Impact of LAN/WAN on Database Security in the Cloud Computing Environment

Abstract


 

Cloud computing has been gaining momentum as a business platform due to its practically unlimited Internet-powered infrastructure as well as its various advantages over proprietary applications. However, while subscriptions to cloud-based services results in cost efficiency among users, the open nature of the cloud computing environment exposes it to security threats. The attractiveness of the cloud computing environment lies in the simplicity with which organizations can enhance their information system and almost effortlessly adapt to it. The very simplicity, which entices organizations to the clouds, nevertheless renders it vulnerable to unscrupulous entities that prey on corporate and confidential client data to serve their selfish motives through unauthorized access.

As cloud applications and services operate in a virtual environment, the open nature of the technology empowers businesses through data and device independence, sharing capability, scalability, and agility. The same virtual environment, however, makes database security a primary concern as the openness of its enhanced virtual interfaces facilitates easy access and/or transfer of information across computer channels. This renders cloud computing a potential target for security attack vectors in the form of denial of service (DoS), cloud malware injection, authentication, and man-in-the-middle cryptographic attacks, among others. The mere fact that information is stored in databases makes them critical areas for data security. The local area network/wide area network (LAN/WAN) bridges the interconnectivity between organizational users and cloud services, and this is one aspect of data security in cloud computing which can benefit from further research. Therefore, this study will attempt to assess the impact of LAN/WAN on database security in the cloud computing environment.

Introduction


 


            Security issues are a key concern in cloud computing in the light of new security threats which evolve.vis a vis, the rapid advances in Internet and information technology. It is thus reasonable to expect that these threats will perpetuate within creasing use of technology. New countermeasures are necessary to maintain the integrity of the information technology systems susceptible to these threats (Michael & Denolt, 2010; Sridhar, 2010). Security issues, therefore, constitute an enduring concern in cloud computing (Verma & Kaushal, 2011).

            Traditionally, data security models are aimed at protecting the perimeter of the organization. In the more recent technology environment, however, this approach is no longer sufficient. Particularly, in the case of cloud computing, potential risks are as likely to come from within the organization as from external sources. Among other critical procedures, measures to control data corruption, access, disruption and loss must be adapted to the new cloud computing paradigm. This poses a great challenge for organizations which have migrated to the clouds because whether it is in the public or private cloud, data is practically under the control of the service providers (Wang, 2012).

            Businesses that have migrated their information systems to the clouds are at the mercy of data security being offered by providers unless they opt to reinforce their data security at their own costs. Needless to say, therefore, that data security is not guaranteed fail-secured. Accordingly, cloud-enabled organizations are concerned with the security of their information, especially with regard to exposure to unauthorized parties. Moreover, attacks are changing to more sophisticated forms to gain access to specific types of data and take control of valuable corporate information. 

            Cloud computing offers a multiplicity of advantages to business organizations, ranging from cost efficiency to easier exchange of valuable data within various frameworks. Nevertheless, businesses face many challenges with their migration from traditional to open systems. As data travels through wired and/or wireless networks, data protection is essential. Data protection is especially vital to assure client confidentiality and security compliance for businesses. Being an emergent technology, cloud computing will undoubtedly benefit from research aimed at bolstering data protection and security. This alone provides a strong justification for the conduct of the proposed study.

            There are a number of external factors which may affect the proposed study. The factors include: Data location or database, otherwise data centers; network topology of the underlying environment; data segregation; external servers, especially when they are compromised; and pertinent regulations (Sangroya, Kumar, Dhok & Varma, 2010). These will be explained in the next section.

One aspect of data security in the cloud computing environment which can benefit from further research is the local area network/wide area network (LAN/WAN). According to Cleveland (2009), LAN/WAN database security is customized by cloud service providers in response to various customer needs given the level of control the organization needs or requires. However, data security offered by cloud service providers is usually not sufficient which necessitates other ways of ensuring data security of the LAN/WAN in the cloud computing database. Protection and proper reporting is seen as a positive framework on which to formulate software to counteract threats. Furthermore, increased awareness of Trojan and hacker attacks, as well as other vector attacks, is crucial in being able to build a standard database server security.

Ultimately, being prepared against the aforementioned security attacks is viewed to be important in database security as LAN/WAN systems are now integral to industry business practices. LAN/WAN systems are vital as they assure faster data exchange and efficient information storage. Furthermore, LAN/WAN networks facilitate ideal interconnectedness both in a wired and wireless framework (Mather et al., 2009).

According to Lyon, (1997) devices connected to a LAN or to the Internet by means of modern technologies that include well-known and not-so-well-known ports increase the need for secure operation . Improved WAN performance adds an extra degree of security by transporting data through distinctive well-secured pipelines. Both LAN and WAN security implementations are beneficial for both service providers and enterprises as they broaden virtual networks outside their facilities, leading these security measures to enhance higher network productivity (Cole, 2009). To facilitate strengthening of data security in the cloud- computing environment through LAN/WAN, there is a need to assess its impact in the cloud from the perspective of business organizations subscribed to cloud services and service providers.

            This proposed study will, therefore, serve as a forum for organizations and providers to contribute their experiences in securing their business data in the cloud, particularly with respect to LAN/WAN. Inputs from the study will eventually be synergized to develop a best practices approach that could lead to better infrastructure development as explained in Rittinghouse and Ransome (2009). To this end, it is hoped that organizations who have harnessed cloud computing utilities will be able to effectively monitor data exchanges, especially in terms of securing access from the back to the front- end portions of the system. This is integral to intelligent security management, and the proposed study will be instrumental in rendering a higher level of data security in the context.

Background of the Study


Hackers take advantage of open systems by striking during data transfers as more companies are entering the cloud-computing environment (Dumas, 2013).Computer security experts, therefore, cite the need to safeguard memory, CPU, storage, and program execution in order to mitigate any security attacks. LANs and WANs are at the core of cloud services as these networks serve as links between the providers and consumers of cloud-based applications and other utilities (Lin & Devine, 2010),  Accordingly, the main challenge in the LAN/WAN system is the implementation of proper distribution channels where encryption algorithms are used while data is being transferred over the Internet. A case in point would be wireless LANS using the IEEE 802.11b technology standard since encryption here can easily be broken. Once encryption is broken, the corporate network can be illegally accessed and hackers can intercept data being transmitted at will (Joshi, 2004).

Furthermore, the lack of well-defined security standardizations should be emphasized. There is a lack in transparency with respect to security measures and processes applied by cloud service providers. Cloud consumers currently have to trust their providers that the services they are subscribed to are compliant with current security standards. To illustrate, a formidable establishment renowned for its online business and one of the pioneers in cloud-based technology announced in 2010 that it is compliant with ISO 27001 and PCI DSS Level 1, which are baseline security measures for traditional computing. The problem, however, is that to date, “no agreed standard criteria for running a secure cloud infrastructure exist” (Doelitzscher, Reich, Knahl & Clarke, 2013, p. 130). The question of whether the security standards for traditional computing apply to cloud based computing has not yet been settled.

The rate in which organizations are transferring from traditional models of computing into the new software architectures is also a security alarm making it necessary to become aware of new threats and vulnerabilities. Many cite the lack of ERP and operating systems in business applications as a striking vulnerability whereby many virtual business transactions create increasing security problems (Rittinghouse & Ransome, 2009). Access control can, therefore, be enhanced to mitigate the risks of compromising the security of corporate and client information (Buyya, et al., 2011). In this regard, LANs and WANs are potential areas for tightening access control to bolster data security by virtue of their function in the cloud computing architecture.

            A number of external factors are, however, believed to influence data security in cloud computing. Data loss or data security threats cannot be assumed on just one point of failure, because data may be located at various geographically-distributed nodes in the cloud. Thus, there are multiple points where data security may be compromised in the cloud. Organizational and individual users of cloud computing services generally do not have knowledge of the underlying network topology of the cloud-based service they are subscribed into. They are, therefore, constrained by this impediment in cases where clients may want to supplement data security on their end (Sangroya, Kumar, Dhok & Varma, 2010).

            Data stored in the clouds are usually shared in the same environment as other data. The common approach of encrypting data to prevent unauthorized users from benefitting from hacked data does not present a sufficient solution for security problems pertaining to data segregation. In cases when cloud servers are compromised, shutting down servers to protect data will result in unavailability of data, which is as challenging as data loss or unauthorized data access for business organizations. Additionally, compliance to emerging cloud regulations by government bodies may also exert some influence on the data security since cloud service providers are subject to adhere to security audits (Sangroya, Kumar, Dhok & Varma, 2010).

            The development of the cloud as a business system was pioneered by Amazon.com, with multiple data centers utilized based on a utility computing basis. This trailblazing practice further enhanced their operational efficiency as an online retailer. The firm successfully maintained their database security by prioritizing protection of their LAN/WAN system(Reese, 2009). Amazon’s cloud model implemented technology to facilitate provision of more control for their clients via the LAN/WAN system. While off-premise data storage in Amazon’s data centers are subject to connectivity and latency constraints between the clients’ LAN and the data centers, security measures, particularly encryption, strengthened database protection (Hurwitz, Kuafman, Halper & Kirsch, 2012). 

            The cloud architecture has since been developed by other companies such as Google and IBM with strides in the improvement of the security systems. The current trend is to transfer company owned hardware and software assets and sharing systems on a per-service basis. This amasses huge savings for the company with the reduction of cost- upkeep expenditures on their end (Reese, 2009).

As the Internet and online retailing has boomed since the new millennium, the lack of standardization has led to the creation of a Cloud Security Alliance by eBay and ING, among others, in order to promote best practices in the industry. The alliance has since been adopted as a platform to share information and security experiences with other computer technology experts (Messmer, 2009). Forming alliances presents an opportunity for organizations to partner with cloud providers to help reduce their overall risk exposure. Accordingly, the alliance group has announced fifteen domain areas of concern that should be prioritized for organizations in order to assure database security in a LAN/WAN system. These are governance and enterprise risk, information and life-cycle management, compliance and audit, e Discovery, which  is production of electronically stored information (Buyya, Broberg & Gościński, 2011), encryption and key management, application security, identity and access management and incident response. Other technological groups such as Sun Microsystems, VMware and IBM have cited portability, interoperability and monitoring as key security issues in a LAN/WAN security database (Rittinghouse & Ransome, 2009).

            The rate at which businesses use on-demand cloud computing is noteworthy, as adoption rates have doubled annually(Buyya, Broberg & Gościński, 2011). However, businesses must be able to adapt to cloud technology without hampering their own daily operations. Security issues constitute an enduring concern in cloud computing (Verma & Kaushal, 2011).Ironically, security threats evolve in tandem with technology and  new countermeasures are necessary to maintain the integrity of the information technology systems susceptible to these threats. It is thus reasonable to expect that the threats will rise with the increasing use of technology (Michael & Denolt, 2010; Sridhar, 2010).

The main issues of database security on a LAN/WAN cloud-computing environment are the lack of standardizations, business models, and varying opinions on sources of security threats. Furthermore, the increase in the number of security providers is adding confusion for organizations as how tobest address the issues at hand. Database security is a top priority, but balancing this with the cost savings of adopting a cloud-computing environment creates a myriad of problems for users and organizations. An additional problem is the availability of experts in cloud computing technology is few as it is only an emerging technology (Gnanasundaram & Shrivastava, 012). Moreover, manycite the rate of change of an organization’s security measures are lower compared to the ability of hackers to create software programs that are aimed to steal confidential information ( Lambert, 2005; Mather, et al., 2009; Jackson, 2012) . This indicates the need for industry experts to formulate stronger alliances to counteract looming security risks in the horizon (Mather et al., 2009).

 

Problem Statement


Cloud computing is seen as an advantageous technological advancement being adopted by many industries globally. Its sharing mechanism generates faster savings and higher profit margins that are beneficial to many businesses. Meanwhile, Information sharing in a LAN/WAN security database is vulnerable to security risks under a cloud-computing environment. This is due to the use of the Internet to transfer data from front- to back-end users. It is even complicated more with the use of multiple servers storing and sending data across various computers. Therefore, before adopting cloud computing, it is imperative for organizations to consider the security system before embarking on a company-wide infrastructure shift.

The cloud computing architectural environment must be robust against security threats and physical defects in order for the company to optimize gains. This will require an understanding of the risks inherent in cloud computing by applying best practice methods and following legal compliance guidelines (Rajan, 2010). Any technology solution which enhances company operations and/or financial performance will have its own drawbacks. The attractiveness of cloud computing in terms of expanse and flexibility is countered by underlying threats to security. Companies should, therefore, weigh their options very carefully before changing to the new technology.

The age of infallible database security systems no longer exist, especially with the open nature of cloud computing environments. As such, the realization of threats is necessary in order to mitigate security risks in its adoption (Mather et al., 2009). If, indeed the advantages of migration into the cloud offset the risks to security that an organization may be exposed, such risks should nonetheless be manageable. The impenetrability of LANs and WANs from unauthorized intrusion during data transmission, and even during storage, presents a viable direction for enhanced security measures. To this end, a deeper knowledge of the impact of LANs and WANs in database security in the cloud environment offers a potent area for research.

A key motivation for the research is the opportunity to address the challenges database security face especially in assuring public confidentiality and privacy. More over, the Internet and cloud computing are invaluable tools in the business process. Optimizing the advantages of cloud computing is crucial for industries so that they can harness the power of the Internet to improve their financial performance.

The objective of this study is, therefore, to promote best practices in the industry while developing security software programs to address security risks. It is, likewise, equally important to conduct an intelligent management and resource allocation of cloud computing providers in order to build a reliable and efficient business infrastructure model that satisfies both companies and consumers in terms of cloud services and data security. Best practices, however, do not exist in a vacuum. Data security practices which one company successfully implemented on their end need to be communicated with comparable organizations to verify whether the practice is generally applicable to other companies or uniquely useful to just one organization. It is hoped that Inputs from other firms can help develop one company practice into an industry best practices network.

The expected outcome is to promote a better understanding of LAN/WAN database computing security in a cloud-computing environment to the general public. Significantly, basic security measures can be initiated for small to medium sized companies in order to protect the interests of all parties within the system of networks. The promotion of a best practices approach is to build mutually beneficial relationships with providers and users creating a strong virtual organization. This serves as a preventive method for data loss, insider threats, and organized crime using high-tech methods that will be ultimately advantageous for all users.

Cloud computing is the technology of the future. With Internet technology advancing in leaps and bounds, virtual computing in the cloud is the ultimate technology to learn more about in the next decade. A synergy of expert knowledge and crucial company experiences of cloud service providers and consumers can help elevate cloud computing into the next level where data is no longer a hindering threat, but a facilitating opportunity for corporate growth and expansion.

The SaaS or “Software as a Service” is seen to be the most vulnerable, wherein hackers can easily use this route to enter the business database and information technology systems. Experts cite that newer systems are, in fact, more susceptible than traditional computer architectures as cloud computing, in effect makes business operations seem to have fewer boundaries. The invention of other electronic gadgets such as the PDA and the laptop is also a source of security threats, especially with their ability to store customer information as high as 8GB. All of these gadgets also contain private information that lacks encryption methods. More importantly, the ability to transfer data between computers is also a source of data loss within companies, making it necessary to apply physical security measures. This includes monitoring all sources of information whether electronic, hard copy or in transit (Mather et al., 2009).

Amongst all these sources is the ability to monitor transit information in a LAN/WAN system as firewalls and intrusion detection systems serve as the current best practices in information security. The promotion of regular risk evaluations is also necessary by auditing risk threats for businesses under a cloud-computing environment. Other than data loss is data leakage, as mobile technologies make it easier for hackers and even employees to use data and transfer information. This has increased the call for the development of data loss prevention systems to be included in the LAN/WAN security of database in a cloud-computing environment. By installing this software, compromised computers with data leakage and mobile technology invasion can be prevented, thereby reducing the risk into manageable monitoring facilities (Mather et al., 2009).

The cloud-computing environment has highlighted the need for de-parameterization, wherein a collaborated oriented architecture is advocated. It is through this manner that organizations and security experts can conduct securing collaborations with various vendors and online customers. This will result in a forum-type sharing that will allow the development of technology that suits customers and organization’s needs. An open style communication system is seen to be advantageous for all concerned, as it is a mode for information sharing of security practices (Mather et al., 2009).

Collaboration forums will help organizations form partnerships with security consultants to determine the latest threats. This is especially vital in cases where organizational crime is viewed to have penetrated LAN/WAN database security systems by as much as thirty percent. This exploitation figure is only an estimate as experts cite fraudulent activities are rising by more than twenty percent globally per year. High tech criminals are estimated to profit at least $200 million dollars in combined data theft, phishing and hacking activities. The Internet is, in fact, a large area of concern for LAN/WAN database security mainly through the large number of transactions ongoing at any given time. This impacts the organization’s ability to properly do data tracking through the system (Mather et al., 2009).

The virtual characteristic of the LAN/WAN in cloud computing is evidence of its key strengths and inherent weaknesses, especially in attacks using mobile malware. Industrial espionage is also crucial with the apparent weaknesses of Web 2.0 technologies. Business models are seen to be vulnerable to attacks as they shift from traditional to cloud models creating large problem areas in terms of becoming indiscriminate victims to hacker attacks. This results in emphasizing the need for collective action by organizations under the cloud-computing environment. Protection and proper reporting is seen as a positive framework to formulate software to counteract threats. Furthermore, increased awareness of Trojan and hacker attacks is crucial in being able to build a standard database server security. Ultimately, this is viewed to be particularly important in database security as LAN/WAN systems are now integral to industry business practices. LAN/WAN systems are vital as they assure faster data exchange and efficient information storage. It facilitates ideal interconnectedness both in a wired and wireless framework (Mather et al., 2009).

Forums are expected to develop an open standards framework for cloud computing security as this is currently being supported by HP, IBM, AMD and Microsoft. The need for standardization is apparent in order to build integrity into the LAN/WAN system. A multifaceted approach is necessary in creating a security framework that encompasses many domains e.g. private, public, virtual and non-virtual entities. This multi-tenant approach is seen to be the most viable in building an end-to-end security environment (Mather et al., 2009).

Methodology


 

According to Cleveland (2009) LAN/WAN database security is customized to the various customer needs given the level of control the organization needs or requires to give up to the cloud service providers. However, this is not sufficient, necessitating the inculcation of other ways of ensuring LAN/WAN data security in the cloud computing data base. One of these ways is encryption. End-to-end data encryption adds encryption to communication paths ensuring only the intended party having the correct identity accesses the data in a LAN/ WAN platform.

For further security of data in a cloud computing system, each cloud service should be secured and must have its encryption turned on. Another way of securing a database is by the use of the Hashing Method of cryptography, where the information cannot be decoded until the person wishing to access it matches the hash value of the new message as required (Stallings, 2007). Moreover, data in databases should be backed-up using modern technologies such as RAID technologies to ensure that, in case of any eventuality where the data becomes corrupted or deleted, processes can be restored swiftly with minimum losses in data, especially in the most sensitive ones.

According to Lyon, (1997) devices connected to a LAN or connected to the Internet by means of a modem, run many services that watch both well-known and unknown ports which increase the need for secure operation platforms. Improved WAN performance adds an extra degree of security by necessitating data to be transported through distinctive pipelines that are well secured. Both LAN and WAN security implementations are beneficial for both service providers and enterprises as they appear to broaden virtual networks outside their facilities leading to these security measures enhancing higher network productivity (Cole, 2009).

The research design will be exploratory in nature, using quantitative and qualitative research methods. The use of second-hand materials such as academic books and scholarly materials will be an invaluable resource in meeting the research objectives. These objectives are to ascertain the effectiveness of forums as an ideal source of standardization in LAN/WAN database security systems and whether this is an effective tool in developing new security technologies. Second, a collection of best industry practices in security measures will be conducted to contribute to existing literature on the subject. This will add to the breadth of knowledge in applying basic security measures and complex security protocols.

The research philosophy will be descriptive: Gathering data from known technological companies and security providers. A qualitative approach will be applied in soliciting first hand sources to determine the effectiveness of current practices and security breaches if any. It is crucial to understand security concerns in the LAN/WAN system, especially gathering experiences from companies that have adopted cloud-computing environments. Furthermore, understanding the related substantive issues will be highlighted wherein the methodological design of this undertaking is viewed to be advantageous to the researcher. The final goal is to search for an optimal solution against security risks through an analytical framework.

Summary and Conclusions


 

The advantages of cloud computing are many, from cost efficiencies to easier exchanges of valuable data within multiple frameworks. Security developers today face many challenges with the large migration of organizations from traditional to open natured systems. Data protection as it travels through either a wired or wireless network is necessary. This is especially vital to assure client confidentiality and compliance for businesses. Being able to monitor data exchanges is integral to intelligent security management especially securing access from the back to front end portions of the system. Significantly, a forum will provide an avenue for all organizations and customers to develop a best practices approach that is seen to lead to better infrastructure development (Rittinghouse & Ransome, 2009).

The cloud computing architecture using a LAN/WAN system has the advantage of virtualization and application centralization, wherein in database security, it can be prioritized in order to promote further growths. Security protocols can be initiated by software systems that include firewalls and intrusion detection features that protect all network users. More importantly, the shared system creates a dynamic environment that makes it difficult for hackers to penetrate. Furthermore, this highlights the human element in database security management wherein insiders can instigate threats. A deeper understanding of basic and complex database security approaches are viewed to develop a long-term security strategy that is a progress of intelligent
