Always listen to many webmaster, VPS is like a small villa, on the site of a variety of data will have a small upgrade. Oneself also therefore am, from the fictitious space to move own data to the VPS, this thought the operation establishment security and so on like the fictitious space as simple, after some things only then understood that the VPS does not do the security protection, to the website influence how big.

Events caused by missing VPS security settings:

1 just transferred data less than a week or so, found Taobao guest data is not normal, the daily normal income, suddenly began to reduce. Thought is not enough publicity, continue to do outside the chain and Taobao guest work, have a few days, even less income. Inadvertently open a Taobao link, found that the PID let changes. Hurriedly landing VPS, check the space situation, query online data, the original is the key file permissions are not set, let others through remote to modify the.

2 One months or so, a friend reflects my site to open a bit slow, hurriedly and VPS customer service Contact, told me the entire server site is slow, is checking the reason. It is because of this reply, paralyzed oneself, no matter. After a few days to find Baidu included in the reduction, and the keyword ranking in the regression. Feel that the site must be a problem, landing space to view. Unexpectedly found space inexplicably created 2 new users, and their running process is hanging machine brush flow software running.

3 during the Chinese New Year, less maintenance of the site, in the query site data, online monitoring reminder home has a horse phenomenon. Hurriedly on the space query, found that multiple files to modify and add some code.

Handling after event:

1 Set the key file permissions to the minimum, regular query file modification time and PID.

2 when there are 2, 3 problems, at that time to remove the user's method to clean up, but in a few days there will be hacker intrusion software. Always have a headache how to deal with. Until one day the VPS remote can not log in, reinstall the system after the epiphany, what causes the front time. The main reason is that when the blog database is created, it defaults to the null password of root, resulting in system intrusion. After the system has been restored, the security settings of the database have been strengthened, and the server has finally returned to normal.

Web site security problems in the virtual space, the total is not, so many beginners do not attach importance to, when replaced by a VPS, a lot of security aspects of the settings, need to do their own. At this time I think must first more in the Internet Query security settings, the need to migrate their data permissions set clear. Database passwords and permissions to focus on.
