Question
Statement: Due to the increasing number of cyber
fraud cases, the central bank has advised all commercial banks to implement additional layers of authentication for online transactions. Assumptions: I. Additional layers of authentication will reduce cyber fraud cases. II. Commercial banks are currently not using sufficient security measures for online transactions.Solution
Assumption I is implicit because the very suggestion of implementing more authentication layers is based on the belief that it will help reduce cyber fraud. Assumption II is also implicit. If the current measures were already sufficient, there would be no need for a recommendation to increase security. So, both assumptions are directly linked to the logic behind the central bank’s advisory.
