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.

QRadar event data is stored in the Ariel database on the Event Processor and any attached Data Nodes. The Event Processor is responsible for processing incoming events, performing correlation, and storing the event data. The attached Data Nodes provide additional storage capacity and can be used to extend the storage available to the Event Processor.

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.

Reference The IBM QRadar API documentation provides details on the /api/gui_app_framework endpoint and its usage for managing GUI applications.

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.

The default user role defined in QRadar is 'QRadar Users'. Here's a detailed explanation:

User Roles in QRadar: QRadar has a role-based access control system to manage user permissions and access levels. This ensures that users can only access and perform actions within their assigned roles.

Default Role - QRadar Users: The 'QRadar Users' role is the default role assigned to new users. This role typically includes basic permissions needed to access and use QRadar features without administrative privileges.

Permissions: Users with the 'QRadar Users' role can view and analyze security data, but they might have limited access to configuration settings and administrative functions.

Assigning default roles helps streamline user management and ensures that new users have the necessary access to perform their tasks.
