54% of PC users admit to using Wi-Fi

According to a new study by Sophos (UK), 54% of computer users worldwide acknowledge the "wireless" of other people's Internet without permission.

Sophos said many Internet-connected households cannot protect their wireless access with passwords and encryption. They almost "open the door" for passers-by and neighbors stealing access, and of course these "stealing" people don't have to pay for any Internet service providers (ISPs). In addition, although businesses often have security measures to protect Wi-Fi networks in the office, Sophos experts still note that employees use Wi-Fi remotely (employees working at home) may be a threat to enterprise security.

With Wi-Fi Internet access technology appearing more and more, the use of temples is also proportional. Because for many people, hacking into Wi-Fi access network is not difficult.

' Stealing Wi-Fi Internet access is seen as a crime without victims, but it leaves ISPs losing revenue. What's more, if you use the neighbor's wireless broadband network to download uncooperative movies and music on the Net, the Internet access network and the owner's speed of access will be slow and affected ', Graham Cluley, Sophos senior technology advisor, said. ' So most ISPs set terms in their contracts that require users not to share access with neighbors - but it's difficult to do this .'

Sophos recommends that home and business owners use wireless Internet to set up networks with the highest security measures, ensuring strong encryption in time to prevent hackers from using hackers and hackers. The ability to steal username (username), password (password) and other important information.

' If you don't encrypt your wireless network, virtual criminals will keep track of what you're doing, whether it's just surfing the Net or accessing remote work documents. Even, they can make your computer infected with malicious code to steal personal identity information , "Cluley continued. ' Therefore, Wi-Fi connection needs to be encrypted, and make sure your password is not easily guessed or attacked. The difficulty is that many Wi-Fi devices are not properly configured '.
