Sensible habits on networks you do not control
Open networks in cafés, hotels and airports are safer than they were a decade ago. A handful of ordinary habits closes most of what remains.

The advice about public networks has aged, and the reason is encouraging: the overwhelming majority of web traffic is now encrypted in transit by default. The dramatic scenario in which a stranger reads your email over a café connection is far less available than the warnings suggest.
What still deserves attention
- Confirm the network name with staff rather than picking the most plausible entry in the list. A convincingly named network is the easiest thing on this list to get wrong.
- Turn off automatic reconnection to open networks, so a device does not silently rejoin something that merely shares a name.
- Treat a browser certificate warning as a stop sign rather than a nuisance.
- Keep the operating system and browser current, which is where the meaningful protection actually lives.
- Enable two-factor authentication on accounts that matter, which limits the damage of a password disclosed anywhere at all.
The realistic summary is undramatic. Public networks are a modest, manageable risk for ordinary browsing on a maintained device, and the habits that reduce that risk are the same ones that serve you on your own network at home.
