SSL (Securesocketlayer) is a secure communication standard primarily used for the web, located between the transport layer and the application layer. Data is encrypted as it flows through it, again to TCP/IP, and the data from the TCP/IP into its first layer is decrypted, and it can verify the identity of both ends of the network connection, it provides a security mechanism to ensure that the HTTP transaction in the transmission is not monitored, forged and tampered with. SSL is now the de facto standard for securely transmitting data over the Internet, and this protocol is integrated into every common ...

Research on the privacy protection of document-oriented database based on SaaS the Kang Jin of Shandong University This paper first proposes a document-oriented database privacy protection architecture, which, on the basis of the original SaaS architecture, creates a new SaaS service deployment architecture by adding a privacy layer between the application layer and the storage layer. This architecture decoupling the privacy protection system from the SaaS application system. In this architecture, the privacy protection system is transparent to both SaaS applications and database systems. Then, this paper introduces the basic method of privacy protection based on the face document database, in order to adapt ...

As an early application of GIS industry, the land industry has saved a lot of resources, including data and functional resources. Through the construction of land information, resources have been sorted out, but because of the different GIS platform used in various provinces and cities, there is still a problem of inconsistent function interface and inconsistency of data format. For example a province uses is a platform, b format data, B province uses is the C platform, a format data; C Province may use the B platform, c format data ... 　　In turn, it leads to low service sharing and repeated construction in the same level or across the level of the land sector. In the "Land and Resources information" 10 ...

Recently, the news media is more focused on cloud computing, so you rarely hear about high availability. 5 years ago, the IT community was very focused on high availability and cluster development. But in the near term, things are different. In any case, high availability remains one of the key topics in the IT world, says Kai Dupke, senior product manager at SuSE. It has a greater emphasis on cloud computing flexibility and low-cost advantages, so high availability topics seem to be rarely mentioned in cloud computing information. In the past, UNIX and Linux platforms have traditionally assumed most of the high availability (HA ...).

The threat of information security is quite extensive, hacking, server or employee computer malware infection, confidential data theft is only a few of the common ways, however, the current enterprise it in day-to-day operations, the more fear but also can often face the threat is distributed service blocking attacks (DDoS), Because once your external network, application server suffers from such attacks, it will not function properly. It is recommended that the webmaster use the DNS service provided by domestic professional services, such as Dnsdun, to ensure the stability of the site analysis. DDoS attacks are not these ...

The key to success or failure of a public cloud service is whether they provide equal or better levels of performance, security, and reliability than the services provided by the enterprise's internal data centers. Gartner predicts that in 2013, the global public cloud market will reach $131 billion trillion, compared with $111 billion last year. To provide the market with the required performance, security, and reliability, cloud service providers are rapidly building virtualized, multiple data center service architectures, or "no walled data centers." Cloud service providers are using cloud computing to orchestrate software to unite businesses ...
