Expert Solution & Answer
Chapter 14, Problem 14.8E
Explanation of Solution
Recognition resistance and strategies:
If the user is trying to move the prices from one trading system to another by making unauthorized access, the recognition, resistance and recovery strategies come into force so as to prevent it.
- With the use of recognition strategy, the operators of the system identify the unauthorized prices movement, which leads to system failure. The system then sends text messages to all the users that an unauthorized person is making the changes in prices.
- With the use of resistance strategy, the critical parts of the system are focused as it identifies the possibility of any cyber-attack on any trading system. As financial trading plays a vital role, it is focused in it.
- With the use of this strategy, the critical services of the system can be restored when the failure of system is occurred. With this the important trading information can be restored easily...
