For remote Wan users, the virtual private network (VPN) should be a secure connection, but many enterprises question the security of VPN due to many obvious vulnerabilities. RainerEnders is the CTO of NCPengineering for VPN security in the Americas. In this article, we will learn how VPN security vulnerabilities are ge

Virtual Private Network (VPNVirtual Private Network) is defined as a temporary and secure connection established through a public Network (usually the internet). It is a secure and stable tunnel through a chaotic public Network. VPN relies on ISPInternet service providers) and other NSP network service providers) to establish dedicated data communication networks in public networks. In a virtual private network, the connection between any two nodes is

VPN routing technology mainly uses tunneling technology and encryption methods. Here we mainly analyze how to use the VPN route table to use both the optical fiber access network and the telecom network. If you use IP address verification, and it is not suitable for normal ADSL and other dynamic IP address users, it is not convenient to use MAC address verification, because many ADSL uses a router to access

ADSL is called an asymmetric digital user line. ADSL is called asymmetric because its two duplex channels are used to transmit data to users, and only a small portion of bandwidth is used to send user information back. ADSL supports the upload speed of kbps on a copper-to-copper line ~ 1 Mbps, 1 Mbps ~ 8 Mbps, valid transmission distance between 3km ~ Within the range of 5km.Application of ADSLAdsl lan users have four fixed static IP addresses. enterprises applying for access through the adsl la

Application of SSL VPN SSL VPN provides a variety of remote access services to the enterprise. Introduce the following common services: E-mail: For enterprises, e-mail communication is a very basic function. IPSec VPN protects the messaging system, but IPSec VPNs need to install client software and connect to the corporate network before they can use an interna

SSL BasicsWhen most of the current remote access solutions use a VPN Network Based on the IPSec security protocol, A new study shows that almost 90% of enterprises use VPN for Intranet and external network connections only for Internet access and email communication, in addition, 10% of users use non-Internet applications such as X11, chat protocols, and other private client applications. These 90% applicat

Various iOS devices (iPhone, itouch, and iPad) use their own VPN servers to access the Internet and leave the proxy alone. Device used for testing: Windows XP Computer + iPad Available places: for example, in the school living area, connect to the VPN Server set up by yourself in the teaching area to access the Internet (of course, if you have the permission to involve these machines, you should not bothe

The full name of VPN is "Virtual Private Network ). As the name implies, a virtual private network is a virtual private line within an enterprise, it can establish a temporary and secure private communication line between two or more intranets located in different places on the Internet through special encrypted communication protocols. A Virtual Private Network is an extension of the enterprise intranet. It can help remote users, branches, business p

VPN is one of the most important technologies in the access network. As the access network technology continues to develop, VPN is also evolving to meet more user needs, it brings people a convenient and fast network environment. The emergence of VPN is no longer overnight. From IPSec to SSL, VPN has undergone a lot of

VPN we can understand it as a virtual out of the enterprise internal line. It can establish a proprietary communication line between two or more enterprise intranets that are connected to different places on the Internet through a special encrypted communication protocol. The virtual private networking function is to establish a private network on a public network for encrypted communication. VPN gateways e

It's not easy to install VPN client under FEDORA9 The data found that there are two ways to install, one is through the NETMANAGER-VPNC, the other is through the Pptpconfig At first I was ready to pass the Pptpconfig way, but later found that pptpconfig can not be directly installed through Yum (online), if not through the Yum, you have to involve a lot of rpm, so give up, take the first line, because Netmanager in the F9 is ready-made, On the top o

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 enterprise cloud computing. Despite the fac
