Offense chaining is based on which field that is specified in the rule?
D
Explanation:
Offense chaining in IBM Security QRadar SIEM V7.5 is based on the offense index field specified in
the rule. This means that if a rule is configured to use a specific field, such as the source IP address,
as the offense index field, there will only be one offense for that specific source IP address while the
offense is active. This mechanism is crucial for tracking and managing offenses efficiently within the
system.
What QRadar application can help you ensure that IBM GRadar is optimally configured to detect
threats accurately throughout the attack chain?
D
Explanation:
The IBM QRadar Use Case Manager application assists in tuning QRadar to ensure it is optimally
configured for accurate threat detection throughout the attack chain. This application provides
guided tips to help administrators adjust configurations, making QRadar more effective in identifying
and mitigating security threats. The QRadar Use Case Manager plays a significant role in maintaining
the effectiveness of the QRadar deployment.
How can an analyst search for all events that include the keyword "access"?
B
Explanation:
In IBM Security QRadar SIEM V7.5, to search for all events containing a specific keyword such as
"access", an analyst should navigate to the "Log Activity" tab. This section of the QRadar interface is
dedicated to viewing and analyzing log data collected from various sources. By running a quick
search with the "access" keyword in the Log Activity tab, the analyst can filter out events that contain
this term in any part of the log data. This functionality is crucial for identifying specific activities or
incidents within the vast amounts of log data QRadar processes, allowing analysts to quickly hone in
on relevant information for further investigation or action.
What feature in QRadar uses existing asset profile data so administrators can define unknown server
types and assign them to a server definition in building blocks and in the network hierarchy?
C
Explanation:
In IBM Security QRadar SIEM V7.5, the feature that utilizes existing asset profile data to define
unknown server types and assign them to server definitions in building blocks and in the network
hierarchy is known as "Server Discovery." This feature grants permission to discover servers, thereby
enabling administrators to identify and classify various server types within their network
infrastructure, enhancing the overall asset management and security posture.
QRadar analysts can download different types of content extensions from the IBM X-Force Exchange
portal. Which two (2) types of content extensions are supported by QRadar?
A, E
Explanation:
QRadar supports different types of content extensions that can be downloaded from the IBM X-Force
Exchange portal. Among the supported content extensions are "Custom Functions" and "Offenses."
These extensions allow for enhanced functionality and customization within QRadar, providing users
with the ability to tailor the system to specific security needs and requirements.
What right-click menu option can an analyst use to find information about an IP or URL?
D
Explanation:
To find information about an IP or URL within QRadar, analysts can use the right-click menu option
"X-Force Exchange Lookup." This option is available when right-clicking an IP address or URL from the
Offenses tab or event details windows, providing direct access to the X-Force Exchange interface for
detailed threat intelligence and contextual information.
On the Offenses tab, which column explains the cause of the offense?
B
Explanation:
On the Offenses tab within QRadar, the "Offense Type" column explains the cause of the offense. The
offense type is determined by the rule that triggered the offense, and it dictates the kind of
information displayed in the Offense Source Summary pane. This helps analysts understand the
nature and origin of the offense, facilitating more effective investigation and response actions.
When using the Dynamic Search window on the Admin tab, which two (2) data sources are available?
AC
Explanation:
In the Dynamic Search window on the Admin tab of QRadar, the available data sources include
"Assets" and "Offenses." These options allow administrators and analysts to construct queries based
on asset information or offense data, enabling targeted searches and analyses tailored to specific
security concerns within the organization.
How can adding indexed properties to QRadar improve the efficiency of searches?
A
Explanation:
Adding indexed properties to QRadar can significantly improve the efficiency of searches by reducing
the size of the data set required to locate matches for non-indexed search values. Indexing creates
references to unique terms in the data and their locations, which means that the search engine can
filter the data set by indexed properties first, eliminating irrelevant portions of the data set and
thereby reducing the overall volume of data that needs to be searched.
Which type of rule should you use to test events or (lows for activities that are greater than or less
than a specified range?
D
Explanation:
Threshold rules in QRadar are designed to test events or flows for activities that are greater than or
less than a specified range. These rules are particularly useful for detecting significant changes such
as bandwidth usage variations, failed services, changes in the number of connected users, and large
outbound data transfers. By setting acceptable limits within threshold rules, administrators can
effectively monitor for and respond to abnormal activities within the network.
Which parameters are used to calculate the magnitude rating of an offense?
B
Explanation:
The magnitude rating of an offense in IBM Security QRadar SIEM V7.5 is calculated based on three
key parameters: severity, relevance, and credibility. Severity indicates the level of threat, relevance
determines the offense's impact on the network, and credibility reflects the integrity of the offense
as determined by the credibility rating configured in the log source. This combination of factors helps
prioritize offenses and guide analysts on which ones to investigate first.
Reports can be generated by using which file formats in QRadar?
A
Explanation:
QRadar supports generating reports in various file formats, including PDF, HTML, XML, and XLS.
These formats provide flexibility in how reports are viewed and shared, catering to different needs
and preferences for report presentation and analysis.
The Use Case Manager app has an option to see MITRE heat map.
Which two (2) factors are responsible for the different colors in MITRE heat map?
C, D
Explanation:
The MITRE heat map in the Use Case Manager app within QRadar uses several factors to determine
the colors displayed, among which the number of rules mapped to MITRE ATT&CK tactics and
techniques and the level of mapping confidence are crucial. These factors help visualize the coverage
and reliability of rule mappings against the comprehensive MITRE ATT&CK framework, aiding in the
identification of potential gaps or areas for improvement in threat detection capabilities.
In QRadar. what do event rules test against?
B
Explanation:
Event rules in QRadar test against incoming log source data processed in real time by the QRadar
Event Processor. This real-time processing enables QRadar to analyze and respond to security events
as they occur, enhancing the system's ability to detect and mitigate threats promptly.
What two (2) guidelines should you follow when you define your network hierarchy?
B, E
Explanation:
When defining the network hierarchy in QRadar, it is recommended to organize systems and
networks by role or similar traffic patterns to differentiate network behavior effectively. Additionally,
it is advised not to configure a network group with more than 15 objects to avoid difficulties in
viewing detailed information for each object and to ensure efficient management of network groups.
