How can I detect website vulnerabilities and backdoors and prevent attacks?

How do I know if your website has any vulnerabilities? Recently, many websites have suffered various forms of attacks. The motives for hacker attacks and intrusions are different. The target of hacker attacks is also uncertain. As a corporate network administrator or CEO, are you worried that your website will suffer the same fate?

Common hackers intrude almost of websites by uploading vulnerabilities, violent libraries, injections, and side-by-side injection. Of course, there are more advanced intrusions. Some hackers follow up on a website for several months to find an intrusion point. Let's take a look at these websites that are easily hacked.

1. Upload Vulnerability

This vulnerability was the most widely used by hackers in the DVBBS6.0 era. Using the Upload Vulnerability, you can directly obtain WEBSHELL, which has a high level of threat. The current upload vulnerability is also a common vulnerability.

Happy cloud reminder:

Most website programs are modified on the basis of public programs, and there will always be vulnerabilities in the programs. Smart website administrators should learn to master the above tools and pay attention to the latest vulnerabilities in their web programs. Use the above tools for self-detection to ensure website security.

2. brute-force database:

Many websites can exploit this vulnerability. Very dangerous!

Happy cloud reminder:

Databases are always what hackers are most interested in. Database Security is not fully considered by every programmer during programming. After going online, you should find a professional security company to test database penetration testing to ensure database security.

3. injection vulnerability:

This vulnerability is currently the most widely used and highly lethal. It can be said that Microsoft's official website also has an injection vulnerability.

Happy cloud reminder:

The websites of large companies should be conducted by senior programmers who understand security programming. After development and launch, professional companies should be invited to perform security testing. To ensure program security and reliability!

4. Side note:

When we intrude into a station, this station may be robust and impeccable. We can find a site with the same server as this station, and then use this Site for Elevation of Privilege, sniffing and other methods to intrude into the site we want to intrude.

Happy cloud reminder:

For websites of large companies, it is best to have their own independent servers. In addition, you can disable ports, restrict logon IP addresses, and patch servers in a timely manner to ensure server security.

Of course, there is still a relatively simple method when the company does not have a full-time technical level or a relatively general technical level. The Technical Director of Xiamen lesu cloud Information Technology Co., Ltd. proposed a concept: Package Intelligent High-defense CDN and website security services into products, so that every website can be impeccable! As long as you dare to use it, no one will dare to do it!

Leave professional things to professional people: Put the website on a technical company dedicated to network security, and use existing platforms and technical strength to automatically detect website security, vulnerabilities, and backdoors, trojan and other problems, you can automatically detect in the system every day, and promptly remind users to improve which programs and server security vulnerabilities.

Providing professional services to the public, improving websites with perfect technology, and facilitating users with a user-friendly platform to defend against malicious attacks, prevent hacker intrusion, and reassure the CEO of network management, to reassure enterprises.
