Automatic deployment method for improving remote login safety of elastic cloud host

Abstract

The automatic deployment method for improving the remote login safety of the elastic cloud host comprises the following steps that S1, a PC end initiates a login request to a system, a remote access processing module checks whether a port is open or not, if yes, the next step is executed, If not, a data packet is discarded, and the request is ended; S2, the remote access processing module checks whether the IP of the PC end is in a white list or not, if yes, the next step is executed, otherwise, the data packet is discarded, and the request is ended; s3, the remote access processing module informs the PC that the available authentication protocol is only the secret key; s4, the PC terminal sends the user name and the secret key, and the remote access processing module checks whether the private key and the public key are paired or not and carries out judgment; s501, pairing the private key with the public key, and establishing connection between the PC terminal and the cloud host; andS502, if the private key is not matched with the public key, the remote access processing module informs the PC of login failure and returns to the step S4. According to the method, safety reinforcement is triggered every time a new cloud host is created successfully, the application is wide, and the expansibility is high.

Description

technical field [0001] The invention relates to an automatic deployment method for improving the remote login security of an elastic cloud host, and belongs to the technical field of cloud hosts. Background technique [0002] Elastic cloud host is a cloud computing service that can be obtained on demand and flexibly configured. It can help users create a stable, highly reliable, efficient and low-cost application deployment environment. Most of these environments are generated through different Linux system images, such as Centos, Ubuntu, etc. When installing these images, the lightest minimal mode will be used to reduce unnecessary overhead. Finally, users can access them through remote tools such as Xshell and SecureCRT These cloud hosts. [0003] If the security of these cloud hosts is not improved, once they are opened to the public network environment, they will be extremely easy to be attacked. In addition, when a cloud host in the intranet is invaded, the security o...

Problems solved by technology

[0003] If the security of these cloud hosts is not improved, once they are opened to the public network environment, they are extremely easy to be attacked

In addition, when a cloud host in the intranet is invaded, the security of other cloud hosts cannot be guaranteed

In order to provide users with a safe and reliable remote login environment, cloud host administrators or cloud host users need to separately strengthen the security of each newly created cloud host, so that the mutual login between cloud hosts is isolated, and a large number of repeated labor, time consuming
