C1000-156 IBM Security QRadar SIEM V7.5 Administration Questions and Answers

Similar to the previous question, when a QRadar administrator creates a new saved search and wants it to be the first search displayed upon opening the Log Activity tab, the correct option to enable is "Set as Default." Here's the detailed process:

Saved Search Creation: The administrator specifies the search parameters and criteria to create a new saved search.

Enabling Default Setting: By selecting the "Set as Default" checkbox, the administrator ensures that this search will automatically run and display when the Log Activity tab is accessed.

Utility: This option is particularly useful for quickly accessing the most relevant data without needing to manually select and run the saved search each time.

Setting a default search helps maintain focus on critical security events by providing immediate access to predefined search results.

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.

Therecon connectcommand in IBM QRadar SIEM V7.5 allows administrators to run a specific command inside a specific container, given an app ID or a combination of workload, service, and container. Here’s how it works:

Command:recon connect

Function: This command connects to a specified container and allows the execution of commands within that container.

Usage: Administrators use this command to manage and troubleshoot applications running in isolated environments (containers) within QRadar.

ReferencesThe QRadar administration and support guides detail the usage of therecon connectcommand for managing containerized applications.

In IBM QRadar SIEM V7.5, managing what functions a user can access is crucial for maintaining security and ensuring that users have appropriate permissions. TheSecurity Profileoption is used to manage these access controls. Here’s how it works:

Security Profile: Defines the specific permissions and roles assigned to users, dictating what actions they can perform within QRadar. This includes access to various modules, dashboards, and functionalities.

User Role: While related, user roles are more about grouping users with similar permissions rather than defining individual access.

Admin Role: Typically reserved for users with administrative privileges but does not manage the specific functions users can access.

Security Options: This is not a relevant option for managing user access to QRadar functions.

ReferencesIBM QRadar SIEM V7.5 documentation details how security profiles are configured and managed, providing comprehensive steps on assigning and modifying user access based on roles and profiles.

When using the DSM (Device Support Module) Editor in IBM QRadar to map an event to an OID (Object Identifier), the Event ID field is mandatory. The Event ID uniquely identifies the event within QRadar and is essential for ensuring that the correct event data is associated with the appropriate OID. This mapping process allows QRadar to properly categorize and handle events based on their unique identifiers.

Reconfiguring your IBM QRadar environment to a distributed deployment is considered under the following circumstances:

Capacity Limits: When the processing or storage requirements of your QRadar environment exceed the capacity of a single appliance, it becomes necessary to distribute the workload across multiple systems.

Performance Improvement: A distributed deployment allows for better load balancing and performance optimization by distributing event and flow processing tasks.

Scalability: As your organization's data volume grows, a distributed deployment ensures that QRadar can handle the increased load without degradation in performance.

ReferencesIBM QRadar SIEM administration guides discuss the considerations and benefits of moving to a distributed deployment when scaling beyond the capacity of a single appliance.

In a single domain QRadar deployment, the IP addresses considered local are those that are defined in the network hierarchy. Here is a detailed explanation:

Network Hierarchy: QRadar uses a network hierarchy to define and manage IP addresses within the organization. This hierarchy allows QRadar to understand which IP addresses are part of the internal network and which are external.

Defining Local IP Addresses: Any IP address that is specified within the network hierarchy is considered local. This includes all the subnets and IP ranges that are part of the internal network.

Purpose: By defining the network hierarchy, QRadar can effectively differentiate between internal (local) and external (non-local) traffic, enabling more accurate detection and correlation of security events.

This approach helps in identifying suspicious activities by comparing the source and destination of traffic against the defined internal network.

The primary method used by IBM QRadar SIEM V7.5 to alert users to problems is through System Notifications. Here’s how it works:

System Notifications: These are alerts generated by QRadar to inform users of various issues, such as system performance problems, license issues, or security incidents.

Visibility: Notifications are prominently displayed in the QRadar GUI, ensuring that administrators and users can quickly identify and respond to any problems.

Customization: Users can configure notification settings to receive alerts for specific types of issues, ensuring they stay informed about critical aspects of the system’s health and performance.

ReferencesIBM QRadar SIEM documentation outlines the use of System Notifications as theprimary method for alerting users to issues, detailing how to configure and manage these alerts.

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.

ReferencesThe QRadar SIEM administration guide provides detailed steps on accessing and managing license information, including the giveback rate, under the Admin tab.

To see all of the events from a particular log source in the Log Activity tab, a user must have the appropriate permissions set in their security profile. The most restrictive permissions needed are:

Security Profile Inclusion: The log source must be included in the user's security profile. This means the user must have explicit permission to access events from this log source.

Permissions to Networks and Log Sources: The user's security profile must also include permissions to both Networks and Log Sources. This ensures the user has the necessary access to view events related to the specified log source within the network context.

These permissions are crucial to control and restrict access, ensuring users can only view data they are authorized to see while maintaining security and privacy within the system.
