When will events or flows stop contributing to an offense?
In IBM QRadar SIEM V7.5, events or flows stop contributing to an offense when the offense becomes dormant. Here's how it works:
Dormant Offense: An offense becomes dormant when there is no new activity contributing to it for a specified period. This indicates that the threat or incident has not had any further related events or flows.
Contribution Stoppage: Once an offense is marked as dormant, no additional events or flows are added to it, which helps in managing the offense lifecycle and resources within QRadar.
This behavior helps in distinguishing between active and inactive threats, allowing security analysts to focus on ongoing incidents.
Reference The QRadar SIEM administration and user guides provide detailed explanations of offense management, including the conditions under which offenses become dormant and how this affects event and flow contributions.
Which three (3) resource restriction types are available in QRadar?
IBM QRadar SIEM V7.5 provides several types of resource restriction mechanisms to manage access control and data visibility. The three main types are:
Role-based restrictions: These restrictions limit what actions users can perform based on their assigned roles. Each role has specific permissions that dictate access to different functionalities and data within QRadar.
Tenant-based restrictions: This type of restriction is used in multi-tenant environments, where different tenants (organizational units) need to have isolated views and access to their data. Tenant-based restrictions ensure that users from one tenant cannot access data from another tenant.
Domain-based restrictions: Domains in QRadar are used to segment data logically. Domain-based restrictions control which data is visible to users based on the domains they have been granted access to.
These restriction types ensure that access control is granular and adheres to organizational security policies.
Reference IBM QRadar SIEM documentation outlines the use of role-based, tenant-based, and domain-based restrictions for managing access control and data visibility.
Which command does an administrator run in QRadar to get a list of installed applications and their App-ID values output to the screen?
To get a list of installed applications and their App-ID values in IBM QRadar SIEM, the administrator can run the following command:
Command: /opt/qradar/support/deployment_info.sh
Function: This command outputs detailed information about the current deployment, including a list of all installed applications and their associated App-ID values.
Usage: The administrator executes this command in the terminal, and the information is displayed on the screen.
Reference IBM QRadar SIEM V7.5 administration guides include this command as a standard tool for retrieving deployment information, including details about installed applications and their IDs.
When creating an identity exclusion search, what time range do you select?
When creating an identity exclusion search in IBM QRadar SIEM V7.5, the time range selected is 'Real time (streaming).' This setting ensures that the search continuously monitors and excludes identities in real-time as data is ingested. Here's the process:
Real-time Monitoring: Continuously updates the search results based on incoming data, providing immediate exclusion of specified identities.
Streaming Data: Processes data in a live stream, ensuring that the exclusion criteria are applied instantaneously as new events occur.
Reference The setup and configuration of identity exclusion searches are detailed in the QRadar SIEM administration guides, highlighting the importance of real-time streaming for effective identity management.
In which QRadar section can the administrator view the license giveback rate?
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.
