It's secure enough. The login is handled by a client side script that
negotiates a connection to https://lsc.ims.mnscu.edu before the login form
data is submitted.

I suppose it might be a tad more secure to have the page that presents the
login form sent securely because someone might be able to "man in the
middle" attack that page, and replace the script with a bogus one, but if
they have that ability it's not going to be much harder to just attack the
whole HTTPS connection anyway.

I missed the js login entry. All I noted was post method. Ignore my
previous post, it apparently was in error.

The page is not secure for several reasons but the most glaring issue is
the password login is passed via post method in the clear. This
could be potentially intercepted using several methods or entry points.

I a school environment I would definitely change post login method being
used, it is a tempting and easy target.

Some times the page has to be opened in a new window to see the actual
encrypted (SSL) page, but it all depends on how the set up is made, if
you open in a new window and you don't see the SSL, I wouldn't trust
it.

Its badly designed as although it is secure, it does not look that way
to the user.
