C1000-156 Exam Dumps : IBM Security QRadar SIEM V7.5 Administration

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.

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

The primary method used by IBM QRadar SIEM V7.5 to alert users to problems is through System Notifications. Here’s how it works:

System Notifications: These are alerts generated by QRadar to inform users of various issues, such as system performance problems, license issues, or security incidents.

Visibility: Notifications are prominently displayed in the QRadar GUI, ensuring that administrators and users can quickly identify and respond to any problems.

Customization: Users can configure notification settings to receive alerts for specific types of issues, ensuring they stay informed about critical aspects of the system’s health and performance.

ReferencesIBM QRadar SIEM documentation outlines the use of System Notifications as theprimary method for alerting users to issues, detailing how to configure and manage these alerts.

In IBM QRadar, the magnitude score of an offense is influenced by several parameters, one of which is credibility. Here’s a detailed explanation:

Magnitude Score: The magnitude score represents the severity and importance of an offense in QRadar. It is a composite score that helps prioritize incidents for investigation.

Credibility Parameter: Credibility assesses the reliability of the event source and the likelihood that the event represents a real threat. Higher credibility indicates that the source is reliable and the threat is more likely to be legitimate.

Contribution to Magnitude: The credibility parameter directly influences the magnitude score by weighting the offense higher if the credibility of the event ishigh. This ensures that more reliable and potentially more severe incidents are prioritized.

Credibility is one of the key factors used by QRadar to assess and prioritize security incidents, ensuring effective incident management.
