How does the construction of Shenzhen website improve the security performance of the website?

For website operation, in addition to improving website ranking and increasing website traffic, website security should also be improved. If the security work is not in place, even if the ranking is high, once attacked, not only the ranking will be lost, but also the website content is difficult to recover, so it is particularly important to do a good job in preventing hacker attacks. below Website construction The company will briefly introduce common methods to prevent website attacks. 　　

　　 First, guard against attacks by hanging horses and black chains. This kind of attack is not very harmful to the website, but it cannot be ignored. Once your website is hung up or targeted by black links, you will often encounter abnormal phenomena when opening your website, such as the content of the webpage is tampered with, or even many webpage windows will turn on the lights as soon as they are opened. This is because my website has been attacked by hanging horses or black chains. Moreover, the punishment of search engines on such websites is also very heavy, and we cannot take it lightly. 　　

The response is to backup the website. In addition, it is necessary to install necessary fire protection requests, set corresponding security policies, and regularly check the export links of the website to see if there are suspicious links. In addition, you can also query through some webmaster tools released by Baidu, which can effectively avoid the risk of hanging horses or being targeted by the black chain.

　　 Second, the prevention of network traffic attacks. This attack is called CC attack, also called bandwidth attack and application attack. The direct result of this attack is website paralysis, because the traffic of a website visiting at the same time cannot exceed the critical value, which is closely related to the quality of website space. For grassroots webmasters, a little traffic attack often leads to website paralysis. And if the website is often paralyzed, Baidu will also be punished, so webmasters still need to pay attention. 　　

The way to deal with this attack is to buy high-quality website space, or buy some space security value-added products to deal with traffic attacks. Usually, such attacks can only kill viruses. If necessary, the space needs to be changed, which requires the webmaster to backup the website data at ordinary times to avoid the risk of data loss when changing the space. 　　

　　 Third, attacks that destroy data. This attack will have a great impact on webmasters, especially for webmasters who do not like to back up their own data or who do not back up their data frequently. Such attacks are now illegal. The common attack method is SQL injection, obtaining the user name and password of the database, and then changing and stealing data at will, or even replacing the website page, which poses a great threat to the operation of the website. 　　

For such attacks, in addition to backing up data, you need to set corresponding permissions, update relevant database systems in time, and patch these systems. Even if you have to change your user name and password from time to time, it can effectively avoid the disclosure of user name and password. At the same time, the user name and background password applied to the website remote desktop, FTP and other related software need to be modified from time to time. The principle of password setting should be the combination of numbers and letters, so the probability of guessing the password is extremely low. 　　

In short, website security will play a very important role in the sustainable operation of websites. In many cases, webmasters choose to leave the website circle because the website is attacked and demoted, leading to no intention of turning the tide again. Therefore, in order to prevent such a tragedy from happening again, it is very necessary to do a good job of prevention in advance.
