A VPN enables you to connect to the internet in an code fashion. Encryption adds security and privacy, which is particularly significant when using public Wi-Fi. That ’ south because identity thieves and early cybercriminals much target populace Wi-Fi to steal the personal information you send and receive while on those types of networks .
It gets worse. You may think you ’ re using the free public Wi-Fi provided at an airport, hotel, or chocolate shop. But you may have logged on to a Wi-Fi network that only appears to be legitimate. But guess what ? A cybercriminal may have constructed the network to steal your data.
Reading: How does a VPN work?
A VPN allows you to use inherently non-private public Wi-Fi by creating an code tunnel through which your data is sent to a remote control waiter operated by your VPN service supplier. The VPN server then sends the datum to the site you ’ ra seeking to connect with, encrypted and safe from the prying eyes of identity thieves and other cybercriminals .
VPNs can sometimes slow your calculator ’ mho performance. That can happen if the VPN ’ sulfur servers are geographically aloof. For best performance, you might consider a VPN with servers located around the world. That way, your data can be routed through a closer location .
Some VPN services limit your custom. For case, they may limit the come of data you can send in a individual connection, over a period of time, or limit the speed of the data. This can be common with barren VPN services .
Types of VPN security protocols
VPNs use a assortment of different protocols. Older protocols, such as PPP and PPTP, are considered less secure. here are some of the types of security protocols .
- IP Security (IP Sec). Internet Protocol Security is a popular protocol that protects data through either a transport mode or a tunnel mode. Both provide encryption. It’s considered highly secure and is useful for securing inbound and outbound traffic. But it can require a lot of processing power, and that can affect device performance. Also, some of the security algorithms used in IPSec in the past have been hacked by cybercriminals. Newer versions of IPSec use stronger, more complex algorithms.
- Layer 2 Tunneling Protocol (L2TP)/IPSec. L2TP is a VPN protocol that doesn’t encrypt data by itself. That’s why it’s paired with IPSec encryption. One of its primary advantages? It’s available on most devices and operating systems and provides a high level of security. The downside? It can result in slower connections. That’s because it uses the double encapsulation process.
- Secure Sockets Layer (SSL) and Transport Layer Security (TLS). SSL was the encryption protocol VPNs generally used before 2015. It has evolved into TLS for encryption of data traveling to an SSL VPN server. One of the reasons that SSL has been largely replaced in VPNs is due to the large number of vulnerabilities discovered in the protocol.
- Point-to-Point Tunneling Protocol (PPTP). PPTP was the earliest of security protocols and first released in Windows 95. It’s fast, but that’s because the protocol provides a low level of encryption.
- Secure Shell (SSH). The SSH protocol isn’t considered especially user-friendly and doesn’t automatically encrypt all of your data. It’s more difficult for users to configure. Plus, fewer providers use this protocol, which limits your choices.
- Secure Socket Tunneling Protocol (SSTP). This Microsoft-developed protocol is considered highly secure and easy to use, but it doesn’t work as well on platforms other than Windows.
- Internet Key Exchange, Version 2 (IKEv2). This protocol is based upon IPSec. It’s considered quite secure and fast. One downside? It can be blocked by firewalls.
- Open VPN. This is perhaps the most popular VPN protocol. It combines high security and speed. Because it’s open source, numerous third parties maintain and update the technology. Norton uses this protocol for its VPN, Norton Secure VPN.
