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

In IBM QRadar SIEM V7.5, the default value for the maximum number of active offenses is set to 2500. This limit is in place to manage system performance and ensure efficient processing of security incidents. Here’s the detailed information:

Default Setting: The default setting for the maximum number of active offenses is 2500.

Impact: If this limit is reached, QRadar will not generate new offenses until some of the existing offenses are closed or archived.

Configuration: Administrators can adjust this setting based on their organizational needs, but the default value is 2500.

ReferencesThis information is detailed in the QRadar SIEM configuration and tuning guides, which specify default settings and provide instructions for modifying the maximum number of active offenses if necessary.

In IBM QRadar, system notifications are crucial for alerting administrators about various events and statuses that require attention. The rule name for system notifications is "System: Notification". Here is a detailed explanation of how it functions and how to find and edit this rule:

Accessing the Offenses Section: To view and manage rules related to offenses, an administrator needs to open the Offenses section in the QRadar console.

Navigating to Rules: Within the Offenses section, there is a subsection for rules. This is where all the predefined and custom rules are listed.

Editing System Notification Rules: The specific rule for system notifications is named "System: Notification". This rule is responsible for generating notifications based on system events and statuses.

Customizing the Rule: By selecting and editing this rule, administrators can adjust the conditions and actions associated with system notifications, ensuring they are tailored to the specific needs and policies of the organization.

This rule is essential for maintaining awareness of system events and ensuring that potential issues are promptly addressed.

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.
