Wireless networking provides mobility benefits by allowing users to work away from their home or office on devices like laptops and smartphones. However, wireless networks are vulnerable if not properly secured, as default security settings and open networks leave users at risk of hackers intercepting transmissions and stealing sensitive information or identities. To protect themselves, users should ensure their home network has been properly set up with security, check that any network is secure before connecting, and be selective about what content they transmit over public hotspots.
