Tsunami Network Security Scanner

We are going to need to _actively_ scan the network [**`@home`**](https://github.com/dwyl/home) because we want to have several "smart" features in the house which means having several unattended computers connected to the network.

We will have at _least_ **3 networks** within the house and one will be a DMZ https://en.wikipedia.org/wiki/DMZ_(computing) used by untrusted devices. Any devices on the _internal_ network should not be accessible be accessed from the outside.
Having a security-first network topology is a good start, but it's not a _guarantee_ that there are no malicious devices inside it. We need both monitoring and scanning.

Made/used by Google so you know it's got to be decent.
