It is perfectly feasible to have the same control or barrier deployed to manage several risks. It may be that, in some situations, one control is declared effective in managing one risk but only partially effective in managing another and that is when there is a need for care to be taken.
Where the control is only partially effective, there may be a temptation to adjust or modify it to strengthen it in relation to a particular risk – but in doing so you are unaware of its deployment elsewhere.
To avoid introducing change that fixes one thing but weakens another, an effective SMS Information Management solution provides the ability through control-centric views to determine where else a control is deployed. This provides insight and awareness of what else needs to be considered ahead of any proposed change.
