<P> This stands for WLAN Authentication and Privacy Infrastructure . This is a wireless security standard defined by the Chinese government . </P> <P> This is a very strong form of security . When combined with some server software, the hardware or software card or token will use its internal identity code combined with a user entered PIN to create a powerful algorithm that will very frequently generate a new encryption code . The server will be time synced to the card or token . This is a very secure way to conduct wireless transmissions . Companies in this area make USB tokens, software tokens, and smart cards . They even make hardware versions that double as an employee picture badge . Currently the safest security measures are the smart cards / USB tokens . However, these are expensive . The next safest methods are WPA2 or WPA with a RADIUS server . Any one of the three will provide a good base foundation for security . The third item on the list is to educate both employees and contractors on security risks and personal preventive measures . It is also IT's task to keep the company workers' knowledge base up - to - date on any new dangers that they should be cautious about . If the employees are educated, there will be a much lower chance that anyone will accidentally cause a breach in security by not locking down their laptop or bring in a wide open home access point to extend their mobile range . Employees need to be made aware that company laptop security extends to outside of their site walls as well . This includes places such as coffee houses where workers can be at their most vulnerable . The last item on the list deals with 24 / 7 active defense measures to ensure that the company network is secure and compliant . This can take the form of regularly looking at access point, server, and firewall logs to try to detect any unusual activity . For instance, if any large files went through an access point in the early hours of the morning, a serious investigation into the incident would be called for . There are a number of software and hardware devices that can be used to supplement the usual logs and usual other safety measures . </P> <P> It's practical in some cases to apply specialized wall paint and window film to a room or building to significantly attenuate wireless signals, which keeps the signals from propagating outside a facility . This can significantly improve wireless security because it's difficult for hackers to receive the signals beyond the controlled area of an enterprise, such as within parking lots . </P> <P> Most DoS attacks are easy to detect . However, a lot of them are difficult to stop even after detection . Here are three of the most common ways to stop a DoS attack . </P>

Which of the following is the strongest form of wireless security and is easy to implement
