What Is Egress Traffic?

You may know that ingress is getting inside or sitting inside a car. While egress is the opposite, the process of getting outside the vehicle. This gives you an idea of where we are going. So let us begin. Any data or traffic going to an external entity that passes through the edge router of the host network is known as egress traffic. Edge routers are typically located at the edge of a network, meaning they are at the borders of a network and are used to connect networks and provide routing services. It's essential to keep in mind that egress traffic only sometimes originates from within your network. For example, suppose you have a server hosted on AWS (Amazon Web Service), and it's connected to your corporate network via VPN. All traffic between that server and other servers will be considered egress traffic even though it originated from Amazon's servers. You probably know that egress filtering is a popular network management technique if you're a network administrator. It scans all egress traffic for abnormality or malicious activity and discards infected data packets. So what does that mean? If you're not careful with your firewall settings, you could accidentally send out all sorts of malware to the world. Most people don't realize this, but the Internet is like a big party, and your firewall is like the bouncer at the door. Your firewall is there to make sure only good people get into your party and stay safe while they're there! It would be terrible if someone showed up at your house and you had yet to learn who they were or where they came from. However, even worse than that would be if someone tried to sneak through without an invitation. You must configure your firewall correctly to prevent this from happening.
