Many times, several lower cost controls can be combined to yield better risk reduction than one complex expensive control.
Process designs that embody proper controls can yield operational, security and regulatory compliance benefits. To be effective and efficient, they must be implemented on the basis of risk such that the controls used reduce the risks to objectives to an acceptable level.
Risk mitigation beyond that point can result in needlessly expensive processes that are too complex for people to sustain in the long-term. Processes need to be designed with these requirements taken into consideration to yield not only controlled processes but, even more importantly, controlled processes that can actually be sustained over the long-term.
