The IP of the server can be disclosed, and it is very vulnerable to hacker attacks, such as DDoS attacks, viruses, etc. These behaviors are dedicated to consuming server space, affecting the normal operation of the server, and even paralyzing the network to which the server belongs. In order to better ensure the security of the Hong Kong server and try to prevent the Hong Kong server from being harmed by this kind of behavior, we can do the following:

1. Backup data and data information.

NTFS is a disk format supported by Microsoft's Windows NT core series of operating systems, and is especially designed for security features such as network and disk quotas and file encryption. In the NTFS system file, you can set access restrictions independently for each disk partition. Put your own sensitive information and service information on separate partitions. In this way, even if a hacker obtains the access control of the disk partition where your service file belongs through some means, he must try his best to strengthen the security policy of the system before he can further browse the sensitive information stored on other hard disks. Data information is backed up every day.

2. Close redundant service items.

The Windows system has many default services that are actually unnecessary, and can even be said to be dangerous, such as: the default shared resource remote registry file browsing (Remote RegistryService), many sensitive information in the system It is all written in the registry file, such as the data encryption login password of pcanywhere, etc.

3. Turn off redundant port numbers.

Some seemingly redundant port numbers can indeed disclose a lot of sensitive information of the operating system to hackers. For example, the IIS service opened by default on the windows 2012 server will inform the other party of your operating system windows 2012.

4. Open port 69.

The operating system is most likely a linux or unix system, because 69 is the port number used by the default tftp service under these operating systems. Further browsing of the port number can also return some information about the software and version on the server, which provides great help to hackers' intrusions. In addition, open ports are more likely to become a portal for hackers to enter the server

Fifth, do a good job of filtering TCP/IP port numbers. It is not only beneficial to avoid hacker attacks, but also helps to prevent viruses.

6. Server firewall maintenance.

The server firewall plays the role of a security guard in the protection system, which can largely protect illegal access from the Internet and mobile traffic attacks, such as denial of service attacks, etc.; the intrusion prevention system software acts as a monitor It monitors your server's import and export, and very intelligently filters out those browsers that contain intrusion and offensive features.
