VPN – virtual private networks, a local connection that is laid through an existing Internet connection. Thanks to the capabilities of the software, an encrypted channel is created for the exchange of information, which excludes any leaks, or interception of files by third parties – fraudsters, providers, or government agencies. Since the network is aimed at ensuring the confidentiality and security of the client, information arriving at the home ip will be automatically checked for malicious files and the connection point for the presence of security protocols of the required level. Using a VPN, you can protect important corporate, and personal information, and control access, both within the company and for remote work.
Why you should use a VPN
Ordinary users willingly install VPN for iPhone to bypass regional blocking and obtain information that is not available in a particular country or city. VPNs are popular with various companies and enterprises due to their ability to create a secure tunnel for transferring important data and remote work. Benefits for corporate clients:
- Savings on office rent, and related costs.
- You can attract experienced professionals living in other regions of the country.
- Employees can work from home without coming to the office, which will significantly increase the length of working hours.
- Secure, fast internet connection with the encrypted internal channel for corporate use.
A VPN connection is a one-stop solution for protecting personal, and internal corporate information for business owners who cannot afford the installation of expensive software. On the market for such a service, services are presented in various price categories, and there are good free and paid versions that differ in the set of functions and power levels. There are also easy-to-use services that ordinary employees and administrators can access, so the owner does not have to conduct special training or hire an employee to set up a VPN connection.
Protection of transmitted data
Data transfer security is ensured by encrypting the user’s real location. During the change, the client’s ip-address changes to any other, which allows you to mask the real location of the computer and secure the client from a physical point of view. Attackers will not be able to calculate the user’s location using an IP address – you can download and test one of the VPN programs for free, pick up any server, and verify the effectiveness of masking in practice. Networks make it possible to bypass blocking, and protect against attacks by the provider, and government agencies. The basic principles of data transmission protection are based on the creation of a separate encrypted channel, and authentication of the recipient and sender.
Channel encryption
The transfer of information on the Internet is carried out through unsecured channels, which often leads to the leakage of financial, and personal data of users. Such a connection between corporate networks and businesses is dangerous since any transmitted files can be intercepted and used at one’s own discretion. The risk of leaks increases if individual company centers are scattered across regions, most of the employees work remotely.
Once the VPN is connected, a point-to-point link is created between the two computers. Before information enters the tunnel, the data is encrypted by the service installed on the PC, decryption takes place after the data arrives on another computer or server. In practice, requests that are sent by the user are first sent to the VPN server in encrypted form and later transferred to external resources.
User identification
Since the channel that is created using a vpn connection looks like the transfer of information using directly connected wires, the files cannot be intercepted by the provider or a scammer. Also, the network will not send information if it cannot identify the user by the following criteria:
- The network address of the information source.
- The recipient’s IP address.
- Protocols installed on the server.
- The data or port number from which the data is being received or to which the data is being transmitted.
The formation of a connection and the transfer of files will be carried out only if the policy of protection, the security of the client, and the transmitted information are observed. For example, if in practice the user connects to a site that does not have a security protocol, the VPN connection will cross the transmission and alert the user to a possible threat.
How to control access with a VPN
A VPN connection is used by ordinary clients for personal purposes, to unlock or connect to resources in a confidential mode, and by companies for a secure corporate connection. With a remote access connection using virtual networks, the client connects to an isolated channel as if the computer is connected to the network through wires, not through the Internet. In practical application, a VPN connection client can use corporate resources and connect to a workplace remotely.
To control access, a secure connection is created between the main computer of the owner of the corporate network, the administrator, and the employees’ equipment. The main nuances of connection:
On the main server, through the functions of the server manager, the virtual network role is installed and configured on the main controller, it will serve as the main tunnel for remote connection of another computer
- Access for ordinary users is configured on the server. The “Server Manager” specifies the users who are allowed access to the network.
- On the client’s computer, the settings for connecting to the created channel are configured. Through the network control center, an IP is set for the connection, which corresponds to the virtual address of the main server, and keys for encryption are created.
- The employee’s equipment is connected via VPN by entering a name, and a user password.
- To connect to a remote workplace, specify the server IP address and credentials under which the employee is registered.
After the settings, when employees subsequently connect to the main service, the administrator or connection owner will be able to track the connection time and the IP address from which the connection request was received. In practice, using a virtual network, you can timely stop access if an unregistered computer connects to the tunnel, and restrict employee access to certain corporate information and files.
In addition to the corporate connection, employees can also connect to the workplace on a remote basis from anywhere. An employee will be able to use a home or public network, and send the necessary information to the main server, without fear of interception or fraud. Information will be transmitted in encrypted form, over a secure channel, which will minimize the risk of leakage.
