Privacy/security implications of unexpected https:// connections

It has recently happened to me more than once: I just visit a website, or click on a link (not a bank, or credit card payments!), and quite unexpectedly I am connected through a https:// connection.

It has been quite a while since I studied the subject, but if I recall correctly, a https:// connection, while keeping third parties out, gives the other party at the connection complete/(a lot?) access to your computer. Correct ?

So, how much should I be concerned about this ?

Last time it happened, I was reading a website with news reports, clicked on a link, and suddenly noticed the https:// connection that had been established (in this case, a USA military naval organization). I can't say I appreciated it.

 

I have never heard that assertion made before and, quite frankly, I find it hard to believe.

 

My understanding of HTTPS connections is that the communication between PCs is encrypted. That is pretty much it. Elevated control of the PC\site hosted would of course depend on what is required and or allowed to interact with said site.

 

There's no real difference between http and https regarding the access a site gets to your PC. How much access a site can get is determined by how they use java, javascript, flash, and other interactive content, which work equally on http and https. Https is strictly for keeping others from snooping. Usually https is used when personally identifiable or financial info is sent or accessed, but some sites use it for no obvious reason.

 

Actually, I was thinking of THIS (I just did a search):

Seriously, I'm OK ?

 

If i remember correctly, he is warning about firewalls/proxy programs that filter content, that possibly don't filter https.
The program 'needs' to be able to filter https besides normal http.
