Protects Web servers against hacker attacks

When the operating system is not released and tested in your environment, the Web server should be patched in the first batch to defend against Web server attacks. Anyone can obtain the attack code within a few days of discovering the vulnerability. Within a few days after the hacker obtains the attack, the attack may have already taken place. The attacker can successfully attack the Web server without any patches. There is almost no time to test and install patches for these vulnerabilities, so it is very important to design a configuration plan before the patch is released.

Looking at the Web code, hackers have several ways to manipulate website URLs to execute SQL injection, directory movement, and buffer. There are two common methods to defend against these three types of vulnerabilities. One is to let a person or tool check your Web code, identify and fix vulnerabilities. Alternatively, you can install the application firewall, check the input of the yon ownership transfer, and determine whether it is malicious or incorrectly formatted before it enters the backdoor application. Blue Coat Systems Inc. And Sanctum Inc. Both have such products. It is worth looking at, especially when you think you cannot give programmers the training to write security code again.

If you use a website to sell products or provide financial services, it is of great importance to check the data submitted to the server to process online orders, if your security only depends on the price or account information displayed on the web page, you can use a proxy tool running on a hacker's computer to perform simple operations. Such a tool allows attackers to change the data submitted to your server and remove all the restrictions imposed by the web page itself. A 50-dollar book can be changed to 1 dollar, while a bank account can be changed to another person when funds are transferred or other accounts are displayed in balance.

Based on how you process information submitted by end users, you can use the following methods to verify end users. For example, most programs can be written to check the inappropriate characters and length in the data before processing the submitted data. This verification should be performed on the backend, rather than the input area on the webpage, because the restrictions on the webpage can be bypassed using the proxy tool mentioned above.

Web servers are the first way to access the company's network from outside. By using appropriate Web server protection measures to protect Web servers, you can solve the most risky problems on the network and defend against potential extremely dangerous attacks.
