of pure technology is not comparable, only the combination of a full network of security policies can effectively enhance security. In network management, because most enterprise users do not have enough ability to manage IP network, and want and willing to entrust the network to the NSP to manage, so the difference of network management level is mainly the difference of operator network and management level, In fact, if there is engaged in Network management agent maintenance of professional f

technology can bring the following benefits to enterprises and service providers: Companies that adopt remote access have paid in advance all the fees for purchasing and supporting the entire enterprise remote access infrastructure;Companies can use the ubiquitous Internet to provide staff and business partners with secure and secure connections through a single network structure;For enterprises, the exist

difficult to achieve. SSL VPN does not exist at all, the enterprise can even limit a partner to access only some pages and folders in a site, and do not need to modify the partner's security policy, as long as partners have access to the Internet. Current form SSL VPN is becoming a hot market with the increase of web application and the increasing demand of remote access. Although most remote access serv

, the data through a secure "encrypted channel" in the public network spread. Companies only need to rent local data lines, connect to the local public information network, all over the organization can communicate with each other, at the same time, enterprises can also use the Public Information network dial-up access devices, so that their users dial to the public information online, you can connect into the enterprise network.

Run the route command to view all the routes. Route The result is roughly as follows: Kernel IP route table destination gateway subnet mask mark hop reference using interface default 192.168.8.1 0.0.0.0 UG 0 0 255.192.168.8.1 255.255.255.255 UGH 0 0 0 wlan0110.185.76.107 192.168.8.1 255.255.255.255 UGH 0 0 wlan0link-local * 255.255.255.0.0 U 1000 0 0 0 wlan0192.168.0.40 * 255.255.255.255 UH 0 0 0 ppp0192.168.8.0 * 255.255.255.0 U 2 0 0 wlan0 Configure all traffic to go through the

Future enterprise video applications, including remote negotiation and videoconferencing system, can be realized.The convergence of future businessWith the in-depth application of IP, the contradiction between application and bandwidth will be intensified. Netcom 40G Backbone network bandwidth, can fully adapt to future IP applications to the demand for large bandwidth.The demand

The tunnel protocol is divided into the Layer 2 tunnel protocol and the layer 3 tunnel protocol based on the Layer 2 or Layer 3 tunnel of the OSI model. Layer 2 tunnel protocol: the Layer 2 tunnel protocol encapsulates the entire PPP frame in the internal tunnel. The existing Layer 2 tunnel protocols include:PPTPPoint-to-Point Tunneling Protocol): Point-to-Po

local networks of different branches by leasing various types of long-distance lines to telecommunications companies. However, the cost of leasing long-distance lines is expensive, which is hard for most enterprises to bear. Virtual Private Network VPN is a new technology that has emerged in recent years. It can not only free enterprises from heavy network upgrade and maintenance work, but also make effect

, servers, and agents of business outlets, and other devices are not allowed to access the network. In the new system, the "TPN Gateway" and "TPN client" form a linkage defense system, avoiding functional bottlenecks formed by a single gateway defense system or a single client defense system, this reduces the IT department pressure on enterprises. Wang jinghui, Senior Product Manager of shenzhou.com, once explained that the boundaries between centralized security and distributed security are vag

For example, business settlement among major supermarkets 3) Internet companies VPN between multiple IDCs to serve business management and business access between different IDCs, data f

consultation is unnecessary, really reach to even even, to break. 4) Full Control of the initiative VPN enables enterprises to use NSP facilities and services while fully mastering the control of their own networks. For example, companies can give dial-up access to NSP to do, by themselves responsible for the user's identification, access rights, network address, security and network change management

VPN (Virtual Private Network) is no longer a simple encrypted access tunnel, it integrates multiple functions such as access control, transmission management, encryption, route selection, and availability management, and plays an important role in the global information security system. Also on the network, the advantages and disadvantages of various VPN protocols are benevolent, wise, and wise. For the pur

With the development of network communication technology and the emergence of network applications, more and more user data and enterprise information are transmitted over the Internet. As a result, more and more hackers and cyber threats are emerging. they steal, tamper with, and destroy confidential and sensitive data to achieve their ulterior motives. Therefore, with the development of network communication technology and the emergence of network applications, more and more user data and ente

Using the Internet egress line to establish a VPN channel to achieve the interconnection between the total and branch offices is currently a popular solution for many companies. In the past, to establish such a VPN, at least one end must use a static IP address. Currently, many companies use the ADSL method to access t

----------------------- Openvpn is an open-source VPN software used on LINUX gateway servers. as its name implies, openvpn is used to connect a secure virtual private channel, allowing users to remotely work and obtain intranet resources. The software can be used across platforms in Linux, xBSD, Mac OSX, and Windows. openssl is used as the encryption library and the encrypted certificate or user name/password is used for identity authentication, is a

an information system based on the C/S or B/S architecture through the background database. The OA system has the characteristics of process transfer. It must pass the approval of each link before it can be transferred to the next link. However, if the company's leadership or other department leaders are on a business trip or going out to the public, the OA system will not be able to flow normally, affecting the company's daily operations. On the other hand, some group

(3) It is used in the form of communication between subsidiaries and parent companies. 8. Benefits of Using VPN (1) cost saving, because you only need to use existing VroYou can.
