The risk of mishandling alerts identified by an intrusion detection system (IDS) can have serious consequences for an organization's information security. Mishandling alerts could lead to unauthorized access, data theft, or even a complete system shutdown. In order to minimize the risk of mishandling alerts, it is important to have formalized standard operating procedures (SOPs), properly configured IDS sensors, and a well-organized team for operations and monitoring.
Option A suggests that the risk of mishandling alerts is greatest when standard operating procedures are not formalized. This is because without formalized SOPs, there is no clear process in place for handling alerts, which could result in confusion or inconsistency in response. This lack of consistency could result in missed or delayed alerts, or alerts being handled incorrectly, leading to a security breach.
Option B suggests that the risk of mishandling alerts is greatest when the IT infrastructure is diverse. A diverse IT infrastructure could mean that there are multiple IDS sensors in place, each with different configurations and settings. This could make it difficult to manage alerts and ensure that they are being properly handled, increasing the risk of mishandling alerts.
Option C suggests that the risk of mishandling alerts is greatest when IDS sensors are misconfigured. Misconfigured sensors could generate false positives or false negatives, which could result in alerts being ignored or mishandled. This could lead to a security breach, as threats go unnoticed or are not responded to in a timely manner.
Option D suggests that the risk of mishandling alerts is greatest when operations and monitoring are handled by different teams. This is because separate teams could result in miscommunications or misunderstandings about the proper handling of alerts. This could lead to alerts being mishandled or ignored, increasing the risk of a security breach.
Overall, while all of the options could potentially increase the risk of mishandling alerts, option C - misconfigured IDS sensors - presents the greatest risk. Misconfigured sensors could lead to false positives or false negatives, which could cause alerts to be mishandled or ignored, potentially resulting in a security breach.
