One of the more useful tools for network technicians, particularly those attempting to set up a secure network on a time, is to use a secure shell service to browse the internet using both encryption and a proxy. Many systems can be rigged to use a secure shell, and a common example is the native ability of Linux systems to set up a proxy connection without a subscription.
For a Windows network, it is often necessary to pay for additional software to use a high-quality proxy or else install software that helps to create an encrypted connection with the broader internet. It is possible to set up a proxy using an external web service as is provided by network security companies or else to set up a private encrypted connection called a terminal proxy.
The proxy is arranged in the terminal of a system. This ability is native especially to Linux systems where a proxy connection can be achieved by rigging the network setting the right way using script commands in the Bash shell. A terminal proxy can also be set up in the network station that controls the traffic for an entire local area network.
A proxy connection or the ability to use an encrypted connection is not unique to network software and can easily be achieved by any regular computer using either the right internet configuration or service. Some browsers come with dedicated privacy software that connects to a VPN or encrypted network controlled by the service.
The setup for a network tends to be much more sophisticated because it is necessary to monitor both the traffic between computers inside the network as well as data entering and exiting the network from the internet. Since networks are more visible and are more likely targets for hackers, it becomes important to conceal a network as well as to monitor packages in order to prevent malware and leaks.
The advantage of using any form of encryption is that it conceals traffic. It is hard for a sniffer to determine what packages are being sent and the address of the sender and receiver. Encryption is like wearing a cloak on the web. The requests are sent to an intermediary device, which is the actual proxy service, and this machine requests data from the web on behalf of the client machine.
A proxy hides the requester in several different ways, which is also behind a company firewall. Another advantage of using a proxy is that all traffic can be monitored. The computer in the IT closet is sort of like a proxy and it has the power to record all web transactions. A third party service does a much better job and has very powerful computers that can sniff packages for malware.
