Final answer:
ICS impacts incident management efforts by standardizing response protocols, revealing that increased cognitive load can lead to decision-making errors, as demonstrated by studies in human factors psychology and real-world incidents like Target's 2013 data breach.
Step-by-step explanation:
The Incident Command System (ICS) impacted incident management efforts by providing a standard structure and approach to coordinating and managing emergency responses, which is critical to handle situations effectively and efficiently. The case of the banking institution in Brazil involves human factors psychology research that highlights how the volume of decisions can affect the accuracy of threat detection, implying the importance of robust incident management.
Further, the example of Target's 2013 data breach illustrates a real-world incident where ICS could have potentially mitigated the consequences by providing clearer guidance and protocols for interpreting security threats. As cognitive load increases in high-stress situations, such as the management of security breaches, decision-makers are prone to errors, specifically in false positive identifications of threats.
