What is an essential action when using public Wi-Fi networks?

When using public Wi-Fi networks, it is essential to avoid accessing sensitive information. Public Wi-Fi networks are often unsecured, making it easier for cybercriminals to intercept data being transmitted between your device and the internet. This interception can lead to unauthorized access to personal information, bank details, or corporate data. Being cautious and refraining from accessing sensitive information—such as online banking or personal accounts—helps mitigate the risk of falling victim to data theft or cyberattacks.

The other options suggest practices that could potentially expose users to greater risk. For instance, sending confidential emails on an unsecured network can lead to interception of those emails. Connecting without a VPN increases vulnerability, as a VPN encrypts the data being transmitted, offering an additional layer of security. Sharing network access with others can further compromise security as it allows additional devices on the network, which may not be secure, to access shared resources. Thus, avoiding access to sensitive information is a prudent and essential action for maintaining cybersecurity on public networks.
