0.1", 5000))
server.listen(5)

print("Server is listening...")
while True:
   client_socket, addr = server.accept()
   print(f"Connection from {addr}")
   
   message = client_socket.recv(1024).decode()
   print(f"Employee Message: {message}")
   
   client_socket.send("Message received securely".encode())
   client_socket.close()

Output

Task 1: Secure Office Communication System

In this task, you will understand the basics of client-server architecture by creating a server that listens for incoming connections and a client that sends messages to the server. You will also establish communication between both systems to simulate real-time data exchange using socket programming.

Task 2: Create WireFrame

Now that you understand the requirements, don’t jump into coding yet. Before development, we always visualize the layout.

Now lets  create a simple wireframe for the homepage.

A wireframe is like a layout plan of a house. Before building, you decide where rooms, doors, and windows will be placed.Similarly, a wireframe helps you plan where elements like headers, images, and buttons will appear on a webpage—before adding design or colours.

Task 3: Code Editor Installation

Good work on completing the planning phase.

Now we will start development. Before that, make sure your system is ready with the required tools.

In this step we will install the VS code editor that will help to Write code efficiently,Organize files , Run and test your application

Go to the visual studio code official website
