The hardware environment usually uses a blade server based on Intel or AMD CPUs to build a cluster system. To reduce costs, outdated hardware that has been discontinued is used. Node has local memory and hard disk, connected through high-speed switches (usually Gigabit switches), if the cluster nodes are many, you can also use the hierarchical exchange. The nodes in the cluster are peer-to-peer (all resources can be reduced to the same configuration), but this is not necessary. Operating system Linux or windows system configuration HPCC cluster with two configurations: ...

Cloud storage is a concept that extends and develops in the concept of cloud computing (Cloud Computing). Its goal is to combine application software with storage devices to transform storage devices into storage services through application software. In short, cloud storage is not storage, it's a service. This service can provide virtual storage on demand on the network, also known as data storage as a service (Storage, DaaS). The customer pays for the storage capacity that is actually required to purchase. Any reference to the amount of fixed capacity added ...

I. Mail is the primary breakthrough in cyber attacks E-mail security protection experience summary. As the main communication tool of the enterprise (especially the traditional and large enterprises), the mail is increasingly critical. At the same time, security issues are increasingly prominent. Due to the lack of authentication and security authentication mechanisms, e-mail protocols are inherently anti-tracing and cost-effective. Mail has become the main approach to telecom fraud and ransomware attacks. At present, the public generally believes that email security is phishing. In fact, the field of email security is very wide. This article is based on the knowledge of work and shares with you in many dimensions. ...

All of these have the potential to jailbreak or get root permissions by a Third-party application that is prohibited by the installation of a security breach. An infected BYOD connection to the corporate network is another security issue. Walking wireless eavesdroppers can steal corporate data by uploading data from BYOD to personal devices. This article will learn how to protect your enterprise assets with a security policy for a cloud-based BYOD environment. To ensure security in a cloud-based BYOD environment, you need a complete and unambiguous security policy. This article describes the potential for the escape ...
