Enterprise application of VPN technology example analysis, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

VPN (Virtual Private Network)

Virtual private network (VPN), which encrypts data by establishing a private network on the public network, is more and more widely used in enterprises. There are many types of VPN, mainly to distinguish the types of VPN by protocol types, and it is also implemented in a variety of ways, such as servers, hardware and software.

At present, the most commonly used ones are: SSL-VPN, IPsec-VPN

The main features of SSL-VPN are as follows:

Adopt SSL protocol, between HTTP layer and TCP layer, use SSL protocol to encrypt and transmit data.

SSL-VP is connected to a certain application within the enterprise, but not the whole enterprise intranet, so it is more secure.

Internal network only needs to open port 443, session protection is powerful (automatically disconnected)

No need to change the policy of the internal firewall

IPSEC-VPN has the following characteristics:

The consumption of key negotiation between the two sides of the conversation is low.

Few programs need to be changed by the client

VPN network that is easy to build

Today, let's introduce how to configure IPSEC transport mode VPN on Windows systems.

Open Management tool-Local Security Settings-IP Security Policy

Right-click in the right margin to create a new policy

Enter a name and related description

Just pay attention to the mark above.

Next step-finish-check Edit Properties

Click add-next

Select the network type according to the demand. Next step.

Click add-enter Rule name-add-next

Select source address (you can also enter it manually) next

Enter the destination address (drop-down to choose from)

Protocol Typ

Select the port number (or any port)

Click finish

Check the next step of the new rule

Add using the wizard

Set the new rule name next

Select operation behavior

Check Edit Properties-finish

Custom settings-selection algorithm and encryption algorithm

Check the rule next step

Use pre-shared key for authentication (enter shared key) next step

A VPN policy is generated on the right side of the IP security policy.

Right-click the policy name-assign-complete the policy assignment

At this point, the whole configuration is over and over, and the system configuration of the opposite end user is the same as that mentioned above. After the configuration of both ends is completed, the data can be encrypted and transmitted by IPSEC-VPN through the pre-shared key.

After reading the above, have you mastered the method of case analysis of enterprise application VPN technology? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
