Easily. Such settings will be soon replaced by something useful. Similarly it can be said PC switched off is 100% secure. But such one is useless one.
easily, by human press to cancel such limited funtionality.
There will be always forced trade off between functionality and security. Any system is as strong as people let him to be, not as it could be. This trade off will be always a weakness by principle, not less serious than principial ability of PFW to be compromised.
Not proved. Well, most you say about PFW, can be easily applied to AV solutions. Would you persuade people not to use AV ? The fact there is no 100% secure sw solution of any kind ( and I have never claimed the opposite ) does not mean we should not use it. Would you not trying to cure a disease, just because there is no garance of success ?
Then there are suspicious data transactions between other already booted devices within so called secured LAN HW FWs do not care after. Who would care about FW in age of notebooks, palms, IR, wifi, bluetooth and all related stuff ? :-D
I think this discussion probably leads to nowhere. But I take it like an income, not lost. Glad to share opinions with all of you. Thanks for cooperation.
