This paper examines insider threats within cloud computing networks, drawing on current literature to analyze the technical, organizational, and ethical dimensions of cloud security. It explores how the architecture of cloud systems — including abstracted infrastructure and remote access — creates unique vulnerabilities for both business organizations and their cloud service providers. The paper reviews available security countermeasures such as encryption, data partitioning, and human resources controls, and considers a real-world case study from the 2011 Thailand floods. It also addresses the financial and legal costs associated with cloud security transitions, arguing that expanded research on insider threats and cost-feasibility is urgently needed as cloud adoption accelerates.
This paper demonstrates effective literature synthesis: rather than summarizing each source individually, the author weaves multiple citations together within thematic paragraphs to build a cumulative argument. For example, Qaisar & Khawaja, Reddy & Reddy, and Durkee are cited together to show how different dimensions of the same problem reinforce one another, strengthening the claim beyond what any single source could support.
The paper opens by framing a research gap, then proceeds through specific threat types, architectural vulnerabilities, available countermeasures, a real-world case study, and broader ethical/financial concerns before concluding with a call for expanded research. This funnel-to-gap structure — broad context narrowing to an underexplored specific problem — is a common and effective approach for literature-based academic writing at the undergraduate level.
The diversity of threats that cloud networks face, and the complexities involved in effectively countering these threats in a manner that allows companies to truly take advantage of such technologies without enormous security and control expenditures, have made these networks and their security issues the subject of abundant research and literature in recent years. Numerous perspectives have been brought to bear on these problems and the means by which they can be addressed — from directly practical examinations of a technical nature, to larger-scale theoretical understandings of the practicalities of cloud computing in the real world, to a consideration of certain ethical concerns that exist alongside all of these practicalities. While the issue of cost feasibility as a direct measurement of risks and solutions presented by insider threats inherent to cloud computing networks has not been specifically addressed in the research, current literature does provide a comprehensive foundation upon which to build such an investigation.
Addressing insider threats to cloud computing networks is itself problematic, as there are many modes of external attack or unauthorized access that could be utilized by insiders perhaps more easily than by wholly external forces (Qaisar & Khawaja, 2012). Whether or not these would truly be considered insider threats is a matter of semantics, but the fact is that an insider would be in a better position to launch a number of attacks, including a "man in the middle" attack — intercepting communication between two parties that was meant to be private and encrypted — and "network sniffing," which involves gaining unauthorized access to a network via password hacking or retrieval (Qaisar & Khawaja, 2012).
These risks are not even specific to cloud networks, as they exist for traditional networks as well. However, greater vulnerabilities exist in cloud networks due to the remote access that is an inherent part of even authorized use of such networks (Qaisar & Khawaja, 2012; Reddy & Reddy, 2011). This limits the degree to which current network security measures can be implemented against potential attacks on a cloud network, both internally and externally, and can make it extraordinarily more difficult to track where attacks are or might be coming from (Reddy & Reddy, 2011). Every element of a cloud computing network that makes it more vulnerable to external attacks also makes it more vulnerable to internal attacks, and makes it easier for internal attackers to hide their tracks and to gain broader access (Reddy & Reddy, 2011).
The many problems specific to cloud computing and to insider threats only add to the complexity and difficulty of dealing with these security problems in a manner that is effective and efficient for medium- to large-scale enterprises. Perhaps most importantly, the very architecture of a cloud computing network removes actual hardware and software control from the organization that needs to maintain network security as a direct means of protecting its interests. This "abstracted infrastructure" typically means that even the type of hardware and software being used to protect their data is unknown to the organizations and individuals that utilize cloud computing networks (Durkee, 2010).
This level of ignorance can make it much more difficult to develop and implement effective security measures on the user end of the network, and also creates an inherent dependence on an outside organization to maintain strict security protocols in its own processes and with its own personnel. Insider threats are therefore not faced solely within the business organization, but also within the cloud computing service provider's organization (Durkee, 2010; Reddy & Reddy, 2011). Combined with the fact that all substantially sized cloud computing service providers have different contractual obligations and perhaps different methodologies for every client organization whose data and processes they handle, the threat of accidental security breaches or lapses, accidental data loss or process interruption, and a host of other malicious and accidental security threats emerge as serious problems in the nature of insider threats in such networks (Reddy & Reddy, 2011).
Cloud computing is unquestionably the way of the future, and as more companies reduce their own expenses and increase efficiency by making such transitions, those that remain behind will find themselves unable to compete in a few years. It is for this reason that so much research has been generated in recent years when it comes to cloud computing generally and security in cloud computing specifically. At the same time, not enough research has been conducted when it comes to specifically addressing insider threats and the cost of controlling security threats in cloud computing, and the need for businesses to transition to the cloud makes the urgency of expanding current literature in this area quite pressing.
