What is Public Wi-Fi and How Does it Work?
Public Wi-Fi is a type of wireless network that is open to the general public, allowing users to access the internet for free or at a low cost. These networks are often found in public hotspots such as coffee shops, airports, hotels, and libraries. Public Wi-Fi works by transmitting internet signals through a wireless router, which is connected to a physical internet connection. This allows users to connect to the internet using their devices, such as laptops, smartphones, and tablets.
The convenience of public Wi-Fi is undeniable, as it allows users to stay connected on-the-go. However, this convenience comes at a cost, as public Wi-Fi networks are often insecure and vulnerable to cyber threats. This is because public Wi-Fi networks are often unsecured, making it easy for hackers to intercept data and steal personal information.
What are the Risks of Using Public Wi-Fi?
The risks of using public Wi-Fi are numerous and alarming. One of the biggest risks is the potential for hackers to intercept sensitive information such as passwords, credit card numbers, and personal data. This can happen through a technique called “man-in-the-middle” attacks, where hackers position themselves between the user and the wireless router, allowing them to intercept data as it is transmitted. Additionally, public Wi-Fi networks can be infected with malware, which can be spread to devices that connect to the network.
Furthermore, public Wi-Fi networks often lack encryption, making it easy for hackers to access data. Even if a password is required to access the network, it is often easy to guess or hack. In addition, some public Wi-Fi networks may be set up by cybercriminals with the sole intention of stealing personal information. This is known as a “rogue hotspot” and can be extremely difficult to identify.
