RE: IPv6 deployment excuses

This is a non sequitur.

In what way is the blocking of incoming unsolicited connections not a "proper security measure"?

What gives you (or anyone else) the right to "disable" security measures which you (or anyone else) consider "too 
strict"?

How do you arrive at the conclusion that disabling unsolicited incoming connections to software that does not require 
it (and which you do not want to accept such unsolicited incoming connections) is "far less effective" than "proper 
security measures" (and what are those alleged "proper security measures)?

Explain especially in light of built-in crapware which cannot otherwise be removed from the system because it has been 
"integrated" by scattering its parts (with no purpose other than to make the crapware non-removeable) into critical 
components so as to prevent removal without breaking the system?

Please explain how expecting firewall setting to remain set as they have been deliberately set makes one a "security 
zealot"?

If the ACLs on your Cisco router suddenly decided to change all by themselves because Cisco had decided they did not 
like the way you had set them, I am quite sure that you take an entirely different position!

Security that is too strict will be disabled and be far less effective
than proper security measures. Security zealots are often blind to that.

Yes, the default is "on". An exception is added for EVERY SINGLE PIECE of
Microsoft Crapware, whether it is needed or not (and in every single case,
it is not). And if you turn those exceptions "off", then they are turned
back on by Microsoft and their NSA partners for you, without your
permission, whenever automatic updates run (and also at other times that I
have not determined the trigger). You must continuously check that the
firewall (although ON) remains configured as you configured it, or if
Microsoft (and their NSA partners) have changed the configuration without
your permission.

Of course, most people do not bother configuring the firewall and do not
wonder why every piece of Crapware has in incoming exception, and do not
bother to turn those off (including some on this list apparently). So they
will never notice these nefarious doings which have been a hotbed of
discussion on the Internet for many years.

And this is on the latest distribution of Windows 10 including the
upcoming anniversary edition and has been that way since at least the
first version of Windows 8.

Whether or not Windows 7 also behaves the same way I do not know because I
never ran it.

Windows 8 and 10 with the most recent service packs default the firewall
to on with very few inbound exemptions.

There is no difference between IPv4 and IPv6 when it comes to
firewalls and reachability. It is worth noting that hosts which
support IPv6 are typically a lot more secure than older IPv4-only
hosts. As an example every version of Windows that ships with IPv6
support also ships with the firewall turned on by default.

Just because the firewall is turned on does not mean that it is
configured properly.

Every version of Windows that ships with IPv6 support also ships
with the Firewall configured in such a fashion that you may as well have
it turned off.

This is especially true in Windows 8 and later where the firewall is
reconfigured without your permission by Microsoft every time you install
any update whatsoever back to the "totally insecure" default state --
and
there is absolutely no way to fix this other than to check, every single
minute, that the firewall is still configured as you configured it, and
not as Microsoft (and their NSA partners) choose to configure it.

All versions of Windows 8 and later whether using IPv4 or IPv6 are
completely unsuitable for use on a network attached to the Internet by
any
means (whether using NAT or not) that does not include an external (to
Windows) -- ie, in network -- statefull firewall over which Windows,
Microsoft, (and their NSA partners) have no automatic means of control.
If you allow UPnP control of the external statefull firewall from
Windows
version 8 or later, you may as well not bother having any firewall at
all
because it is not under your control.
