When an analyst right-clicks on the Source IP or Destination IP that is associated with an offense at the Offense Summary in QRadar, two of the top-level options are DNS Lookup and WHOIS Lookup1. These options provide additional information about the IP address, such as its domain name (DNS Lookup) and registration information (WHOIS Lookup)1.

Understanding Offense Parameters in QRadar: In IBM QRadar, offenses are evaluated and prioritized based on several parameters that determine the significance and potential impact of the security incident.

Key Parameters:

Relevance: Indicates how relevant the event is to the organization's environment.

Severity: Represents the potential damage or impact the event could have on the system.

Credibility: Reflects the likelihood that the event represents a true security incident.

Magnitude Rating Calculation: The magnitude rating is a composite score that is calculated using the relevance, severity, and credibility of an offense. This rating helps security analysts prioritize incidents based on their potential threat level.

Reference Confirmation: According to IBM QRadar documentation, the magnitude rating is the parameter that is derived from the relevance, severity, and credibility of an offense.

Offense Summary Window: Provides a centralized view of offense details.

Event/Flow Count Column: This column displays the number of events (and potentially flows) that contributed to the offense.

Accessing Events: Clicking on the number in this column typically opens a list or detailed view of the associated events.

Vulnerability Scans and Offenses: VA scanners frequently trigger alerts as their activity can resemble malicious behavior.

Host Definitions: This QRadar building block group helps define known hosts, including their attributes and roles on the network.

Adding to Definitions: Including the VA scanner's IP in the host definitions allows QRadar to recognize it and properly categorize its activity.

The default setting for the System Notification dashboard is to display 10 notifications, providing a manageable overview of system alerts and issues. Users can adjust this setting to view fewer or more notifications based on their preferences​​.

Building Blocks in QRadar are foundational elements that are used to construct more complex rules. They are essentially a collection of conditional tests or criteria that define specific behaviors, characteristics, or patterns within the network data but do not, by themselves, trigger any responses or actions when those conditions are met.

Building Blocks are designed to be reused in multiple rules, making rule creation more efficient and standardized. For example, a Building Block might define a set of common malicious IP addresses or unusual traffic patterns. This Building Block can then be incorporated into several different rules that might deal with various types of threats, each of which requires identifying traffic from or to these malicious IPs as part of their logic.

The reusability of Building Blocks ensures that changes to common criteria, such as updating the list of malicious IP addresses, only need to be made in one place. This approach enhances the maintainability and consistency of the rule set within QRadar, making the system more agile and responsive to changes in the threat landscape.

Building Blocks are a powerful feature within QRadar that promote modularity and efficiency in rule creation, helping organizations tailor their threat detection capabilities to their specific needs without requiring actions or responses to be defined within these foundational elements themselves.

In QRadar, when performing a search in the My Offenses or All Offenses tabs, valid values for the Offense Type field include "Any" and "Source IP". "Any" searches all offense sources, while "Source IP" allows for searching offenses with a specific source IP address​​.

Here's why this is the correct statement:

Purpose of the Assets Tab: The Assets tab is QRadar's central repository for information about discovered assets on your network.expand_more Assets include network devices, servers, applications, and more.

Discovery Process: QRadar discovers assets by passively analyzing log and flow data, as well as through active scans if configured.
