云计算同时呈现多个机会和障碍。在面临的所有障碍中，安全性被视为云计算成功路径中的关键限制（Puthal等，2015）。云计算方法中的安全问题本质上是广泛和动态的。数据的位置是云计算安全性的另一个重要组成部分。位置的透明性是云计算突出的灵活性，同样是对安全性的威胁。由于不知道具体的数据存储位置，某些地区的数据保护措施可能受到严重影响，可能被认为是违规（Dillion等人，2010年）。云用户的个人数据安全因此是云计算环境中的一个重要问题。在组织数据和个人信息安全方面，云提供商的战略政策被认为是非常重要的，因为认为单一的技术安全性不足以解决问题。另一个增加安全问题的问题是利用云服务的信任因素，因为它直接与云服务提供商的真实性和可信性挂钩。建立信任被认为是开发云计算成功环境的关键（Hashem等，2015）。在云计算中，信任模型提供具有高度的本质性，因为它是任何云计算实例的利益相关者中共同感兴趣的领域。

云中的信任因素取决于各种因素，其中一些因素是人为因素，自动化管理，策略和流程。云信任不是技术安全问题，而是云计算内在安全性内在问题驱动的最具影响力的软性因素（Islam et al。，2016）。计算机网络内的各种适用的攻击和在途数据适用于基于云的服务。这是因为这个框架内的某些威胁被归类为中间人的攻击。这还包括类似的网络钓鱼，嗅探，窃听和其他攻击。分布式拒绝服务被称为DDOS是最常见的攻击之一，但却是主要的云计算基础设施攻击。这种众所周知的攻击可能会给云计算带来潜在的问题，因为它的缓解措施没有任何例外（Pasupuleti et al。，2016）。虚拟机的安全性很大程度上决定了云环境的安全性和完整性。认证，计费和加密都是安全计算实践的一部分，它们可以被纳入云计算安全的关注范围之内。但是，安全和风险问题在这方面是非常重要的。例如，供应商的锁定可以被视为基于云的服务中可能的风险因素，而不必与安全性方面相关（Subashini and Kavitha，2011）。另一方面，特定操作系统类型的使用可能对基本上被认为是安全风险的安全性构成威胁，这样的操作系统可以是开源的或专有的。根据Mark（2009）的观点，云计算中的其他组织风险实例可以被视为服务不可用，许可问题，供应商的业务不连续性，从技术角度来看，这并不属于安全问题。因此，根据Mariam（2010）的观点，安全的担忧总是被认为是一种风险，而任何风险都与担忧无关。在云计算基础架构中涉及的各方之间的责任分配可能导致面临不一致，这可能导致最终的安全漏洞实例。类似于任何其他网络的情况，内部攻击提供在云计算内仍然是有效的威胁（Rittinghouse和Ransome2016）。在云环境中使用的任何安全工具或软件都可能存在安全漏洞，这会对云计算本身的基础架构构成安全风险。第三方API与垃圾邮件发送者的问题是云计算环境的威胁。

The cloud computing is presented with several opportunities and obstacles in a simultaneous manner. Out of all the obstacles that are faced, security is regarded as a critical limitation for the cloud computing within its pathway to succeed (Puthal et al., 2015). The security concerns in the approach of cloud computing are wide and dynamic in nature. Location of the data is another crucial component within the security of cloud computing. Transparency of location is cloud computing’s prominent flexibility that is a threat towards security in the same instance. As not knowing the particular data storage location, the data protection act provision for certain areas may be critically affected and it can be considered as violation (Dillion et al., 2010). The personal data security of the users of cloud is therefore an essential concern within the environment of cloud computing. In respect to the organizational data and personal information security, the cloud providers’ strategic policies are regarded as extremely significant as it is considered that sole technical security is not sufficient to resolve the concern or the problem. Another problem that increased the concerns of security is the factor of trust to utilize the cloud services for the reason behind its direct link to the cloud service providers’ authenticity and credibility. Establishment of trust is regarded as the key in developing a successful environment of cloud computing (Hashem et al., 2015). The trust model provision is of high essentiality within the cloud computing since it is a common area of interest among the stakeholders of any cloud computing instance.

The trust factor within the cloud is dependent on various elements out of which some of them are human factors, management of automation, policies and processes. The cloud trust is not an issue of technical security but it is the soft factor which is of most influential nature driven by the inherent issues of security within the cloud computing to a higher extent (Islam et al., 2016). All sorts of applicable attacks within the network of computer and the in-transit data are applicable to the services based on cloud. This is because certain threats within this framework are classified as attacks by man in the middle. This further includes phishing, sniffing, eavesdropping and other attacks of similar manner. Distributed denial of service known as DDOS is one of the most common attack but it is major cloud computing infrastructure attack. This well-known attack can cause potential issues for the cloud computing as there are no exceptions for its mitigation being considered as an option (Pasupuleti et al., 2016). The virtual machine’s security defines the level of security and integrity of the environment of cloud to a great extent. Authentication, accounting and encryption all are part of the safe computing practice, they can be included within the concerns for cloud computing security. However, it is of high importance that the concerns of security and risks are distinguished to this respect. For an instance, lock-in of vendor can be regarded as possible risk factor within the services based on cloud that does not have to be associated to the aspects of security necessarily (Subashini and Kavitha, 2011). On the other hand, usage of particular operating system type can pose threat to the security that is essentially considered as security risk, such operating systems can be open source vs. proprietary. According to Mark (2009), other instances of organizational risk within cloud computing can be regarded as unavailability of service, licensing issues, business discontinuity of the provider which does not lie within the concerns of security from the technical standpoint. As per Mariam (2010), therefore, the concern of security will always be considered as a risk of some manner while any risk is not associated with the concern of security. Responsibilities allocation amid the involved parties within the infrastructure of cloud computing may lead to facing inconsistency that may result in eventual instance of vulnerabilities within security. Similar to scenario of any other network, the insider-attack provision remains a threat of valid nature within the cloud computing (Rittinghouse and Ransome 2016). Any tools of security or software utilized within the environment of cloud may have loopholes in terms of security that will pose security risks to the infrastructure of the cloud computing itself. The issue with the APIs of third party along with the spammers are the cloud computing environmental threat.
