More secure alternative to VPN

Virtual Desktop Interfaces like GoToMyPC can be more secure than VPNs for remote workers.
As workers become increasingly mobile, they’re demanding access to their computers–both at home and in the office–from whereever they can connect to the Internet. Cube rats want to access their home computers. Road warriors need to connect to their office desktops to maintain their productivity while traveling. Linking to headquarters is essential for telecommuters.
Over the last decade or so, the vehicle for establishing secure connections outside a company’s firewalls has been the Virtual Private Network, or VPN. It allows a remote computer to tap into a corporate network by creating a secure tunnel to it through the Internet. This method, though, can have security risks. That’s opened a market for alternatives to the hoary VPN.
Because VPNs originate with a company’s IT department, their operation is unquestioned by their users. After all, the reason users are told they need to use the VPN is so they can connect to headquarters securely. That creates a false sense of safety among users so they’re likely to transfer sensitive data through the VPN without using additional encryption and deploy protocols that transmit authentication credentials without any protection at all.
How to secure your network using IPSec

In another post I spoke of VPN and using secret keys to secure communications. VPN stands for Virtual Private Network and if you work for a large company or do business with a large company then chances are you log in to your network via a Virtual Private Network. A VPN is a network within a larger network such as the Internet or a company LAN. But the VPN is not characterized by the physical wires. Instead the VPN uses open connections or virtual circuits through the larger network.
VPNs can enable secure communications over the public network by using authentication or encryption. One of the ways to secure communications of the VPN is by using what is known as IPSec.
IPSec is short for IP security and is a secure VPN protocol. IPSec is defined by the Internet Engineering Task Force.
