The implementation of continuous monitoring controls is the BEST option where:
A.
incidents may have a high impact and frequency
B.
legislation requires strong information security controls
C.
incidents may have a high impact but low frequency
D.
Electronic commerce is a primary business driver
Explanation:
Continuous monitoring control initiatives are expensive, so they have to be used in areas where the risk is at itsgreatest level. These areas are the ones with high impact and high frequency of occurrence. Regulations and legislations that require tight IT security measures focus on requiring organizations to establish an IT security governance structure that manages IT security with a risk-based approach, so each organization decides which kinds of controls are implemented. Continuous monitoring is not necessarily a requirement. Measures such as contingency planning are commonly used when incidents rarely happen but have a high impact each time they happen. Continuous monitoring is unlikely to be necessary. Continuous control monitoring initiatives are not needed in all electronic commerce environments. There are some electronic commerce environments where the impact of incidents is not high enough to support the implementation of this kind of initiative.
