Why You Must Get IPSEC VPN?
IPSEC or Internet Protocol Security is a model designed for the set of rules or protocols for secure network or the packet processing layer. This is designed for network communication. Application layer in the communication framework already has the security that was set earlier. IPSEC proves to be helpful when you implement or use IPSEC VPN or the Virtual Private Networks. This is also helpful for remote user access via dial up to connect to the private networks. Another good advantage of IPSEC VPN is that all the security systems can be dealt without monitoring or changing every individual’s computers. One company that has been top achiever in making IPSEC VPN a world standard is Cisco.
If we talk about the past years, let me tell you that if a remote organization or office requests to connect with the main network or the computer at company HQs that meant setting up of committed leased lines between headquarters and remote offices. The fast and secure dedicated leased lines between the remote offices proved to be beneficiary but they were expensive too.
In order to fit the mobile users, firms would have to implement committed dial-in RASs, i.e., Remote Access Servers. Remote Access Servers would use one or more modems and the firm would have a phone connection that was connected to each modem. All the mobile customers could use the network by it, but the network speed was as slow as a tortoise. In return this made it very tedious to complete all the productive work.
As the internet came up, many changes have take place in the world across. If a web of network and servers pre exists, connecting all the computers of the world, then why would a firm expend bucks and develop administrative problems by installing committed leased lines and dial up networks using modem. Internet can be used now for the same purpose.
Well if there is the internet then how can you isolate the internal network from the public Internet and still your remote network users are able to access the public internet as way to get them connected to the company network? You can install a free IPSEC VPN client or the virtual private network. The VPN makes a virtual “pipe” that joins two endpoints. Traffic inside the pipe stays encrypted so that the public internet does not access the intercepted information. By installing IPSEC VPN client software, a firm can give access to private network to its clients across the globe.
