Basics of socket programming
Welcome to the /"Socket Programming Fundamentals/" section of the Cybersecurity for Critical Infrastructure project.
Sockets, also called network sockets, are the fundamental building blocks of network communications. They facilitate data transfer between a client (your device) and a server over a network, such as the Internet. Using sockets allows programs to communicate and exchange data, making them essential for a variety of applications, including web browsing, email exchange, file transfers, and of course, cybersecurity.

Why are electrical outlets important in cybersecurity?
Network Security: Secure communications are at the heart of defending critical infrastructure against cyber threats. Sockets enable the implementation of encrypted channels and data transmission protocols, ensuring data integrity and confidentiality.

Threat detection: Cybersecurity professionals use socket programming to monitor network traffic, detect anomalies, and identify potential intrusion attempts or malicious activity.

Incident response: During a cybersecurity incident, sockets help collect real-time data and evidence for analysis, helping incident response teams contain and mitigate the attack.

Key Concepts in Socket Programming
IP address: An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a network. It serves as the address that allows devices to send and receive data over the Internet.

Port: A port is a communications endpoint used by programs to establish connections on a network. It acts as a door through which data can flow in and out of a device. Ports are identified by numerical values.

Protocols: Protocols are a set of rules that determine how data is sent and received between devices. Common protocols are TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).

Client-server model: Socket programming follows the client-server model, where one device (the server) provides services to other devices (the clients) on the network. Clients initiate requests to the server and the server responds accordingly.

In this section we will explore the basics of socket programming, socket types, socket protocols, and socket methods. We also cover practical examples of socket programming in Python, C, or other programming languages commonly used in the cybersecurity field.

Whether you are a beginner or an experienced cybersecurity professional, this section will provide you with a solid foundation in socket programming to enhance your skills in securing critical infrastructure and mitigating cyber attacks.

Let's dive into the world of socket programming and discover its power in securing our critical systems!
