“…Moreover, the compliance and QoS are under the control of the organization [62,148]. A hybrid cloud is a combination of public and private clouds, and tries to address their limitations while maintaining their features [119,136]. The main purpose of a hybrid cloud is usually to provide extra resources in cases of high demands, for instance, to enable migrating some computation tasks from a private to a public cloud [147,148].…”

The adoption of cloud computing has increased dramatically in recent years due to attractive features such as flexibility, cost reductions, scalability, and pay per use. Shifting towards cloud computing is attracting not only industry but also government and academia. However, given their stringent privacy and security policies, this shift is still hindered by many security concerns related to the cloud computing features, namely shared resources, virtualization and multi-tenancy. These security concerns vary from privacy threats and lack of transparency to intrusions from within and outside the cloud infrastructure. Therefore, to overcome these concerns and establish a strong trust in cloud computing, there is a need to develop adequate security mechanisms for effectively handling the threats faced in the cloud. Intrusion Detection Systems (IDSs) represent an important part of such mechanisms. Developing cloud based IDS that can capture suspicious activity or threats, and prevent attacks and data leakage from both inside and outside the cloud environment is paramount. However, cloud computing is faced with a multidimensional and rapidly evolving threat landscape, which makes cloud based IDS more challenging. Moreover, one of the most significant hurdles for developing such cloud IDS is the lack of publicly available datasets collected from a real cloud computing environment. In this dissertation, we introduce the first public dataset of its kind, named ISOT Cloud Intrusion Dataset (ISOT-CID), for cloud intrusion detection. The dataset consists of several terabytes of data, involving normal activities and a wide variety of attack vectors, collected over multiple phases and periods of time in a real cloud environment. We also introduce a new hypervisor-based cloud intrusion detection system (HIDS) that uses online multivariate statistical change analysis to detect anomalous network behaviors. As a departure from the conventional monolithic network IDS feature model, we leverage the fact that a hypervisor consists of a collection of instances, to introduce an instance-oriented feature model that exploits individual as well as correlated behaviors of instances to improve the detection capability. The proposed approach is evaluated using ISOT-CID and the experiments along with results are presented.

“…Such resources are offered, maintained and upgraded by third parties who own and manage them without any effort or involvement of the end users who just need to have minimal knowledge about how to access it, how to use it and how much it will cost. And this is the simple definition of cloud computing adopted by many authors, such as Armbrust et al (2010), Hajjat et al (2010), Mozammel-Bin-Motalab and Shohag (2011), Saini et al (2011) and Senica et al (2011).…”

“…There are private clouds that are specified to a certain organization, community clouds shared by a community or a group of organizations, public clouds generally shared by the public and hybrid clouds which represent a mixture or combination of two or more types of clouds Armbrust et al (2010) and Senica et al (2011). This is explained in Figure 1 which represents the main types of clouds.…”

“…It is widely believed by authors that the services offered by cloud computing can be divided into layers representing the types of services including the Software as a Service (SaaS), the Infrastructure as a Service (IaaS), and the Platform as a service (PaaS) (Saini et al, 2011) and Senica et al, 2011).…”

This paper provides a framework for comparison between the in-house implementation of ERP systems versus the in-cloud implementations. The paper first establishes a framework for the comparison based on three factors: pre-live, i.e., the implementation methodologies of both options; post-live, i.e., cost, time and the user-friendliness of the systems; and other factors, i.e., security and scalability. Results show that in-cloud systems are faster to implement, less costly and easier to use and scalable. In-house system, compared with in-cloud, gives organizations more control and hence many organizations deem them more secure.
