What are some concerns for using a public Wi-Fi network in a coffee shop, airport, or school campus, for example?
What will be an ideal response?
When using a public Wi-Fi network in a coffee shop, airport, or school campus there are also security concerns. First, these networks are rarely protected (in order to allow easy access by users), so attackers can read any wireless transmissions sent to and from the user's device. In addition, an attacker may set up an evil twin. An evil twin is an AP or another computer designed to mimic an authorized Wi-Fi device. A user's mobile device may unknowingly connect to this evil twin instead of the authorized device so that attackers can receive any sensitive transmissions or directly send malware to the user's computer.
