Sniffer, Spoofer & Portscanner

It's not necessarily an evil intention behind these actions: it's fully legit to check your own network for possible vulnerabilities. Maybe some intruder is already inside? Or there's some service running that shouldn't be? Did the admin forget to close some port in the firewall?

From scanning foreign networks without explicit permission you should refrain, though. Not only this could trigger some (false?) alert (as nobody would have expected your action), but also could have legal consequences. Oh: and don´t forget to be aware of „sniffers“ riding piggy-back on the apps (ad/analytics modules calling home)

In case those words don't mean anything to you, some short explanations:

Sniffing: intercept and log traffic passing over a digital network
Spoofing: pretend to be someone/something different than you are (masquerade as another by falsifying data)
Portscan: Looking for the "open barn door" (which ports are open?)
