Appendix 2
Securing WebAssembly Modules

I devoted the vast majority of the book to illustrating how WebAssembly modules can be created, hosted, consumed, and integrated. What I didn’t talk about was, once you’ve got a WebAssembly module, what are the security concerns and how do you mitigate them?

This appendix will briefly mention a few things that you should keep in mind when considering the security implications of using WebAssembly. It is by no means an exhaustive reference or guide.
