"Cloud" volume "cloud" Shuyun security know how much?

In the cloud era, the application of cloud technology has been deep into various fields, as people on the computer and network widely known, cloud concept is also popular, but if the "cloud technology", many people are still confused, and do not really understand cloud technology.

If the word "cloud" is simply described, it can be viewed as a transit point for data. In this transit station, people can store and handle all kinds of data from the network for their own services. As for the difference between a private cloud or a common cloud, it is possible to differentiate between "public" and "private" as long as the network of data exchange is counted.

Thanks to the limits of physical storage and data processing, cloud technology, with its huge "support", is increasingly popular with individuals, businesses and even government agencies. It can be said that under the support of modern cloud technology, the development of enterprise Informatization will move towards a new height. But this kind of "stimulant" general information technology, its bring not completely is the good aspect, because the cloud technology to the data exchange and the storage particularity, regarding its security protection question has been the enterprise CIO headaches.

How is the security of the cloud defined?

By definition, cloud and self-built data centers are not much worse in terms of security. The news storm, triggered by the NSA, started as a story about "cloud computing security," and later turned into a comprehensive discussion of security. It turns out that the NSA has been able to eavesdrop on physical servers in physical data centers and has invaded many of the world's security organizations.

Therefore, cloud security and the physical world, as well as the need to take appropriate precautions, naturally, the cloud is the standard of security can also refer to the "Physical world" standards.

Is the data safe to enter the cloud?

migrating applications and data to the cloud will shift part of the responsibility from your own data center to the cloud provider. This is similar to outsourcing behavior. This would therefore involve the transfer of control, and the resumption of control involved relevant procedures and techniques.

In some ways, cloud computing is revolutionary, but on the other hand it is developmental. The study of risk-control needs to be understood first. What we learn in the data center naturally evolves to the cloud, but it also requires the proper process. Many technologies are also evolving naturally.

So you should start planning existing programs and security-related technologies to learn how to evolve them into the cloud. In many cases, you will find that there is a corresponding relationship.

But you will also find that certain areas are truly revolutionary. Because the cloud has no walls, the physical security of the data center does not work in the cloud. The cloud also involves the employees of the cloud provider, so you need to try to control those who don't work for you. These are obvious changes that require new technologies and procedures to deal with.

What are the main strategies for protection in the cloud?

Continuing the topic of cloud development and change, many aspects of cloud security are familiar to us. Firewalls, antivirus, authentication--These are all included in the cloud. You will find that cloud providers often offer solutions in these areas, and traditional vendors are also improving their solutions.

But some aspects may change your mind. Because the cloud doesn't have walls, and the employees of the cloud provider can view your data--you have to create an invisible wall for the data. In a cloud scenario, data encryption is the best known solution for these problems.

By the way, data encryption can also meet the needs of traditional data centers-most data leaks occur internally, so the threat is not just from the staff of the cloud provider. However, threats from within the cloud environment are a new focus on data encryption, which is beyond doubt.

The only change from the traditional data center to the cloud data center may be the diversity of data encryption protection needs, and in order to adapt to this variety of requirements, the same "flexible" multimode encryption technology may be the best choice.

With the combination of symmetric algorithm and asymmetric algorithm, the Multimode encryption technology can ensure the quality of encryption, and the Multi-mode feature allows users to choose the encryption mode and more flexibly to deal with various protection needs and security environment.
