Cottony scale insects or mealy bugs are the culprits. Unfortunately anything that will control them will also damage your cactus. You can try scrubbing them off with a brush but generally they will return. I hate to say this but sometimes the best control is to cut away the infested plant parts or dig and remove the cactus and replace it with a healthy specimen.
