:: It is not so clear. First of all there's no mention of OSI; moreover there's eight layers in the picture, not seven. "Foreign government" may still be at ISO Layer 1, e.g. at a chip fab, or somewhere higher such as in factory-installed firmware or OS image. "Own government" may be anything starting from installing hardware implants via interdiction, through firmware/OS/crypto compromise (planted vulnerabilities), 0-days (discovered vulnerabilities) to traffic capture/analysis - and so on. My personal take on layers' meanings is: HW design shortcomings; malicious firmware installed at foreign factories; NSA-planted APTs (low-level); malware infections; Javascript (or trojan app) mining code; backdoors planted in app code by a current employee; vulnerabilities in app code exploited by a former employee; user-inflicted problems such as misconfiguration or installation of questionable software -- [[User:Malgond|Malgond]] ([[User talk:Malgond|talk]]) 17:51, 24 June 2019 (UTC).

::: This is where I'm at on the question as well. It seems that connecting each tech stack layer to an OSI model layer is a too bit restrictive. [[User:Ianrbibtitlht|Ianrbibtitlht]] ([[User talk:Ianrbibtitlht|talk]]) 18:35, 24 June 2019 (UTC)

:::: Just wanted to add my thoughts, but I saw the eighth "user layer" as representing the human element, e.g. social engineering, and the fact its narrower than the other layers might indicate its supposed to not be standard.  In my mind, this would make sense as most companies have a support desk that doesn't realise its own role in security, and can therefore be compromised by a customer with little technical skill.  Maybe I'm clutching at straws to fit in in with the OSI model, but what other model is there that's well known enough?
