Specific measures to strengthen maintenance and safety construction after the production of portal websites is launched
To enhance the necessity of maintaining and safe portal websites, we must not only ensure the maintenance and safe portal websites from a system perspective, but also take a detailed technical approach and truly enhance the maintenance and safe portal websites from a technical level. You can mainly take action from the following aspects:
The portal website should choose a structural design with high security
Judging from the current operation and maintenance forms of the website, three main forms are mainly adopted: collection, reporting and sub-station, among which the sub-site form can best represent the trends and trends of the website development. Therefore, we need to choose a design plan with higher security in terms of structure. The following plans are the main ways to portal websites:
Portal websites should actively adopt web page anti-tampering technology
Judging from the malicious attacks suffered by the portal website, 80% of the attacks are manifested as web page tampering. Hackers mislead network users by tampering with the portal website web pages, thus having a great impact on the normal operation of the portal website. In order to reduce the malicious attacks on the portal website, we should actively adopt the following web page anti-tampering technology to maintain the security of the portal website. Plug-in scanning technology uses the method of scanning web page files one by one from the outside to determine illegal corrections to web pages. This technology usually has a certain time distance, and the more files the website has, the longer the time distance, and it cannot guarantee that the web pages corrected by hackers will not be seen by visitors. It can be seen that although plug-in scanning technology has certain effects on avoiding attacks on web files, this technology also has certain technical limitations, that is, the longer the full scan is, the longer the scanned files are, which also leads to the inability to respond immediately, which leads to relatively slow responses when viewed with certain offensive files. Therefore, when we apply this method, we should try to shorten the scanning time. The anti-tampering system adopts the central embedded technology, and its tampering detection module operates on Web The server software is internal to Web Servers are seamlessly separated. every time Web When the server sends web pages to the outside, the system stops the web page anti-tamper detection, so that the authenticity of each web page can be ensured in real time. Judging from the current operation of the portal website, the central embedded technology has undoubtedly become an important skill in dealing with malicious cyber attacks. While applying the embedded technology in the center, we must stop using plug-in scanning technology and embedded technology in a comprehensive manner, give full play to the advantages of the two in different links of the website, effectively deal with the onset of web page tampering, and improve the security of the website from the big to the purpose of improving the security of the website. The triggering technology is to embed the system's tamper detection module into the operating system kernel, resulting in all files being illegally changed and things being retrieved by the trigger without delay. This mechanism is completely different from scanning technology and center embedded technology. It does not require the tedious process of comparing and analysis with backup. It can complete the real-time monitoring and low system resource utilization. It is currently an advanced anti-tamper detection technology. The event triggering technology effectively deals with the problem of reaction after a website is maliciously attacked, improves the speed of information reactions, and improves the quality of the entire information reaction. Therefore, in the operation of the portal website, we must actively use event triggering technology to deal with website web page tampering attacks.
The portal should regularly stop inspecting and evaluating Ping An Technology
From the above analysis, we can see that plug-in scanning technology, center embedded technology and event-triggering technology are the main tricks to deal with website web page tampering, and plays a positive role in maintaining and establishing portal websites. Therefore, we must actively promote the application of these three technologies. However, with the rapid development of network technology, if we want to ensure that these three technologies can continue to work, we must regularly stop the effects of these three safe technologies to ensure that they can play a normal role. Although plug-in scanning technology has achieved positive results and played an important role in the safe establishment of the portal website, it is limited by the technology itself. Even if plug-in scanning technology is used, the public cannot prevent access to the tampered web page. It can only discover and stop recovery after being tampered for a period of time, so the public is very likely to access the tampered web page. Based on this situation, we must regularly stop inspecting and evaluating the external surface scanning technology to verify whether the technology can still be effective. The inspection process is mainly completed by imitating malicious attacks. By using known cyber attacks to imitate malicious attacks, the practical effect of this technology is verified. Regarding plug-in scanning technology, the advantages of center embedded technology are becoming more prominent and more effective, and plays a prominent role in the security establishment of portal websites. It not only improves the security level of the entire website, but also improves the technical strength of the website. Judging from the existing application effects, the advantages of center embedded technology are mainly to maintain it. Web The last threshold for web pages to leak, so the tampered web pages can be completely eliminated and accessed by the public, and truly foolproof. Therefore, when we stop testing and evaluation of the center's embedded technology, we must control it before it can stop testing and evaluation, and verify whether its control can still be effective. Since the security check is only stopped when the normal web page is published, the impact on web page access is simply zero, and the additional server load occupied is basically zero. Things trigger technology: It doesn't ensure that corrections to files are captured in every way (For example, writing directly to the disk, writing directly to the kernel driver, applying operating system flaws, etc. )，Very easy to be bypassed by professional hackers; and once victorious, it has no wrist to detect and recover. Its technical characteristics determine that it is similar to antivirus tools (Use black to prevent black )Instead of a system specifically targeting website maintenance.
