Each computer used for a penetration test must be configured to be accessible to the outside world. And the configuration must be secure so that outside hackers cannot gain access to the computers.
Penetration testing can be as simple as a laptop loaded with commercial hacking tools, or as complex as a network of computers connected by a virtual private network. Each method has its own strengths, and even though they are similar they each have their own benefits and drawbacks.
A virtual private network is actually a private network that is built on top of the public Internet. It starts with a private network, which is the network connection between computers. Then, it uses a private tunnel, which allows data to be transferred from one private network to another. This tunnel is encrypted so that it is secure, and it is also hidden on the public Internet. 827ec27edc
