Security QRadar, Associate Analyst Flashcards

When tuning a noisy QRadar rule that is generating excessive false positives, which approach is most appropriate?

Answer: Add exception conditions (such as trusted IP ranges or known safe users) to the rule's tests to filter benign activity

Adding exception conditions or building block exclusions narrows a rule's scope without removing its ability to detect genuine threats.

Which QRadar component would an analyst access to review the current health, status, and license consumption of a QRadar deployment?

Answer: System Administration (Admin tab)

The Admin tab in QRadar provides access to system settings, component health, license metrics (EPS/FPS), and administrative configuration.

In QRadar, what is the difference between a 'Reference Set' and a 'Reference Map'?

Answer: A Reference Set stores single values in a list; a Reference Map stores key-value pairs

Reference Sets are flat single-value lists, while Reference Maps associate a key with a single value, enabling lookups like IP-to-username mappings.

An analyst observes that a QRadar offense has been 'dormant' for 5 days. What does a dormant offense status indicate?

Answer: No new events matching the offense's rules have occurred within the configured dormancy period

QRadar marks an offense dormant when no new correlated events have been added to it within the system's configured dormancy interval.

Which IBM QRadar certification exam is aligned with the 'Associate Analyst' role validation?

Answer: C1000-018 (IBM QRadar SIEM V7.3.2 Associate Analyst)

The C1000-018 exam validates foundational QRadar SIEM analyst skills including log source management, offense investigation, and rule creation.

What action should an analyst take in QRadar when an offense is confirmed as a true positive security incident requiring remediation?

Answer: Assign the offense to themselves or a team, document findings in the offense notes, and follow the incident response process

Best practice for confirmed incidents is to assign ownership, document investigation steps in notes, and coordinate remediation through the defined IR process.

A QRadar analyst wants to detect brute-force login attempts where a single IP makes more than 20 failed authentications within 5 minutes. Which rule element is essential for this?

Answer: A threshold test that counts event occurrences within a defined time window grouped by source IP

Threshold tests count matching events over a configurable time window and can be grouped by fields like source IP to detect volumetric attack patterns.
