A DevOps administrator is building a new application slack in a private cloud.

The most useful tool in maintaining confidentiality for a new application stack that will store sensitive information and be accessible from the internet is data loss prevention (DLP). DLP is a type of security solution that monitors and controls the flow of data in and out of a system or network. It can detect and prevent unauthorized access, transmission, or leakage of sensitive data, such as personal information, financial records, or intellectual property. DLP can also enforce encryption, masking, or deletion of sensitive data to protect its confidentiality.
