Sandboxing is a technique that ensures code runs in a secure environment. This method prevents potential security vulnerabilities and maintains system integrity. GraalVM effectively implements this technique for script extensions. ## The Role of GraalVM GraalVM is a virtual machine that supports multiple languages. Its sandboxing features enable secure execution of code written in different languages. This is particularly advantageous for dynamic scripts. ## Security Advantages GraalVM's sandboxing features prevent malicious code from accessing system resources. This enhances application security and protects user data. Additionally, isolation ensures system stability. ## Performance Impact Sandboxing techniques can often cause performance loss. However, GraalVM minimizes this loss with its optimized structure. This achieves a good balance between security and performance. ## Use Cases GraalVM's sandboxing features are particularly useful for plugin systems and applications requiring dynamic script execution. This provides developers with a more secure and flexible environment. ## Future Potential GraalVM's sandboxing features will play a significant role in developing security-focused applications. This technology will be increasingly adopted in modern software development processes. ## Sources covering this story - https://www.reddit.com/r/programming/comments/1v3fxxn/sandboxing_script_extensions_with_graalvm/ — --- _Summary written by Brifing from the original reporting.
