Blocking with a Hosts File : Another hardening step....
Blocking with a Hosts File : Another hardening step....
1.
    How many of you know about the hosts file function in windows?It's a
 text file without a file extension that is intended to map IP addresses
 before accessing a domain name server to speed up the access. Now with 
the growing cyber concerns in the recent years,this mapping function is 
being additionally used to take a more preventative role in ad blocking 
and stopping spyware.This is located inside the 
>system32>drivers>etc folder.
2.   To explain it more simply 
When a address like http://www.bbc.co.uk/ is placed into your browser, 
the Hosts file is consulted to see if you have the IP address for this 
site. If you do, then you get directed to the site IP,but since most of 
the times it is not there,computer asks for the IP address from your ISP
 to find sites.
3.   It is here,that this 
function has recently been started to block ads, banners, 3rd party 
Cookies, 3rd party page counters, web bugs, and even most hijackers. In 
many cases using a well designed HOSTS file can speed the loading of web
 pages by not having to wait for these ads, annoying banners, hit 
counters, etc. to load. This also helps to protect your Privacy and 
Security by blocking sites that may track your viewing habits, also 
known as  "click-thru tracking" or Data Miners. Simply using a HOSTS 
file is not a cure-all against all the dangers on the Internet, but it 
does provide another very effective "Layer of Protection".

 is one site that I found worth as the purpose of this site is to 
provide the user with a high quality HOSTS file.This includes a ready to
 download hosts file that can replace your existing hosts file likely to
 be empty.The hosts file is kept updated on a regular basis.As on date 
the last update was available for 28th Feb 2012.So this site has a list 
of known ad and malware site IP addresses that are redirected at 
127.0.0.1.The site advertises saying " THERE IS NO PLACE LIKE 127.0.0.1.
