Scenarios

Server Guard is designed to safeguard your servers and protect them from malicious attacks. Below are common Server Guard scenarios:

1. Server Security Monitoring Across Platforms

In case of different servers deployed on multiple platforms, same type of vulnerabilities are exposed on multiple servers. In case there is no centralized management to view the status of all the online servers across various platforms, manual effort is needed to mitigate individual threats for each of the servers.

Solution

Server Guard enables users to centralize security management to check the status as well as operate various functions collaboratively through its security console. This enhances security and gives you greater control over your servers. In the case of common vulnerabilities found in multiple servers, the patch repair can be applied at once from the Alibaba Cloud Security Console so that resources are not wasted on managing each infected server individually.

Architecture Description

The user accesses the Alibaba Cloud Security Console, where you can see the list of all online servers (servers are online only if the Server Guard agent is up and running). The service has its cloud control centre to analyze the vulnerabilities of the online servers through the agents and offer patches based on its existing library of attack models, malicious files/IPs and other such libraries.
