What are the types of website attacks? A detailed explanation of common categories

in the context of digital operation, websites have become the core carrier for enterprises to acquire customers and display brands, but the security threats they face are also increasing day by day. All kinds of malicious attacks will not only lead to the interruption of website services, but also may cause serious consequences such as user data leakage and damage to corporate reputation. Understanding the types of website attacks is the first step in doing a good job in security protection. This article will disassemble the common types of website attacks from different dimensions, analyze their operation methods and hazards, and provide a clear reference for website security protection.

Types of traffic suppression website attacks?

the core of this type of website attack is to occupy website resources through massive invalid traffic, resulting in legitimate users unable to access normally, which is one of the most common forms of attack.

1, Distributed Denial-of-Service

is a DDoS attack, the attacker controls a large number of infected puppet devices, and sends massive requests to the target website at the same time, exceeding the bandwidth and processing limit of the server, causing the website to be paralyzed. The type of website attack is usually aimed at e-commerce platforms, financial websites and other platforms with extremely high usability requirements. Attacks are launched in promotional activities and important nodes, and the economic losses caused are often incalculable.

2, Distributed Denial-of-service

is a DoS attack, similar to the principle of DDoS attacks, but the attack traffic only comes from a single or a small number of devices. By sending a large number of junk data packets, occupying connection resources, etc., the core resources such as CPU and memory of the server are consumed, so that the website cannot respond to legitimate requests. This type of website attack has a low threshold for implementation and is often used for malicious retaliation against small websites or personal sites.

2, the type of data theft website attacks?

the type of such website attacks to obtain sensitive data as the core target, user privacy information, enterprise business data are the object of attackers coveted, direct harm and far-reaching impact.

1, SQL injection attack

attackers take advantage of unfiltered user input vulnerabilities in website code to insert malicious SQL statements into requests, bypass normal verification logic to directly operate the database, steal user account passwords, transaction records and other sensitive data. This type of website attack exploits code vulnerabilities in website development. As long as there are omissions in the input verification link, it may be exploited by attackers, which is a high-frequency security risk for small and medium-sized enterprise websites.

2, Cross Site Scripting

is XSS attack, the attacker will inject malicious script into the website page, when the user visits the page, the script automatically executes, steal the user's cookie information, session tokens, etc., and then impersonate the user's identity to obtain sensitive data. This type of website attack is more hidden, malicious scripts are usually disguised as normal page content, it is difficult for ordinary users to detect, and it is easy to cause a wide range of user data leakage.

3. Types of permission control website attacks?

the core of this type of website attack is to bypass the permission verification mechanism of the website, obtain a higher level of operation authority, and then modify, destroy or steal the core data of the website.

1, weak password cracking attack

attackers through the dictionary blasting, brute force cracking, etc., try the background of the website, the server login account and password, the use of simple password set by the administrator, the default password and other vulnerabilities to obtain permissions. This type of website attack implementation cost is extremely low, many enterprises ignore password security specifications, resulting in background permissions easily breached, and then the attacker tampered with the content of the website, implanted malicious code.

2, unauthorized access attack

attackers take advantage of the loopholes in the website's permission verification logic to access pages or functions beyond their own permissions by modifying request parameters, forging user identities, etc. For example, ordinary users can view the administrator's background data, and low-authority accounts can execute high-authority operation instructions. The type of website attack requires attackers to have a certain understanding of the website's permission logic, which often appears in customized websites where permissions are not strictly divided.

four, malicious tampering type of website attacks?

this type of website attack to destroy the normal function of the website, tampering with the content of the website as the goal, mainly endangering the enterprise brand perception and user trust.

1, Web page tampering attacks

attackers obtain website permissions, directly modify the page content of the website, implant malicious advertisements, reactionary information, etc., or delete core business pages, resulting in the website unable to display brand information and provide services normally. This type of website attack will seriously damage the brand reputation of enterprises, especially government websites, educational institutions and other websites with strong credibility. The negative impact caused by tampering is difficult to eliminate in a short time.

2, malicious code implantation attack

attackers implant Trojan viruses, mining programs and other malicious code in the website, making the website a carrier for spreading malicious software, while consuming server resources for illegal activities such as mining. The type of such website attack is covert, and may not affect the normal access of the website in the early stage, but it will steal server resources for a long time, and even infect the devices of visiting users through the website, causing chain damage.

sum up, this paper sorts out the types of common website attacks and their harm from the four dimensions of traffic suppression, data theft, permission control, and malicious tampering. The types, objectives and operation methods of different website attacks are different, but they all pose serious threats to the usability and data security of the website. Website operators need to deploy targeted protection measures according to the characteristics of these attack types, and build a security line from multiple dimensions such as code optimization, permission management, and traffic monitoring to ensure the stable operation of the website and user data security.
