Explanation:
Separation of duties is considered valuable in deterring fraud since fraud can occur if an opportunity
exists for collaboration between various jobs related capabilities. Separation of duty requires that
for particular sets of transactions, no single individual be allowed to execute all transactions within
the set. The most commonly used examples are the separate transactions needed to initiate a
payment and to authorize a payment. No single individual should be capable of executing both
transactions.
