The request that is made to pass through the private network protected by firewalls will need a proxy server that is not abiding by any of the local policies. So, it is the prime duty of reverse proxy to redirect the flow depending upon the configurations of internal servers. Moreover, it is transparent to external users as external users will not be able to identify the actual number of internal servers. Reverse Proxy Server: The job of a reverse proxy server to listen to the request made by the client and redirect to the particular web server which is present on different servers.Įxample – Listen for TCP port 80 website connections which are normally placed in a demilitarized zone (DMZ) zone for publicly accessible services but it also protects the true identity of the host.Security: Proxy server is used to encrypt your web requests to keep prying eyes from reading your transactions as it provides top-level security.It will change the IP address and identify the information the web request contains. Privacy Benefits: Proxy servers are used to browse the internet more privately.Bandwidth savings and improved speeds: Proxy helps organizations to get better overall network performance with a good proxy server.Organizations use it, to deny access to a specific website and instead redirecting you with a nice note asking you to refrain from looking at said sites on the company network. To control internet usage of employees and children: In this, the Proxy server is used to control and monitor how their employees or kids use the internet.Examine Packet headers and Payloads: Payloads and packet headers of the requests made by the user nodes in the internal server to access to social websites can be easily tracked and restricted.Filtering of Content: By caching the content of the websites, Proxy helps in fast access to the data that has been accessed very often.To prevent such kind of misuse of Data Proxy servers are set up to prevent tracking of original IP addresses instead data is shown to come from a different IP address. Defeat Hackers: To protect organizations data from malicious use, passwords are used and different architects are setup, but still, there may be a possibility that this information can be hacked in case the IP address is accessible easily.Some can also use it to increase their websites rank. It can also be used to keep a check on any kind of highly confidential data leakage. For example, organizations can use a proxy to observe the traffic of its employees to get the work efficiently done. It must be configured to the specific application such as HTTPs or FTP. Protects true host identity: In this method, outgoing traffic appears to come from the proxy server rather than internet navigation.It makes the original IP address of the node remains hidden while accessing data from that server. Internet Client and Internet resources: For internet clients, Proxy servers also act as a shield for an internal network against the request coming from a client to access the data stored on the server.The proxy server also prevents the identification of the client’s IP address when the client makes any request is made to any other servers. The basic purpose of Proxy servers is to protect the direct connection of Internet clients and internet resources. There are different types of proxy servers available that are put into use according to the purpose of a request made by the clients to the servers. Proxy server refers to a server that acts as an intermediary between the request made by clients, and a particular server for some services or requests for some resources.
