C1000-162 Exam Dumps - IBM Security QRadar SIEM V7.5 Analysis

Understanding Login ID Verification: Verifying whether a login ID is assigned to a user involves checking a mapping of login IDs to user records. This process requires a data structure that can map unique login IDs to user information.

Suitable Reference Data Collection:

Reference Map of Maps: Used for storing nested key-value pairs but more complex than needed for simple login ID verification.

Reference Login: Not a standard reference data collection in QRadar.

Reference Map: Ideal for mapping login IDs (unique keys) to user details (values).

Reference Set: Stores unique values but does not map them to any associated data.

Using Reference Map: The reference map is the appropriate choice as it allows for direct mapping of each login ID to corresponding user details. This structure facilitates efficient verification processes.

Reference Confirmation: According to IBM QRadar documentation, using a reference map to associate login IDs with user details is a standard approach for verifying user assignments.

References:

IBM QRadar documentation on reference data collections indicates the use of reference maps for mapping unique identifiers like login IDs to user records.

IOCs and Reference Sets: Reference sets are specifically designed to store lists of Indicators of Compromise (IOCs) like IP addresses, domain names, file hashes, etc.

Correlation and Matching: QRadar can match events and flows against data in reference sets, triggering rules or alerts when suspicious activity is detected.

QRadar will mark an Event offense as dormant if no new events or flows occur within 30 minutes. However, if QRadar did not process any events within 4 hours, this also triggers the offense to become dormant. Once dormant, the offense remains in this state for 5 days unless new events or flows are added​​​​.

Report Data Source: To generate a report focused on offense data, you must explicitly select "Offense" as the data source. This tells QRadar to structure the report around offense information.

Edit Search: The "Edit Search" interface often provides the ability to configure report generation.

When deleting a generated content report in QRadar, all reports that were generated from the report template are deleted, but the report template itself is retained. This ensures that the structure for generating future reports remains intact, while only the instances of reports generated from that template are removed​​.
