How to Stay Safe on Public Wi-Fi Networks
Public WiFi
networks—like those in coffee shops or hotels—are not nearly as safe as
you think. Even if they have a password, you're sharing a network with tons of other
people, which means your data is at risk. Here's how to stay safe when you're out and
about.
Do I Really Need to Worry About Security When I’m Using
Public Wi-Fi?
Dear Lifehacker, I'm no idiot when it comes to security,
and you guys have often mentioned how …
Just because most wireless routers have a firewall to protect you from the internet
doesn't mean you're protected from others connected to the same network. It's
remarkably easy to steal someone's username and password, or see what they're
doing just by being on the same network. Don't take that chance. We're going to show
you which settings are the most important ones, as well as how to automatically
change your settings to the appropriate level of security every time you connect to a
public network.
Blast from the past is a weekly feature at Lifehacker in which we revive old, but still
relevant, posts for your reading and hacking pleasure. This week, we're reminding
everyone of the importance of WiFi
security when you're away from home.
The Settings
First, let's start by talking about what settings and apps can keep you safe. Make sure
these are enabled anytime you're on public WiFi,
whether it's password protected or
not. If other people you don't know are on the same network, you want to protect
yourself.
1. Turn Off Sharing
When you're at home, you may share files, printers, or even allow remote login from
other computers on your network. When you're on a public network, you'll want to
turn these things off, as anyone can access them—they don't even need to be a
hacker, and depending on your setup, some of that stuff probably isn't even password
protected. Here's how to turn off sharing:
