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.

ReferencesThe 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.

If the option "Include in my Dashboard" cannot be selected when creating a saved search in IBM QRadar SIEM V7.5, a possible reason is insufficient permissions. Here’s why:

Permissions: The user needs appropriate permissions to add saved searches to the dashboard.

Role-Based Access Control: QRadar uses role-based access control to manage user permissions. The user’s role must include the necessary privileges to modify dashboards.

Verification: Ensure that the user has the correct permissions assigned. This can be checked and adjusted in the user management settings.

ReferencesIBM QRadar SIEM administration guides explain the permissions required for various actions, including adding saved searches to dashboards, and how to configure user roles and permissions.

The primary method used by IBM QRadar to install and manage applications created using the GUI Application Framework Software Development Kit (SDK) is through the REST API interface:

API Endpoint:/api/gui_app_framework

Functionality: This endpoint allows administrators to manage the lifecycle of applications, including installation, updates, and removal.

Integration: Provides seamless integration with the GUI Application Framework, enabling the development and deployment of custom applications within QRadar.

ReferencesThe IBM QRadar API documentation provides details on the/api/gui_app_frameworkendpoint and its usage for managing GUI applications.

To track network bandwidth violations by any application coming from your network source and report on all applications that create traffic along with the amount of data from each IP address, you need to store the IP address, the application, and the amount of data in a reference data collection. The appropriate type of reference data collection for this use case is a "Reference map." Here is why:

Reference Map: A reference map allows you to store key-value pairs where each key is unique. In this context, the key can be the combination of the IP address and the application, and the value can be the amount of data (total bytes).

Data Structure: This structure enables efficient lookups and updates, which is ideal for tracking and reporting bandwidth usage per application per IP address.

Use Case Suitability: The reference map is suitable for scenarios where you need to store and retrieve values based on a specific key, and it supports storing complex data structures efficiently.

This type of reference data collection supports the use case by allowing the storage and retrieval of detailed network traffic information per application and IP address.
