IBM C1000-156 IBM Security QRadar SIEM V7.5 Administration Exam Practice Test

Answer : D

To check an IP address against the Spam X-Force category with a confidence greater than 3 using an advanced search query in QRadar, the correct query format is:

Query Structure: select * from events where XF0RCE_IP_C0NFIDENCE('Malware',sourceip)>3

Components:

select * from events: This part of the query selects all events from the QRadar events database.

where XF0RCE_IP_C0NFIDENCE('Malware',sourceip)>3: This filter checks if the source IP address has a confidence level greater than 3 for being associated with malware according to the X-Force category.

This query is designed to filter out and display events where the source IP is identified with high confidence as being associated with malicious activity.

Reference The syntax and usage of advanced search queries are detailed in the IBM QRadar SIEM search and analytics guides, providing specific examples for utilizing X-Force threat intelligence data.

Answer : B, C

To include geographic data updates from MaxMind in IBM QRadar SIEM V7.5, the following two pieces of information from the MaxMind account are required:

API Key: This key is used to authenticate and authorize access to the MaxMind services, ensuring that QRadar can request and receive geographic data updates.

License Key: This key is associated with the MaxMind account and allows QRadar to utilize the licensed geographic data for enhanced location-based analysis.

These keys ensure that the data integration is secure and that the usage complies with MaxMind's licensing agreements.

Reference IBM QRadar SIEM documentation specifies the API key and license key as necessary credentials for integrating MaxMind geographic data, detailed in the setup and configuration sections.

Answer : B

In IBM QRadar SIEM V7.5, to deobfuscate data, an administrator requires two critical components:

Private Key: This key is used to decrypt the data that was originally obfuscated. The private key must match the public key used during the obfuscation process.

Password for the Private Key: This password is necessary to unlock the private key, allowing the decryption process to proceed.

The process involves using the private key in conjunction with its password to reverse the obfuscation, ensuring that the data is securely accessed only by authorized personnel.

Reference The requirement for the private key and its password for deobfuscating data is detailed in the IBM QRadar SIEM administration and security guides, ensuring that the process adheres to best practices for data security.

Answer : C

In IBM QRadar SIEM V7.5, Anomaly Detection Engine rules that test events or flows for volume changes occurring in regular patterns are known as Anomaly Rules. Here's how they function:

Detection: Anomaly rules are designed to identify deviations from normal behavior by analyzing patterns in the data.

Volume Changes: These rules specifically look for unusual increases or decreases in event or flow volumes that might indicate potential security incidents.

Regular Patterns: By understanding regular patterns in network traffic and event logs, anomaly rules can highlight significant outliers that warrant further investigation.

Reference The functionality and configuration of anomaly rules are covered extensively in the IBM QRadar SIEM administration guide, providing administrators with the tools to effectively detect and respond to abnormal network activities.

Answer : B

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.

Reference The 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.

Answer : A

To get a list of installed applications and their App-ID values in IBM QRadar SIEM, the administrator can run the following command:

Command: /opt/qradar/support/deployment_info.sh

Function: This command outputs detailed information about the current deployment, including a list of all installed applications and their associated App-ID values.

Usage: The administrator executes this command in the terminal, and the information is displayed on the screen.

Reference IBM QRadar SIEM V7.5 administration guides include this command as a standard tool for retrieving deployment information, including details about installed applications and their IDs.

Answer : A, C

The QRadar Threat Intelligence app uses open standards to integrate and utilize threat intelligence feeds effectively. The two key standards used are:

TAXII (Trusted Automated eXchange of Indicator Information): This is an application layer protocol used for exchanging cyber threat intelligence over HTTPS. It enables the sharing of threat information across different systems and organizations.

STIX (Structured Threat Information eXpression): This is a standardized language used for representing structured cyber threat information. STIX enables the consistent and machine-readable representation of threat data, facilitating the integration and analysis of threat intelligence.

These standards ensure that threat intelligence data is formatted and exchanged in a consistent and interoperable manner, enhancing the overall effectiveness of the threat intelligence processes in QRadar.

Reference The IBM QRadar SIEM documentation and threat intelligence app configuration guides describe the use of TAXII and STIX for integrating threat intelligence feeds.
