How can you guarantee a long trusted developer doesn't have a gun pointed to their head by their authoritarian govt?
In our B2B shop we recently implemented a process where developers cannot add packages from third party sources - only first party like meta, google, spring, etc are allowed. All other boilerplate must be written by developers, and on the rare occasion that a third party dependency is needed it's copied in source form, audited and re-hosted on our internal infrastructure with an internal name.
To justify it to business folks, we presented a simple math where I added the man-hours required to plug the vulnerabilities with the recurring cost of devsecops consultants and found that it's cheaper to reduce development velocity by 20-25%.
Also devsecops should never be offshored due to the scenario I presented in my second statement.
