The system failed. Not because of bad code, but because the wrong hands held too much power. This is the pain point of Separation of Duties. When critical controls are concentrated, the risk is multiplied. One person can bypass safeguards. One account can deploy, approve, and release unreviewed changes. That single gap can undo years of security work.
Separation of Duties exists to cut that risk out of the equation. It forces clear boundaries: who can write code, who can approve code, who can deploy code. It prevents overlap between conflicting functions. Developers should not approve their own pull requests. Release managers should not edit production directly. System administrators should not audit their own logs.
The pain point comes from how hard this is to enforce in real workflows. Multiple tools. Multiple cloud accounts. Shadow privileges granted during fire drills and never revoked. Fine-grained permissions scattered across CI/CD, source repos, infrastructure consoles. Without a unified approach, these controls decay. Roles blur. Engineers bypass bottlenecks to ship features faster, unintentionally dismantling safeguards.
