C1000-162 Exam Dumps and Practice Questions

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.

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 areDNS LookupandWHOIS Lookup1.These options provide additional information about the IP address, such as its domain name (DNS Lookup) and registration information (WHOIS Lookup)1.

In IBM Security QRadar SIEM, generating a report using the QRadar Report Wizard requires a 'Saved Search' and a 'Layout.' A Saved Search is a predefined search criterion that users save in QRadar to reuse for various reporting or analysis purposes. It acts as the data source for the report, defining what data will be included. The Layout component refers to the structure and presentation of the report, including how the data from the Saved Search is organized and displayed. It encompasses the formatting, charts, tables, and other visual elements that make up the final report. Together, these components ensure that reports are not only informative but also well-organized and readable, catering to the specific informational needs and preferences of the users or stakeholders.

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.

QRadar will mark an Event offense as dormant if no new events or flows occur within 30 minutes. However, if QRadar did not process any events within 4 hours, this also triggers the offense to become dormant. Once dormant, the offense remains in this state for 5 days unless new events or flows are added.
