What factor should be considered to ensure data security in a public setting?

To ensure data security in a public setting, using secure internet connections is vital. Public networks can be susceptible to various threats, including hacking and unauthorized access. By opting for secure internet connections, such as those protected by strong passwords and encryption protocols like WPA3, you establish a safer environment for transmitting sensitive data. This step minimizes the risk of data interception by malicious actors who often target unsecured networks.

In contrast, the other considerations do not adequately address data security. Turning off all devices may temporarily prevent unauthorized access but would be impractical and counterproductive for data work that requires connectivity. Working in places without surveillance may seem appealing, but the absence of oversight does not guarantee data security; it can actually increase risks if others can easily access the information. Sharing screens with others in a public setting poses a significant risk, as it can inadvertently expose sensitive information to unauthorized individuals nearby. Therefore, using secure internet connections is the most effective strategy for safeguarding data in public environments.
