I currently have 5 websites, all using the DEDECMS system for the foundation of the station, the advantages of this procedure need not be said, just once in the maintenance site when the site was hung black chain, or jump to other domain names and other phenomena let me at one time very distressed, but fortunately later all resolved, Here for the webmaster who just used the DEDECMS system to analyze the following Web site was hanging horse and black chain reasons.

1 when the station is under construction due to the carelessness of the webmaster did not change dedecms default path, such as DEDECMS's default background path is the URL/dede/login.php. This path makes it easy for some hackers to find a login address to decrypt and attack and steal database information. So be sure to set the default path in the background, and change the Dede to another way. In order to ensure the security of the background, to avoid the code through the background to hang a Trojan horse.

2 in the background of the login address is originally a verification code, many webmaster to save trouble directly to the login need to verify the code to turn off, because the basic parameters in the background has this function. Once the login does not require a CAPTCHA. It is easy for hackers to crack the login username and password. So be sure not to close this safety measure for the sake of convenience.

3 Administrator's username and password did not modify, this is the biggest error, super admin has all the privileges in the background, if not add change so loss will be huge. So be sure to change the admin password and complicate it.

4 in the use of FTP login server production files and procedures should be careful not to use some irregular ftp or even unknown with the virus of FTP, which can easily lead to theft by the lawless, so that the black chain through FTP. To be safe, webmasters should change their passwords after using FTP and try to complicate them as much as possible.

5 webmaster in the site to do a program or to achieve a certain effect sometimes because of limited personal ability, on the Internet to find some code to meet their own results, and in these codes and procedures will also have a virus or black chain, can not blindly copy, to check if there is no virus and black chain, This ensures that you are not affected by these malicious links or code when using other people's programs.

Of course, with the gradual improvement of hacker technology, even if it is more careful may be the day of their own website on the black chain, then what should be done at this time.

First, must have the source files, and often back up their own database information, about the DEDECMS system in the background is a backup function, so regular backup, even if the site appears Trojan, can also quickly replace the source program, thereby strengthening the prevention.

Second, and if there is no backup in the case of black chain or trojan, need to patiently find the infected files, and thus deleted.

In short, whether it is based on DEDECMS station or other systems to build stations webmaster, we must observe their own site, do not let more and more trojans and viruses dip to their own website.
