Wireless Internet access private files are easily shared

With the popularity of laptops with wireless Internet technology and the expansion of wireless Internet coverage, many "local" people prefer to surf the Internet in public places that provide wireless Internet services. However, a computer expert from Chongqing University warned that in this type of public Internet access, you should first check whether there is a folder or drive attribute in the pen computer that is set to "shared ", to ensure file security, cancel file sharing before accessing the Internet.

The expert said that some hotels, airport terminals, and large conference halls now provide wireless Internet access services free of charge in areas covered by wireless Internet access signals, A laptop with a wireless network adapter automatically finds a signal after it is started, and automatically sets the network connection attribute of the notebook, soon your laptop will be in the same LAN as other laptops that have already accessed the area. If your computer has a folder or disk attribute set to "share", it has not been canceled yet, then other Internet users in the LAN can see your shared folder or files on the disk.

Experts also reminded that in a wireless Internet access area covered by a wireless router, multiple netshers use the network at the same time. Some hackers may also use hacker software to easily view files on your computer. Therefore, you must have security awareness when accessing wireless networks. Considering that the current network transmission confidentiality technology is not complete, in such cases, do as little as possible operations such as online payment involving bank accounts and credit card passwords to avoid unnecessary losses due to password leakage.
