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.

The QRadar Threat Intelligence app uses open standards to integrate and utilize threat intelligence feeds effectively. The two key standards used are:

TAXII (Trusted Automated eXchange of Indicator Information): This is an application layer protocol used for exchanging cyber threat intelligence over HTTPS. It enables the sharing of threat information across different systems and organizations.

STIX (Structured Threat Information eXpression): This is a standardized language used for representing structured cyber threat information. STIX enables the consistent and machine-readable representation of threat data, facilitating the integration and analysis of threat intelligence.

These standards ensure that threat intelligence data is formatted and exchanged in a consistent and interoperable manner, enhancing the overall effectiveness of the threat intelligence processes in QRadar.

ReferencesThe IBM QRadar SIEM documentation and threat intelligence app configuration guides describe the use of TAXII and STIX for integrating threat intelligence feeds.

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.
