This article mainly introduces "what is the security knowledge of daily network station construction". In the daily operation, I believe that many people have doubts about the security knowledge of daily network station construction. The editor consulted all kinds of materials and sorted out simple and useful operation methods. I hope it will be helpful for everyone to answer the doubts about "what is the security knowledge of daily network station construction?" Next, please follow the editor to study!

With the emergence of more and more open source site building systems, coupled with the popularity of cloud services and virtual hosting services, as well as the convenience of domain name registration, a webmaster with no technical background can complete the construction of a website in a short time. However, after the establishment of the website, there will be a lot of problems, which can not be done once and for all, in which the security problems of the website appear frequently, especially when we often see that the website of a certain size at home and abroad has been invaded, the home page has been tampered with, or the website has been attacked for several hours. Therefore, the security of the website is also a big issue that webmasters have to pay attention to. Once there is a big security threat to the website, it may bring great losses to webmasters, such as important data is deleted, users and other related data is stolen, and the website server is DDOS (distributed attack). The server launches bad karma attacks to other hosts on the network in a short time), the failure of the website to operate normally leads to business suspension and economic losses, and so on. As a webmaster, mastering the daily security knowledge of network construction can effectively prevent the related security problems of the website.

First, for those who use open source systems to build stations, security measures must be done. Now there are many open source site building systems on the market, including CMS (content management system), SNS (social network system), online store system, enterprise station building system, etc., although these open source projects are provided free of charge to the majority of users, the open source system is not absolutely secure, especially there are many CMS often have been exposed loopholes, rookie hackers can use very simple methods to complete the intrusion. Therefore, the webmaster friends who use the open source station building system must pay attention to the loopholes of the system, pay attention to the upgrades and patches of the open source system, and fix the loopholes in time. In addition, it is very important to note that the open source site building systems used should be developed by teams with certain strength and brands. Many open source website codes purchased on Taobao are often not tested, maintained and upgraded over a long period of time. It is easy to have security vulnerabilities, and even developers embed malicious and backdoor code in the code to steal website data.

Second, the account information of the website should not be taken lightly. Now many websites, whether the user login of the member center or the account login of the administrator, often do not do a good job in the security of the account. For example, the member registration of many websites has not even verified the number of digits of the account and password, and the basic anti-repetitive registration measures such as CAPTCHA have not been done, and this kind of account can be easily cracked. And casually write a registration program can register a large number of users, the site does not have any security to speak of. Also, the more important website background login entrance, it is recommended that the link should not be exposed in the Internet, do not put management background links on the relevant pages of the site, and at the same time, the search engine crawlers should be placed to grab the background management login links (robots files can be used for setting). There is also a more important thing, which is what many websites do not do now, that is, at the login entrance of the website, the user name and password are transmitted in clear text, and this simple http transmission is easy to intercept, so conditional websites can use https to encrypt the login entrance of the account.

Third, website-related files should be uploaded with caution. After the establishment of the website, we often keep maintenance in the later stage, and some webmaster friends will connect to the file directory of the website server through tools such as ftp or ssh, and upload the modified source files. Here, the uploading of related files on the website is also prone to problems. Some programmers often add some new files when they modify the code, and the most prone to problems is the js file. Because once the js file is embedded in the web page, it will be directly allowed, if these js have not been carefully checked, it may contain some dangerous code, such as when the web page allows js, delete the information on the server or transfer the data to the remote host, which will bring huge losses to the website. Therefore, when uploading files related to the website, we must check the security of the files, such as js, executable file exe, executable script .sh, etc., to prevent malicious files from being uploaded to the server directory of the website.

Fourth, website server security should also be paid attention to. The server security of the website can be said to be the responsibility of the website operation and maintenance personnel, but many websites have no one to do the server security maintenance, but some related server security settings must be done well. It includes that the firewall of the server needs to be turned on normally, the strength of the login account and password of the server must be done, and the failure alarm of the server refers to when the server fails. Webmaster needs to be able to receive alarm reminders in a short time, so that the website can be restored as soon as possible when there is a failure.

Fifth, do a good job of visiting the website. The access log of the website can be viewed in the background of the server and the website. The log of the server can be viewed in the log files related to the WEB server, such as apache, tomcat, etc. It is recommended to set up the relevant access record function in the background of the website, so that when there is a security problem in the website, you can find out the reason more quickly. For example, you can record the IP source, the number of visits, the stay time, the page visited, and so on.

At this point, the study of "what is the security knowledge of daily network construction" is over. I hope to be able to solve everyone's doubts. The collocation of theory and practice can better help you learn, go and try it!
