A firewall is like a security guard at the entrance of a building. It's a protective system that watches over the traffic coming in and going out of a computer network, such as the internet. Imagine you have a special rule book that says who's allowed to enter the building and who's not. The firewall uses a set of rules, just like that book, to decide which data is allowed to pass through and which should be stopped. It acts as a barrier between your network and the outside world, making sure that only safe and approved data gets in, while blocking any potentially harmful or unauthorized data. It's like having a guard that checks everyone's ID at the door to make sure only the right people can come in, keeping your network safe from cyber threats.<\/p>\n","protected":false},"excerpt":{"rendered":"
