In IBM QRadar SIEM V7.5, the license giveback rate can be viewed in the License Pool Management section. Here's the step-by-step process:

Access Admin Tab: The administrator needs to navigate to the Admin tab in the QRadar GUI.

License Pool Management: Under the Admin tab, there is an option for License Pool Management.

View License Giveback Rate: Within the License Pool Management section, the administrator can view details about license usage, including the giveback rate.

Reference The QRadar SIEM administration guide provides detailed steps on accessing and managing license information, including the giveback rate, under the Admin tab.

To check an IP address against the Spam X-Force category with a confidence greater than 3 using an advanced search query in QRadar, the correct query format is:

Query Structure: select * from events where XF0RCE_IP_C0NFIDENCE('Malware',sourceip)>3

Components:

select * from events: This part of the query selects all events from the QRadar events database.

where XF0RCE_IP_C0NFIDENCE('Malware',sourceip)>3: This filter checks if the source IP address has a confidence level greater than 3 for being associated with malware according to the X-Force category.

This query is designed to filter out and display events where the source IP is identified with high confidence as being associated with malicious activity.

Reference The syntax and usage of advanced search queries are detailed in the IBM QRadar SIEM search and analytics guides, providing specific examples for utilizing X-Force threat intelligence data.

IBM QRadar SIEM supports various types of custom property expressions to allow users to extract and parse data from logs in flexible and powerful ways. Among the supported custom property expression types, Regex, JSON, and LEEF are frequently utilized:

Regex (Regular Expressions): Regular expressions are a powerful tool used for pattern matching and extraction in text. In QRadar, regex can be used to create custom properties that parse specific patterns from log data, allowing for detailed and precise data extraction.

JSON (JavaScript Object Notation): JSON is a widely used data interchange format that is lightweight and easy to read and write. QRadar supports JSON expressions to parse and extract structured data from logs formatted in JSON.

LEEF (Log Event Extended Format): LEEF is a log format used by various devices to structure log data in a consistent manner. QRadar can utilize LEEF expressions to extract data from logs that use this format.

These types of expressions enhance QRadar's ability to handle diverse log formats and enable more accurate and efficient data analysis.

To include geographic data updates from MaxMind in IBM QRadar SIEM V7.5, the following two pieces of information from the MaxMind account are required:

API Key: This key is used to authenticate and authorize access to the MaxMind services, ensuring that QRadar can request and receive geographic data updates.

License Key: This key is associated with the MaxMind account and allows QRadar to utilize the licensed geographic data for enhanced location-based analysis.

These keys ensure that the data integration is secure and that the usage complies with MaxMind's licensing agreements.

Reference IBM QRadar SIEM documentation specifies the API key and license key as necessary credentials for integrating MaxMind geographic data, detailed in the setup and configuration sections.

In QRadar, when evaluating domain criteria based on an event, the precedence order for domain assignment if the event does not match the domain definition for custom properties is as follows:

Log Source: The first criterion checked is the log source. Each event is associated with a log source, and the domain is determined based on this source.

Log Source Group: If the log source does not provide a domain match, the next criterion is the log source group. Log sources can be grouped together, and domain definitions can be applied at the group level.

Event Collector or Data Gateway: If neither the log source nor the log source group provides a match, QRadar checks the event collector or data gateway for a domain definition.

DDS (Data Domain Service): As the final step, if no other criteria match, the DDS is used to assign the default domain.

This order of precedence ensures that the most specific criteria are checked first before falling back to more general criteria, ensuring accurate domain assignment for events.
