Free IBM Certification Security QRadar, Associate Analyst Question and Answers β Questions and Answers
Question 1: What distinguishes a flow from an incident most significantly?
- Flows only contribute to local correlated rules, while events are global.
- Events allow for the creation of custom properties, but flows cannot.
- Events can be forwarded to another destination, but flows cannot.
- Events occur at a moment in time while flows have a duration. (Correct answer)
Correct answer: Events occur at a moment in time while flows have a duration.
In SIEM systems like QRadar, the key distinction between an event and a flow lies in their temporal characteristics. An event represents a discrete occurrence that happens at a specific moment in time, such as a single login attempt or an error message. In contrast, a flow represents a network communication session or a series of related packets that has a duration, with a defined start time, end time, and total length.
Question 2: Which QRadar rule is capable of identifying a probable data loss?
- Apply Potential data loss on flows which are detected by the local system and when the source bytes is greater than 200000 and when at least 5 flows are seen with the same Source IP, Destination Port Destination IP in 12 minutes (Correct answer)
- Apply Potential data loss on events which are detected by the local system and when the event category for the event is one of the following Authentication and when any of Username are contained in any of Terminated_User
- Apply Potential data loss on flows which are detected by the local system and when at least 1000 flows are seen with the same Destination IP and different source in 2 minutes
- Apply Potential data loss on event of flows which are detected by the local system and when any IP is part of any of the following XForce premium Premium_Malware
Correct answer: Apply Potential data loss on flows which are detected by the local system and when the source bytes is greater than 200000 and when at least 5 flows are seen with the same Source IP, Destination Port Destination IP in 12 minutes
This QRadar rule is effective for detecting potential data loss by identifying suspicious patterns in network flows. It looks for multiple (at least 5) large data transfers (source bytes > 200000) originating from the same source IP to the same destination IP and port within a short period (12 minutes). This combination of high volume, frequency, and consistent communication pattern is a strong indicator of bulk data exfiltration or unauthorized data movement.
Question 3: Which fundamental building blocks does the Report Wizard use to assist in producing a report?
- Pagination Option, Orientation, Date
- Report Classification, Time, Date
- Container, Orientation, Layout
- Layout, Container, Content (Correct answer)
Correct answer: Layout, Container, Content
The QRadar Report Wizard uses fundamental building blocks to structure and present information effectively. These include the Layout, which defines the overall arrangement and structure of the report; Containers, which are sections used to group related data within the layout; and Content, which refers to the actual data, charts, and tables displayed within those containers. These elements work together to organize and visualize the desired report information.
Question 4: What kinds of information are provided by log sources?
- Router configuration exports.
- Flows generated by users
- User login actions (Correct answer)
- Operating system updates
Correct answer: User login actions
Log sources, such as operating systems, applications, firewalls, and servers, generate event data that provides granular details about activities occurring within a system or network. User login actions are a prime example of the information provided by log sources, detailing successful or failed attempts, the user involved, the source IP, and the timestamp. This data is crucial for security monitoring, auditing, and incident response.
Question 5: What list solely contains Rule Actions?
- Modify Severity; Send to Forwarding Destinations; Drop the Detected Event; Ensure the detected event is part of an offense.
- Modify Credibility; Send SNMP trap; Drop the Detected Event; Dispatch New Event. (Correct answer)
- Modify Credibility; Annotate Event; Send to Forwarding Destinations; Dispatch New Event.
- Modify Severity; Annotate Event; Drop the Detected Event; Ensure the detected event is part of an offense.
Correct answer: Modify Credibility; Send SNMP trap; Drop the Detected Event; Dispatch New Event.
QRadar rule actions define the automated responses and modifications that occur when a rule's conditions are met. The options listed in B are all valid rule actions: 'Modify Credibility' adjusts the trustworthiness of an event or offense; 'Send SNMP trap' dispatches an alert to an external monitoring system; 'Drop the Detected Event' prevents further processing or storage of the event; and 'Dispatch New Event' generates a new event based on the rule's findings.
Question 6: Where can you find events connected to a certain crime?
- Under Log Activity, search for Events associated with an Offense
- Offenses Tab and Event List window
- Dashboard and List of Events window
- Offense Summary Page and List of Events window (Correct answer)
Correct answer: Offense Summary Page and List of Events window
In QRadar, when investigating a security offense, the most direct way to access the underlying events that contributed to it is through the Offense Summary Page. This page provides an overview of the offense, and from there, you can navigate to the 'List of Events' window. This window displays all the individual events that triggered or were correlated with that specific offense, providing essential context for investigation.
Question 7: What different timestamps are connected to a flow?
- First Packet Time, Storage Time, Log Source Time, End Time
- First Packet Time, Log Source Time, Last Packet Time
- First Packet Time, Storage Time, Last Packet Time (Correct answer)
- First Packet Time, Storage Time, Log Source Time
Correct answer: First Packet Time, Storage Time, Last Packet Time
Network flows in QRadar are characterized by several timestamps that provide a comprehensive temporal context for the communication. The 'First Packet Time' indicates when the flow began, and the 'Last Packet Time' marks when the final packet of that flow was observed. The 'Storage Time' refers to when the flow record was processed and stored by the QRadar system, which can differ slightly from the actual network times due to processing delays.
Question 8: What does an event with a Low Level Category of Unknown on an existing log in QRadar mean?
- That the event was parsed, but not mapped to an existing QRadar category (Correct answer)
- That event was from a device that is not supported by QRadar
- That event arrived out of order from the original device
- That event could not be parsed
Correct answer: That the event was parsed, but not mapped to an existing QRadar category
In QRadar, a Device Support Module (DSM) is responsible for parsing raw log data. If an event from an existing log source has a Low Level Category of 'Unknown,' it means that QRadar successfully parsed the event and extracted its fields but could not map it to any of its predefined categories. This often indicates that the log source is sending a new or unusual event type that requires custom parsing or category mapping within the DSM.
Question 9: What role does the Device Support Module (DSM) perform in QRadar?
- Parses event information for SIEM products received from external sources (Correct answer)
- Provides Vendor specific configuration information
- Unites data received from logs
- Scans log information based on a set of rules to output offenses
Correct answer: Parses event information for SIEM products received from external sources
The Device Support Module (DSM) in QRadar plays a crucial role in processing event information. Its primary function is to parse raw event data received from various external log sources, such as firewalls, servers, and applications. The DSM translates the device's native log format into a common, structured format that QRadar can understand and process, enabling effective correlation, searching, and reporting within the SIEM.
Question 10: Which QRadar component enables more data to be left uncompressed, hence speeding up the search speed during a deployment?
- Qradar Event Processor
- QRadar Event Collector
- QRadar Data Node (Correct answer)
- QRadar Flow Processor
Correct answer: QRadar Data Node
The QRadar Data Node is a component specifically designed to expand storage capacity and improve search performance within a QRadar deployment. It stores event and flow data, and critically, it allows for more data to be left uncompressed. While compression saves disk space, uncompressed data can be searched significantly faster, directly contributing to accelerated search speeds, especially for large datasets and complex queries.
Question 11: A reference table can be used to store and output a mapping from a username to a users manager for use in searches and reports. What system could be employed to do this?
- Reference Table lookup values are automatically used whenever a saved search is run.
- Quick Search filters can select users based on their managerβs name.
- Reference Table lookup values can be accessed in an advanced search. (Correct answer)
- Reference Table lookup values can be accessed as custom event properties.
Correct answer: Reference Table lookup values can be accessed in an advanced search.
QRadar Reference Tables are used to store contextual information, such as mappings from usernames to managers. These lookup values are highly valuable and can be directly accessed and utilized within advanced searches using the Ariel Query Language (AQL). This capability allows security analysts to enrich event and flow data with custom context, enabling more sophisticated filtering, correlation, and reporting based on the information stored in the reference tables.
Question 12: How is the magnitude of an event determined?
- As a weighted mean of the three properties Severity, Credibility and Importance of the Event
- As a weighted mean of the three properties Severity, Credibility and Relevance of the Event (Correct answer)
- As the sum of the three properties Severity, Credibility and Importance of the Event
- As the sum of the three properties Severity, Credibility and Relevance of the Event
Correct answer: As a weighted mean of the three properties Severity, Credibility and Relevance of the Event
In QRadar, the magnitude of an event is a calculated score that represents its overall importance and potential impact. It is determined as a weighted mean of three key properties: the Severity of the event (how serious it is), the Credibility of the event source (its trustworthiness), and the Relevance of the affected asset or user (its importance). This weighted calculation provides a comprehensive measure to prioritize events for investigation.
Question 13: What saved searches are permitted to appear on the Dashboard?
- Network Activity and Risk saved searches
- User and Vulnerability saved searches
- Asset and Network saved searches
- Event and Flow saved searches (Correct answer)
Correct answer: Event and Flow saved searches
The QRadar Dashboard is designed to provide a high-level, real-time overview of security posture. It primarily displays widgets that visualize data derived from Event and Flow saved searches. These searches retrieve and aggregate both real-time and historical event and network flow data, allowing users to monitor key metrics, identify trends, and quickly assess security incidents directly from the dashboard interface.
Question 14: A specific Category of Events connected with the Offense can be looked into while on the Offense Summary page. To view them, where should a security analyst click?
- Right Click on Categories and choose Filter on Network Activity
- Click on Events, then filter on Flows
- Highlight the Category and click the Events icon (Correct answer)
- Scroll down to Categories and view Top 10 Source IPs
Correct answer: Highlight the Category and click the Events icon
On the QRadar Offense Summary page, to investigate the specific events associated with a particular category that contributed to the offense, a security analyst would typically highlight or select that category. After selecting the category, clicking on the 'Events' icon or button will filter and display all the individual events belonging to that chosen category, providing a focused view for deeper analysis and investigation.
Question 15: What kind of search retrieves particular fields from the events, flows, and simarc tables using a structured query language?
- Quick Search
- Advanced Search (Correct answer)
- Add Filter
- Asset Search
Correct answer: Advanced Search
An Advanced Search in QRadar utilizes the Ariel Query Language (AQL), which is a powerful, structured query language. This allows users to retrieve specific fields from event, flow, and other system tables (like `simarc`) with high precision. Advanced searches enable complex filtering, aggregation, and correlation capabilities, going beyond the simpler options of a Quick Search to perform in-depth data analysis and forensic investigations.
Question 16: How many supported dashboards can one user have at once?
- 1023
- 255 (Correct answer)
- 25
- 10
Correct answer: 255
QRadar imposes specific limits on various configurations to ensure optimal system performance and manageability. For user-created dashboards, a single user is permitted to have up to 255 supported dashboards at once. This limit helps in organizing and accessing relevant security information efficiently without overwhelming the system or the user interface with an excessive number of dashboards.
