Enterprise Manager 12C as a Security Tool
Enterprise Manager (EM) is a three-tier application that is used by DBAs and their managers to centrally administrate a large database estate using a widely accessible web interface. EM allows reporting, monitoring, and administration on a large scale and can integrate application, DB, and OS tiers into a single system architecture. This makes EM a very powerful tool, as it reduces costs and increases efficiency and availability and can potentially decrease security risk. Database Control is a similar interface to EM but is limited to individual DB hosts, whereas EM grid/cloud control can scale up to manage many databases.
