PROXY
This is not the one which we usually put for our mates in the college :-) Proxy is a tool using which we can browse safely by hiding our ip. We can do lot more with it.

| this is how proxy works... |
A proxy or proxy server is
basically another computer which serves as a hub through which internet
requests are processed. By using proxy, whatever u request in the browser will reach the proxy instead of directly contacting the server. The proxy server then processes our request, sends our request to the server and gives us the search result which is returned by the server. In this way it serves as an
intermediary between your home machine and the rest of the computers on the
internet.
Proxies are used for a number of reasons such as to filter web content, to go around restrictions such as parental blocks, to screen downloads and uploads and to provide anonymity when surfing the internet.
TYPES:
·
Anonymous Proxy - An anonymous proxy server is also known as web proxy.
By connecting to the internet through this proxy, the home IP address of your
machine will not be shown but rather the IP of the proxy server will be shown. By blocking direct access between two networks, proxy
servers make it much more difficult for hackers to get internal addresses and
details of a private network.
· Distorting Proxy - This type of proxy server makes an incorrect original IP
address available through the http headers.
Transparent Proxy - A transparent proxy does not provide privacy. It means
that it does not add, delete or modify attributes or modify our request. It just
forwards our request as it is to the server and return the result to our
computer. Also it does not mask our ip. Our ip will be visible to the network. But these are generally used for their ability to cache websites.
Some more proxies are available and we can chose it based on our requirement.
CACHING:
Proxies may also cache web pages.
Each time the user requests an URL from their system, a temporary copy is
stored locally in the proxy server. When user requests the same URL for the next time, the proxy
can serve the local copy instead of retrieving the original across the network,
improving performance.
USES:
Finally, the uses of the proxies are:
*To keep machines
behind it anonymous(that is for hiding our ip address)
*To speed up
access to resources (using caching). Web proxies are commonly used to cache web pages from a web server.
*To access sites
prohibited or filtered by your ISP or institution.
*To log / audit
usage, i.e. to provide company employee Internet usage reporting.
*To bypass
security controls.
* To scan
transmitted content for malware before delivery.
CONS:
The
main problem with the proxy is that if you use untrusted proxies, then
your informations like your ids and passwords can be accessed by proxy
server. So use trusted and recognized proxy. Some proxies are free to use and there are proxies for which we've to pay(this type will be used
in the organisations). But make sure that the proxy you use is genuine.
SOME PROXY SITES:
Do
googling for more proxies and before you use, check for its genuinity. So try using proxies for accessing
information which you think others should not see.
It is a safe way to restrict hackers provided the proxy is
from trustworthy environment.
