Whether cloud security can bring security to LAN

At the beginning of 2009, the major anti-virus software manufacturers to upgrade their security products to version 2009. Along with the version of the upgrade, security companies to hype their own products in the "cloud security" concept. In fact, previously on the "cloud security" concept has been repeatedly seen in the media, security companies have been actively for its debut. Although the concept of "cloud security" varies from home to house, there is no difference in nature. According to their claim, cloud security makes the internet a huge "anti-virus software", the more participants, the more secure each participant, the entire Internet will be more secure. National defense, the era of the Trojan horse has arrived. According to this logical reasoning, the Internet has become an "antivirus factory", the factory implementation of the principle of distribution according to work, who pay more benefits will be more. As we all know, the LAN between the personal client and the Internet, the "cloud security" for this community what is it? 1. LAN brings "cloud security" what? Cloud Security "is based on a large number of client-supplied virus samples, and then through the virus automated analysis system to analyze suspicious files and extract features, added to the virus library, and finally through the Virus Library update service to more users. There are only two ways to deploy security software in an enterprise: One is a stand-alone mode, the enterprise through the purchase of products authorized for each client deployment anti-virus software; One is the service pattern, the enterprise buys the corresponding Enterprise Edition, then carries on the server-side and the client's deployment separately. Either way, the large number of clients in the LAN provide a large number of virus samples for "cloud security," which expands the security vendor's virus base, and the security vendors benefit a lot from it. In addition, "cloud security" seems to pass all the risks to the enterprises, enterprises need to bear certain risks. Because, in order to obtain a virus sample security vendors usually do is to install a similar collection or reporting of information on the client tools, the so-called virus sample collection. Although security vendors claim that the tools are "found on the user's computer and automatically uploaded", who can guarantee the privacy of the machine, and even the company's trade secrets as "suspicious file" was uploaded? In "Cloud security" mode, the individual, Enterprise client is weak, who can guarantee the legality of collecting host information? "The emergence of cloud security" so that every computer becomes a Trojan monitoring station, who can monitor this? 2. What does "cloud security" bring to LAN? The above analysis shows that the LAN for "cloud security" at least pay the traffic, and at the risk of personal privacy, trade secrets are compromised, and security firms have benefited a lot. Is the interest equal? What does "cloud security" bring to the LAN? If it is true, as the security companies say, "Cloud security" for users, enterprises "bring real benefits", but also bale. But the reality is: Virus manufacturers through a group of numbers claimed to collect Trojan, virus samples hundreds of thousands of per day, hundreds of millions of clients to provide it with so many virus samples, but thisThe benefits seem not to feel at all, but virus, Trojan but endless, enterprise network management for this complain. It can be said that "cloud security" does not bring any tangible and obvious benefits to the LAN. Perhaps the security firm will say: "Cloud security is still in its infancy!". But, as the current security firm's hype claims, the technology is already very mature, and has greatly benefited the people. This kind of contradictory practice, can see some safety manufacturer's impetuous, the commercial interest is supreme, has fooled the populace to be suspected. Security companies are calling for "united to be Safe", yes, hundreds of billions of clients have banded together to provide you with virus samples, but are you ready? For example, does the virus analysis system sound? Has the mechanism for new threats been promoted? How to eliminate the possibility of "cloud security" the disclosure of personal information? Is there a different strategy for cloud security for different clients (individual users or businesses)? In addition, now the so-called "cloud security" or the manufacturers fragmented, can only be regarded as a "lone cloud", how the manufacturers can achieve real "cloud security"? Summary: Remember 2008 security Vendors Hype " Active defense ", the 2009" cloud security "whether the concept of speculation or new technology, we hope it is not" The Emperor's Clothes ", can bring real security for users.
