To secure browser which is very fragile, the approach of HTTPS Only 3.1 is
exceptionally simple:
1. Only HTTPS URLs(no other protocols)
2. Whitelist of domains(anything outside of whitelist is blocked)
Now, let's look at threats:
1. Man in the middle - it's fixed.
2. Phishing always requires the browser to load attacker's website, so it's
permanently dead here.
3. Drive-by Download - dead(if applied strictly, unable to download the
executable)
4. Clickjacking - dead(attacker's web page is unreachable)
5. Address Spoofing - dead too(just unable to load the fake content)
6. XSS - almost dead(for attacker, the XSS vulnerability has to be GET, because
POST requires attacker's HTML)
7. CSRF - almost dead(for attacker, the CSRF vulnerability has to be GET, and
modern web applications simply don't do important things in GET, because it can
be bookmarked etc, too dangerous)
