Security
Because wireless networks rely on radio signals to transmit data, they are not as secure as
wire network. Wireless networks are susceptible to viruses and breaches like eavesdropping
and need to be protected in order to be secure.
There are many security measures to safeguard wireless networks, protect the data, and
keep unauthorized users out. Hotspots, on the other hand, are often free of standard security
practices in an effort to make it easy for anyone to connect. It may be found that some pay
hotspots administered by service providers offer have some level of security, however, when
using a hotspot, it ’ s always a good idea to be proactive and to employ security measures of
your own.
