Can my internet service provider track what websites (not only the content but the actual domain/URL) I visit when I’m using a proxy?
is a proxy safe to prevent man-in-the-middle attacks?
A proxy is a legitimate man in the middle device. You send your request to the proxy and the proxy fetches it for you. The proxy can monitor the communications. Especially if they require them to install their certificate
Are you using your ISP DNS server IP’s in your router?
You might want to change that.
A proxy doesn’t prevent man-in-the-middle attacks. There are two kinds of these attacks that affect Internet browsing:
First kind is server impersonation. If you access a site with an insecure connection (http), man-in-the-middle attacks are still possible on both sides of the proxy. A secure connection (https) prevents these attacks with or without a proxy.
Second kind is a phishing attack. If an attacker fooled you into accessing a different server (for which the attacker has a legitimate certificate) and is proxying content to/from the server you think you’re accessing, that attack works even if you’re using https and your own proxy won’t be preventing it either. You can avoid these phishing attacks by not clicking on inbound links in your email, knowing what the correct domain is for your destination, and actually checking the URL to know it’s correct.
It depends when you use your providers dns server he can theoretically see what pages you visit
