Whenever I talk or write about my own security setup, the one thing that surprises people — and attracts the most criticism — is the fact that I run an open wireless network at home. There’s no password. There’s no encryption. Anyone with wireless capability who can see my network can use it to access the internet.
To me, it’s basic politeness. Providing internet access to guests is kind of like providing heat and electricity, or a hot cup of tea.
