A set of exercises to help you learn about using computer security tools, and maybe help pass the Security+ exam. No promises though.
The CompTIA Security+ certification body of knowledge covering a number of concepts and tools. In the (section) titled "Technologies and Tools", you are introduced to a number of command line tools for Windows, Linux, and MacOS that can help you explore and troubleshoot local networks as well as remote systems and hosts.
It is my hope that I can provide a set of questions relating to each of the recommended tools that will give you real world examples and hands-on experience working with these tools. It is recommended you get familiar with these tools before you take the Security+ exam, according to Mike Chappel.
