People expect public Wi-Fi at nearly all the places we go and expect to be connected all the time. Wi-FI users regularly connect to Wi-Fi in their homes, but they require mobility. According to the survey of Xirrus, a Wi-Fi tech company, 49% of them connect to public Wi-Fi at least three times a week, and 31% connect everyday. 89% of users connect to more than one network a day because people would switch to home and work Wi-Fi networks which are private, safe and only accessible to selected users. In addition, 70% of users are even willing to change hotels for better connection and security, but the need to be connected overcomes security concerns. Few public Wi-Fi networks encrypt and protect our data when we connect. This means private information are at risk of being stolen every time a person connect to a public Wi-Fi. Although 91% of the respondents admit that public Wi-Fi is insecure, 89% use it anyway. That means most of users are aware of the security risk of public Wi-Fi, but most of them decide to ignore it. The good news is that most public Wi-Fi networks holding by restaurants, airports or hotels are required to upgrade to provide better security for customers. Over public Wi-Fi, 83% of users access their emails, 68% of users access social medias, and 18% even log in for online banking. Although most of users know phishing, but there are still 30% of users unfamiliar to ransomware that is a malware installed on a victim’s computer, executes attacks to encrypt or access to your data and demands a payment to decrypt it or not publish it. The number of victims and the amount of demanded payment keeps increasing. 85% of users would blame themselves for. hacks, while only 32% would blame Wi-Fi vendors and 24% would blame the venue. Wi-Fi users have to take the burden because most business do not educate their employees or provide necessary tools to help them stay safe. 46% of employees said that they didn’t receive any security training, and only 39% said they received one to two trainings in the past year. Companies should have their employees educated and trained regularly to ensure that they are always aware of the importance of security and won’t put their personal or work-related information under the risk of being exposed. However, there is still a large gap between employers encourage secure behavior and those do not. 47% employees are encouraged to use VPN for working when they are traveling for business. The good news is that most public Wi-Fi networks holding by restaurants, airports or hotels are required to upgrade to provide better security for customers.
