![]() Think of a house where you live during the COVID-19 pandemic. Therefore in order to check the contents of a coming network and its history we set up a firewall.įirewalls are set up at the doorstep from where we access incoming network (The internet) and these firewalls constantly scan the incoming and outgoing data packages from our local network to the internet.Īnd if they found some suspicious packets or malicious activities within the network it immediately discards or terminates the package or activities respectively. So if we use this internet directly without knowing it’s the source or to be more specific without knowing its content what it contains, whom it is for, what this packet will do once it is on our local network, it becomes a high risk and each device on the network get vulnerable to cyber-attack. The ISP’s sends us the internet directly as they received, meaning along with their internet comes to every type of data package from authenticated as well as the unauthenticated source. In this interconnection of such a huge network, It becomes an utmost priority to secure our device as we don’t know from where the data is coming and for whom it is coming. So there are a lot of many and unknown devices out there which we don’t know what it is used for. The internet is a huge connection of devices globally, that is whatever devices are there on this planet it is connected to the internet. We access the internet at home, schools, colleges, or offices, these internet comes to us through internet service providers. ![]()
