Do you want to stay secure on web? VPNs could be your go-to option in this regard as it adds an extra layer of security to your online surfing. VPNs are one of the best ways to avert many things – from ISPs logging the user activity over internet to a range of other network exposures. Hence, it is crucial to ascertain that a VPN is operating the way it should be, while its usage. They, however, can be subjected to false marketing.
Some VPNs claim that they can encrypt data only for users to discover that when the VPN is turned on, their network traffic is not encrypted. To verify that, packet analyzers like Wireshark can be employed. Additionally, this handy guide will help the readers to properly determine the working of VPN.
Packet analyzers – also known as packet sniffers – are tools to determine network related issues. While packet analyzers are used for finding solutions to network problems by system administrators and technicians, they are also, at times, used to gather user passwords or/and traffic by cybercriminals.
Whether they are used to determine network intrusions or troubleshoot network related issues, they can be exceptionally useful either way. A packet analyzer, for instance, is an effective tool for a technician or a system administrator used to determine the speed which is slower than normal. Packet analyzers can also be a great help for businesses to monitor their network activity to ensure that productivity remains up to the mark along with helping individual users to keep their networks secure.
Packet analyzers can be employed with VPNs. From validating the VPN’s encryption to sniffing network traffic, a packet analyzer has a wide range of uses.
While VPNs are one of the sure-fire ways to ensure digital privacy, they may also be employed for things such as gaining access to blocked websites or other restricted content in the country. However, it is quite unfortunate that the hunt of finding ‘A grade’ VPN provider is not always an easy task.
A user always has that urge to confirm if their choice is working the way it should – which means a user wants to confirm about their connection’s genuine encoding. If it fails to encrypt the data, the purpose of VPN crushes down. But, this is when Wireshark comes to the rescue.
It is a packet sniffer that captures network packets and displays them in detail for the user. Its usage ranges from troubleshooting problems to determine security vulnerabilities. But, most frequently, it is used by network security engineers, administrators, developers and even laymen. Unfortunately, Wireshark can also be used by hackers, looking to break into systems by sniffing data, network traffic and amassing passwords and other sensitive data.
When Wireshark is paired with a VPN, it can be ensured that a connection is encrypted and operating the way it should. A Wireshark may also be employed to gather traffic from VPN tunnel and user network.
Gone are the days when heavy pockets were needed to buy these packet analyzers. Thankfully, it is not the case anymore as Wireshark is free to use. It allows all users access to its features as a whole free software. On downloading it, users are able to use the full version of it.
Using knives are legal. If someone uses it as a weapon, it turns out to be illegal. Same is the case with Wireshark. It is legal but becomes illegal when used for an illegal purpose such as monitoring a network that one does not have permission to monitor. Apart from that, it is absolutely legal to use this software and analyze the network traffic.
Along with determining security vulnerabilities and troubleshooting network-related issues, it may also be employed to mug up network protocol internals or repair protocol implementations. Intrinsically, there are hundreds of protocols supported by this software.
If it does not support any protocol, they offer a “How to Edit” page that gives guidelines on adding the protocols. See their “Protocol Reference” page to get more information on the protocols supported by the software.
Despite the slight variations in the installing process, Wireshark can be installed on any working system including Windows/Linux and Mac.
Installing it on PC
There are a few things that will be required to set up a Wireshark VPN on PC:
After meeting the aforementioned requirements, one can proceed to the Wireshark VPN setup by following the steps below:
To install Wireshark on Mac, there are few things that are required before configuring the Wireshark VPN, just like Windows/Linux:
Once the requirements are met, one can proceed with the setup by following the steps mentioned below:
Mac, by default, only passes Wireshark VPN traffic that is necessary through a user Wireshark VPN. If someone wants to get all traffic passed through it, they will need to do a few additional steps:
Installing Wireshark is not a rocket science. Depending on the OS, the user simply need to download the corresponding file to execute it.
Installing it on Windows
Installing it on Linux
To install Wireshark on Linux, follow the instructions mentioned below:
Installing it on Mac
If issues arise during the above procedure, the following installation instructions can be followed:
Wireshark for Beginners
Using Wireshark can be a bit overpowering in the start due to its variety of uses. So, start out small as pairing it with a VPN is only the start of its capabilities. Fortunately, the initial steps are quite easy to master.
Sniff the Network Traffic through Wireshark
As mentioned earlier, one of the most common uses of Wireshark is to capture network packets by sniffing the network traffic. To verify the Wireshark VPN encryption, one needs a know-how of running a simple packet capture.
Verifying Wireshark VPN Encryption
To verify whether or not your VPN is encrypting data, Wireshark is one the most effective tools to use. The users are able to see with their own eyes whether Wireshark VPN is working the way it should or not by inspecting the data packets that their PC is receiving and sending. Also, it is also easy to do.
Following are a few steps that one needs to follow to confirm if their Wireshark is encrypting data:
Protecting Oneself from Packet Analyzers
Packet analyzers, as discussed above, are used to assist system administrators and network technicians to pinpoint network related problems. Unluckily, it does not mean that they cannot be abused by criminals for their illegal purposes. Hence, in order to stay safe online, consider the following tips to avoid packet sniffing:
To experience the ultimate security while being online, using a Wireshark VPN could be one of the best options to opt for. With a Wireshark VPN, one can surf the internet with total anonymity and also verify that VPN is actually encrypting the traffic. This is something that everyone needs to have in their systems to avoid putting their online safety and security at risk. So, without wasting another minute, install one of the best VPNs for Wireshark now and enjoy your digital privacy and security.
