Wireless signals are electromagnetic in nature hence they travel with
approximately the speed of light. They can also be referred to as radio
frequency waves because they can pass through walls or reflected by
metal.
Types of wireless networks
Personal Area Network (PAN) like bluetooth, wireless mouse e.t.c
Local Area Network (LAN)
Metropolitan Area Network (MAN)
Wide Area Network (WAN)
Dangers of wireless networks
Installing a wireless network in an organization without security gives
room for unauthorized people to access your internet facility.
Also, hackers can connect antennas to a vehicle and drive round the
organization location in order to detect wireless network so that they
can break into the organization's data.
Wireless security
There three categories of wireless networks security namely:
Authentication
Encryption and
Intrusion Prevention System (IPS)
Authentication: it has to do with certificate authentication.
Whoever wants to access the wireless network must present the correct
certificate of authentication otherwise he won't be able to gain
entrance into the network.
Encryption: Wireless networks can also be secured encryption i.e
every data sent across the network are encrypted or scrambled so that
whoever is trying to hack the network will get the encrypted or
scrambled version all data. Only an authorized person will have the
public keys for decrypting the encrypted data.
Intrusion prevention system (IPS): it detects illegal wireless
network connection that may want to interfere with the wireless network
of the organization. It ensures that only authorized wireless access
point are allowed.
It gladdens my heart when ever am
