Introduction What makes a server a server? What does one look like? What are things that one can serve up? How is it different than a desktop or workstation? Can a workstation be a server? What the heck is the “cloud”? Why is this important to understand for Cyber Security?

What makes a server a server? It hosts services It handles multiple users It is up and running most of the time It is accessible remotely

What does a server look like?

What are things that one can serve up? Websites Data storage Databases Remote consoles Music Video Many, many, others….

How is it different than a desktop or workstation? Typically stays in one place Allows multiple users at the same time Has a dedicated purpose Built with reliable components Designed with redundancy in mind May prioritize disk speed, network bandwidth, CPU processing, but typically not graphics

Why is this important to understand for Cyber Security? Need to understand how data flows Need to understand services and their vulnerabilities Need to understand where access points are and how to protect them More?

Can a workstation be a server? Yes! Think of Kali Linux VMs and accessing them via SSH…..

What the heck is the “cloud”? A group of services Hosted in different places Allow access to many services Replicated data

Conclusion Servers are robust computing platforms They are reliable and redundant The allow multiple users The do and allow all kinds of cool stuff! They are important because the Internet and networks in general are built around servers
