Cyber attacks have become one of the most deadly security problems in today's Internet security environment. As we all know, with the continuous development of digital technology, network communication has become the basis of most people's daily life and business activities. However, with this comes an increase in cybersecurity risks and cyberattacks. If you want to learn more about network attack methods, this article will give you a detailed analysis.
DOS attack (Denial-of-Service) refers to the attacker occupying the server's resources through a large number of false requests, causing the server to be unable to Other requests will be processed within normal hours. A DDOS attack (Distributed Denial of Service) refers to an attacker sending false requests to the target server through a large number of computer terminals at the same time to cause the target server to crash. DOS/DDOS attacks are often carried out by hackers using a large number of zombie computers to attack a specific target.
SQL injection is a technique that exploits security vulnerabilities in web applications to attack databases. By injecting malicious code into the data submitted through website forms and performing SQL queries, you can bypass restrictions or access sensitive data in the database.
XSS attack (Cross-site scripting) is to inject malicious scripts through places where data can be entered on the website, such as forums, search boxes, etc. Code, in this way attackers can implement cross-site scripting attacks on the website, and then illegally obtain various user information, such as account numbers, passwords, etc.
Hacker attack, also known as "backdoor attack", refers to the attack that attackers usually use through unpatched vulnerabilities or malicious programs. In this way, malicious code is implanted into an application. After the program is attacked, it can provide the attacker with free access to the victim's computer and network.
Trojan horses use program vulnerabilities or bypass security software protection to create malware and run it on a computer or server to achieve the attacker's purpose. Including and remotely collecting some sensitive information, personal privacy, etc.
Attackers can also use traditional fraud methods, such as pretending to be customer service personnel from financial institutions or online stores, through email or social networks, etc. Methods to obtain user information or defraud funds.
In short, the forms of network attacks are rich and diverse, and the attack methods are also diverse. Therefore, in response to these attack methods, we need to strengthen our security awareness, protect our confidential information, and do not click on emails and links at will. At the same time, administrators should take necessary preventive measures, such as encrypting data, updating firewalls, etc., to strengthen network security defense.
