What Is VPN? | How To Use VPN?

A virtual private network is a technology that creates a safe and encrypted connection over a less secure network, such as the internet. Applications running across the VPN may therefore benefit from the functionality, security, and management of the private network. They are used to securely connect geographically separated offices of an organization, creating one cohesive network. Individual Internet users may secure their transactions with a VPN, to circumvent geo restrictions and censorship, or to connect to proxy servers for the purpose of protecting personal identity and location.

VPN Protocols:

 IP security (IPsec)
Secure Sockets Layer (SSL) and Transport Layer Security (TLS)
Point-To-Point Tunneling Protocol (PPTP)
Layer 2 Tunneling Protocol (L2TP)
Open VPN

Privacy and Security:

VPNs cannot make online connections completely anonymous, but they can usually increase privacy and security. A VPN secures the private network, using encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

This can lead to you losing valuable data, such as passwords. It’s also interesting to note that while phishing remains a major danger online, a VPN can help protect you against malware or con tricks when web browsing.

The VPN security model provides:
  1. Message integrity to detect any instances of tampering with transmitted messages.
  2. Sender authentication to prevent unauthorized users from accessing the VPN.

Why you need a VPN:

That’s why a virtual private network, better known as a VPN, is a must for anyone worried about online security and privacy. Unless you were logged into a private WiFi network that required a password, any data transmitted during your online session was likely vulnerable to eavesdropping by strangers using the same network.

Surfing the Web or transacting on an unsecured Wi-Fi network means you’re placing your private information and anonymity at risk.

Site to Site VPN:

A site to site VPN uses a gateway device to connect the entire network in one location to the network in another usually a small branch connecting to a data center. It is also common to use carrier MPLS clouds, rather than the public internet, as the transport for site-to-site VPNs.
