How can adding indexed properties to QRadar improve the efficiency of searches?
Adding indexed properties to QRadar can significantly improve the efficiency of searches by reducing the size of the data set required to locate matches for non-indexed search values. Indexing creates references to unique terms in the data and their locations, which means that the search engine can filter the data set by indexed properties first, eliminating irrelevant portions of the data set and thereby reducing the overall volume of data that needs to be searched.
Which reference set data element attribute governs who can view its value?
The Domain attribute governs who can view the value of a reference set data element, ensuring that only users with appropriate domain access or tenant assignments can view the data. This is essential for maintaining data visibility and access control within a multi-tenant QRadar environment.
What QRadar application can help you ensure that IBM GRadar is optimally configured to detect threats accurately throughout the attack chain?
The IBM QRadar Use Case Manager application assists in tuning QRadar to ensure it is optimally configured for accurate threat detection throughout the attack chain. This application provides guided tips to help administrators adjust configurations, making QRadar more effective in identifying and mitigating security threats. The QRadar Use Case Manager plays a significant role in maintaining the effectiveness of the QRadar deployment.
When examining lime fields on Event Information, which one represents the time QRadar received the raw event?
The 'Start Time' timestamp represents when an event is received by a QRadar Event Collector, marking the moment QRadar first becomes aware of the event. This is crucial for understanding the timing of event processing and potential delays in the event pipeline.
