Data Loss Prevention (DLP) Checklist is a set of guidelines and best practices to help organizations protect their data from potential loss. It includes a variety of steps such as identifying and classifying data, creating acceptable use policies, implementing encryption, restricting access to data, and monitoring for data loss. The checklist can also cover physical security measures such as using external storage devices and controlling access to the premises. Additionally, organizations should also have a plan in place for data recovery in the event of a breach. By following the DLP Checklist, organizations can reduce the chances of data loss and ensure that their data is secure.
