Yes; to expand on that a bit -- you can do fault injection in a chaos experiment. You can also do many other things within an experiment that would be difficult to classify as fault injection; for example, a sharp increase in the number of customers making requests to your service isn't really a fault. Chaos Engineering then wraps all of those techniques in a framework of experimentation and analysis. That's the discipline, which encourages you to proactively make improvements to Availability, and now Security as well.
