How to Enable VPN Two Factor Authentication Without Any Difficulties?Posted on 30th July 2021
Due to the widespread use of electronic resources in all spheres of human activity, the task of ensuring information security in such systems is acute. One of the main measures for data protection is to ensure reliable user authentication.
What Is Authentication?
Authentication is a process which purpose is to verify the identity of a user. The core authentication technology provides complete control over access to specific systems. It verifies whether the user’s data correspond to the credentials in the authorized user database. Users typically identify with an ID. The authentication is performed when a user provides credentials, such as a password that matches that user ID. The password is the main piece of information. Many users know how to use it. They understand how important it is to keep the password confidential.
After authentication, the user is usually authorized. It allows determining whether an object has access to a specific protected resource or system. The user can be easily authenticated but cannot access the resource if has no permission to access it. Some scholars think that the terms authorization and authentication are synonymous. Although they can often be implemented together, their basic functions are different.
Many modern business establishments use authentication to authenticate users who access their websites. Without proper security measures, user data can fall into the hands of fraudsters. Firms also often use authentication to control access to corporate networks and resources. In addition, authentication allows determining which servers are accessing the firm’s data. Organizations may use authentication to allow remote workers to securely access their programs and networks.
How Does Authentication Work?
During authentication, the data provided by users are compared with the data in the database of authorized users. If the credentials are appropriate and the authorized entity has the right to use this resource, the process ends, and the user receives access. The return of permissions and folders determines both the environment that the user sees and the amount of storage space for resources.
What Is Two-Factor Authentication?
Two-factor authentication makes authentication even more secure by adding an extra layer of security. 2FA requires the user to represent a second reliable authentication factor in addition to the existing password.
VPN Two Factor Authentication: Why Do You Need It?
Any organization, be it a trade, financial company, or government agency, is usually faced with the issue of information transfer between its affiliates. In this case, the transmitted data could not get to third parties except the final recipient. Not every company can afford to have a personal dedicated physical communication channel, even if the offices are hundreds of thousands of miles away.
In this case, the most appropriate option would be to use virtual private networks or VPN technology. It allows to easily connect multiple networks into one, even at different parts of the globe. This provides flexibility and high-speed data transfer, and most importantly, security in the exchange of information.
VPN technology is the common name for a technology that allows you to secure one or more network connections on top of other networks. There are many statements about VPN technology, and one of its main features is the use of the Internet as a backbone for transmitting IP traffic. VPNs are designed to connect the end-user to a dedicated network or a specific web resource. The structure of a VPN network includes WAN channels, secure protocols, and routers.
The Principle of Operation of the VPN
Special virtual dedicated channels are used to combine local networks into one virtual network. A tunneling mechanism is used to create such connections. The tunnel initiator encapsulates the packets of the local network in new IP packets, which contain in their header the address of the tunnel initiator and the address of the tunnel terminator. Upon receipt of such a packet, the end-user (tunneling terminator) performs the reverse process of decrypting the received packet.
In such a transfer, you must first consider the issues of confidentiality and integrity of data, which cannot be provided through tunneling. To achieve confidentiality in the transmission of information, it is necessary to use a certain encryption algorithm, and it must be similar for both the sender and the recipient. Only they must have information about what algorithm is used and have a key to encrypt and decrypt traffic. Encryption protocols can be different. It all depends on which tunneling protocol is supported by a particular VPN solution.
One of the important characteristics of VPN solutions is a range of supporting authentication protocols. Most popular products work according to standards using the public key. This means that it is possible to strengthen the protection of the virtual network with the appropriate authentication protocol. In this case, only specific users can access the protected channels.
Advantages of Using a VPN
Compared to conventional local area networks, VPN networks have several main advantages, which include:
- Security is one of the main factors and aspects of VPN services. After all, even if a third party has the opportunity to interfere with the VPN network and listen to the traffic transmitted over it, without the ability to decrypt it, all the information obtained will be a set of incomprehensible data. Without knowledge of the key, it is not possible to do. And the selection of the key can take more than one thousand years, and these factors may depend on the type of cipher, the length of the key;
- Economy – when using VPN networks in the enterprise, it is possible to partially limit the amount of intermediate equipment (routers, access servers, etc.) and consumables (cables, communication lines, and other technical means). And most importantly significantly reduce the cost of physical equipment and its maintenance. But without sacrificing any aspect of security, even if the user can connect to the network from anywhere in the world with only data to connect and a configured client to connect to the network via a private VPN channel.
The approach of using VPN networks is expedient nowadays because each authorized user has the opportunity to access the necessary data, network resources via the Internet. This makes the use of such technology competitive and relevant today. Such properties are difficult to achieve when using conventional, traditional private networks. And businesses that are willing and able to use and access network resources can sometimes have incompatible networks, which greatly complicates the process of setting up this type of network. This issue can be especially acute when a large number of organizations want to work together through one network.
Two-Factor Authentication for VPN Connections
To further improve the security of external connections to internal resources of the corporate network, it is recommended to strengthen the VPN connection with two-factor authentication. It is the security of your VPN connection. In this case, not only a username and password are required, but also an additional temporary one-time code generated by the token. Therefore, the user authentication process is a combination of several data. Among them are the data that the user knows and those that the user receives. Due to this, the user is protected from account theft and malware such as keyloggers, crackers.
Enabling VPN Two-Factor Authentication
The most popular way to enable two-factor authentication today is by using a dedicated app that generates one-time passwords. Such an application can be Google Authenticator or 1Password.
Usually, when you enable authentication, you will be asked to point the camera at a QR code or manually enter a sequence of characters. The application will save this secret sequence and use it to generate one-time codes.
Thus, no wonder that a two-factor authentication VPN is used by many users on the network today. Everything is very easy and simple. Just a few steps, and you will reliably protect your data online!
