The router is an important bridge for the LAN to connect the external network, is an indispensable part in the network system, and also the Frontier Gateway of the network security. But the maintenance of the router is rarely appreciated. Just imagine, if the router even its own security is not guaranteed, the entire network there is no security to say. Therefore, in the network security management, the router must be properly planned and configured to take the necessary security measures to avoid the security problems of the router to the entire network system to bring loopholes and risks. We are here to introduce some of the router to enhance the security of the measures and methods, let me ...

In this article we cover a VXLAN over IPsec configuration using FortiGate as VTEP.

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 ...

Cloud computing is already a very hot concept, involving a very large number of services, flexible computing services, file storage services, relational database services, key-value database services, and many others. This article will briefly explain the security issues of elastic computing services, as flexible computing is the most commonly used cloud service and also the cloud service with the highest security risk. 1. Introduction Since many things involve corporate secrets, technical details, implementation or new directions, this article does not explain. Interested can vote for a resume, we work together for cloud computing. 2....

In the past, servers, storage, and networks can be managed separately because they can be viewed as relatively independent domains. 　　In recent years, due to the large number of server virtualization applications, the construction of Dynamic Data center or cloud computing data Center has become the primary choice for enterprises, the integration of servers, storage and network is the trend. 　　But in the practical application, the virtualization technology in the storage and the server application is very widespread, the network as an important link, already obviously lags behind. Virtualization requires network transformation Traditional data Center network architecture is divided into Access layer, convergence layer and core layer, ...

Cloud Management is a hot topic, and it is popular that every start-up and established vendors provide some tools to manage the cloud environment. There are monitoring tools, configuration tools, and tools in between. There are naturally foggy pieces on the market (vaporware), and it is not easy to get a clear idea. If you deploy a cloud that is fairly static or not a mission-critical environment, you may not need to configure the system dynamically. In this case, the product's built-in standard tools for adding/changing/removing resources may be more than sufficient. Several vendors have products designed specifically for cloud computing management (...).

Cloud management is increasingly well known and is becoming a hot topic for now, with every emerging company and established vendors providing some tools to manage the cloud environment. There are a wide variety of tasks, such as monitoring tools, configuration tools, and tools in between. On the market there are natural fog (vaporware), this kind of tools to dazzle people, want to quickly have a certain understanding and clear, it is not easy.
