The task execution code security mechanism in the open cloud computing environment Xu Xiaolong Yang Geng Wang Ru cloud Computing can fully aggregate the computing resources of Internet network server and edge terminal nodes for greater benefit. However, the deployment of the computing task to the user terminal implementation has brought security risks. The behavior of the massive terminal nodes belonging to different users is obviously unreliable and the computational security is difficult to guarantee. In particular, a user terminal node that acts as a task performer may tamper with program code or data in a task, returning false results,...

November 30, 2012, Beijing Network Royal Nebula Information Technology Co., Ltd. in Beijing convened a cloud computing security products "Royal Cloud" of the results of the exhibition. At the meeting, the network Royal Nebula Product director De Weiheng to the participants more than 10 media friends to share the "royal Cloud" products achieved, showing the "Royal Cloud" product advanced performance.

More and more different cloud computing applications are creating a "golden" that stores data encryption engineers. Encryption has always been an important security tool, but in most cases we have not used this tool frequently to protect stored data. 　　 This has changed since the advent of cloud computing and the impact of numerous public data leaks. Currently, the reason for using cloud computing encryption may not be as you think. The most common idea is that your cloud services administrator should protect your data (mainly public cloud computing). ...

Objectively speaking, the online payment certification Keypasco This solution raises a question that deserves deep thinking, namely whether we need to continuously upgrade and invest in hardware for security, can we realize online identity security authentication through the new way of cloud service and low cost? Online payment security issues have been a lot of attention, a brief summary, the following three aspects can be seen online payment security in the next few years may become increasingly headaches. One is the growing number of online payment users. CNNIC released the 30th China Internet development Form ...

Security issues are still a major restraint in the deployment of cloud computing resources in the enterprise, and a Gartner analyst says the biggest problem is not that data could be corrupted in the cloud, but that cloud outages could occur, leading to data loss. Gartner Cloud security analyst Jay Heiser says there is a view that the biggest risk of using cloud computing is that key data may be compromised, but we rarely see such a scenario. In 2011, Sony was exposed to data leaks, involving tens of millions of customers in its cloud, also appeared ...

IaaS provides users with computing, storage, networking, and other basic computing resources on which users can deploy and run arbitrary software, including operating systems and applications, without the user managing and controlling the underlying infrastructure, but controlling the operating system, storing, deploying applications, and having network components such as host firewalls The ability to have limited control over permissions. 1, customer data controllable and data isolation. For data leakage risk, the resolution of such risks is primarily through data isolation. There are three ways to achieve data isolation: first, let customers control the networks they need to use ...

Now, more and more enterprises are deploying desktop and server virtualization technology, all kinds of racks, computing, storage, network and other resources are integrated into the resource pool. And the future trend is also towards the "smaller performance is stronger, less energy consumption, simple and easy to use" development. However, as enterprises move more from the physical platform to virtualization, cloud service creation and deployment is becoming more and more convenient, security has become a top priority issue. So, in the cloud environment, how to effectively protect the virtual system? Below, we provide you with the following ten tips: First, the traditional security control can still be used in the transition to virtual ...

Chris Weitz, a head of Deloitte Consulting, is primarily responsible for the financial Services Consulting team's recommendations for cloud computing. He has been in this position for five years, before working for a Deloitte Global consulting service for nine years. He has over 30 years of experience in the IT field. As a result, Weitz has witnessed the impact of cloud computing on the IT industry. In a recent survey by Deloitte on the challenges of implementing a mixed cloud environment, 950 people voted, 49% voted for cloud security and data confidentiality, and he believes that the main cloud providers are actually much better than people think. ...

The field of information security hides a dark secret from us: We are fighting a losing war and losing our position at an alarming rate in the form of data leaks. This is not because we are not trying to protect the assets of the enterprise, but because it is a simple fact: the attackers have more time and tools to attack than our defenses. Some enterprises simply do not have enough money to invest in the resources needed for information security programs, while others try to deploy "half-baked" information security programs to meet compliance requirements with minimal personnel and budgets. Visible, we are fighting a war and ...

Cloud computing is another major technological change in the field of information after computers and the Internet. While the advent of cloud computing provides new opportunities for development, the security of cloud computing remains a serious challenge. Since 1994 the State Council promulgated the "People's Republic of China Information System security Regulations" (State Council [order 19,941,147th), Information system security level protection system gradually perfect mature. Has played a significant role in the traditional architecture of the information system. The advent of cloud computing has brought a series of changes in the architecture of the system, but no matter how it develops, it belongs to the letter ...

The general view is that 2012 is the year of China's cloud computing practice. Indeed, this year is China's cloud computing from concept discussion to landing practice, from technology-driven to application demonstration of the key year. In the government, operators, cloud services and users of the joint efforts of the entire Chinese cloud market has been rapid growth. In terms of the number of companies offering cloud computing services, only a handful of companies in 2011 were able to provide more sophisticated cloud products and services, and this year more companies joined cloud computing service providers to promote the development and prosperity of cloud computing. Many companies that have traditionally provided IDC services have also been ...

The first problem that cloud security faces is the technology and management problems in the virtualized environment. Traditional protection mechanism based on physical security boundary is difficult to effectively protect user application and information security based on shared virtualization environment. In addition, the cloud computing system is so large, and mainly through the virtual machine to calculate, in the event of failure, how to quickly locate the problem is also a major challenge. Secondly, it is the problem that the service model of cloud computing separates the ownership, management and right of use of the resources. Cloud computing, a new service model, separates the ownership, management, and use of resources.

Researchers at the Georgia Tech Information Security Center recently released a 2013-year network threat forecast detailing the most serious computer security problems they see in the coming year. Cloud computing is first on the list: using cloud computing for malicious purposes. The flexible configuration that allows legitimate business to quickly add or subtract computing power can also be used to quickly build a powerful zombie computer network to complete an attacker's various ulterior motives. Microsoft Windows Azure Outstanding Engineer Yousef Kh ...
