Wouldn't the programs you give as examples be designed for it, for example it is possible to set up interprocess communication or have threads to communicate with each other but that's a design that has to be intentionally coded (for example a debugger probably has some access to the programs memory because it is the parent of the child process).

Your second paragraph I find a bit hard to follow. I segmentation fault will occur if a process tries to read memory not belonging to it, the memory management unit would see to that. Are you saying sometimes there can be a bug and a fault doesn't occur and it can be read?

Ok thanks that clears things up

comment Basic question about why it's useful to have VPN encrypt traffic
So in a really short nutshell, since the routers and servers the packets pass through are owned by people you don't know they could have been setup in a way to read your packets?

comment Basic question about why it's useful to have VPN encrypt traffic
A huge pet peeve of mine is using metaphors to explain things. They should only be used in the most complex of examples. For instance, in the article it says using WEP to secure wifi is like speaking in pig latin. This basically says nothing.

Ok so if you pay AT&T for your internet connection, it may pass through telecommunication devices not owned by them? In that sense what difference does your ISP make, if you're paying them and using equipment they don't even own?

@Ulkoma why do you find it necessary to use the word "third"? For example, if I were to replace all the times you say "third ISP" with just "ISP" what difference would it make?

"They belong to a third ISP" how do you count third? alpha has an ISP, beta has an ISP (though it may be the same as alpha), and now you're saying yet another ISP owns the public routers?

@Ulkoma ok. So are they public routers they pass through between the home router and the ISP? Who owns them, for example are they technically property of the ISP and are just lacking security so anyone can eavesdrop on them?

Sorry, I can't understand anything you say.

comment How can a VPN use a virtual router and not send encrypt traffic and still be safe?
@R15 yes we were talking about MPLS before VPN so that very well may be it. I realized I may have a whole in my understanding. security.stackexchange.com/questions/73589/…

comment What is the purpose of yubikey
You say the password changes every minute. Are you using it as an example or is it actually one minute?

comment What is the purpose of yubikey
What does mean "server"? So Yubikey and the password manager (e.g. Keppass, Lastpass) both know the secret seed and the algorithm (which is open source so is public knowledge) and using the seed and the current time both calculate a deterministic output. Is my understanding correct? If an attacker gained knowledge of the seed, then they would be able to create the password for any time, and yubikey would be defeated? What prevents that from happening?

comment What is the purpose of yubikey
It seems all of your points rely on the fact that is still unclear to me, how can it possibly work if each time it generates a new password? It's not like every program that needs a password is specially designed to handle the case of a Yubikey.

That's interesting, I wonder what is it about Firefox that it can't leave the page even by trying to close the browser.
