VPN

Today VPN service is in trandint in use. A VPN stands for Virtual Private Network. It is a service that can use to access the web safely and privately by routing your connection through a  server and hiding your online actions.

In addition, Virtual Private Network is a connection method used to add security and privacy to different private & public networks, For example, WiFi Hotspots and the Internet.

VPN Service is mostly used by corporations to protect sensitive data.

How does the VPN service correctly work?

Firstly, you start the VPN client (software) from your VPN services.

This software encrypts your all data before your Internet Service Provider, or the coffee shop WiFi provider sees it.

After that, all the data goes to the VPN and from the VPN server to your online destination. Anything from your website to a video sharing website to a search engine.

The online destination sees your data as coming from the VPN Service, and its location does not come from your computer and your location.

Though it is the standard, this sort of connection has some flaws. All of your data is out there in the open, and any interested party can peek at what you’re sending.

The internet is a collection of servers responsible for storing different websites and serving them to anyone who wants to view and learn them.

Those all the servers talk with each and other all the time, also including sharing your data to let you browse a page ultimately. Great for you to be able to surf, but that is not great for privacy.

Going online on a website is like taking a commercial airline flight. The ticket agent baggage handlers all security personnel and flight attendants all need pieces of data to get you routed between cities. A similar exchange of information happens on the websites

If it is just a fun website that you are looking at, then no need to worry. It does not matter if someone sees your data. But if it is online banking, business emails, or anything else that’s a bit very sensitive. It has a different story.

When you are using a VPN Service. Your data is encrypted because you’re using their app goes in encrypted form to your ISP then to the VPN server.

The VPN server works like a third party that connects to the website on your behalf. This solves the privacy and security problem for us in a couple of ways.

The destination website sees these servers as the traffic origin, not you.

No one can identify you or your computer as the source of the data, nor what you are doing what websites you are visiting, what data you are transferring, etc.

Your data is encrypted so even if someone does look at what you are sending. They only see encrypted information and not raw data.

VPN protocols

The VPN protocols guarantee an appropriate level of security to connect with systems when the underlying network infrastructure alone cannot provide it.

There are several different protocols use to secure and encrypt users and corporate data. Let’s talk about some important and most common VPN protocols.

  1. OpenVPN: OpenVPN is an open source of VPN protocol.
  2. L2TP/IPSec: Layer 2 Tunnel Protocol/IP security is another popular VPN protocol.
  3. SSTP: Secure Socket Tunneling Protocol is a very popular VPN protocol.
  4. IKEv2: (Internet Key Exchange version 2)
  5. PPTP: Point-To-Point Tunneling Protocol

Security limitations of VPN

 

In this word, any device that accesses an isolated network through a VPN presents a risk of bringing malware to that network environment unless.

There is a requirement in the VPN connection process to assesses the state of the connecting device. Without an inspection to determine whether the connecting device complies with an organization’s security policies, attackers with stolen credentials can access network resources, including switches and routers.

The addition of SDP programming gives medium and large organizations. The ability to use a zero trust model for access to both on-premises and cloud network environments.
