is secure before logging on is one of the most important steps because the end user
wants assurance that his logon username and password are encrypted.

First, the SSL VPN administrator must keep in mind is that the HTTPS Web
portal needs a valid and secure enough certifi cate attached to it. The way to do
this is to make sure the new IAG gateway has a new certifi cate attached to it and
that the certifi cate is valid for a long period. It is suggested to request a certifi cate
be issued for a two-year period or longer. Second, the administrator should make
provision for users accidentally connecting to the Web portal with HTTP instead
of HTTPS. The way to do this is to create a Redirect HTTP to HTTPS Trunk
in the IAG.
Depending on the end user??™s Internet browser, the certifi cate will be accessible
when the end user browses to the IAG Web portal.
