Local server security when using cloud services

Local server security when using cloud services

Nowadays, the security of local servers when working with cloud services is becoming an increasingly pressing topic. This is explained not only by the spread of cloud technologies, but also by an increase in threats cybersecurity related to storing and processing data in the cloud.

Implementation of cyber protection in the “local network - cloud” infrastructure

For clarity of explanation, let's look at an example of connecting a home server to the Azure Arc service. To understand the essence of the problem, it is worth understanding what local servers and Azure Arc are. Local server — This is a physical or virtual device designed to process and store data within the local network of an organization or individual. Azure Arc is a service of the Microsoft Azure cloud platform that allows you to manage resources and applications not only in the cloud, but also on local servers.

Security in Azure Arc is implemented through several key concepts:

  • Private connection to Azure Arc. This approach allows you to provide a secure connection to the cloud without exposing access from the public network. This is achieved by using private endpoints that provide direct connection between the local server and Azure Arc, bypassing the Internet.
  • Authorized private networks. Ensures that data from Azure Arc-enabled servers is only accessible through designated, authorized private networks. This means that data can only be accessed from networks that have the appropriate permissions and authentication.
  • Preventing data leakage. To prevent data leakage from private networks, specific servers and resources are defined that are allowed to connect through private endpoints. Thus, data can only be transmitted through secure channels, eliminating the possibility of unauthorized access.

These concepts provide a high level of security when using Azure Arc, ensuring data confidentiality and integrity, and preventing unauthorized access and information leakage.

Connecting a local server to Azure Arc is done as follows:

  • Create a private endpoint for an Azure Arc scope. First, you need to create a private endpoint in your virtual network for the Azure Arc realm. A private endpoint provides a direct and secure connection between your on-premises server and Azure Arc services, bypassing the public internet. This allows you to avoid possible security threats related to data transfer over open networks.
  • Configure DNS to ensure proper name resolution. After you create a private endpoint, you need to configure DNS to ensure correct name resolution when accessing Azure services. This is important so that your on-premises server can identify and access Azure Arc resources by their names. This is typically done by creating a private DNS zone that maps Azure Arc resource names to their IP addresses in your virtual network.

>After completing these steps, your local server will be connected to Azure Arc through a secure and private connection, and your DNS settings will ensure correct name resolution to access Azure services without the need to use the public internet. This will ensure a high level of security and confidentiality when working with data and resources in the Azure cloud.

The role of VPN in protecting the local network - cloud infrastructure

In an infrastructure where cloud resources interact with local servers via Azure Arc, VPN technology is typically used at the border between the cloud and the local network. This means that a VPN connection is established between cloud network devices and the local router or firewall of an organization/individual.

This VPN connection ensures encrypted and secure data transfer between the Azure cloud environment and local servers via the Internet. At the same time, VPN gateways in the cloud and on the local side create virtual private network through which the exchange takes place information. This helps protect data from unauthorized access and ensure confidentiality when transmitted over an open network.

Private VPN server: strengthening your infrastructure

Private VPN server – an excellent candidate for strengthening the “cloud - local server” structure. It can be hosted on the local network side and used to establish a secure and encrypted connection between on-premises devices and cloud resources, including Azure Arc. Using a private VPN server in such a structure is more preferable for users who value control, security, performance and flexibility in providing a secure connection between their local resources and cloud services.

Buy a private VPN server on favorable terms simply through Private VPN server.
