SSL VPNs and Using OpenVPN
For a very long time, people in information security have thought IPSec is THE VPN and SSL is for secure online banking. While SSL has traditionally been used for Web site security purposes, SSL’s applications reach wider than just web proxying and application security.
Traditional SSL VPN started off with products that were more like SSL gateways instead of true VPNs. These products cannot be really termed as VPN but more like “Secure Remote Application Access”.
They thrive on a management faзade called “Clientless VPN”. A VPN that can be established with any web browser without installing a software component sure promise less pain for users and administrators alike, but it comes with certain caveats that we will talk about later.
In the past, IPSec has been used as THE technology to create a VPN Site-to-site or site-to-client tunnel. IPSec has since long enjoyed widespread implementation because of its monopoly on function, although it has received its fair share of criticism for being too complex, and tightly coupled with Operating System.
