Identity and Access in the Cloud: Start With Least Privilege

Identity Is the New Perimeter

There is no office wall around a cloud environment. What stands between an attacker and your data is identity — who can log in, and what they can do once they have.

Getting It Right

Grant the minimum access each role genuinely needs, and nothing more. Protect every account — especially administrative ones — with multi-factor authentication. Prefer roles and short-lived credentials over long-lived keys, and never embed keys in code or config files. Review access regularly and remove what is unused.

Most cloud incidents trace back to an over-permissioned account or a leaked credential. Disciplined identity management is not the exciting part of cloud — it is simply the part that fails first when ignored.
