How Does Firewall Work?
Posted: Tue Jan 07, 2025 4:03 am
Firewall examines the data traffic on the network with a predetermined filter. It blocks data packets coming from unsafe sources with the help of these filters. With this measure, it is possible to prevent malicious software and dangers coming from the internet.
The firewall system is located at the connection points where data is shared on the network. For example; the system with the source address 172.18.1.1 is allowed to reach the destination 172.18.2.1. This example best describes the process that the digital firewall does.
The operation of the Firewall digital security system is not a complex mechanism. The best way to explain this is to explain the subject with an example. Let's think of the IP address as the house and the port sweden telegram number as the room. Only approved and safe people can enter the house. A separate security filter is applied for people entering the house to reach the rooms. With the new connection points established, people entering the house are allowed to reach the rooms. In other words, the Firewall filter system performs control and supervision at multiple points.
We can say that the packet filtering mechanism of the old generation Firewall network security systems was a bit weak. Data packets were controlled through a basic filter mechanism. In some cases, requests from trusted sources were directly accepted. Over time, it was understood that not all requests from trusted sources were well-intentioned. This made it necessary for the Firewall system to develop. Today, it is seen that the established digital firewall system is constantly improving itself.
