What is a VPN? A Virtual private network (VPNs) creates a secure connection between a remote computer and another network.
A Virtual private network (VPNs) creates a secure connection between a remote computer and another network. The connection itself is encapsulated and encrypted which provides a protected communications channel between the two points.
A VPN is becoming more crucial in today’s security-related society. Due to increasing safety concerns, the proportional use of these services is growing exponentially. This technology targets several critical aspects of our online experience: mainly privacy and security.
To better appreciate how VPNs work, we first need to understand how we navigate the internet. Any device connected to a network, whether public or private, is issued an IP address. An IP address is a set of four numbers called octets used to identify a particular device within that network. For instance, if we want to reach Google’s site, we send a request from our browser to a Google server over the internet. This request establishes a communication channel with the server to gather the information we are searching for.
In the image below, we can see the path that a browser request (from IP 18.104.22.168) takes to connect to Google (22.214.171.124). Each IP listed in this traceroute is a network device or node used to reach Google. Each node is a considered public connection from which a malicious actor can use to intercept our request. These attackers can track down these IP addresses and gather a great deal of sensitive information.
What is 2FA Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account.
