comment how can I authenticate a process from kernel side?
I will not use a PID to flag the auth status since PIDs are limited in space and they are used circularly and so potentially the PID can be spoofed.

comment USB OTG DMA Attack vector, any information about that?
Ok thank you. Maynor replied to some of my enquiries and he told me nothing basically. I know that USB specification are public but I can't allocate the necessary effort on the spec. I trust your explanation. Thank you.

Do you know that because you know how USB works under the hood or what ?

comment USB OTG DMA Attack vector, any information about that?
Unfortunately I don't know how USB OTG works. My understanding is that with USB OTG and USB protocol exploitation you can have access to DMA. I contacted Maynor on Twitter but he didn't reply yet. In summary by the way, seems that in the paper are used wrongs and not so clear assumption.

comment Which key usages are required by each key exchange method?
With Openssl tls v1.2 if you don't use keyAgreement in KeyUsage field you are not allowed to establish ECDH but only ECDHE. I think the OP would to know things like that.

comment security metrics on softwares developed
I've studied most of these when I've got the CISSP. With a great likelihood probably I've to move in Gary McGraw's books.

comment security metrics on softwares developed
Ok, understood your point and with said purpose that make sense. it's always difficult to share with pure tech people what some numbers can communicate even if not 'tech founded'. At the moment I'm trying to push up my 'consultancy/managerial' sec skills. Do you have any suggestion about other books that are a MUST read on sec management ?

I totally disagree with your introduction but at the end I've chosen your answer, as unique answer to the question. To allow you to understand better why metrics are important I suggest to you to read this book: amazon.com/Security-Metrics-Replacing-Uncertainty-Doubt/dp/…

comment is there a way to indirectly uncharge rapidly a coin cell to defeat an anti tampering mechanism?
Indeed digging more in I've found that the anti-tampering mechanism for this device monitors the temperature.

What about increasing temperature/humidity of the room or something like that ?

comment security metrics on softwares developed
Say that perfect security doesn't exist, , find a way to measure/have an idea on how secure/insecure all software are it's by the way useful to move from FUD (Fear, uncertainty and doubt) to a more numeric way to achieve more (not perfect but more than before) security driven by by number. Suppose you have 40 software with many weakness reported in it, from which software do you start to fix ? which weakness ? On the next release, where do you focalize your effort to prevent/ fix/ enforce the occurrence of less weakness/vulnerabilities?

@Manipulator, in regards to what security metrics highlight it's just a point of view. Does BSIMM suggest some security metrics specific on secure software developments ?

comment libraries alternative to gcc stack-protector / fortity source feature on linux
No, compiler add pre/post function check on the code for canary etc, but the functional code for the canary check or fail are in the libc. They are respectively __stack_chk_guard/__stack_chk_fail .

There isn't nothing wrong with the built-in functionality, my constraint is that I can't link the glibc.

comment What lawful interception standards are used outside Europe?
In Italy, our provider implement Lawful Interception following the ETSI specification, so every provider have a common way to do LI. For my employer I'm get involved in the design of a software solution, with a functional requirement of compatibility with ETSI standard. So after reading some of that specification the curiosity about non-EU get in me. :)
