Operationalizing least privilege: Automate IAM remediation through your CI/CD pipeline

The principle of least privilege is straightforward to articulate but challenging to maintain at scale. When teams first deploy applications to AWS, they often grant broader permissions than strictly necessary; it’s faster to get things working, and the plan is always to tighten permissions later. But later rarely comes.

Permissions accumulate, AWS Identity and Access Management (IAM) principals that once needed broad access for initial deployment retain those permissions long after they’re necessary, and some principals stop being used entirely. Even small teams face this challenge—permission reviews aren’t a one-time task but an ongoing operational burden that demands automation.
