What is network activity in QRadar?

In IBM® QRadar® SIEM you can investigate the communication sessions between two hosts. If the content capture option is enabled, the Network Activity tab displays information about how network traffic is communicated and what was communicated.

How does QRadar extract user information from network flows?

QRadar uses device support modules (DSMs) to understand and categorize events from log sources. Log sources that generate identity contribute the building asset profiles in QRadar. To determine which log sources generate identity, you can view the appendix of the DSM Configuration Guide.

What is QRadar network insights?

QRadar Network Insights provides in-depth analysis of both network metadata and application content to detect suspicious activity that is hidden among normal traffic and extract content to provide QRadar with visibility into network threat activity.

Which QRadar module collects configuration of network devices?

QRadar Risk Manager collects network infrastructure configuration, and provides a map of your network topology.

What technologies does the QFlow collector use to capture raw network packets?

The QRadar QFlow Collector uses a dedicated Napatech monitoring card to copy incoming packets from one port on the card to a second port that connects to a IBM QRadar Packet Capture appliance.

How do you analyze QRadar logs?

On the Play logs in QRadar screen, click the arrow next to the log file that you want to play. Analyze the events that were generated by the log file. Click the Log Activity tab. To select a single event to review, click the Pause icon to pause streaming, and then double-click the event.

What is QRadar QFlow?

The component in QRadar that collects and ‘creates’ flow information is known as “qflow”. QFlow can process flows from multiple sources. Sources that include packet data by connecting a span/monitor port, or network tap, to a Flow collector are referred to as “internal sources”.

What is QRadar and Splunk?

The QRadar® App for Splunk Data Forwarding enables communication so that you can forward raw data from the Splunk Enterprise or the Splunk Universal Forwarder to QRadar for analysis. QRadar parses the data from Splunk the same way that it parses data from other sources and displays the data in the Log Activity tab.

QRadar Network Activity is the second important tab in QRadar interface. Each flow is a record of the communication between two machines, minute by minute in the network where resides QRadar. This value of one minute is constant and its change is not possible. Flows deliver information of existing network traffic.

How to join asymmetric flows in QRadar?

You can configure a QRadar Flow Processor to join Asymmetric Flows records running in the same session. In a QRadar deployment, we can use t his feature, where a one Flow Processor receives flow records from two sources and where first one inbound flow and the other is outbound records.

What are unidirectional flows in QRadar?

Sometimes in networks, we can configure traffic to use different paths for incoming and outgoing traffic. QRadar can join the traffic into a single flow. We can configure a Flow Source to accept unidirectional flows also known as Asymmetric Flows. These are flows, where no sources or destination packet
