Although one condition could be tragic for one sector, it could also give another a blessing. Many people felt that the VPNs were threatened before the COVID-19 pandemic, but the opposite has happened. During a pandemic, VPNs have become an invaluable platform for remote workers, and we anticipate this to be the trend in the COVID-19 free world.
Although COVID-19 was reportedly started in 2019, it came to light early in 2020, and that was also when VPNs started to gain attention. The COVID 19 pandemic has contributed to a large-scale digital transition for many organizations and employees without shrinking terms.
The Conventional VPN Connection
Relatively few people were working in their homes before the pandemic, but now the situation has changed. Organizations have been imperative in searching for solutions to assist employees who need to use home computers and handheld devices to navigate corporate resources.
The conventional VPN uses an elaborate client model to create a stable tunnel between the consumer and company networks. This is the tunnel used by all communication networks.
However, you must think about this expense due to hair pinning. The model operates by allowing public cloud services to access the company site via the VPN tunnel, which then redirects access to the Internet-based cloud provider.
Corporations also realized the risk associated with open internet connections used by the employees in their home. There are no security checks and transmitting the data from home connection to the corporate servers could impose many online threats for invasion of company’s privacy.
Expected VPN technology advancements
Technological progress transcends all sectors, and VPN technology is not excluded. Although it seems to be enough for us, we must keep in mind that end device capability can be expanded, enabling the migration of more software-based VPN technologies into endpoints.
To make VPNs more user-friendly for both clients and network administrators, advancement has to be made possible in VPN technology. The network administrators are then able to monitor the administration of VPN through the central systems.
In reality, in a software environment, we do not need any hardware, but physical connections are still needed and, that means that we cannot do without a form of hardware. However, one way out is to install x86 computer systems to replace those dedicated devices and execute hardware-for-functions.
This would have to be at the edge of the network, where computational resources are spread. At present, we have nothing in mind to replace hardware, as only dedicated hardware can speed up the network core needs.
VPNs can also be converted into software-defined WAN products. This means that the connection is not dependent on and resolves the underlying physical network that can be wired, wireless, or cellular.
The function of emerging VPN systems must make efforts to utilize and transparently move between the advantages of multiple paths.
Expected VPN Security Advancements
Although we must applaud VPNs for their attempts to eliminate cyber-attacks, it is clear that they were not completely successful, as cyber-attacks have vastly increased. It is also valid to assume that more AI and machine learning instances can be used to improve these security functions’ performance without increasing the network or security administrator support.
For VPN paths not to become ineffectual if an endpoint is linked with internet-based resources like SaaS systems, IT experts must work together. When the VPN functions, it is considered essential that the endpoint first sends information to the VPN concentrator that then passes the data to the cloud-based SaaS application. This raises the latency of the network. The overhead network also rises within the VPN as encryption is also used by the SaaS application.
However, you can use split-tunneling to fix this discrepancy, but IT teams must choose the VPN termination point wisely to prevent creating a security hole. This can be accomplished by integration with intelligent DNS servers that allow split tunnels to specific sites managed by network or security administrators.
To ensure that your VPN system is extremely secured, you need to use the Zero-Trust model. Since you have to presume that endpoints are affected irrespective of their position, you won’t leave any information to chance.
The quality performance of networks has become a standard for measuring quality since the zero trust model launch with security components that include allowing listing and micro-segmentation by Forrester Research in 2010. VPNs must deploy automated methods to build and manage these security functions for sound cybersecurity practices.
