How to make remote access more secure Virtual Private Network

[Abhirath]

As the enterprise information technology development and the web2.0 era, the traditional method has been in office not keep up with the changing needs, mobile office, soho office office gradually become the mainstream way. Compared with traditional office methods, mobile office and soho office has brought a more flexible working hours and office location, for timely access to the latest and most valuable information a great help. In this information age, who can control the information the first who will be able to control the final victory, so remote login, remote access to modern working life started to become a necessary demand? So I need to know how make the remote access more secure Virtual Private Network.

With the remote login, remote accesses to a gradual increase, network security issues are also beginning to show up. Open remote login may give companies a tremendous threat to network security are likely to result in the loss of confidential information and, if so, then a bit more harm than good by remote login. In order to ensure the security of remote access, virtual private network VPN bred born, it had improved the security of the entire network, in order to capture more valuable information to lay a secure foundation.

Virtual Private Network VPN, defined through a public network (usually the Internet) to establish a temporary, secure connection, is a public network through the chaos of the security, stability tunnel. Through a virtual private network VPN can help remote users, branch offices, partners and distributors, such as establishing credibility within the secure connection, ensuring the security of data transmission, so that both can get the latest information, expand the amount of information, but also ensures that communication between timeliness, the most important is that it let's really the "internal" environment is more secure and reliable.

IPSec VPN using IPSec protocol is simply to achieve a kind of remote access VPN technology, IPSec is the IETF (Internet Engineer Task Force) to develop safety standards, IPSec protocol is a wide-ranging, open and virtual private network security protocol, which provides all data on the network layer protection, providing a transparent secure communication. Be pointed out that IPSec is based on the network layer and cannot be through the usual NAT, Firewall.
SSL VPN uses SSL protocol is simply to achieve a new type of remote access VPN technologies. SSL (Security Socket Layer) protocol is proposed by Netscape WEB-based application security protocol, which includes: server authentication, client authentication, SSL link on the SSL link data integrity and confidentiality of data. It is worth mentioning that, SSL protocol is built into IE and other browsers, use the SSL protocol for authentication and data "encryption SSL VPN can be installed from the client, simplifying the operation of the client.

An authentication, IPSec uses Internet Key Exchange (IKE) method, through the digital certificate or a set of keys to do authentication; while SSL only the use of digital certificates, so if both authentication using digital certificates, then they authentication security level is almost the same. The user control, IPSec can clearly use the revenue control equipment access to mobile users; while SSL is used beyond the control of the user equipment access.

SSL VPN application simple and does not require configuration, you can immediately install quickly achieved; its client does not require complicated installation, because the browser embedded in a SSL protocol; its good compatibility with IPSec vpn on different operating systems require different client software is different, SSL does not require such a completely trouble.
SSL VPN over IPSEC VPN more secure, SSL security channel is point to point connection, so it is on the LAN or outside the network data is not transparent, as the same as described above, SSL little chance of attack by hackers, virus infection the possibility of very low, even if the infection is also only a single host, will not affect the entire network.
