SSL, set, and PGP are the most commonly used encryption methods on the Internet (i), and they have a large user base within their scope of application. This article will introduce the three popular encryption methods in detail. The SSL (secure Socket Layer) SSL protocol, first published by Netscape, is a secure transport agreement for network data, with the primary purpose of providing a secret and reliable connection between two communications. The protocol is made up of two layers, and the bottom layer is SSL on a reliable transport protocol (for example, TCP) ...

The increasing security risk not only drags down the firewall, it also drags down the antivirus system. "Traditional malware detection methods based on signatures are not enough," said Charles Kolodgy, director of research at IDC's Security product Services Division. The user's behavior is changing, the threat is evolving, but the malware detection technology has not kept pace. "The safety of new ideas security vendors are in urgent need of a new idea to solve this problem, at this time is seen as the future direction of network security cloud security, and it can be a counterweight to the Web security gateway." The generality of both ...

The relationship between big data and cloud computing has caused some confusion. In order to facilitate the discussion of the relationship between the two, from the "calculation" and "data" of the historical relationship. Because cloud computing is first a kind of "calculation", large data is first a kind of "data", and computer is used to "calculate" "data". Computers are software-and hardware-separated, a software-defined electronic product (programmable). An important issue in computer design is how to effectively manage hardware resources such as CPU, memory, and I/O, and how to make these resources reasonably available to applications. These two major tasks are embedded in various ...

Virtualization vendors may be promoting the potential of putting 20, 50, or even 100 virtual machines on a single physical server, but IT managers and industry experts say these ratios are dangerous in a production environment, causing performance problems or worse disruption issues. In the test and development environment, companies can put 50 virtual machines in a single physical host, said Andimann, vice president for research at Colorado State Boulder's Business Management Association (EMA). However, when it comes to important tasks and resource-intensive applications, the virtual machine ...

Traditionally, a business needs to develop a disaster recovery plan based on their respective recovery-time objectives (RTO), enabling them to recover operations within a certain amount of time. Typically, this may involve rebuilding infrastructure and applications over a period of more than 72 hours, and handling the purchase and deployment of tangible assets. In reality, this process may take a longer time. Downtime for critical applications is by no means an option, and people always recommend a full redundancy, http://www.aliyun.com/zixun/aggregat ...

Wired magazine recently published an article named Clint Finley (Klint Finley) explaining how Apple "killed" the Linux desktop. The article points out that the real reason for Linux failure is that developers are turning to OS X, and the reason for this is that the toolkit used to develop Linux applications is not doing well enough to ensure backwards compatibility between different versions of the application Interface (API). More importantly, developers are turning to the web for development work. The following is the full text of this article: it is difficult to ...
