Why it was hijacked website? What influence?

　　As long as there is interest there is, all things are there will be someone to do it, not to mention the site to hijack such a thing.
　　In fact, for hijacking the site, we can completely ironed out before things happen.
　　Use iis7 site detection , often in their own time available, enter your website domain name to the server check, I think it is a very necessary thing. Because it can greatly improve the chances of timely detection of the problem, then you can first time to resolve.
　　Impact of hijacked
　　from two kinds of operators caching features point of view, both by acquiring user data traffic, to guide users to access content cache server. The difference is that guide the user's way, by modifying the DNS resolution is forced DNS record, direct all requests under the force of the domain name server to hijacking. This simple and crude way, are likely to cause many problems. For example, dynamic content under the domain name will be cached. This will cause problems serial number of login. Cached content updates are not timely, accessible to all the old content. This is also unacceptable to many users place. Some popular cache resources, will result in a waste storage. Traffic hijacking user traffic needs to be mirrored manner, analysis and judgment. Some systems can be determined caching cached hot content. DNS forced resolve mainly for pictures, 302 Jump major file for downloading files, audio and video.
　　Operators benefit applications can bring hijacked systems are:
　　reduce access across the network transmission and reduce the cost of inter-network settlement between operators. Various parts of the country, operators are independent operations, daily Internet traffic is generated by the need for cost settlement. And this cost is actually a large sum of expenses, but also need to continue settlement.
　　Most exports between network operators are ranging from tens to hundreds of G, content caching system can effectively reduce the export bandwidth of the network peak pressure, this can reduce the expansion of the exchange network. Reduce the cost of network construction.
　　Because caching system can support localization services, to a certain extent, it can also achieve the purpose of speed up network access, enhance the user experience.
　　Since the system operation and maintenance personnel can not get timely updates to hijack the content, or the content of hijacking do other downside is:
　　always have access to the content expires, file updates slowly. Resulting in less access to information they want.
　　Jump to other web pages, or psoriasis is inserted into the ad.
　　In order to reduce the impact of cache and operators to bring hijacked, many companies started using HTTPS way. Requires all domain names before including Apple must be HTTPS, then HTTPS fundamentally solve this problem? Through the above analysis, it is clear that can not effectively be addressed. https because of the use of encryption and decryption means to ensure the possibility of content being tampered with is reduced, but in principle operators hijacked, it can not effectively reduce the possibility of being hijacked.
