Content-based signature analysis is the attack signature analysis technique employed by Finley in this scenario. Content-based signature analysis is a technique that captures and analyzes a single network packet to determine whether the signature included malicious patterns. Content-based signature analysis can be used to detect known attacks, such as buffer overflows, SQL injections, or cross-site scripting2.

Statistics is the Wireshark menu selected by Zayn in this scenario. Statistics is a Wireshark menu that provides a summary of captured packets, IO graphs, and flow graphs. Statistics can be used to analyze various aspects of network traffic, such as protocols, endpoints, conversations, or packet lengths3.

Success audit is the type of event that Brielle identified in the above scenario. Success audit is a type of event that records successful attempts to access a network device or resource. Success audit can be used to monitor authorized activities on a network, but it can also indicate unauthorized activities by malicious actors who have compromised credentials or bypassed security controls4.

bob1@sam is the file's content as the answer. To find the machine with SSH service enabled, one can use a network scanning tool such as Nmap to scan the network for port 22, which is the default port for SSH. For example, the command nmap -p 22 192.168.0.0/24 will scan the network range 192.168.0.0/24 for port 22 and display the results2. To initiate an SSH connection to the machine, one can use a command-line tool such as ssh or an SSH client such as PuTTY to connect to the machine using the credentials sam/admin@123. For example, the command ssh sam@192.168.0.10 will connect to the machine with IP address 192.168.0.10 using the username sam and prompt for the password admin@1233. To find the file flag.txt in the machine, one can use a file searching tool such as find or locate to search for the file name in the machine's file system. For example, the command find / -name flag.txt will search for the file flag.txt from the root directory (/) and display its location4. To enter the file's content as the answer, one can use a file viewing tool such as cat or less to display the content of the file flag.txt. For example, the command cat /home/sam/flag.txt will display the content of the file flag.txt located in /home/sam/ directory5.

Eradication is the IH&R step performed by Fernando in this scenario. Eradication is a step in IH&R that involves eliminating the root cause of the incident and closing all attack vectors to prevent similar incidents in future. Eradication can include applying patches, installing security mechanisms, removing malware, restoring backups, or reformatting systems.

Incident impact assessment is the post-incident activity performed by Cairo in this scenario. Incident impact assessment is a post-incident activity that involves determining all types of losses caused by the incident by identifying and evaluating all affected devices, networks, applications, and software.

Incident impact assessment can include measuring financial losses, reputational damages, operational disruptions, legal liabilities, or regulatory penalties1. Reference: Incident Impact Assessment

Cookies can contain information such as user preferences, login details, browsing history, or tracking data.

Cookies can be used to extract and analyze computer-based evidence to retrieve information related to websites accessed from the victim machine2. Reference: Cookies

A cloud auditor is a role played by Walker in the above scenario. A cloud auditor is a third party who examines controls of cloud computing service providers. Cloud auditor performs an audit to verify compliance with the standards and expressed his opinion through a report89. A cloud provider is an entity that provides cloud services, such as infrastructure, platform, or software, to cloud consumers10. A cloud carrier is an entity that provides connectivity and transport of cloud services between cloud providers and cloud consumers10. A cloud consumer is an entity that uses cloud services for its own purposes or on behalf of another entity
