Wifi Attacks And Security Part

Friends as I have already announced
before that we would be writing on
Wifi attacks very soon, The series
consists of three parts( May be more
depending upon your feedback) and
will be covered by John Jeffrey. In
the first Part John explains about the
very basics of Wifi Attacks and
security. Before moving on to the
advanced stuff such as WEP and WPA
Cracking, You need to have the basic
idea of how a wifi connection works.
Wifi stands for Wireless Fidelity, Its a
device that performs the functions of
a router but also includes the
functions of a wireless access point
and a network switch.
They are commonly used to allow
access to the Internet or a computer
networks without the need for a
cabled connection. Wifi is commonly
used in airports , Offices etc
How Wifi Works?
The working of Wifi is pretty simple
to understand. The components of
wireless network includes a
communication device such as a
laptop or a cell pone etc, a router
and internet connection
The communication device which
has a wireless compatibility
( laptops )converts the data in the
form of radio waves and transmits it
to the router, through an antenna.
The router receives the signal and
decodes it. The router sends the
information to the Internet using a
physical, wired Ethernet connection.
The reverse communication follows
the same ( i.e) the router receiving
information from the Internet,
translating it into a radio signals and
sending it to the computer's wireless
adapter.
Whats the Danger?Security is an
important part of a home wireless
network. If you set your router to
create an open hotspot, anyone who
has a wireless card will be able to
use your signal. And he/she will be
able to use your internet
connection .
To protect and keep our internet
private we can use one the following
encryptions
WEPWired Equivalent Privacy (WEP)
is a weak security algorithm for
wireless networks. Its intention was
to provide data confidentiality
comparable to that of a traditional
wired network. WEP, recognizable by
the key of 10 or 26 hexadecimal
digits, Its widely in use and is often
the first security choice presented to
users by router configuration tools.
Although its name implies that it is
as secure as a wired connection, WEP
has been demonstrated to have
numerous flaws and has been
deprecated in favor of newer
standards such as WPA2.
WPA And WPA 2WPA (Wi-Fi
Protected Access) and WPA2 (Wi-Fi
Protected Access II ) are two security
protocols for wireless networks from
the Wi-Fi Alliance that was
developed to provide a migration
from WEP.
The Alliance defined these in
response to serious weaknesses
researchers had found in the
previous system, WEP
But these encryptions can also be
broken , The following demo shows
us how easy it is to crack WEP , WPA
keys
DemonstrationIn this following
demonstration Brain Young shows
us how easy it is to crack WEP , WPA
keys
How to Secure Your Wireless
Network
1. Never use WEP as your encryption
type, always use WPA Or WPA 2 as
your encryption type
2.Use strong passwords , which can
not be cracked easily by using a
dictionary attack or brute force
attack
3. Always Use a Vpn when your
using pubic Wifi hotspots
