Core Operating Principles in Networks

Next-Generation Inspection (NGFW) that combines firewalling, intrusion prevention (IPS), web filtering, and malware scanning in one engine.

Stateful Inspection & Context that tracks active connections and analyse traffic context, ensuring return traffic is allowed only if a legitimate request was initiated from within the trusted network.

 Application Control which identify the specific application instead of ports, such as WhatsApp, Salesforce, or Zoom, and apply policies based on application identity rather than port number.

Deep Packet Inspection (DPI) & SSL/TLS Inspection that decrypt encrypted traffic, inspect it for malicious code, and re-encrypt it to ensure visibility into secure (HTTPS) threats.

Key Components in Real-World Deployment

FortiOS which is a  single, unified operating system powering all FortiGate appliances, ensuring consistent security policies whether in hardware, virtual machines, or cloud environments.

FortiGuard Labs AI Services which Provides real-time threat intelligence feeds that keep the firewall updated on the latest malware, IP addresses, and phishing sites.

Custom ASIC Architecture which is Purposely-built security chips (Content Processors and Network Processors) offload traffic analysis from the main CPU, allowing for high-performance security inspection

Common Real-Network Scenarios

Edge/Perimeter Security: It is Positioned at the network edge, FortiNet protects the network by acting as a 24/7 filter, scanning incoming and outgoing traffic.

SD-WAN Integration: They are often deployed as secure SD-WAN devices to optimize branch office connectivity, choosing the best path for applications while ensuring security at the edge.

Network Segmentation: They segment internal networks to isolate sensitive data zones, reducing the lateral movement of threats if one area is compromised.

Zero Trust Network Access (ZTNA): They provide secure remote access by verifying users and devices before allowing them to access specific applications, regardless of whether they are on-premises or remote

Traffic Flow Analysis

When a packet enters a FortiGate:

Ingress: The traffic is monitored and captured.

Inspection: The packet is compared against security rules.

Security Processing: ASIC processors perform IPS, Antivirus, and Application Control.

Decision: The traffic is Allowed or Blocked based on predefined rules.

Logging: Detailed logs and alerts are sent to fotianalyzer for visibility.

In today’s world, Computer networking plays a vital role in the IT industry. If the computer networks stop working for a short period, many tasks can be disrupted. Basic knowledge of networking is essential, as devices rely on a set of communication protocols to exchange data over wired and wireless connections. Understanding networking fundamentals can open up various career opportunities in the IT sector.

What is computer networking? Computer Networking is the interconnection of computing devices, such as computers, servers, and IoT devices, that communicate with each other to share data and resources. Computer networking is widely used in schools, hospitals, banks, colleges and the IT sector.

What are the types of computer networking that are covered in network basics? Computer networking has four main types:-

Local Area Networks or LAN – It is a private network that connects computers, devices, and servers within a small, limited geographic area, such as a home, office, or single building and offers high-speed data transfer rates, private ownership that is usually managed by one person or organization and components that consist of devices, cables, network switches and routers.

Wide Area Networks or WAN – It is a large-scale computer network spanning broad geographical areas such as cities, countries, or continents, connecting multiple smaller local area networks with common technologies including MPLS, SDWAN and Leased lines.

Metropolitan Area Networks or MAN – It is a high-speed computer network that connects multiple local area networks across a city, town, or large campus, typically spanning 5 to 50 kilometres.

Wireless Network – It is a computer network that uses radio waves, infrared, or satellite signals instead of cables to connect devices like laptops, phones and IoT devices. We have 3 types of wireless networks that are wireless LAN (WLAN), Wireless PAN (WPAN), Wireless MAN (WMAN) and Wireless WAN (WWAN).

Basic Networking Concepts Every Beginner Must Know Essential networking basics include IP addresses, DNS, DHCP, gateway, MAC Address, Ports and Protocols.

IP Addresses (Internet Protocol) are a logical, numerical address assigned to a device on a network, used to identify and route data to that device. IPv4 is a 32-bit IP address, whereas IPv6 is a 128-bit address. We also have public and private IP addresses. Public IPs are visible on the internet, and Private IPs are used inside local networks.

Media Access Control (MAC) Address is a unique 48-bit physical address assigned by the manufacturer to the network interface card. It identifies the physical device on a local network.

The Domain Name System (DNS) is used to translate human-readable domain names into computer-readable IP addresses.

DHCP (Dynamic Host Configuration Protocol) is a dynamic IP address that is automatically assigned, subnet masks, and default gateways to devices, preventing manual configuration.

Gateway is the router address that connects your local network to the wider internet.

Ports are the numerical identifiers that allow a single IP address to support multiple services

Protocols are the standard rules for communication. The types of protocols are HTTP/HTTPS, TCP/IP, UDP, SSL/TLS, SFTP/SSH, DNS, FTP and SNMP, etc.

Understanding the OSI Model (Layer by Layer) OSI Model stands for Open System Interconnection, which divides the communication process into seven distinct layers, each responsible for specific functions related to data transmission and network communication.

Layer 1- Application layer.- In this layer, we get the user interface, where apps like web browsers or email clients connect to the network.

Layer 2- Presentation layer – This layer translates, encrypts, and compresses data so the application layer can understand it.

Layer 3- Session Layer – This layer manages sessions or connections between computers, opening, closing and managing dialogues.

Layer 4 – Transport Layer – This layer handles end-to-end communication, ensuring data arrives, often using protocols like TCP or UDP.

Layer 5 – Network Layer – This layer decides the best physical path for data using IP addresses to send packets across different networks.

Layer 6 – Data Link Layer – This layer prepares data for the physical network, handling MAC addresses and node-to-node transfer.

Layer 7 – Physical Layer – This layer transmits raw bits (0 &1) over physical hardware, such as cables, connectors, or Wifi.

The OSI model is important because it standardises networking, allowing diverse, multi-vendor systems to communicate seamlessly using a 7-layer framework.

TCP/IP Model Overview TCP/IP Model is an integrated four-layer model, standardized framework that defines how data is transmitted over networks and the internet, acting as the foundational language for communication between devices.

The Four Layers of the TCP/IP Model are The Application Layer is the computer networking layer where data is generated and handled, directly interacting with applications. It includes protocols like HTTP, FTP, SMTP, and DNS.

The Transport Layer is a layer that manages end-to-end communication, ensuring data integrity through error control and sequencing. It uses TCP or UDP.

The Internet Layer is the layer that is responsible for logical addressing and routing packets across different networks.

The Network Access layer is the layer that handles physical hardware, MAC addresses, and formats data for the specific physical medium.

Networking Devices you must learn A router is a networking device that connects multiple networks, such as your home network and the internet and acts as a traffic director, directing data packets to their proper destinations.

A switch is a hardware device that connects, disconnects, or redirects electrical currents or data packets.

A firewall is a network security system that acts as a barrier between trusted internal networks and untrusted external networks, monitoring and controlling traffic based on security rules.

An Access Point is a networking device that creates a wireless local area network, typically in an office or large building, by acting as a bridge between wired Ethernet cables and wireless devices.

A modem is a networking device that acts as a bridge between your home network and your internet service provider.

There are also essential networking skills for beginners to learn, that are subnetting basics, troubleshooting commands and network security basics.
