Introduction to Networking
Unlock Audio Lesson
Good morning class! Today, we're diving into networking and its critical role in cybersecurity. Can someone tell me what they think networking means?
Networking is connecting devices so they can communicate with each other.
Exactly! Networking allows devices to exchange data. This is essential in cybersecurity as many attacks are carried out via networks. Can anyone name different types of networks?
LAN and WAN are two types, right?
Correct! LAN stands for Local Area Network, which is local to a certain area, while WAN refers to Wide Area Network, like the Internet. Remember, LAN = Local, WAN = Widespread. Why do we need to understand these in cyber security?
Because attacks mostly happen over these networks!
Great connection! Understanding how networks operate helps us defend against attacks. Let's summarize: Networking connects devices, essential for sharing information, and is the primary target for cyber threats.

Let's dig deeper into network types. Can anyone explain what a LAN is?
A LAN connects devices in a small area, like a home or office.
Spot on! LANs are great for quick file sharing and communication within a limited space. Now, how about WAN?
That would be the internet, allowing devices over wide geographical locations to connect.
Exactly! And don't forget wireless networks, which let devices connect without wires, like Wi-Fi. What kind of issues might arise in local versus wide networks?
WANs might be more susceptible to attacks due to their vast access points.
Very good! In essence, knowing the type of network helps us understand potential vulnerabilities. Let’s recap: LANs are local, WANs are vast, and vulnerability increases with exposure.

What is Networking in Cyber Security?
Computer networking is the process of interconnecting different devices to enable the sharing of data and resources. This interconnectivity is crucial for cybersecurity because a significant proportion of cyberattacks happen over networks. The two primary types of networks are:
- LAN (Local Area Network): These are small networks typically confined to a single location like an office or home.
- WAN (Wide Area Network): This type encompasses larger geographical areas, with the Internet being the most prominent example of a WAN.
- Wireless Networks: These involve connection without physical wires, such as Wi-Fi networks.
Understanding these basic networking concepts is essential in identifying how networks operate and how they can be compromised, setting the foundation for cyber security strategies.

Computer networking refers to the interconnection of devices to share data and resources.
Detailed Explanation
Computer networking is the practice of linking different computing devices so they can communicate with each other. This includes sharing resources such as files, applications, and internet connections. Essentially, networking creates a system where multiple devices can work together efficiently, enabling collaboration and information exchange.
Examples & Analogies
Imagine a group of friends sharing a large library of books. Instead of each person having to buy every book separately, they connect their homes with a network of paths. Each friend acts as a node in the network, allowing them to easily share and borrow books, making access to information more efficient and collaborative.

In the context of cyber security, understanding networks is crucial because most cyber attacks occur over a network.
Detailed Explanation
Understanding networks is vital in cyber security because they are the primary pathways for data transfer. Cyber attackers often exploit vulnerabilities within these networks to gain unauthorized access to sensitive information or disrupt services. Therefore, a solid grasp of how networks function helps security professionals defend against potential breaches and implement protective measures effectively.
Examples & Analogies
Think of a city with roads connecting houses (the network). If one of the roads has a pothole (a vulnerability), it can be exploited by intruders (hackers) to access homes (devices) easily. Knowing the layout of the city helps to fix the potholes (vulnerabilities) and keep homes safe.

Networks can be:
- LAN (Local Area Network) – e.g., office/home network
- WAN (Wide Area Network) – e.g., the internet
- Wireless Networks – e.g., Wi-Fi
Detailed Explanation
There are different types of networks based on their size and functionality:
- LAN (Local Area Network): A network that is limited to a small geographic area, typically within a single building, such as your home or office.
- WAN (Wide Area Network): A network that covers a large geographic area, such as the internet, which connects many LANs together across cities, countries, and continents.
- Wireless Networks: These networks allow devices to connect without physical cables, using radio waves instead, like Wi-Fi in your home or coffee shop.
Examples & Analogies
Think of LAN like the group of friends sharing books in one room, while WAN is like a school district where several libraries (local networks) are interlinked. Wireless networks are like a park where friends can meet and exchange books freely without having to sit together in one specific spot.
