Managed Network Switches

Managed Network Switches

This post is a continuation from my last post that covered network management. I’ll be showing how to use a managed network switch to identify and control the devices that connect on a network. These devices need a way to connect to each other and it is the switch that provides that physical connection. Wireless devices may seem like they are outside this realm, but they too connect to a switch through their access point. Network managed switches offer a…

VM Sandboxing with VirtualBox

VM Sandboxing with VirtualBox

Sandboxing is a term used to describe a computer environment that uses 1 or more computer systems that are logically separated from a production computer environment. The sandbox environment allows administrators to test conditions that will not influence the production environment. Unlike a lab environment that will replicate exactly what exists in a production one, sandboxing is primarily used to test behaviors. This post will cover how to use VirtualBox to create and operate a sandbox environment. It will not…
