Ssl vpn has been a major technology since its appearance, allowing enterprises to greatly reduce their remote access fees and provide specialized transaction services through the Internet. VPN brings great commercial value. However, only when such a premise is met can this value be realized, that is, it can provide appropriate levels of protection, make sure that enterprise information is accessible only by authenticated users. To this end, it must be able to provide a powerful authentication barrier that can actively identify each user and network integrity, so that data transmitted over the Internet will not be tampered.
Through Special encrypted communication protocols, ssl vpn establishes a dedicated communication channel between the staff on a business trip at one end of the Internet and the company headquarters at the other end, which is like setting up a leased line. Compared with traditional VPN solutions, ssl vpn is easy to maintain and does not need to change the existing network structure. It has strong mobility and unordered security client programs, and has powerful access control capabilities, mobile users can easily access the company's internal B/S and C/S applications and other core resources.
As a traditional solution, remote access is completed using the leased line dial-up connection. Although this method works quite well, its most typical defect is that the transmission speed is low, and the huge network cost also makes it difficult for you to provide the services they need. However, ssl vpn allows you to fully apply the powerful functions of the Internet to remote access. Using this method not only significantly reduces costs, but also improves work efficiency, service quality, and the ability to access information anytime, anywhere. At present, many vendors have launched their own ssl vpn products. However, an ideal ssl vpn solution should have the following five features.
1. Powerful security assurance
We say that SSLVPN is a dedicated channel between the company's mobile staff and the company's headquarters. The data transmitted through this channel is internal enterprise data and is not public. Therefore, remote connection must be performed on the premise of security. Taking SafeNet iGate4.0 as an example, the security includes three layers: one is the security of client access, and the other is the security of data transmission; third, security of internal resource access.
For remote mobile users, we recommend that you use the iKey + PIN code for authentication. IKey is a USB hardware device that identifies a user. It is the same as a bank card used on an ATM. It can pass authentication only when the iKey is inserted and the Correct PIN code is entered, it does not work if you have an iKey or only know the PIN code. Second, after a legitimate user passes verification to connect to the company's Intranet, the security of the client device becomes the core of the entire LAN. Although the internal network construction is very strong, mobile users can use laptops and PDAs to log on to the company's internal system as public computers in Internet cafes, whether or not the client device has installed the Personal Firewall anti-virus software has become a key point for hackers to intrude into the enterprise. SafeNetiGate has a special client detection function. It can scan the firewall and anti-virus programs installed on the client and determine their security levels to determine whether the device meets the access conditions, ensure the security of the entire system. Third, after a mobile user completes remote access, hackers or criminals can steal company secrets by copying and copying data residing in the client buffer. To this end, SafeNetiGate can automatically CLEAR user buffer content after the user is offline. In addition, access is automatically interrupted after the iKey is removed.
2. Support full application connection
The earliest SSLVPN product only supports the remote connection of Web applications. Because most enterprise applications are very complex, enterprises often not only apply B/S-based applications, it also needs to use traditional C/S applications and other non-TCP applications, such as UDP, which restricts the development of SSLVPN to a certain extent. With the development and upgrade of products, SafeNet iGate now supports full-network connections, including TCP-based B/S, C/S, and UDP applications, such as WebDav, SMB file sharing access, standard email protocol, Lotus Note, Telnet service, remote terminal, Citrix, etc.
Iii. Ease of management and maintenance, and strong operability
One of the outstanding advantages of SSLVPN is its strong mobility and ease of use. However, these features often increase the management difficulty. The SafeNetiGate interface is simple, easy to use, flexible, and meticulous in setting access permissions. It uses a user/group/role-based authentication mechanism. Each file, website address, or application can be set separately, makes access control easier to manage. At the same time, SafeNet iGate can also directly use the existing user database for authentication and permission allocation, so it can make better use of existing resources and greatly reduce the work intensity of administrators. For all remote access, iGate automatically records the access time, session activity, and warning information through the reporting tool. administrators can describe the access time, session activity, and warning information in charts by date, usage, or group.
4. Do not reduce the running efficiency by processing SSL
Because it is a centralized system, SSL Acceleration determines the throughput of the entire network. If SSL Acceleration cannot keep up, remote access will be much lower than the actual Internet access bandwidth. SafeNetiGate uses dedicated SSL Acceleration hardware to increase the response speed of the VPN. In addition, using data compression technology, iGate compresses all transmitted data before transmission, which improves the efficiency and practicability of the entire network.
5. Stable Operation and no network interruption
The stability of access is another key factor that allows users to access remotely. Users cannot tolerate frequent network interruptions. Too many functions sometimes affect access stability. SafeNetiGate optimizes all functions to ensure good system stability.
