The Uniform Resource Identifier (URI) is used to identify specific resources on the internet, including files. In the context of HTTP GET requests, the URI specifies the path to the file being requested.

Defense-in-depth is a security strategy where multiple layers of defense are placed throughout an information technology (IT) system. It addresses physical, technical, and administrative controls to provide redundancy and ensure that if one layer fails, others will be in place to thwart an attack. References: Cisco Tech Roles - CyberOps Engineer

Delivery: This step involves transmitting the weapon to the target.

Weaponization: In this step, the intruder creates a malware weapon like a virus, worm or such in order to exploit the vulnerabilities of the target. Depending on the target and the purpose of the attacker, this malware can exploit new, undetected vulnerabilities (also known as the zero-day exploits) or it can focus on a combination of different vulnerabilities.

Reconnaissance: In this step, the attacker / intruder chooses their target. Then they conduct an in-depth research on this target to identify its vulnerabilities that can be exploited.

Decision making is a principle that guides an analyst to gather information relevant to a security incident to determine the appropriate course of action. Decision making involves identifying the problem, defining the criteria, analyzing the alternatives, and choosing the best solution. Decision making helps an analyst to respond to an incident effectively and efficiently, while minimizing the impact and risk to the organization. References: https://learningnetworkstore.cisco.com/on-demand-e-learning/understanding-cisco-cybersecurity-operations-fundamentals-cbrops-v1.0/CSCU-LP-CBROPS-V1-028093.html (Module 3: Security Monitoring, Lesson 3.1: Security Operations Center)

The exhibit shows a pcap file capturing multiple TCP SYN packets directed at the same destination IP address.

High volume of SYN packets with very little variance in time: This pattern is indicative of a SYN flood attack, a type of Denial of Service (DoS) attack where numerous SYN requests are sent to overwhelm the target system.

SYN packets acknowledged from several source IP addresses: This can be indicative of a Distributed Denial of Service (DDoS) attack where multiple compromised hosts (botnet) are used to generate traffic.

These characteristics suggest that the network is under a SYN flood or DDoS attack, aiming to exhaust the target's resources and disrupt service availability.

 The PCAP file in the exhibit shows a Transmission Control Protocol (TCP) communication between two IP addresses. In the data section of the packet capture, “pdy/3.1… http/1” is visible, indicating that HTTP (Hypertext Transfer Protocol) is being used as the application protocol for this communication.

A dictionary attack is a method used to break into a password-protected computer or server by systematically entering every word in a dictionary as a password. In the context of an authentication system that uses only 4-digit numeric passwords, a dictionary attack would involve trying all possible combinations of 4-digit numbers until the correct one is found.

When a company workstation is compromised, the stakeholders that must be involved are the ones who are responsible for the security incident response process. According to the table, these are Employee 4 (Security Operation Center Analyst), Employee 6 (Head of Network and Security Infrastructure Services), and Employee 7 (Technical Director). The other employees have different roles that are not directly related to the incident response process, such as accounting, financial management, or system administration. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) v1.0, Module 1: Security Concepts, Lesson 1.4: Security Monitoring, Topic 1.4.1: Security Operations Center

 The event described falls under the ‘action on objectives’ category of the Cyber Kill Chain. This stage occurs after the attacker has established a foothold within the network and begins to execute their intended actions, such as data exfiltration. References: The Cyber Kill Chain framework outlines the stages of a cyberattack, with ‘action on objectives’ being the final step where attackers achieve their primary goal, such as data theft
