Ban JavaScript programs

Mr. Yang, who has been established recently, is a senior computer programmer. He has experienced the evolution of computer languages ​​and leaps in IT technology, witnessed numerous network storms and network security threats, and has become more and more aware of code security. of attention.

When he writes programs, he often considers some risk factors, such as inputting unreliable data, buffer overflow, code injection and other issues. Mr. Yang believes that many coding risk factors can be avoided through some coding skills and tools.

However, in a recent discussion, Mr. Yang and his colleagues discussed a seemingly exaggerated idea: banning JavaScript programs from running anywhere.

This seemingly unrealistic idea triggered heated discussions among everyone. Some colleagues objected, arguing that JavaScript is one of the most popular web programming languages ​​today and cannot be banned. Mr. Yang believes that JavaScript is a huge security hole because it can run on the client side and can manipulate the browser DOM, which means it can execute malicious code on the client side and can be obtained from the user's computer. Confidential Information.

Mr. Yang pointed out that Javascript codes can be maliciously modified on the client side, especially when they come from untrusted sources. For example, hackers can use cross-site scripting (XSS) attacks to inject malicious code into the victim's Web page and control the victim's computer by running JavaScript.

These statements have attracted public attention and discussion. Everyone believes that JavaScript does have many security risks, but banning it seems unrealistic and feasible.

However, Mr. Yang does not really want to ban JavaScript, but proposes a strategic idea: we should prioritize the security of the code instead of blindly using popular languages ​​​​and frameworks. Therefore, we should understand and master the risks of using JavaScript and take more preventive measures to reduce risks.

Some colleagues pointed out that restrictions and stronger supervision on the use of JavaScript are necessary. For example, use common web application firewalls (WAF) to inspect and filter input data from JavaScript, and use appropriate coding skills and practices to reduce the risk of your code.

In addition, there are some tools that can help programmers improve the security of JavaScript code. For example, you can use a code scanner to check for potential code vulnerabilities and security issues instead of going through all the code manually.

Mr. Yang’s ideas have been recognized by everyone. Everyone believes that code security is very important, and using popular languages ​​and frameworks is not inevitable. Programmers should improve their security awareness and take more precautions when writing code.

In general, JS needs to continue to improve and strengthen security measures. As programmers, we also need to strengthen our own security awareness and take appropriate measures to ensure the security of our code. While banning JavaScript is unrealistic, we can improve the security of our code by strengthening precautions and using the right tools.
