Go to Golang to learn Web security programming practices

People conduct various interactions and information transfers on the Internet, and Web security issues have become one of the most serious and critical issues on the Internet. Especially in large-scale websites, Internet finance and other Internet applications, Web security issues cannot be ignored. Therefore, how to deal with Web security issues and ensure the security of customers and applications has become a common problem for entrepreneurs, programmers, and security experts.

Golang is a very popular programming language in the Internet industry. Its fast, stable and safe features are deeply loved by developers. So, how to practice Web security programming in the Golang programming environment? This article will introduce it in detail.

1. Basic overview

1. HTTP request and response

Golang provides a net/http package, which provides HTTP request event processing and server-side response processing Basic functions and types.

2. HTTP connection

In Golang, HTTP connection supports long connections and short connections. Through long connections, multiple requests can be sent to the same connection to improve resource utilization efficiency. Short connections can reduce the complexity and network overhead of network connections.

2. Web Security Programming Practice

1. TLS/SSL

In the Internet, the TLS/SSL protocol is usually used to ensure the security of data transmission. You can use Golang's TLS/SSL package to implement TLS/SSL encryption of data.

2. Input verification

Input verification is the most basic and important item in dealing with Web security issues. When writing web applications, you must ensure that the input data is legal and safe to prevent injection attacks.

As recommended by the OWASP Security Checklist, input validation of submitted data is required for each application. Input validation can be implemented using the regular expression library and string processing functions provided by Golang.

3. Security configuration

When writing a Web application, you must ensure the correctness of the security configuration. Necessary security configuration includes monitoring binding, request response parameter verification, message format, Cookie/Session security, TLS/SSL connection, etc.

4. Defense against CSRF (cross-site request forgery)

In a CSRF attack, the attacker uses the user's browser and the user's login credentials to send malicious requests to the application, causing the application to Receive the attacker's data and execute the corresponding commands.

You can defend against CSRF attacks by adding Token or one-time verification code in the HTTP request and adding the SameSite attribute to the Cookie.

5. Defense against XSS (cross-site scripting attack)

In XSS attacks, hackers maliciously insert HTML code into Web pages and use page scripts to obtain users' sensitive information or control users. browser.

You can use HTML/JavaScript filters to eliminate XSS attacks.

6. Defense against SQL injection

In a SQL injection attack, the attacker submits data similar to a SQL statement to the application, causing the application's SQL query statement to be modified. The consequences include user data leakage, authentication bypass, and application data instability.

SQL query parameter binding can be used to defend against SQL injection attacks.

3. Summary

This article mainly introduces the practice of Web security programming in the Golang programming environment. Whether you are writing a large Internet application or a small server-side application, Web security is very important.

Security is one of the best ways to protect customers while protecting applications. Therefore, how to ensure the security of web applications under Golang programming is an issue that every developer, programmer, and entrepreneur must always pay attention to during the development process.
