"Cloud security," Is it really safe?

As if overnight, almost all the software manufacturers have sprung up their own "cloud security." The emergence of cloud security as the saviour of the security world has greatly improved the ability of anti-virus software. At present, each family has described its own cloud security is unusually outstanding, although it is the choice of words, but a little attention to their talk can find that the description is almost the same thing. Below, I show you the anti-virus company "cloud security" before and after the update of the virus library step contrast, we know what "cloud security" is what.

Cloud security, as its name suggests, is a term that evolves from "cloud computing". Through the relevant introduction of Google search to understand: "Cloud Security" program is the latest manifestation of information security in the network era, it integrates parallel processing, grid computing, unknown virus behavior, and other emerging technologies and concepts, Through the network of a large number of client-side software behavior of the abnormal monitoring, access to the Internet Trojan, malicious program of the latest information, pushed to the server for automatic analysis and processing, and then the virus and Trojan solution distributed to each client.

Before Cloud security appears:

The user reports the virus sample, through the virus engineer's analysis test, if identifies as the virus, namely to this virus sample extracts the characteristic value, joins in the virus storehouse, gives the user to upgrade.

After Cloud security appears:

A collector is installed on the client, and once the collector discovers the suspicious file, it automatically uploads the suspicious file to the server, and then the virus automatic Analysis system automatically analyzes the suspicious file and extracts the feature, adds it to the Virus sample library and automatically upgrades it.

By contrast, it is not counted as "cloud security", depending on whether "suspicious files are found on the user's computer and uploaded automatically". And no matter how large the number of servers in the real sense of cloud security is, simply "extracting suspicious files from the user's machine" makes most users feel conflicted. Imagine the consequences if you collect personal privacy, business documents, or procedures on your machine as "suspicious files" on the server.

The fact is that the technological revolution, or another concept of speculation, I believe that everyone has been very clear. Lenovo a few years ago, the security vendors are also a night to say that they have joined the "active defense" function, after testing proved that the manufacturers of these followers are mostly just a part of the function of hips after the beauty of its name "active defense" to hype it.

Slowly found that the security industry is now gradually focused on the "entertainment", you today out of the "cloud", I will be a "cloud security" tomorrow, you study the discovery of the universe of "dark energy", I found that the operating system of "dark security", as if nothing is unwilling to fall after the people, are interested in the blending of one. Rising is directly renamed as: Beijing Yi Jin Yu-Hui Technology Investment Co., Ltd., it is to make people laugh and cry. Can we trust antivirus software?

Cloud computing is the future of security in the realm of the Savior, or Sodom hype, I believe that the majority of users have seen very clearly. Integrity, is any company should have the basic quality, if the lack of this, and then how to the concept of a swap, the results can only be like Sanlu, Baidu and other lost hearts and minds.
