How do cloud virtual hosts defend against attacks? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

Virtual hosts mainly rely on firewalls to defend against network attacks, in which ddos attack is a common way of network attack.

DDoS attack is a common attack on servers, and there are many ways to attack. The most common attack is to occupy service resources through service requests, resulting in users being unable to get service responses. The most effective way to prevent DDoS attacks is to choose a computer room with hard defense. Hardware firewall can effectively prevent DDoS attacks and hacker attacks. Although hard defense can effectively prevent DDoS attacks, it is basically ineffective against CC attacks. CC attacks need to be defended by software firewalls. Webmaster can consider adding Baidu Cloud acceleration, 360 website Guardian, Cloud Shield and other network defense products, some of which can be used free of charge.

The following measures can effectively improve the defense capability of virtual hosts:

1. Select a security system

First of all, when building a website, it is recommended to choose a well-known site-building system, the security of such a system has been verified by the majority of webmasters, and common loopholes are basically eliminated. Do not choose some personal systems or paid systems. When personal systems are attacked by hackers, due to many loopholes, it is very easy to disclose relevant information, and all the source codes of the paid system are in the other party, and the security is not high. Unless you sign some confidentiality agreement or develop your own. Choose a well-known site building system, can be customized, you can also use the free version, even if the free version is also a collection of people's thinking, the website security is relatively high.

2. Take precautions against the website.

Do a good job of your own website security measures, such as changing the default database, default password and background, etc., in the background login, you can add some CAPTCHA, so as to effectively avoid violent cracking.

3. Set the security password

When using the virtual host, set more passwords, such as security passwords, including relevant member passwords, FTP passwords, mailbox passwords, database passwords, etc., do not repeat as much as possible, and the density length should be more than 8 digits. The password setting is more complex and must contain capitalization, numbers and special symbols. Common passwords are also not recommended, and then the passwords are changed regularly.

4. Change the database information

The database information can change the suffix and make the storage directory more complex to avoid being easily guessed where it is and easy to download.

Access database suffix do not use .mdb, it is recommended to use .asp / .asa, to avoid being downloaded by hackers. The database name is recommended to start with #, and the directory name is more complex to prevent hackers from guessing.

5. Do not upload files at will

Usually do not upload files at will, some Trojans or viruses are uploaded to the virtual host through these files, and then execute these suspicious programs to steal relevant information.

6. Clean up the files on the virtual host frequently

Often clean up the temporary files on the site, do not easily choose to save passwords, many password leaks are caused by remembering passwords when browsers visit.

7. The website does not contain private information

The website should not contain some private information. after all, the virtual host still has a certain degree of instability, and the network is not absolutely secure, especially the important content is placed on the virtual host, which is easy to cause irreversible losses.

This is the answer to the question about how the cloud virtual host defends against attacks. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
