A ORadar administrator creates a new saved search in QRadar and wants to add the search to a dashboard, but the option "Include in my Dashboard" cannot be selected.
What is a possible reason it is unavailable?
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.
Reference IBM 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.
In the QRadar GUI. you notice that no new offenses were generated today. A review of the notifications shows:
MPC: Unable to create new offense. The maximum number of active offenses has been reached.
What is the default value of the maximum number?
In IBM QRadar SIEM V7.5, the default value for the maximum number of active offenses is set to 2500. This limit is in place to manage system performance and ensure efficient processing of security incidents. Here's the detailed information:
Default Setting: The default setting for the maximum number of active offenses is 2500.
Impact: If this limit is reached, QRadar will not generate new offenses until some of the existing offenses are closed or archived.
Configuration: Administrators can adjust this setting based on their organizational needs, but the default value is 2500.
Reference This information is detailed in the QRadar SIEM configuration and tuning guides, which specify default settings and provide instructions for modifying the maximum number of active offenses if necessary.
From which two (2) resources can an administrator download QRadar security content?
Administrators can download QRadar security content from the following two resources:
QRadar Application Repository: This repository contains a wide range of applications, rules, reports, and other content specifically designed for QRadar.
IBM Security App Exchange: A platform where users can find and download security applications, including those for QRadar. It offers a variety of tools to extend and enhance the functionality of QRadar SIEM.
These resources provide curated and validated security content, ensuring that administrators have access to the latest and most effective tools for their security needs.
Reference IBM QRadar documentation and support resources detail the QRadar Application Repository and IBM Security App Exchange as primary sources for downloading and updating QRadar security content.
Which authentication type in QRadar encrypts the username and password and forwards the username and password to the external server for authentication?
TACACS (Terminal Access Controller Access-Control System) authentication is a protocol used in IBM QRadar SIEM V7.5 for authenticating users by forwarding their credentials to an external server. Here's how it works:
Encryption: TACACS encrypts the entire payload of the authentication packet, including the username and password, ensuring secure transmission.
Forwarding Credentials: After encryption, the credentials are forwarded to an external TACACS server, which performs the actual authentication.
Authentication Process: The external server checks the credentials against its database and sends a response back to QRadar indicating whether the authentication is successful or not.
Reference IBM QRadar SIEM documentation explains TACACS authentication in detail, highlighting its secure encryption and external server verification process.
An administrator receives a file with all the vital assets in the company and wants to import this file into QRadar. How must this import file be formatted?
When importing vital asset information into IBM QRadar SIEM V7.5, the import file must be formatted as a CSV file with the following structure:
Format: CSV (Comma-Separated Values)
Fields: The required fields are IP address, Name, Weight, and Description.
IP address: The IP address of the asset.
Name: The name of the asset.
Weight: A numerical value representing the importance or criticality of the asset.
Description: A brief description of the asset.
This format ensures that QRadar can correctly parse and import the asset information, integrating it into its asset database for further analysis and correlation.
Reference IBM QRadar SIEM documentation provides guidelines on the required CSV format for importing asset information, detailing the necessary fields and their order.
