Data servers, application servers or other important components of the infrastructure should not be freely accessible directly from the internet. This is also the reason why IT support companies use VPN service for access to off-site infrastructure.

Most of the time, ports are left open on the internet and they can be easily exploited by hackers

Servers checked over 40,000 systems, belonging to both companies and public institutions. Most services exposed on the Internet are MySQL database servers, followed by the Remote Desktop Connections service. To easily eliminate this vulnerability, it is recommended to use VPN connections.

Following the tests performed in Universities, it was found that over 51.9 of the servers could be accessed directly from the Internet.

How does a VPN connection help in this context

VPN connections allow users to access infrastructure resources as if they were physically present at the location. In this case, the VPN offers an additional level of security, as the connection to it is made with user and password, plus access key or certificate.

• Traffic through the VPN tunnel is encrypted, so it cannot be intercepted at the router level by malicious people. In addition to the connection data to the application server or database, it is necessary to enter the connection data to the VPN.
• When we talk about security, we also refer to a positive form of paranoia. A good policy is to restrict access as much as possible and to allow access to certain services only when needed, using secure ways.
• A VPN (Virtual Private Network) allows you to create a secure connection to another network via the Internet. VPNs can be used to access restricted sites or content in a certain area, in this case, to hide searches on public WiFi networks by less well-meaning people and to increase the safety of internet browsing.

Even though VPNs were created to increase the security of corporate networks, nowadays even the home user can enjoy the benefits that a VPN brings in the online environment. Also, most VPNs are now compatible with all operating systems, which means you can even install a VPN on your mobile phone or tablet.

What Nord VPN Offers

NordVPN offers cyber security and anonymity for every user. The company offers servers worldwide, including the USA, New Zealand and the United Kingdom. Dedicated servers also provide a single user connection, so there is no possibility of losing data. NordVPN offers double encryption.

Conclusion

A disadvantage is that about 30% of the bandwidth is lost, which means that the internet will go much harder. And the fact that you are forced to set different protocols if you connect several devices to the same server will make the setting difficult. However, NordVPN provides 24/7 technical support, so someone will help you make these settings.
