When you interact with any website or online application, you are sending data to them. This data is how you speak with the website. When you want to visit a website and you type the address into your search bar your computer sends a signal out to the website host and they send one back allowing you access (or in some cases denying it). However, it is not nearly as straight forward as it sounds.
The data signal that you are sending out goes through a variety of other routers on the way to its destination. This is just a basic example:
This signal being sent to so many different places makes it an easy target for cyber criminals. If they are able to latch onto the signal going in or out of a host server they can effectively piggyback their way onto your device. We will talk about that piggybacking and ways to defend against it in a future post.
The data signal that you are sending out goes through a variety of other routers on the way to its destination. This is just a basic example:
- You send a signal to google.com
- The signal goes to your personal router then to your internet providers router.
- From there it travels to other routers from your internet provider, depending on how far away the host server is.
- Meaning, the farther away you physically are from the google server, the more routers your data will travel through to get your signal to google.
- Once your signal passes through the different routers and reaches its destination, a return signal is sent and goes through the the same path back and access is given.
