Cloud Computing Security Vulnerability Risk Identification Method

In less than a decade, cloud computing has evolved from an interesting new concept into a major mainstream market. The industry's expectations for the future of cloud computing are generally higher. Morgan Stanley predicts that Amazon Web Services (AWS) will exceed the $24 billion annual revenue threshold by 2022. Of course, the success of any single vendor's cloud computing business depends entirely on its ability to help users eliminate concerns about cloud computing security, and related issues still arise in some on-demand deployment projects.

"The highly-virtualized, multi-tenant environment is more vulnerable to attacks" is based on the belief that the high level of accessibility and flexibility that cloud computing has so appealed to customers has opened the door to opportunity for malicious hackers.

These concerns about cloud computing vulnerabilities often affect whether customers move their most important applications to cloud computing decisions. However, there are signs that cloud computing security has become less and less of an obstacle to the development of cloud computing. The glamour of on-demand models is so great that many companies are willing to put down concerns about data security and privacy, and use project-based infrastructure as a service (IaaS) deployments to support the demand for short-term resources, at least on an experimental basis. .

The good news of the gap in self-confidence is that the next wave of cloud computing deployments has achieved considerable success, which helps to increase users' confidence in using this model. However, there is still a gap in confidence between companies that have not yet used cloud computing and those that have used cloud computing. Research firm comScore Inc., commissioned by Microsoft and conducted a survey of more than 200 small and medium-sized enterprises (SMBs), found that 42% of companies that do not use cloud computing services believe that cloud computing is fundamentally unreliable. In contrast, in a survey conducted in June 2013, 94% of small and medium-sized respondents stated that they used cloud-based applications with a higher level of security than they had implemented internally. These findings strongly support the view that many companies actually found that one of the most compelling benefits of cloud computing is that suppliers can provide a degree of expertise and integration security, which is much better than many companies themselves. The level of internal implementation is higher. In short, security is a key differentiator for cloud computing vendors.

So, what kind of cloud-specific vulnerabilities and threats are the most dangerous and how can suppliers best protect their cloud computing environment? The reality is that neither the general nature of security threats nor the risk of deployment and migration There are fundamental differences between the type and the traditional environment. Attackers tend to follow similar patterns and use the same methods that have traditionally been used in traditional environments: Bypassing access control, discovering valuable data, controlling the assets in which data resides, and stealing or revealing data. However, the intrinsic nature of cloud computing means that vendors need to adapt their methods to solve the specific problems of the on-demand environment.

Using a layered approach to reduce the negative impact of cloud computing vulnerabilities Just as they protect traditional IT environments, cloud computing vendors need a multi-layered approach to comprehensively addressing security issues. This approach will integrate multiple technologies into one, such as Management, perimeter security and threat management, encryption, distributed denial of service (DDoS) mitigation, and privacy and compliance management. However, in a shared cloud computing environment, components such as identification and access management have become particularly important because data from multiple customers is stored in the same shared environment and is shared by the same shared environment. access. Cloud computing vendors need to ensure that customers can provide an efficient solution that can not only authorize access, but also use methods such as multifactor authentication in virtual environments for authentication.

Vendors also need to address the issue of hypervisor security through the use of monitoring tools that can detect suspicious behaviors, including abnormal traffic patterns and abnormal trading behavior. These abnormal phenomena may mean an impact. Environmental integrity threats. Vendors also need to answer questions about data mix from both privacy and compatibility by describing how they logically differentiate customer data.

Many hackers will launch large-scale attacks on the cloud. The purpose is to overload the environment and expose loopholes. At this point, the supplier needs to take correct DdoS mitigation measures so as to find abnormal traffic before the attack behavior affects the environment.

In addition, in a multi-tenant environment, vendors need to ensure that companies that migrate application workloads from traditional environments have properly configured communication settings for several factors—including encrypted or non-encrypted data channels, IP addresses, and hosts. Names - so they are transmitted over a secure channel.

Vendors face a series of challenges when it comes to protecting cloud computing data, but in fact the real test is learning how to communicate effectively with customers. This will involve introducing security controls and highlighting suppliers’ response to vulnerabilities. content.

The success of cloud computing depends on many factors. While issues such as price and data geographic location are important, the true ability of cloud computing providers lies in its ability to be a trusted partner for its customers, not only providing the appropriate infrastructure, but also being able to change due to its commitment. Trustworthy.
