Packet number 2318 is the one that contains a file that is extractable within Wireshark. This can be determined by the information provided in the packet details, which typically includes an HTTP GET request indicating the retrieval of a file, such as an image or document1.

False-positive alerts are alerts that are triggered by benign or normal network traffic and are mistakenly identified as malicious. False positives can have a negative impact on business as they may consume the resources and time of the security team that need to analyze and verify them. True-positive alerts are alerts that correctly identify malicious traffic or activity and require proper incident response procedures. True positives can help the security team to quickly detect and mitigate threats and minimize the damage to the organization.

The exhibit shows a UNIX command being used to filter data from an Apache access log file. The use of
"cat" to display the content of the log file, "grep" to filter specific IP addresses, and "cut" to organize the output are all indicative of operations performed on a UNIX-based system. Additionally, the structure of the logs (GET requests) aligns with the format typically found in Apache server logs.

Full packet capture provides the complete recording of all the packets that are transmitted over the network.
This data is essential for in-depth analysis during an investigation, as it allows investigators to reconstruct the session, observe the content of the traffic, and determine if data exfiltration has occurred.
