How to deal with web attacks?

Web attacks refer to a type of attack that exploits vulnerabilities in Web applications to carry out malicious behaviors. This form of attack is becoming increasingly common, causing huge losses to enterprises, governments and individuals. How to deal with Web attacks has become an urgent problem in the field of network security.

1. Common types of Web attacks

1. SQL injection attack: The attacker injects malicious code into the input box to use the system to perform malicious operations on the query results of the database.

2. Cross-site scripting attack (XSS): Attackers obtain user information by injecting JavaScript code, thereby further tampering with web page content and stealing user data.

3. Cross-site request forgery (CSRF) attack: The attacker takes advantage of the flaws of the attacked server to make forged requests to users, thereby obtaining or tampering with user data.

4. Injection attack: By injecting malicious code into the input box, the attacker can obtain system administrator rights, thereby tampering with system files and restarting the server.

2. How to prevent Web attacks

1. Develop secure Web applications: Web application security issues should be considered from the beginning of design, including secure coding, data verification and integrity Sexuality verification, etc.

2. Continuous vulnerability assessment: There must be a continuous process for detecting and repairing vulnerabilities in web applications, and even tools must be introduced for automated detection.

3. Data filtering and verification: The input and output data of web applications need to be strictly filtered and verified to defend against malicious requests, pages and scripts to prevent data from being stolen or tampered with.

4. System access control: Authorization and permission control are required for access to sensitive information in web applications to reduce the attack surface.

3. How to respond to Web attacks

1. Isolate the server under attack and prohibit system access in a timely manner to avoid the spread of attacks.

2. Save the attack log, analyze and trace back, find the source of the attack, track the attack, and quickly solve the problem.

3. Promote vulnerability information sharing and strengthen collaboration. Establish a multi-party cooperation mechanism among industry, society, and government to form a professional website security prevention and response system to improve the efficiency and level of defense and response.

4. Summary

Faced with increasingly complex forms of Web attacks, a Web application that is comprehensively guaranteed in terms of code security, vulnerability assessment, data maintenance, access authorization, etc. is the most effective Web attack prevention methods. At the same time, responding to Web attacks requires the joint participation of all parties and the establishment of a multi-party industry security alliance to jointly prevent network security risks.
