Tools Used for the Protection of Data Security and Privacy
- Virtual Private Network (VPN).
- Proxy Servers.
Let us get into a little more detail about these topics.
Virtual Private Network (VPN)
It is a collaborative mechanism and program that helps in creating a safe, encrypted connection over a less secure data communication channel. Its security measures ensure that the data's integrity, confidentiality, and user authentication are maintained. List of some popular VPNs are:
- Hotspot Shield.
These programs are installed in the system to maintain privacy with the help of security procedures and tunneling protocols incorporated in these VPNs.
There are different types of VPNs, such as:
- Remote accessing VPNs.
- Site-to-Site VPNs.
- Hardware VPNs.
- Mobile VPNs.
- Dynamic Multipoint VPNs.
Proxy Servers are also used for security purposes as they act as an entrance between the user and the internet. It acts as an intermediary server that separates end-users from directly accessing any website they surf. There are various functionalities of a proxy server working, providing security and privacy, and all of these depend on the use case, employee requirements, or company policy.
So How It Works?
When you are browsing through a proxy server, all of your internet traffic streams through that proxy server to that particular address you've requested, and the response comes back to that same proxy server. The proxy server then moves ahead of those response data received from that particular website to the user who is using that proxy server.
