Golang development experience summary: several methods to improve code security

Golang is an efficient, lightweight, easy-to-develop programming language with good concurrent processing capabilities and memory management mechanism. However, with the gradual increase in Go language applications, security issues have gradually become an important topic. Therefore, this article will share several methods to improve the security of Golang code.

1. Avoid using global variables

Golang’s concurrent processing mechanism will cause the value of global variables to be modified by multiple coroutines at the same time, causing race conditions and data competition issues . In order to avoid these problems, it is recommended to avoid using global variables as much as possible and instead localize variables by passing parameters. When global variables must be used, locking, synchronization and other measures can be taken to ensure the security of concurrent access.

2. Use newer Go language versions

Newer versions of Golang usually contain more security patches and improvements, so it is recommended to use the latest Golang version for development app. In addition, in order to ensure the security of the code, the code base also needs to be updated and maintained regularly.

3. Input legality verification

Input legality verification is an important step to ensure application security. It can be done through regular expressions, limiting input size, format control, Implemented through type checking, etc. When verifying input legitimacy, you need to pay attention to some common security vulnerabilities, such as SQL injection, cross-site scripting attacks, etc.

4. Use as many libraries and frameworks as possible

In Golang, there are many mature libraries and frameworks that can be applied in development. These libraries and frameworks are usually passed Strict testing and security auditing can effectively improve the security of applications. When choosing libraries and frameworks, pay attention to how well documented and community supported they are, as well as whether they have any historical security vulnerabilities.

5. Deletion of debugging information

During the development and testing stages, debugging information in the console is very useful, but this information usually contains some sensitive information, such as passwords , keys, etc. In order to prevent this information from being leaked, all debugging information needs to be deleted or hidden before the application is released.

Summary:

The above methods can help Golang developers improve code security, but this is only a starting point. In actual development, it is also necessary to pay close attention to security issues and promptly discover and resolve security vulnerabilities in order to improve the security and reliability of applications.
