Most enterprises need to protect internet communication. For many enterprises, the simplest way to protect communication is to use virtual private network (VPN) to create an encrypted channel between systems to communicate. The most common use cases of VPN include connecting remote staff to the central data center, allowing them to securely access the internal resources required for their work, and creating

1 Introduction With the enlargement of the scale of university running, the new (sub) campus spread to the wireless network construction and management put forward higher requirements. VPN technology can not only build a unified wireless network management platform, but also improve the security of wireless campus network. 2 VPN Overview

Today, many SaaS and PAAs (Platform as a Service) vendors and developer fanatics have adopted cloud computing. In addition, some companies have expressed great interest in their virtualization projects, but have not yet formed a wave of implementation. It's not surprising, actually. Last year, cloud computing was not even in the top 10 list of Gartner's technology. Cohesiveft's CTO, Patrick Kerpan, says: Security is a barrier to the implementation of

VPN Virtual Private Network (VPN) refers to the technology for establishing a private network on a public network. It is called virtual network, mainly because the connection between any two nodes of the VPN network does not have the end-to-end physical link required by the traditional private network, but is built on the network platform provided by the public n

1 Introduction With the rapid development of public networks such as internet and the development trend of international economic integration, there is more and more demand for the transmission of information through network between enterprises. How to guarantee the safety and efficiency of communication at the lowest cost is an issue of great concern to enterprises. The popular solution is to use tunneling technology to establish secure virtual private networks, the virtual private network (

It is particularly famous for its IPsec-based VPN applications, such: certificates can be used when configuring VPN b

2.1VPN Introduction VPN (VirtualPrivateNetwork) refers to the technology for establishing a private network on a public network. The connection between any two nodes of the VPN network is not a point-to-point physical link required by the traditional private network, but a logical network built on the network platform provided by the public network service provider ISP. User data is transmitted through a l

upgrade from one wireless technology to another without replacing the hardware. A hybrid approach may include using client software with existing Wireless AP and planning to transition to a new device-based product. Another method is to specify a server in DMZ (or in its own network segment) to handle wireless connection, VPN gateway requirements, and firewall information, and enable or disable the wireless network segment. However, by adding a virtu

reasonable, avoiding the cost of 802.1x encryption for virtual private network connections. The weakness of this method includes the high price. purchasing new machines can only meet the needs of new wireless LAN subnets, without changing hardware, it is difficult to upgrade from one wireless access technology to another. A hybrid approach may include using client software with existing Wireless AP and planning to transition to a new device-based product. Another method is to specify a server i
