C1000-156 Exam Dumps : IBM Security QRadar SIEM V7.5 Administration

When creating an identity exclusion search in IBM QRadar SIEM V7.5, the time range selected is "Real time (streaming)." This setting ensures that the search continuously monitors and excludes identities in real-time as data is ingested. Here’s the process:

Real-time Monitoring: Continuously updates the search results based on incoming data, providing immediate exclusion of specified identities.

Streaming Data: Processes data in a live stream, ensuring that the exclusion criteria are applied instantaneously as new events occur.

ReferencesThe setup and configuration of identity exclusion searches are detailed in the QRadar SIEM administration guides, highlighting the importance of real-time streaming for effective identity management.

To ensure that a rule in IBM QRadar SIEM V7.5 does not send an email more than 10 times in a 24-hour period, the "response limiter" can be used. Here’s how it works:

Response Limiter: This feature limits the number of times a rule action (such as sending an email) can be executed within a specified timeframe.

Configuration: Set the response limiter to a maximum of 10 actions in 24 hours.

Implementation: Apply the response limiter to the rule, ensuring that even if the rule conditions are met multiple times, the email will only be sent up to the specified limit.

ReferencesIBM QRadar SIEM documentation on rule management and tuning includes detailed instructions on using the response limiter to control the frequency of rule actions.

The primary method used by IBM QRadar SIEM V7.5 to alert users to problems is through System Notifications. Here’s how it works:

System Notifications: These are alerts generated by QRadar to inform users of various issues, such as system performance problems, license issues, or security incidents.

Visibility: Notifications are prominently displayed in the QRadar GUI, ensuring that administrators and users can quickly identify and respond to any problems.

Customization: Users can configure notification settings to receive alerts for specific types of issues, ensuring they stay informed about critical aspects of the system’s health and performance.

ReferencesIBM QRadar SIEM documentation outlines the use of System Notifications as theprimary method for alerting users to issues, detailing how to configure and manage these alerts.
