I summarize it from what I read, can someone verify whether I am corrected?
Separation of duties -> ensure no single person take all control of critical task prevent/detect fraud may have collusion
Separation of privilege -> similar to SoD but needs to fulfill least privilege
Segregation of duties -> combined with least privilege and avoid conflict of interests
Two person control -> I do the task and you review the task
Split knowledge -> no one has full knowledge/privilege of a task I own the first part of password and you own the second part, then need combine both to access system
Dual control -> two people need to do something at same time I press the button at position A and you press the button in position B to shoot the bomb
