security performance based questions

All the code in this article is based on the CentOS 6.4 operating system as an example. It should be applicable in version 6.x. If other versions are different in the command path, the idea is the same. This article can also be called: CentOS operating system full settings and optimization. After the CentOS system is installed, it is recommended that you do not rush to perform these installation settings and optimization, because early operations will

example. The main role of this item is to set up for security checks, that is, the page in the system registration process. There is a key session variable for menu generation based on the permissions of the currently logged on user ("Yhqx"), which is generated during a security review that is to be described later, until the user exits the system or the session
