CC is mainly used to attack pages. Everyone has the experience that when visiting a forum, if the forum is relatively large and there are many visitors, the speed of opening the page will be relatively slow! The more people visit, the more pages on the forum, the larger the database, the higher the frequency of access, and the considerable amount of system resources consumed. “A static page does not require much resources from the server, and it can even be said that it can be read directly from memory and sent to you. However, forums are different. Each time I view a post, the system needs to go to the database to determine whether I have permission to read the post. If so, it reads the content in the post and displays it. Here, at least two database accesses have been made. If the database size is 200 MB,”,…

With the increase in Internet bandwidth and the continuous release of various DDOS hacker tools, the implementation of DDOS denial of service attacks is becoming increasingly easy, and DDOS attacks are on the rise. Due to various factors such as commercial competition, retaliation, and online extortion, many network service providers such as IDC hosting rooms, commercial sites, game servers, and chat networks have been plagued by DDOS attacks for a long time. This has been followed by a series of issues such as customer complaints, involvement with virtual host users, legal disputes, and business losses. Therefore, resolving the issue of DDOS attacks has become a top priority for network service providers. 1、 What is DDOS? DDOS is an abbreviation for Distributed Denial of Service in English, meaning “distributed denial of service”. So what is a denial of service? It can be understood that any behavior that can cause legitimate users…

1、System blue screen, frequent crashes, restarts, slow response speed The hardware structure and operating system of the server are very similar to those of our ordinary computers. Therefore, just like our computers, they may be infected with viruses, crash, blue screen, restart, and other failures due to system vulnerabilities, software conflicts, and hardware failures. They may also be unresponsive due to excessive garbage cache information. 2、Remote Desktop connections exceed the maximum number of connections Since the server defaults to allowing 2 connections, if you forget to log off after logging in and close the remote desktop directly, the server recognizes that this login is still left on the server side. The most common occurrence of this situation is to restart the server. However, if it is during peak hours, the losses caused by restarting the server are obvious. At this point, you can use the mstsc/console command to forcibly log…

1、 Regular backup of website data: Regular backup of website data can be used to recover the attacked website, even if the website is attacked or accidentally deleted some website information, it can be recovered at any time. For this website operation and maintenance, website backup is the absolute principle. 2、 Website program system update: Website programs and server systems are regularly updated with the versions and patches used, which can eliminate some existing security vulnerabilities and prevent potential opportunities for hackers. 3、 Regularly check and kill website viruses: Regularly check and kill website viruses can prevent hackers from further breaking or stealing website data, and can also timely delete the leaked files of the website backdoor. 4、 Website file permission setting: Set reasonable permissions for website server files, such as canceling write or execute permissions for some important files executing programs, to prevent hackers from tampering with website data….
