Xp fw only protects you from incoming packets.
Just like any other software packet filter running on the same machine.

If the malware is active on your machine, it can deactivate any
"Desktop Firewall".
And burglars can pick locks, so there's no point in locking your door.

Wrong conclusion. The real one:
Since locks on your door are trivially picked, you should not take locking
your door as a security measure. Deposit your values in a safe!

So your safe doesn't have a lock on it? How thick are the walls on your safe?
Are they heat resistant? Does anybody have unnecessary access to the contents of
the safe? Does anybody have unnecessary access to the safe itself?


A locked door is merely a sign "I don't want you to enter my house without
permission." and only keeps of casual introducers (those with no
lock-picking tools/experience). Basically, this is because your insurance
company demands it for providing your house insurance. I just wonder...
hasn't the fence around your plot of land the same purpose?

Since casual intruders are the majority of the perps out there, cutting them out
is not a bad idea. Someone good enough and with enough motivation will
anticipate your security measures and break in no matter what you do.


Beside that, there is no analogon to lock-pciking for the digital world.
Security against a certain scenario is purely binary there, there is no
equivalent to a nuclear bomb which opens everything.

Are you saying that the digital world has no connection with the physical world
it is in?
