Secure Remote Access

Key points of implementing secure remote access

In today’s era, the Industrial Internet of Things has completely changed the way of working of the OEM business model. The overall equipment effectiveness business model is extremely efficient and beneficial for the organizations. Several IoT establishments require monitoring of their machines closely in the fields. Hence, one of the best options to achieve this goal is to opt for the remote access option. Here we have discussed the factors that influence the remote access solutions for the industry.

Nowadays, there are several remote access solutions like remote desktop connection (RDC) and virtual private network (VPN) that are rendering secured and safe remote access to the systems of organizations. Therefore, it is very important for an organization to implement remote access to its workers. Below are some of the key points of implementing secure remote access of the machines to the employees.

1) The lengthy process of Setup that requires expertise in the IT field

There are various parameters which are needed to be executed before the implementation of the remote access. This will render great help in exchanging the data and the authentication keys. The process of establishing the RDC and VPN is time-consuming, complex and difficult, plus it also demands great expertise in the IT field.

2) It requires compromise with the machine accessibility

The VPN application demands a good VPN server that can render a static public IP address.The network ports are also needed to configure and permit the outbound and inbound traffic.Numerous IT departments are unwilling to implement the required changes in the network of their organization.These changes can create some network vulnerabilities and network deficiencies.                                                                          

3) Increases complexity and cost of security of remote connections                                                                     

The VPN connections between the machine operators and builders are generally established from site-to-site. This type of connectivity renders remote access of machine builders to all the local devices. The only way to eradicate this problem is to build a separate end-to-end connection of a VPN. This connection is expensive, complicated and has a huge maintenance cost.

The RDC connections are also complicated and require a separate computing system to plant the public network. In order to lessen these resources, one requires human effort and a handsome setup cost.

4) VPN Security is complex and hard         

One of the best ways to achieve higher VPN security is that one must have different pre-shared keys or X.509 certificates for every VPN tunnel. If the number of VPN connections is few, then the requirement of keys or certificates is also less. VPN security is hard to manage and demands special expertise in the IT field.

5) The flexibility and scalability of the VPN is costly                    

The VPN servers have a limitation in supporting the VPN tunnels. Large businesses require more number of machines and devices. It also demands more number of support engineers. If the number of VPN connections exceeds the server capabilities, then the machine builder will have to install a new VPN server which is a time-consuming process.


Due to all these restrictions and limitations, the RDC and VPN based remote access solutions are complicated and hence, the manufacturers are demanding an easy, flexible, scalable and reliable solution that can support their organization.
