Functionkey explores Information Technology (IT)

This Blog by the folks at Functionkey, Inc. covers the world of networking and security. The world of networking and security can be a little confusing. So, to make things easier, we have created this Blog to help you get started!

Networking and Security is a huge field that is constantly changing. There are many different types of networks and ways to secure them. In this guide, we will cover the basics of networking and security so that you can start off on the right foot.

We will cover topics such as Network Address Translation (NAT), Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Static Routing, Firewalls, and Load Balancers. We’ll also talk about Zero-Day Exploits and some common network attacks, such as DDoS, and how they work!

If you have a passion for information technologies, then join Functionkey Inc. in exploring this world!
