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.

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.

The default port for the first NetFlow flow source configured in QRadar is 2055. Here's a detailed explanation:

NetFlow Flow Sources: NetFlow is a network protocol developed by Cisco for collecting IP traffic information. QRadar can be configured to receive NetFlow data to monitor and analyze network traffic.

Default Port: When setting up the first NetFlow flow source in QRadar, the system uses port 2055 by default. This is a standard port commonly used for NetFlow traffic.

Configuration: During the configuration process, this default port can be used to receive data from devices that export NetFlow data, such as routers and switches.

Using port 2055 helps standardize the setup process and ensures compatibility with most NetFlow-enabled devices.

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.

To configure a log source in IBM QRadar SIEM V7.5 to provide events to different domains, administrators can use custom properties. Here's how it works:

Custom Properties: Create and configure custom properties to tag events with specific domain information.

Assigning Events: When events are ingested from a log source, these custom properties can be used to dynamically assign events to different domains based on predefined criteria.

Domain Management: This approach allows flexibility in managing and segregating data from a single log source across multiple domains, ensuring that each domain receives the relevant events.

Reference The configuration of custom properties for domain assignment is detailed in the QRadar SIEM administration guides, providing step-by-step instructions for setting up and using custom properties for domain management.
