Server security has always been closely concerned about the webmasters. When we get the server, we should reinforce the server system as soon as possible to protect the stability and security of the server. Recently, some webmasters are not clear after buying an American independent server. How to make system security reinforcement, let's take a look at the specific method:

　　1. Monitor the CPU status of the American independent server

　　The malware of the US server Linux system is generally mining. Once the American independent server is minitted, the CPU's occupation rate will be very high. Therefore, American independent server managers need to monitor the CPU status of the American independent server in real time.

　　2. Check the /root/.ssh/ directory of the American independent server

　　The US server Linux system avoids the phenomenon of SSH weak passwords, needs to be changed to complex passwords, and checks whether there is any suspicious Authorized_key cache public key in the US server /root/.ssh/ directory.

　　3. Check the timing task of the system

　　The timing task is a common attack method for US server Linux system malware, so American independent server managers need to check whether the system has suspicious timing tasks.

　　4. Check the web program regularly

　　American independent server managers need to regularly check whether there are vulnerabilities in the Web program, and pay special attention to RCE vulnerabilities such as Redis's unauthorized access.
