In the operation process of the prepress publishing system, the server system mainly uses a file server. The files stored in the server include various image files, typesetting files, sample files, large sample files, layout package files, and other limited formats. The extension is basically fixed. Mainly include: *.tif, *.eps, *.jpg, *.pic, *.fit, *.pub, *.txt, *.ps, *.psf, *.zip, etc. The above file types are allowed Into the server; At the same time, there are still some file types should not be written in the server, such as: *.eml (virus file), *.exe (executable program), *.mbx (mail file), *.htm , *.html (web page files), *.wav, *.mpg (multimedia files), these non-prepress publishing system typography process files or intermediate files will not only take up a lot of hard disk space, but also have a server virus infection The hidden danger. To prevent non-prepress publishing system process files from being written to the server, file server protection software can be used to protect the server.
1. How File Server Protection Software Works
In the Windows operating system, before reading and writing files, a system message is triggered. By intercepting this message, the server file can be read and written. The server file protection software controls the reading and writing of files in the server by intercepting the read and write messages of the files in the server in advance. By setting the match between the file name and the extension, write-protection and write-in of different types of files are realized.
2. File server protection software features and operations
The file server protects the file protection program. It uses the WinNT system service to run. After the installation is complete, an automatically-started file protection service is added to the WinNT service. By filtering the server file, the file is written to the server. Into the control. Users can customize the file extensions that are forbidden to write to the server. Once an extension is set, files with these extensions will not be allowed to write to the server. For example, if the user-defined write-protected file includes a file with the extension eml, the virus generated by Nimda will not be written to the hard disk.
The specific functions and operations of the file server protection software are:
(1) The system service is used to run. After the program is automatically started and run, a program icon will appear in the lower right corner of the desktop. Right click can be used to set parameters and run and stop the service.
(2) The program icon is displayed differently when the program is in a different state. For example, the icon displayed when the service is running is green, and the icon displayed when the service is suspended is red.
(3) It has a file extension list function that prohibits writing to the server. File extensions that prohibit writing to server files may or may not include folder path names. Folder paths that do not include all files of this type are prohibited from writing to the hard disk. Include folder path names to indicate only corresponding All files of this type under the folder are forbidden to write.
(4) The system default rule is to allow all files to be written. If the file written to the server is the same as the setting that prohibits writing files, it will be prohibited from writing to the server. Otherwise, writing is allowed.
(5) Only the system administrator can set the parameters of the software. Non-administrators cannot modify the parameters.
