According to the National Institute of Standards and Technology (NIST), which is a primary source for cloud computing standards and guidelines, the five main actors in cloud computing are Consumer, Provider, Carrier, Auditor, and Broker. These roles are defined as follows:

Consumer: The person or organization that uses cloud computing services.

Provider: The entity that provides the cloud services to consumers.

Carrier: The organization that offers connectivity and transport services to cloud providers and consumers.

Auditor: An independent party that assesses and verifies the cloud services, security controls, and operations.

Broker: An entity that manages the use, performance, and delivery of cloud services, and negotiates relationships between cloud providers and consumers.

These actors play critical roles in the ecosystem of cloud computing, ensuring the services are delivered and used securely, efficiently, and effectively.

In the scenario where Dolphin Investment needs to implement a ticketing system for employees like Jacob to report IT-related issues, ManageEngine ServiceDesk Plus is the most suitable option among the choices provided. ManageEngine ServiceDesk Plus is a comprehensive IT help desk software that facilitates issue tracking, incident management, and efficient resolution of IT-related problems and requests. It enables users to submit tickets through various channels, including email, web portal, phone, or chat, and allows IT support teams to manage these tickets through a centralized platform. This system is designed to streamline the process of reporting, tracking, and resolving IT issues and incidents, making it an ideal solution for organizations looking to establish a formalized incident reporting and resolution process. Other options like IBM X-Force Exchange, ThreatConnect, and MISP focus more on threat intelligence sharing and security incident analysis rather than functioning as an IT help desk or ticketing system.

In the risk assessment process, "System characterization" is the initial step where the scope of the assessment is defined. This involves identifying and documenting the boundaries of the IT systems under review, the resources (hardware, software, data, and personnel) that constitute these systems, and any relevant information about their operation and environment. This foundational step is essential for understanding what needs to be protected and forms the basis for subsequent analysis, including identifying vulnerabilities, assessing potential threats, and determining the impact of risks to the organization.

Explanation (aligned to IH&R best practice):

Insider threats are most effectively reduced by combining least privilege with continuous detection of abnormal behavior. Regular access reviews ensure that users only retain permissions needed for their roles (reducing “privilege creep”), while behavior analytics help detect misuse that still occurs within “legitimate” access. Password rotation (A) is largely hygiene and does not prevent a determined insider who already has authorized access; frequent forced changes can also push unsafe behaviors (writing passwords down, predictable patterns). A strict hierarchy (B) is not practical and does not map to “need-to-know”—seniority is not the right control boundary, job function is. Biometrics (C) strengthens authentication, but the scenario’s problem is not identity uncertainty; it is misuse by a valid insider. The most effective approach is therefore governance + monitoring: (1) define data access baselines, (2) review permissions routinely, (3) alert on suspicious actions such as unusual repository cloning, bulk downloads, access outside normal hours, or atypical branches, and (4) investigate quickly with HR/legal processes. These measures directly address motive-driven misuse by enabling early detection and limiting the blast radius. This aligns with the broader incident handling emphasis on identifying affected systems/data, understanding scope, and improving controls post-incident to prevent recurrence.

A Trojan attack involves a type of malicious code or software that appears legitimate but can take control of your computer. Trojans often disguise themselves as legitimate software or are hidden within legitimate software that has been tampered with. They differ from viruses and worms because they do not replicate. However, once activated, Trojans can enable cyber-criminals to spy on you, steal your sensitive data, and gain backdoor access to your system. This can include unauthorized actions such as deleting files, monitoring user activities, or installing additional malicious software.

During the incident handling and response (IH&R) process, the stage of "Evidence gathering and forensics analysis" involves the collection of evidence, forensic analysis, and detailed investigation to uncover the root cause of the incident. This stage is crucial for understanding how the incident occurred, identifying the threat actors involved, the methods they used (threat vectors), and the extent of the impact. By analyzing evidence, incident responders can reconstruct the sequence of events, identify the vulnerabilities exploited, and determine the scope of the incident. This information is vital for resolving the incident effectively and taking steps to prevent future occurrences.

Process memory, or volatile memory (RAM), is digital evidence that requires a constant power supply to retain data and is deleted or lost when the power supply is interrupted. It contains information about the system's ongoing processes and operations. This type of evidence can be crucial for forensic investigations as it may hold information about user actions, system events, and the state of applications and services at the time of an incident. Unlike swap files, event logs, and slack space, which can retain information without a constant power supply, process memory is inherently volatile and its contents are lost when a device is powered off or restarts.

Incident response orchestration refers to the process and technologies used to coordinate and streamline the response to security incidents. This approach ensures that incident response teams have clear procedures and workflows to follow, enabling them to act swiftly and effectively when dealing with security incidents. By orchestrating the response, organizations can minimize the impact of incidents, ensure consistent and thorough investigation and remediation activities, and improve their overall security posture. Incident response orchestration involves integrating various security tools, automating response actions where possible, and providing a centralized platform for managing incidents.

The indicators described align closely with a Distributed Denial-of-Service (DDoS) attack, a major topic in the ECIH Network Security Incidents module. DDoS attacks overwhelm network and system resources using traffic from multiple sources, often distributed across geographic regions.

Excessive ARP traffic, NAT table exhaustion, elevated CPU usage on routers, and simultaneous connection attempts are classic symptoms of volumetric and protocol-based DDoS attacks. The involvement of multiple geolocations, as reported by the ISP, further confirms the distributed nature of the attack.

Option B is correct because no single-host misconfiguration or reconnaissance activity would generate this volume and diversity of traffic. Option A would cause IP conflicts, not global traffic floods. Option C focuses on stealthy outbound activity, not inbound saturation. Option D is low-volume and targeted.

ECIH emphasizes early identification of DDoS conditions to enable rapid containment using rate limiting, blackholing, or ISP coordination. Recognizing these indicators is critical to protecting service availability.

An inappropriate usage incident involves misuse of the organization's resources or violations of its acceptable use policies. Sam's actions, where he sends emails to third-party organizations with a spoofed email address of his employer, constitute misuse of the organization's email system and misrepresentation of the organization. This behavior can harm the organization's reputation, violate policy, and potentially lead to legal consequences. Inappropriate usage incidents can range from unauthorized use of systems for personal gain to the dissemination of unapproved content.
