What is the main difference between inbound and outbound traffic?

The distinction between inbound and outbound traffic is essential for understanding network behavior and security management. Inbound traffic specifically refers to data that originates from an external source and is entering the network. This includes any requests or information coming from outside entities, such as users accessing a website hosted on the network or external servers communicating with devices inside the network.

Inbound traffic is crucial for services that need to respond to requests or communicate with clients, such as web servers, email servers, or other services that rely on client requests. Properly managing inbound traffic is vital for network security, as it can potentially introduce vulnerabilities or unwanted access points if not properly controlled.

On the other hand, outbound traffic pertains to data that is leaving the network and going to an external destination. Understanding the flow of both types of traffic is key to implementing effective firewalls, setting up security policies, and monitoring for suspicious activities.
