Nothing could be impossible in the world of the internet as of now. If your concern about security and privacy the most, then VPN could be the best choice of protection. Still, there arises a doubt, can a VPN be tracked? Probably the answer may be yes or no depending on the degree of encryption layers and subsequent securities. If you want to keep your data secure, the only option is too supine the internet and which is impractical. But there are ways to keep on adding security to your networks like Tor over VPN and much more.
Can a VPN be tracked by Police or Government Agencies?
A VPN is always best in providing security to some extent. Using a VPN can be easily spotted by your internet providers. But a single piece of trace left can make your ISP track your IP address by knowing which server you are connecting. So, it is up to your VPN service providers who make complicated techniques to deal with the track.
Some of the VPN providers use higher-level strategies to hide information and make it difficult to find. These techniques may overcome VPN restrictions and provide access to blocked content.
The question here is how can they track while using a VPN if several levels of security layers have been provided.
How can a VPN be traced?
VPNs can be tracked via three ways and commences from easy to the most challenging methods. The explanation may be as follows.
1. IP Address
The easiest way of identifying and tracking the particular device. The server that connects you to the web pages or a specific website is known to both the ISP and the site you connect. The look of the IP address is not much delicate for an ISP to pick up. ISP could always maintain the list of IP addresses of most popular VPN service providers.
2. Port Number
Every protocol uses a specific and unique port number. When you are connecting the VPN to a particular service provider, the IP address along with the port number is delivered to the specific server. So by identifying the port number, which relates to the particular protocols, it is easy to say that a device is utilizing a VPN.
3. Deep Packet Inspection
The technique is quite a high level used to monitor and recognize the site traffic. This kind of inspection is used in china and other VPN restricted countries to detect traffic arriving in and moving out of the country. It is a firewall-based aspect to prohibit the use of a VPN. It executes higher level algorithms to inspect every packet broadcasted over the air. You can detect every kind of traffic via DPI and is the most modest tactic of inspection.
But VPN providers use complicated techniques to mask the VPN usage and making it a simple one. This advanced technique may restrict the VPN block and paves the way to access the restricted content.
Many authorized organizations, police, and ISP use DPI to detect a VPN. The websites could track you by using cookies, fingerprinting of the browser, DNS leaks, VPN logs, and transactions. So, it is necessary to check whether your VPN service offers and provides complicated techniques to detect the VPN.
