Introduction
What?
Build a virtual local testlab.
Why?
Pentesting needs a lot of practice before you actually approach a client to do the same on their live system.
It provides a simulated environment, your main system is not touched. If you break your operating system by mistake while experimenting with any hacking-related tools, it happens inside your virtual system. You can reinstall the damaged operating system again.
We have to stay within the law—always. We must practice our hacking-related tools in a legal way on our own systems.
You can safely browse any websites in a virtual environment. If some malicious code enters into your simulated environment, let it stay; it won’t touch your main system. You can do every type of testing on it.
