Hong Kong VPN implementation comprises several components that you should know of. In this article, we will look into detail in authentication component and its types which is the most crucial element of Hong Kong VPN implementation. Read on to learn more about this module, its 2 different type and various applications used today.Authentication
It is understandable that a concern you may have is to somehow verify a user’s or device’s identity before enabling it to establish a Hong Kong Virtual Private Network connection to your certain network. There are 2 typical categories of authentication that you should know of comprehensively:
- User
- Device
Device Authentication
Device authentication enables you to fully control Hong Kong VPN access to your network depending on authentication information that a remote Virtual Private Network device offers. Generally speaking, this is one of the following 2 kinds of authentication:
- Pre-shared keys or key
- Digital certificate or signature
Pre-shared keys are generally used in smaller Hong Kong Virtual Private Network environments. One or more keys is usually configured and used for the purpose of authenticating the identity of a device. You might be pleased to know that it is rather simple to set up pre-shared key authentication. Most of the administrators prefer its usage rather than digital certificates or signatures, which need a lot more work to set up. Pre-shared key require you to configure a key manually on every device that will participate with the Hong Kong VPN connectivity.
Given the configuration amount though, pre-shared keys have one primary disadvantage: and that is that they do not scale well. For instance, assume that you have nine sites currently with a router at every site, where pre-shared key is used for authentication of device and the VPN L2L design is completely meshed between the distinct sites. You add an extra site. This needs you to add 9 keys to the router at the brand new site and then set up key information on routers at the other 9 sites. So including more sites makes management and addition of authentication keys too complicated.
Digital Certificates
Normally these are used for device authentication in big Hong Kong VPN deployments. Certificates centralized by a common authority, called certificate authority render removing and adding Hong Kong VPN devices an easy process. Any time a device is included to the Hong Kong VPN topology, a new certificate gets generated for the particular device, containing the authentication information for that device. This is stored by the certificate authority.
Other Hong Kong VPN devices can gain access the certificate authority to validate identity of another device. As you probably can see at this point, a device does not have to locally store the authentical information of other devices. This information is centralized and held by certificate authority. That said, the primary con of the usage of certificates is that the initial deployment and setup of certificate services can be rather work-intensive.
User Authentication
Majority of the Hong Kong VPN implementations add an extra layer of authentication, that is referred to as user authentication. This is used to verify whether or not a Hong Kong VPN connection is enabled by a user using a particular device. Normally this is often employed in remote access Hong Kong VPNs. In some of the cases, depending on the implementation type of the VPN, the Hong Kong VPN may perform both user and device authentication.
When it comes to user authentication, the user has to generate a password and a username. This password may be a static password or a single time password (via the usage of token cards).
Bottom Line
Authentication is the crux of most VPN implementations such as the ExpressVPN Hong Kong. You should know well about both types of authentication as described in this article so that you know which one applies to your case.
