Virtual Private Networks: IPSec Vs. SSL by Michael Daye Jr. on 19/04/07

In today’s society organizations and companies are expanding globally from region to region. Employees working from home offices are also becoming very popular, which organizations benefit financially by utilizing less office space, and reducing total expenses incurred by having office workers on site. With this expansion, organizations develop a need to communicate with these offices over highly secure, confidential, reliable connections regardless of the location of the office.

VPNs or Virtual Private Networks are used by many organizations and companies to fulfill the need to communicate securely and confidentially over the internet with its employees and offices outside the corporate network. A VPN creates a private and secure connection, known as tunnels, throughout systems that use the data communication capability of an unsecured and public network—the Internet. VPNs use secure protocols to provide private communications over the Internet; they also connect the private corporate network to homeoffice employees, or to a remote business site through virtual connections routed through the Internet. Organizations which decide to use VPNs as their means of secure communication, would choose between the more commonly used IPSec and SSL secure protocols. Both protocols have their advantages and disadvantages; the deciding factors between the two depend on the infrastructure of the corporate network, its specific security requirements, costs, and reliability.
