What is the primary purpose of rwipview in SiLK?

To filter flow records based on criteria

To visualize network traffic patterns and identify communication between IP addresses

To count flows over time intervals

To generate top-N statistics from flow records

What is the purpose of the rwgroup tool in SiLK?

To aggregate flow records by specified fields, such as source IP or destination port

To count flows and packets over time intervals

To convert packet capture files to flow records

To generate top-N statistics from flow records

An incident response team is investigating a potential data breach. They have SiLK flow data showing large outbound transfers, and they also have Zeek logs from the same period. The team needs to correlate the flow data with specific application-layer details, such as the URLs accessed. Which approach best combines these tools?

Use rwfilter to identify the large flows, then cross-reference the timestamps and IPs with Zeek's http.log to find the URLs.

Use rwstats to generate top-N statistics and ignore Zeek logs.

Use tcpdump to re-capture the traffic and analyze it with Wireshark.

Use Argus to generate new flow data and compare it with SiLK.
