You install software via ticket requests to IT, and devs might have admin rights, but not root, and only temporary.
This is nothing new though, back in the timesharing days, where we would connect to the development server, we only got as much rights as required for the ongoing development workflows.
Hence why PCs felt so liberating.
Just wait when more countries keep adopting cybersecurity laws for companies liabilities when software doesn't behave, like in any other engineering industry.
A breach can turn out into enough money being lost, in credibility, canceled orders, or lawsuits, big enough to close shop, or having to fire those that thought security rules were dumb.
Also anyone with security officer title, in many countries has legal responsibilities when something goes wrong, so when they sign off software deliverables that go wrong, is their signature on the approval.
