A security operations center analyst is using the command line to display specific traffic. The analyst uses the following command: `$ tshark -r file.pcap -Y 'http or udp'`. Which of the following will the command line display?
Unencrypted web requests and DNS traffic
The provided command instructs tshark to read the file file.pcap and display traffic matching the filter 'http or udp.' This filter will capture unencrypted web (http) requests and UDP traffic, which commonly includes DNS packets. Therefore, the displayed output will consist of unencrypted web requests and DNS traffic.
This option is incorrect because the filter specified in the command line ('http or udp') does not target encrypted traffic. As a result, only unencrypted web requests will be captured along with DNS traffic.
This choice is incorrect as the filter 'http or udp' explicitly includes web (http) traffic and UDP packets. Therefore, the displayed output will contain unencrypted web requests and DNS traffic, not neither of them.
This option is incorrect because the command provided does not include a filter for encrypted traffic. The 'http or udp' filter specifically targets unencrypted web (http) traffic and UDP packets, excluding encrypted traffic. Thus, the displayed output will only include unencrypted web requests and DNS traffic.
By utilizing the specified tshark command with the filter 'http or udp,' the security operations center analyst will view unencrypted web requests and DNS traffic from the file.pcap. This command helps in isolating and analyzing specific types of network traffic, aiding in security monitoring and incident response efforts.
