Many corporate websites have professional web site security administrators, mainly responsible for the day-to-day maintenance of site security. Usually a Web site security administrator will also be responsible for network equipment (including routers, servers, switches, firewalls, etc.) installation, management, day-to-day maintenance. However, in many cases, Web site security administrators can not prevent the emergence of Web site security issues. So what are the reasons for the security problems of a website?

A lot of web design only considers the normal user stable use, but ignores the flaw existence

Most Web developers and designers know very little about the site's attack and defense techniques, and they usually only consider how to make the site work for users. These designers pay little attention to secure code design and rarely consider vulnerabilities in the development of Web applications. But the site's own vulnerabilities will be constantly dug out by hackers, hackers will directly use these vulnerabilities directly or indirectly to obtain benefits, resulting in huge loss of the site.

In this regard, the design of the Web site must consider the existence of loopholes. Hackers usually use the Web server vulnerabilities or Web pages of their own security vulnerabilities to attack, so the site security administrator to do a good job in the Web site security vulnerabilities detection, once the vulnerability problem, we must promptly deal with these vulnerabilities.

Website lacks effective defensive measures

Many of the site's defensive measures are too backward, some based on feature recognition of intrusion prevention technology and content filtering technology, and can not be very good against hacker attacks, also can not achieve the purpose of protecting the site. A good example is SQL injection, Cross-site scripting this feature is not unique site attacks, if the site is based on feature matching technology defense attacks, site attacks can not be accurately blocked. This is also why so many hackers have chosen SQL injection as one of the preferred attack techniques for intrusion sites.

Another reason for the site's poor defense is that webmasters don't know the value of the site. Some webmasters on the importance of site security is not given enough attention, they think a site's value is either a server, or the construction costs of the site. Based on this mistaken understanding, they think that it is not worth adding more to the Web site security precautions for this server than it costs.

In fact, when a website is attacked, the loss is not measured by the cost of a server or Web site. The information assets of the enterprise website after being attacked by hackers (such as user data steal), will let the enterprise undertake the loss of intangible value. Therefore, responsible for the site security units and personnel must correct the value of the site awareness, strengthen the site security measures the importance of awareness. Only in the awareness of the importance of site security, will invest enough material and human resources to improve the site's defensive measures, and truly achieve a good site defense level.

Failure to detect hacker intrusion in time

Some hackers gain access to Web site control through vulnerabilities in Web servers or Web pages themselves, and hackers often choose to tamper with the site's content in order to spread some illegal information or simply want to show off their computer skills. This kind of hacking behavior is not the most terrible. Once the pages have been tampered with, hackers will be caught in a leak, and they cannot conceal themselves after gaining control of the site. Web site intrusion, Web site tampering will bring a lot of bad impact on the website, but the hackers themselves do not have a direct interest. This kind of hacker intrusion behavior can also be found and processed in time, and then the hacker intrusion on the site to minimize the negative impact.

However, many web site security problems arise because the site managers did not timely detection of hacker intrusion behavior. Some hackers in order to control the site to generate direct economic benefits, the use of loopholes to gain control of the site, not in a hurry to leak their own, the Web page hanging horse is this behavior. Hackers in the access to the site, you can use the site, users will browse the site of the Trojan Horse. In this very covert way, hackers can directly gain benefits. This is why the website hangs the horse to cause the very big harm to the website.

Hackers usually do not know the user to visit the site of the Trojan Horse, the result is the users of the Trojan horse's confidential information stolen. In this case, the site itself is not affected by the normal service function, but the user browsing the Web site has been the harm of Trojan, and hackers also use the site to take a walk Trojan program. Because of this kind of hacker behavior concealment, many websites have not found the website to be hanged the horse in time.

This kind of concealed horse behavior is generally through the Web page to load a user can access the site to automatically create additional download links to complete the Trojan download, the entire Trojan download process can be very covert to complete, so the general site of its own local virus software is also unable to find, identify this hanging horse entity. This hacker invasion, not be found in time, may bring huge potential losses to the site.

Site security problems found, but can not be completely resolved

The rapid development of website Technology also makes the website security problem become more and more prominent. But many web site development and design companies do not know much about Web site security Code design. This also determines that in the process of Web site development and design, despite the discovery of security issues, still can not completely solve these security problems. found that the site has security problems and security vulnerabilities, almost no site specific vulnerabilities to the principle of the source code to transform. On the contrary, the solution to these security problems is only to stay on the page repair. This can also explain why many Web sites in the Web site tamper-proof or Web site recovery software under the premise, but also suffer from hacker attacks.

Site maintenance personnel on the site defense technology is also caused by the site security problem can not be completely resolved an important reason. Although many websites have professional website maintenance personnel, they do not have comprehensive website security knowledge to solve the problem after discovering the website security problem. For this kind of enterprise website, can hire the relevant professional website safety Maintenance company to carry on the omni-directional security diagnosis to the Enterprise website, once discovers the website security question, takes the safety measure to solve these problems thoroughly.
