The following is a brief list of security points. before checking these security points, ensure that the IIS server is online. If the following security points are violated, the Administrator may need to understand the security hazards that should occur to known security problems in the security document.

Ii. Restrict System Access
Before entering the Linux system, all users need to log on, that is, users need to enter the user account and password. Only after they pass system verification can users enter the system.
Like other Unix operating systems, Linux typically stores passwords in the/etc/pas

Nagios is an open-source free network monitoring tool that can effectively monitor the status of Windows, Linux and Unix hosts, network settings such as vswitches and routers, and printers. If the system or service status is abnormal, an email or text message alert will be sent immediately to the website O M personnel. After the status is restored, a normal email or text message notification will be sent.

To build a secure IIS server, you must fully consider the security issues during installation.
1. Do not install IIS on the system partition.
2. Modify the
portal for hackers. For example, hackers can use the finger service to find users' phones, directories, and other important information. Therefore, many Linux systems cancel all or partially cancel these services to enhance system security.
In addition to setting system service items using/etc/Inetd. conf, inetd also uses the/etc/services file to find the ports used by various services. Therefore, you must carefully check the port settings in the file to avoid security vulnerabilities.

In Linux, there are two different service-type states: one is a service that is executed only when necessary, such as the finger service, and the other is a service that is continuously executed and never paused. This type of service starts to run when the system starts. Therefore, you cannot stop the service by modifying inetd, but you can only modify/etc/rc. d/rc [n]. d/file or use Runleveleditor to modify it.
