Few weeks, thanks
to my antivirus service, ago my friend realized that it had detected an
'intruder' in the local wireless network at my house, so my friend immediately
went to the options of the software to find out more. What was my surprise to
see the name of one of my neighbors followed by '-PC'? Needless to say, this
might put me out of my mind, but something about it did better.
At first, my friend
wanted to see if through the antivirus could find a way to block access from
the computer to my network, but only found a way to make this device as an
'unwanted' in the WLAN. The truth is that, despite warnings to change the type
of network security by the company providing the service me, my friend
preferred to leave everything as is the idea that "my neighbors are not
the type who would walk hacking my network to hang it. "How wrong my
friend was.
In fact, today it
is completely unnecessary to have advanced computer skills to do something like
previously mentioned. These physical places, as in any virtual internet
corner, one can find a way to do what you want, when you want; the best excuse
that can be found is to save a few bucks.
Having meditated on
all that, my friend thought of two options: Go directly home from my neighbors,
I know that the person whose name appears on my screen as 'So-PC' lives, and
ask them to stop taking my network, or more effective: Change once and for all
the safety of my service.
At first, we must
define what we mean by the term 'network
security'. That is, the type of encryption
used on the wireless network to restrict home computers that connect to it is
with our permission. These are:
-Low-level WEP
security is the type of security that have default most wireless networks.
-WPA-medium
security level: this type of security has a default password, but still quite
vulnerable.
-WPA2-high security
level: here a predefined password lets you create authentication keys for each
user (PSK) network is mixed.
The main advantage
of using WPA or WPA2 to WEP, besides the obvious, is that the WEP encryption
key has to be entirely easier to bend, while WPA authenticates users via a
server where credentials and passwords are stored of each. As you can not in all
domestic environments using a server with WPA have the option of a shared key
(pre-shared key or PSK), which is safer and enters all connected to the
network, as is done with WEP. In my case, my friend have enabled security is
WEP, ie the most vulnerable. Now we have to change it to a safer level, so my
friend will avoid more users around me infiltrate my WLAN.
Here we have
collected links to information published by the major internet providers in
Mexico with which you can access the settings of your wireless router and
change the encryption more secure. Webimprints is a network
security company that deals in such
threats. Posted by Webimprints.
