新西兰信息系统学论文代写:云模型
三种类型的服务是通过云模型的SaaS,IaaS和PaaS。根据模型的使用,每一种都有不同类型的安全问题。
SaaS(软件即服务):提供按需的应用程序,如电子邮件、软件会议和业务应用程序,例如ERP、CRM和SCM(如,等人,2010)。SaaS用户对安全性的控制较少,并对安全应用程序、多租户、未启用的数据的安全性和可访问性问题引起关注。
PaaS(平台即服务)有助于促进没有购房成本为基础的应用程序部署云,有助于维护系统包括硬件和软件。PaaS依赖基础层的网络安全与网络浏览器的安全可靠的网络(Ju等人,2010)。然而,与模型中的第三方关系等问题使用户更加困难。生命周期的开发是另一个问题,从应用程序开发的角度来看,用安全托管云构建复杂的应用程序是困难的。在云中,应用程序的变化速度不仅影响系统的生命周期,而且影响系统的安全性。
IaaS(基础设施即服务)提供了资源池,如通过服务器、存储、虚拟化系统的形式,一般是通过网络访问的网络系统和其他资源的计算。云计算的所有应用程序都由拥有完全权限和完全控制的用户运行。通过这个模型,可以更好地控制云用户,但要考虑到计算、网络化和存储通过云提供商控制的基础设施的基本考虑(赵等人,2009)。这些线索主要对虚拟化允许用户开发的份额甚至迁移虚拟机以获得对系统的访问,但网络攻击的介绍创建一个问题,这个模型的层次问题。另外,在IaaS环境中,虚拟内存的图像是负责预包装的软件,包含基于文件的配置用于创建虚拟机模板。因此,这种图像对于完整的云安全具有重要意义。然而,恶意用户也有能力将包含不良编码的图像存储到破坏云系统用户的人的仓库中。

Three types of services are provided by Cloud model which are SaaS, IaaS and PaaS. In each of these there are different types of security issues depending upon the usage of model.
SaaS (Software as a service): provides on-demand applications such as emailing, software conferencing and applications of business, for example, ERP, CRM and SCM (Ju et al, 2010). There is lesser control of SaaS users on security and raises concern regarding security application, multiple tenancy, and security of data not enabled and issues of accessibility.
PaaS (Platform as a service) helps in facilitating cloud based application deployment without the purchase cost and helps maintain the layers underlying the system inclusive of hardware’s and software’s. The dependency of PaaS is on secure network and reliable network with security in web browsers (Ju et al, 2010). However issues such as relationships with third party in the model further make it difficult for users. Life cycle development is another issue as from the application development perspective; building complicated applications with security hosting the cloud are difficult. The applications speed of change within the cloud in turn influences not only the system life cycle of development but also its security.
IaaS (Infrastructure as a service) provides resource pools such as through servers, storage’s, networking systems and other resources of computing in the virtualized system form which is generally accessed through the web. All applications of cloud computing are run by the users who are given its complete entitlement and complete control. Better control is obtained through this model to the users of cloud but the underlying considerations of computing, networking and storing the infrastructure which is controlled through the providers of cloud (Zhao et al, 2009). These leads majorly towards issues of virtualization which allows the users to develop share and even migrate their virtual machinery in order to gain access to the system but the introduction of cyber attacks is creating a problem to the layers of this model. Also, in the environments of IaaS, an image of virtual memory is responsible for pre-packaging the templates of software that contain file based configuration used for creating the VMs. Therefore, such images are significant for the complete cloud security. However, malicious users also have the capability of storing images that consist of bad coding into repositories of people that compromises the cloud system users.
