Big Data + cloud computing makes security, privacy a paradox

On the one hand, the United States government has always been keen to show the embarrassing situation, on the other hand, the public on the network of Information and communication security and personal privacy protection of the topic again warming.

Our inability to discuss national security issues seems more like a diplomatic affair, a process of game-playing among politicians. Even Huawei CEO Ren, who said he was no longer on the initiative to expand the U.S. market, also showed frustration-he hinted: "The water is deep, not one of our private enterprises can be steered."

Security, privacy and convenience seem to be paradoxes. U.S. President Barack Obama said, "You can't have 100% security in the same time, with 100% privacy and 100% convenience." "(You can don't have 100% security in, also super-delegates 100% privacyand 100% convenience.) Logically speaking, Obama is right. That, of course, is the best excuse for the American government to absolve itself.

But the important thing is whether we enjoy the convenience of the Internet at the same time, must be at the expense of security and privacy?

"Security and privacy are relative and need to be defined by specific criteria," an anonymous network security personnel said to me, "for the general public, do not arbitrarily let oneself become the target of cyber attack is the best choice to protect security, if it is pure attack and defense, it becomes a spear and shield game." "People like free, but there's a price to pay for free, and there's no doubt that the biggest price is personal information." ”

The problem of security and privacy is not so much a problem of network technology as a moral and legal problem. From a technical standpoint, when your information is out of your sight and placed on a third-party server, it is difficult to control who is exposed to the eyeball and how it is used.

In fact, hackers, Internet security people, and even the creators of Web apps--software engineers--are mostly "internet hermits". Yes, they created the world of the Internet and helped businesspeople create countless business values, but they became "bystanders" on the edge of the Internet.

In the big data age, people's sharing desire has been promoted to the extreme. In the past, you just put some irrelevant pieces of information online, and now you're anxious to move the entire computer's hard drive to the public network. "For most users, security and privacy issues are caution when the software experience is extreme," said the security personnel, "but when you wake up, it's not under your control." ”

To get people back to the age of no networks? That is impossible and unrealistic. "The future of a private cloud is likely to be a choice for many," he said. said the security person.

A few years ago, Amazon Vice President and Web architect James Hamilton that private cloud computing had no future because of its inability to achieve the scale effect of shared cloud computing. In the following years, Amazon rapidly developed into one of the world's largest third-party cloud platform service providers, most of whom are face to face individual users, security and privacy requirements of the commercial web site and users. However, as people become more aware of security and privacy today, the private cloud deadlock could be broken.

First of all, multiple devices, small scope of sharing demand for personal private cloud provides a space for development. Now families with mobile phones, tablets, and more than two PCs are growing. The data communication between these devices would be a serious waste of bandwidth through the public cloud network, and in fact their convenient communication needs are becoming increasingly strong. The way in which data is transmitted through the public cloud is eliminated, and it is likely to be a private cloud-link between individual devices.

In terms of the scope of information sharing, private cloud can meet the needs of most people. Most people just want to share information within a manageable range of individuals. This circle can be small, small, a few members, large thousands of people, private cloud for this small-scale sharing is both rapid and effective. A shared cloud is best served by millions of people, or even hundreds of millions of people sharing services, which are equally inexpensive in a small coterie of shared applications--and the cost of servers and bandwidth is not cheap at all. For private cloud-sharing, the only challenge is to keep a terminal online in the sharing circle-which today doesn't seem to be a problem.

Second, private cloud can greatly enhance people's security and privacy protection. As we said before, the best solution to security problems is not to be the target of attack. Private clouds are much more secretive than the catches public cloud. Attackers have no time or interest in attacking private groups of little value, and they may not even know "who you are, where you are". But the public cloud is different, the more popular the Web site, or the more aggregated data applications, the more likely to become hackers target-they are looking for may not be you, but you unexpectedly become a by-product of their attack results.

Third, at the technical level, the private cloud can already communicate across the Internet. Private cloud is no longer an isolated island of information, and when needed, the "private cloud" can communicate with the outside world by coordinating the server.

However, in the business model, private cloud services are facing innovation. Because no longer holds user data, private cloud providers still exist in the traditional way of charging for services. While the private cloud is far lower than the public cloud in cost, it can operate at a lower cost, but it may be a while before the custom-free user chooses to pay for the service. The ability to innovate an Internet model suitable for private cloud development will be a key factor in determining whether private cloud applications can be scaled up.

For individuals, the "cloud" of the future Internet should be the state of "public-private", where 80% of the information should be present in a proprietary cloud. If you are concerned about your network security and personal privacy, then from now on, you may have to consider a little control of your sharing desire!
