At my Fortune 250, our threat model apparently includes -- rather conveniently and coincidentally -- everything! Well, everything they make an off-the-shelf product for, anyway. It makes new purchasing decisions easy:
"Does your product make any thing, in any way, more secure?"
"Uh... Yes?"
"You son of a bitch. We're in. Roll it out everywhere. Now."
This reminds me of our own security team, who as far as I can tell do nothing but run POC's of new security tools. And then maybe once a year actually buy one, generating a ton of work (for others) to replace the very similar tool they bought last year. Seems like a good gig.
Occasionally security products turn into malware delivery platforms as well, because they run very privileged, are sometimes more shoddily developed than what they’re protecting, and have fewer eyeballs on them than the vanilla operating system.
And then when there is a security issue you ask them share the log files from all their spyware and suddenly half the stuff needed is not there because we did not get that module.
Ahh, I've been there. I'm sure no concern is given for usability of the result.
Welding your vault shut may make it harder for thieves to break in, but if your business model requires making deposits and withdrawals, it's somewhat less helpful.
Luckily, all but tiny portion of security products have a door you can open if you ask support nicely enough you didn’t know about before. So you can still get your stuff after you weld the door shut.
I’m not privy to those discussions, but it certainly doesn’t feel like they’re happening. We implement every security “best practice,” for every project, no matter how big or small. We have committees to review, but not to assess scope, only to make sure everything is applied to everything. Also, we have multiple overlapping security products on the corporate desktop image. It feels EXACTLY like no one has ever tried to gauge what a compromise might cost.
