Proxy servers run between users and the web pages they visit online, known as "mediations," and proxies provide a valuable layer of security for your computer. Can be set up as a network filter to protect your computer from Internet threats such as malware. Some people use proxies for personal purposes, such as hiding their IP location; Companies are also using proxies, for example, to crawl network data and analyze it to improve business efficiency. So, how do proxy servers protect information security?
The proxy server performs firewall and filter functions. End users or network administrators can choose agents designed to protect data and privacy. This checks the data going in and out of your computer or network. It then applies rules to prevent your IP address from being accessed by a third party. Hackers or other malefactors can only see the IP address of the proxy. Without your personal IP address, people on the Internet can't directly access your personal data, schedules, applications or files.
With a proxy server, the request is sent to the proxy, which then gets the information you want from the Internet and returns it to you. Passwords and other personal data get an extra layer of protection if the server has encryption.
