How do hackers attack web servers ? Network attacks occur from time to time, especially the various means of attacking websites make it hard to guard against. While we cannot eliminate cyberattacks , we can protect against them effectively through defenses. For example, select an anti-attack server. Choosing a high-defense server can effectively defend against large-traffic attacks such as DDoS, thereby preventing and reducing the losses caused by the attack. The following are some commonly used attack methods by hackers. Knowing these attack methods allows us to make more targeted defenses.

Forged information attack means that network hackers construct a forged path between the source computer and the target computer by sending forged router information, so that the data files flowing into the target computer all pass through the computer controlled by the network hacker, and then obtain the information in the data file. Personal sensitive information such as bank account login passwords.
The resend attack means that network hackers collect special IP data files to forge their data information, and then resend the IP data files one by one, and then deceive the target computer that reads the data, complete the attack, and destroy the security of the server.
Attack on Protocol Weaknesses
In a local area network, the source route selection of an IP address allows the IP data file itself to choose a route to the target computer. When a network hacker tries to connect to an unreachable computer X located behind the server firewall, he only has to set the IP address source path option in the sent request message, so that a specific destination address of the message is biased towards the server. Firewall, but the final detailed address is biased towards computer X.
When the packet reaches the server firewall, it is allowed to pass because it is biased towards the server firewall rather than computer X. The source route of the packet processed by the IP layer of the server firewall is changed and sent to the internal network. In this way, the packet arrives at the unreachable computer X, thus completing the attack on information protocol weaknesses.
A data-driven attack is an attack that is required to enforce a unique program that appears to be harmless on the surface and is sent or copied by a cyber hacker to a target computer. The attack can allow cyber hackers to alter network security-related documents on the target computer, thereby making it easier for cyber hackers to break into the target computer next time. Data-driven attacks mainly include buffer overflow attacks, format string array attacks, input validation attacks, synchronization system vulnerability attacks, and trust system vulnerability attacks.
The above content is an introduction to how hackers attack the website server. For DDoS, CC and other large-traffic attacks, the firewall can quickly and intelligently identify, effectively defend against various attacks, improve the server defense mechanism, and ensure the safe and stable operation of the server.
