The exhibit shows a high rate of SYN packets being sent from multiple sources towards a single destination IP. This is indicative of a SYN flood attack, where the attacker sends a succession of SYN requests to a target’s system in an attempt to consume enough server resources to make the system unresponsive to legitimate traffic. References := Cisco Cybersecurity Operations Fundamentals - Module 4: Network Intrusion Analysis

The difference between tampered and untampered disk images is:

Tampered Images: These are disk images that have been altered or modified in some way after their initial creation. The stored hash and the computed hash will not match if the image has been tampered with.

Untampered Images: These are disk images that have not been altered since their creation. They are considered authentic and reliable for forensic investigations. The stored hash and the computed hash will match, confirming that the image has remained unchanged.

Therefore, the correct answer is: D. Untampered images are used for forensic investigations.

 Indicators of attack (IoAs) are signs that an attack may be in progress or imminent. Malware reinfection within a few minutes of removal (D) is a strong IoA because it suggests that the attacker has a persistent mechanism to redeploy malware, indicating an active compromise of the system.

The Cuckoo report indicates that the file is a PE32 executable for MS Windows, which is typically an executable file format. The presence of the watermark “CHINESEDUMPS” and the detection ratio from VirusTotal suggest that the file is recognized by multiple antivirus engines as potentially harmful. This aligns with option A, suggesting that the file, named Win32.polip.a.exe, should be considered malicious and flagged accordingly.

The information provided is based on standard practices for analyzing potentially malicious files using tools like Cuckoo and services like VirusTotal, which are commonly referenced in cybersecurity documentation, including Cisco’s cybersecurity training materials.

 In the context of a cybersecurity breach, attribution involves identifying the responsible party. Since the external USB device was not found, the focus shifts to the actions performed by the receptionist. Analyzing these actions can provide insights into how the breach occurred and may help in attributing the incident to the threat actor

The exhibit shows a network diagram with a switch, a router, and two hosts. The switch has a MAC address table that maps the MAC addresses of the connected devices to the corresponding ports. A MAC flooding attack is a type of attack that aims to overload the switch’s MAC address table by sending a large number of frames with spoofed source MAC addresses. This causes the switch to enter a fail-open mode, where it broadcasts all incoming frames to all ports, effectively turning it into a hub. This allows the attacker tosniff the traffic between the hosts and the router, or launch other attacks such as ARP spoofing or man-in-the-middle

The main difference between inline traffic interrogation (TAPS) and traffic mirroring (SPAN) lies in how they handle network traffic for analysis purposes. TAPS, or Test Access Points, are hardware devices that create a copy of the traffic between two network points without altering the data. This means TAPS can transmit both send and receive data streams simultaneously on separate dedicated channels, ensuring all data, including physical layer errors, is received by the monitoring or security device in real-time. On the other hand, SPAN, or Switch Port Analyzer, is a feature that duplicates network packets seen on one port to another port for analysis. However, SPAN ports can filter out physical layer errors, which may limit the types of analyses that can be performed as some errors will not be represented in the mirrored traffic.

The distinction between TAPS and SPAN is covered in the Cisco CyberOps Associate CBROPS 200-201 course, which provides foundational knowledge for network monitoring and security analysis1. Additionally, industry resources such as Garland Technology’s comparison of TAPS and SPAN highlight the differences in performance and integrity of the traffic being analyzed
