In the Reports tab of QRadar, the message "Queued (position in the queue)" indicates that the report is queued for generation. The message provides the position of the report within the generation queue, which helps users understand the report's status and expected generation time​

To identify events that were missed by the Custom Rule Engine (CRE) in IBM Security QRadar SIEM, an analyst would primarily look for "Log Only Events sent to a Data Store" and "High Level Category Unknown Events." Log Only Events are those that are stored directly without being processed by the CRE, indicating they might have been overlooked or not matched by any existing rules. High Level Category Unknown Events are those that do not fit into any of the predefined categories in QRadar, suggesting that the CRE might not have rules to handle or categorize these events properly. These types of events are crucial for analysts to review to ensure that no significant incidents are missed and to refine the rule set for better detection in the future.

The information displayed when pressing “Ctrl + Space” in the search field in the Log Activity tab in QRadar is not explicitly mentioned in the search results. However, in general, this shortcut is often used in various software and platforms to display a list of available commands, functions, or properties. In the context of QRadar, it’s likely that pressing “Ctrl + Space” in the search field would display a list of available AQL (Ariel Query Language) databases, functions, and fields (properties).

The AQL (Ariel Query Language) statement provided would return all fields from the 'events' table where the 'username' column contains the string 'ERS', regardless of case. The 'ILIKE' operator in AQL is used for case-insensitive pattern matching, which means that it will match 'ers', 'Ers', 'ErS', etc​​.

Event Details Page Overview: The Event Details page in QRadar provides in-depth information about each event that is logged. This includes various parameters that help in the analysis and investigation of security incidents.

Configured Parameters:

Event Processor UUID: Unique identifier for the event processor, generally used for internal tracking.

High Level Category: Represents the general category of the event, useful for quick identification and filtering.

Log Source Time: The timestamp indicating when the log was generated by the source.

Log Source Group: A grouping of log sources for organizational purposes.

Relevance of High Level Category: The High Level Category is a crucial parameter found in the Event Details page, as it provides a broad classification of the event type, aiding in quick understanding and categorization of events.

Reference Confirmation: According to IBM QRadar documentation, the High Level Category is prominently featured on the Event Details page, making it the correct answer.

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​​.

By default, QRadar stores payload indexes for a duration of 30 days. This retention period is configurable, allowing administrators to adjust how long specific data is retained based on their requirements​​.

When investigating an offense in QRadar, finding the number of flows or events associated with it can be achieved through the "List Events/Flows" option. This functionality allows analysts to view a detailed list of all the individual events and flows that are related to a specific offense, offering insights into the nature and scope of the activities involved. By examining this list, analysts can better understand the context of the offense, including the types of network traffic and system actions that triggered the security alerts, facilitating a more informed investigation process.
