Continuing our review of practices to protect cloud infrastructures from weaknesses that can be introduced from on-premises accounts, we consider admin rights, authentication, and conditional access policies. Plus the need to collect and analyze the log data available in cloud environments to make sure that nothing nasty is slipping through.
