In the QRadar GUI. you notice that no new offenses were generated today. A review of the notifications shows:

MPC: Unable to create new offense. The maximum number of active offenses has been reached.

What is the default value of the maximum number?

  1. 3500
  2. 1500
  3. 5000
  4. 2500

Answer(s): D

Explanation:

In IBM QRadar SIEM V7.5, the default value for the maximum number of active offenses is set to 2500. This limit is in place to manage system performance and ensure efficient processing of security incidents. Here's the detailed information:

Default Setting: The default setting for the maximum number of active offenses is 2500.

Impact: If this limit is reached, QRadar will not generate new offenses until some of the existing offenses are closed or archived.

Configuration: Administrators can adjust this setting based on their organizational needs, but the default value is 2500.

Reference
This information is detailed in the QRadar SIEM configuration and tuning guides, which specify default settings and provide instructions for modifying the maximum number of active offenses if necessary.



What Iwo things are required for an administrator to deobfuscate data in QRadar?

  1. Public key and the password for the key that is used to obfuscate data
  2. Private key and the password for the key that is used to obfuscate data
  3. Private key and public key that is used to obfuscate data
  4. Public key and the password for the private key that is used to obfuscate data

Answer(s): B

Explanation:

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.



Which two (2) pieces of information from the MaxMind account must be included in QRadar for geographic data updates?

  1. Account/User ID
  2. API key
  3. License Key
  4. MaxMind username
  5. API password

Answer(s): B,C

Explanation:

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.



To detect outliers, which Anomaly Detection Engine rule tests events or flows for volume changes that occur in regular patterns?

  1. Behavioral rules
  2. Threshold rules
  3. Anomaly rules
  4. Building block rules

Answer(s): C

Explanation:

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.
