How does a VPN work?

A VPN can hide data about your IP address and allow you to go on-line anonymously. How ? A VPN encrypts your communications on whatever device you ’ ra using, including call, laptop, or pad. It sends your data through a secure burrow to the VPN service supplier ’ s servers. Your data is encrypted and rerouted to whatever web site you ’ re trying to reach. The internet is not a very private rate. If you use public Wi-Fi networks for things like shopping and bank, you could have your on-line privacy invaded, your data taken, and your identity stolen. Using a virtual secret network — VPN, for short-circuit — can help .

VPN basics

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.

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 .

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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. 
  6. 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.
  7. 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.
  8. 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.

Why do I need a VPN?

For case, consider the dangers of using public Wi-Fi. Cybercriminals may be able to access personal data you send and receive, evening if the network you ’ re on is password-protected. In some cases, the data can be used to commit identity larceny or to access your on-line accounts. A VPN can help protect your data in two ways. For one, it can help prevent data from being stolen through a bogus public Wi-Fi set up by a cybercriminal. It can besides help protect data being passed on a legitimate populace Wi-Fi that ’ s been hacked by a cybercriminal .
What ’ s more, your internet searches on a VPN stay individual. This is important because your Internet Service Provider, or ISP, is permitted to sell your browsing history to third gear parties. And while third parties may entirely be using this information to target you for advertising, there are other risks .
For exercise, your information could be accessed in a datum breach. Criminals might use the exposed information to create spear-phishing emails. If you click on one of these bogus emails, you could become a victim of identity larceny or a ransomware cyberattack .
Spear-phishing emails are often specifically tailored to your interests. They attempt to lure you into clicking on links containing a variety of malware. That includes keystroke logging malware, which can lead to identity larceny, or ransomware that can lock and encrypt your computer ’ s data, making it inaccessible to you unless you pay a ransom.

The enhance privacy provided by a VPN is besides a argue for considering the manipulation of a VPN for your devices at home even when you are not on populace Wi-Fi .
In short, here ’ s what the benefits of a VPN search like. VPNs protect by :

  1. Encrypting your web activity.
  2. Hiding your physical location.
  3. Adding to your web anonymity.
  4. Securing the personal information you send and receive while on public Wi-Fi.
  5. Protecting your online data from being used to make you vulnerable to spear-phishing.

What is a no-log VPN?

Norton Secure VPN collects subscriber information for communication purposes, mobile device data, and aggregate bandwidth custom. It ’ s important to note that Norton Secure VPN does not log information about where you go on the internet .
