During a forensic investigation into a suspected cyberattack, the investigator checks network logs that were collected during the period of the incident. The investigator ' s objective is to examine these logs to determine the exact sequence of events that took place, identify the source of the attack, and understand the nature of the incident. This analysis helps in uncovering what occurred, how it happened, and who was responsible for it.
Which of the following techniques is the investigator using in this case?
In a corporate setting, a Security Operations Center (SOC) is responsible for monitoring and protecting the organization ' s digital assets.

Mia, a network administrator, is reviewing the logs of a Cisco router after noticing some performance degradation in her network. While examining the logs, she encounters a particular message that states: “The system was not able to process the packet because there was not enough room for all of the desired IP header options.” Mia needs to identify which mnemonic in the Cisco IOS logs corresponds to this specific issue. Which of the following log mnemonics should Mia look for to find this message?
Taylor, a forensic expert, has been assigned to investigate a cyber-attack on an organizational host server. The server has been compromised, and during the investigation, Taylor is tasked with analyzing network traffic to identify the attack ' s point of entry. Using Wireshark, Taylor inspects a packet capture file and notices an unusual pattern of repeated login failure attempts over the FTP protocol. Based on these failed attempts, Taylor suspects a brute-force attack targeting the FTP service. Taylor ' s next step is to confirm whether the attacker was able to successfully log into the FTP server after these failures. To verify the success of the attack, Taylor needs to identify the specific response code from the FTP server that would indicate a successful login. Which of the following Wireshark filters will help Taylor confirm successful FTP login attempts?
